0:03 · for decades scientific projects like
0:05 · SETI have been looking for evidence of
0:08 · extraterrestrial civilizations but now
0:11 · we have learned that perhaps they've
0:13 · been looking for the wrong thing since
0:16 · the beginning SETI has concluded or at
0:19 · least some scientists at SETI have
0:21 · believed that the most likely way that
0:24 · extraterrestrial civilizations would
0:26 · communicate with one another is
0:28 · utilizing the same technologies that we
0:30 · use that is to say narrowband radio
0:34 · transmissions however in February of
0:36 · this year NASA received a laser message
0:39 · from a spacecraft in deep space spanning
0:43 · 16 million kilometers however this
0:46 · signal did not originate from an
0:48 · extraterrestrial civilization or an
0:51 · alien spacecraft or anything along those
0:54 · lines but a NASA spacecraft on its way
0:57 · to the asteroid belt called Psyche
1:00 · unlike traditional radio signals this
1:03 · transmission came from advanced
1:05 · technology called the deep space optical
1:08 · communications experiment or dock which
1:11 · utilizes near infrared lasers to send
1:14 · data at speeds 10 to 100 times faster
1:17 · than conventional methods that NASA has
1:20 · used in the past so of course it has
1:23 · occurred to SETI and organizations like
1:25 · them indeed it occurred to them quite
1:28 · some time ago that alien civilizations
1:31 · might use a similar technology to
1:33 · transmit information as opposed to using
1:36 · outdated radio communications and thus
1:39 · was born optical SETI and after an
1:43 · extensive survey of the sky well one of
1:47 · several a particular survey has turned
1:49 · up something quite fascinating a
1:52 · repeating signal not from one star but
1:55 · two signals that have completely defied
1:58 · all natural explanation and may finally
2:02 · be definitive evidence that we are not
2:05 · alone in the universe
2:12 · good afternoon alien enthusiasts and
2:14 · welcome to another angry alien bulletin
2:18 · for decades the entire philosophy behind
2:22 · SETI's search for extraterrestrial
2:25 · intelligence that is to say when they
2:28 · have the money to invest in these sorts
2:31 · of searches is to look for radio signals
2:35 · narrow beam powerful radio signals and
2:38 · that tend to only come from artificial
2:41 · sources and also to look for those radio
2:45 · signals on specific frequencies that
2:48 · have to do with scientific principles
2:50 · that just about any intelligent species
2:53 · would understand for example radio
2:56 · frequency associated with hydrogen the
2:58 · so-called hydrogen line this of course
3:02 · is something that any intelligent
3:04 · civilization would understand because
3:06 · hydrogen is the most common element in
3:08 · the universe or perhaps a frequency
3:11 · associated with the hydrogen line say
3:14 · the hydrogen line frequency times pi
3:17 · both of which of course would be
3:19 · concepts that any civilization would
3:22 · understand or perhaps the square root of
3:25 · the hydrogen line something that should
3:29 · be understandable for just about any
3:32 · civilization that understands the basics
3:34 · of the universe and the basics of
3:36 · mathematics but still there's no
3:38 · guarantee that intelligent civilizations
3:41 · would use radio frequencies to
3:44 · communicate i mean sure it makes a lot
3:46 · of sense to us to use these sorts of
3:49 · things but is that the sort of medium
3:52 · that every civilization would make use
3:55 · of might there be other alternatives
3:58 · well this is what a specific project uh
4:02 · associated with SETI known as optical
4:05 · SETI decided to pursue to look for
4:08 · potential laser communications
4:11 · throughout the cosmos as a matter of
4:13 · fact we humans are now using lasers to
4:17 · transfer information over vast distances
4:20 · our current probe that we have heading
4:22 · out to the asteroid belt has been
4:25 · testing this type of technology and so
4:27 · far it's been working out very well
4:29 · however to be able to communicate
4:32 · information over enormous distances
4:35 · light years and light years you would
4:37 · need to have incredibly powerful lasers
4:41 · that can outshine suns and not only that
4:45 · these lasers would also have to be very
4:47 · specifically targeted if you say wanted
4:50 · to send a communication from some sort
4:53 · of distant star say 50 light years away
4:56 · to Earth let's say that aliens decided
4:58 · that they wanted to try to communicate
5:00 · with us well they would have to be
5:02 · really precisely on target because it
5:06 · would take 50 years for the signal to
5:08 · get from their star to ours and it would
5:11 · have to be a very narrow beam laser
5:14 · meaning that they would have to account
5:16 · for the movement of our solar system the
5:19 · movement of Earth in its orbit around
5:21 · the sun etc if you tried to use a laser
5:25 · with a wider beam that would have a
5:28 · larger area of detection well the amount
5:31 · of energy that would be required to
5:33 · power a beam that bright and that big
5:36 · would be just about impossible to
5:38 · accomplish it would require more power
5:40 · than all of human civilization has
5:44 · combined to generate a laser that
5:46 · powerful so really when it comes down to
5:49 · it optical SETI has been looking for two
5:52 · things number one a laserlike beam of
5:55 · light or just an extremely bright burst
5:58 · of light that can outshine a star but is
6:01 · a very brief thing things in nature you
6:05 · very seldom get something that only
6:06 · lasts a few seconds in nature something
6:09 · that bright supernova or a sudden
6:12 · brightening of a star those sorts of
6:14 · things last for days or weeks not just a
6:18 · few seconds but in addition to that they
6:21 · also want the signal to repeat that has
6:24 · been a frustrating requirement of SETI
6:28 · in order to confirm the artificial or
6:31 · intelligent origin of this sort of
6:33 · signal it has to repeat well guess what
6:37 · just recently that is to say a few weeks
6:40 · ago a paper came out from Optical SETI
6:42 · confirming that they had indeed found
6:45 · something just like that
6:50 · the paper in question concerns the
6:52 · results of a multi-year survey of more
6:55 · than 1300 sunlike stars for optical SETI
7:00 · signals and veteran NASA scientist
7:03 · Richard A stanton was behind this
7:05 · project dr stanton is a veteran of
7:08 · NASA's Jet Propulsion Laboratory whose
7:11 · work includes participating in the
7:13 · Voyager missions and serving as the
7:15 · engineering manager of the Gravity
7:17 · Recovery and Climate Experiment or Grace
7:20 · mission since retiring he has dedicated
7:23 · himself to the search for
7:25 · extraterrestrial intelligence utilizing
7:27 · the 76.2 2 cm telescope at the Shea
7:32 · Meadow Observatory in Big Bear
7:34 · California and a multi-channel
7:36 · photometer that he designed the paper
7:39 · describing his surveys findings is
7:42 · linked in the description for years
7:44 · Stanton has used these instruments to
7:46 · observe more than 1300 sunlike stars for
7:50 · optical SETI signals and as I mentioned
7:52 · before optical SETI looks for pulses of
7:55 · light that could result from laser
7:57 · communications or directed energy arrays
8:00 · such as project starshot that will
8:03 · utilize an array of high energy lasers
8:06 · to push probes or laser sails that is up
8:10 · to speeds approaching that of the speed
8:12 · of light now this study traces its roots
8:15 · to a 1961 study by Dr schwarz and Towns
8:19 · and they reasoned that the best way an
8:21 · extraterrestrial intelligence or ETI
8:24 · could send an optical signal that
8:27 · outshone their star would be with
8:29 · intense nancond laser pulses other
8:32 · optical SETI searches look for signals
8:35 · in infrared wavelengths high resolution
8:38 · spectra or visible light as Stanton
8:41 · related to Universe Today via email his
8:44 · said he searched differs from
8:46 · conventional optical surveys quote "My
8:48 · approach is to stare at a single star
8:51 · for roughly 1 hour using photon counting
8:54 · to sample the stars light at what is
8:57 · considered to be a very high time
8:59 · resolution for astronomy 100 microscond
9:03 · samples the resulting time series are
9:05 · then searched for pulses and optical
9:08 · tones the instrument uses readily
9:10 · available off-the-shelf components that
9:13 · can be assembled into PCbased systems
9:16 · after years of searching Stanton noticed
9:18 · an unexpected signal on May the 14th
9:21 · 2023 while observing star HD89389
9:27 · an F-Type star slightly brighter and
9:30 · more massive than our sun located in the
9:33 · constellation Ursa Major otherwise known
9:36 · as the Big Dipper according to Stanton's
9:39 · paper this signal consisted of two fast
9:43 · identical pulses 4.4 seconds apart that
9:47 · were not revealed in previous searches
9:49 · he then ran comparisons against signals
9:52 · produced by airplanes satellites meteors
9:55 · lighting atmospheric scentilation system
9:58 · noise and other possible mundane
10:01 · explanations as he explained several
10:04 · things about the pulses detected around
10:06 · HD 89389
10:09 · made them unique from anything else seen
10:12 · previously first of all the star gets
10:14 · brighter and fainter and brighter and
10:17 · then returns to its ambient level all in
10:20 · about 2 seconds this variation is much
10:24 · too strong to be caused by random noise
10:27 · or atmospheric turbulence how do you
10:30 · make a star over a million kilometers
10:32 · across partially disappear in a tenth of
10:35 · a second the source of this variation
10:38 · can't be as far away as the star itself
10:41 · number two in all three events two
10:45 · essentially identical pulses are seen
10:47 · separated by between 1.2 and 4.4 seconds
10:51 · a third event found in an observation on
10:54 · January 18th of this year was not
10:57 · included in this paper but it adds even
10:59 · more fascinating data to this study but
11:02 · in over 1,500 hours of searching no
11:06 · single pulse resembling these has ever
11:09 · been detected number three the fine
11:12 · structure in the stars light between the
11:14 · peaks of the first pulse repeats almost
11:17 · exactly in the second pulse 4.4 seconds
11:20 · later no one knows how to explain this
11:23 · behavior and number four nothing was
11:26 · detected moving near the star in
11:28 · simultaneous photography or in the
11:31 · background sensor that easily detects
11:33 · distant satellites moving close to a
11:36 · target star common signals from
11:38 · airplanes satellites meteors birds etc
11:42 · are all completely different from these
11:44 · pulses now of course all of this is
11:47 · pretty interesting an F-class star is
11:50 · bigger and hotter than our G-class star
11:53 · but located about 100 light years away
11:57 · so sort of a promising area to look for
12:00 · an intelligent civilization but not
12:02 · necessarily perfect but Stanton decided
12:06 · that it would be a good idea to
12:08 · re-examine historical data for similar
12:10 · signals and guess what he found another
12:13 · pair of pulses detected around star
12:16 · HD217014
12:19 · which is also known as 51 Pegasy on
12:23 · September 30th 2019
12:26 · this is a much closer main sequence
12:29 · G-type star this isn't just a similar
12:33 · star to ours it's almost precisely the
12:36 · same and it's located about 50.6 light
12:39 · years away as I said similar in size
12:42 · mass and age in 1995
12:46 · astronomers at the Oservatto de Hal
12:49 · Province detected an exoplanet orbiting
12:52 · this star a hot gas giant that has since
12:55 · been named Deidium this is one of the
12:58 · first exoplanets ever detected and was
13:01 · the first time an exoplanet was
13:03 · discovered around a main sequence star
13:06 · and of course where there's one planet
13:08 · there's probably more and at the time
13:11 · incredibly enough the signal was
13:13 · dismissed as a false positive caused by
13:16 · birds however a detailed analysis ruled
13:19 · out this possibility completely for all
13:22 · of the pulses observed other
13:24 · possibilities that Stanton explored
13:26 · included refraction caused by Earth's
13:29 · atmosphere possibly due to some kind of
13:31 · shock wave however this is highly
13:34 · unlikely since shock waves would have to
13:36 · occur with perfect timing to coincide
13:39 · with all three optical pulses and three
13:43 · identical optical pulses by the way with
13:46 · three identical shock waves in the
13:48 · atmosphere not very likely other
13:51 · possibilities include starlight
13:53 · defraction by a distant body in the
13:55 · solar system partial eclipses caused by
13:58 · Earth satellites or distant asteroids an
14:01 · edge defraction by a straight edge as
14:03 · described by the so-called Somerfeld
14:06 · effect and there's also the possibility
14:08 · that a gravity wave could have generated
14:10 · these pulses although this is a
14:12 · phenomena that we don't really
14:14 · understand but it still requires
14:17 · additional consideration but of course
14:19 · another interesting possibility and it's
14:22 · amazing to hear mainstream scientists
14:25 · talk this way is that it could be the
14:27 · result of extraterrestrial intelligence
14:30 · as Stanton indicated whatever modulated
14:33 · these stars light must be relatively
14:36 · close to Earth indicating that any ETI
14:39 · activity must be within our solar system
14:42 · moreover similar pulses have since been
14:45 · observed from another sunlike star
14:47 · located 81 light years from Earth
14:50 · HD12051
14:53 · and January 18th 2025
14:56 · to explain all three occurrences stanton
15:00 · stresses that more data is needed quote
15:03 · none of these explanations are really
15:05 · satisfying at this point we don't know
15:08 · what kind of object could produce these
15:10 · pulses or how far away it is we don't
15:13 · know if the two pulse signal is produced
15:15 · by something passing between us and the
15:18 · star or if it's generated by something
15:20 · that modulates the stars light without
15:23 · moving across the field until we learn
15:26 · more we can't even say whether or not
15:28 · extraterrestrials are involved but once
15:30 · again I find it very very interesting
15:33 · that they're talking this way at all but
15:36 · after exploring many many mundane
15:39 · explanations and coming up blank across
15:42 · the spectrum the paper concludes thusly
15:45 · quote "How are two nearly identical
15:48 · pulses generated separated by a
15:50 · relatively long interval of unaffected
15:53 · starlight the fact that these pulses
15:56 · have been detected only in pairs must
15:58 · surely be a clue as to their origin how
16:01 · can the two detected events separated by
16:04 · years and from seemingly random
16:07 · directions in the sky be so similar to
16:10 · each other whatever is found those
16:12 · speculating that our best chance of
16:14 · finding evidence of extraterrestrial
16:16 · intelligence lies within our own solar
16:19 · system might have much to ponder and
16:22 · when we're talking about our own solar
16:24 · system what if these pulses coming from
16:27 · seemingly random directions in the
16:29 · universe are not coming from random
16:32 · locations at all what if there's
16:35 · something about these signals that are
16:38 · specifically targeted towards us and
16:41 · further examination might reveal what
16:44 · they're actually trying to say and if
16:46 · they're expecting some sort of reply not
16:49 · necessarily from us
16:55 · intriguing stuff isn't it but
16:57 · unfortunately I have a feeling that like
17:00 · so many intriguing discoveries that have
17:02 · been made over the last several decades
17:05 · the scientific community is just going
17:06 · to let this one go they're not going to
17:08 · be able to find any sort of rational
17:12 · logical natural explanation for it so
17:15 · they're not of course going to say that
17:17 · this seems to be a really good candidate
17:20 · for something that originates from an
17:22 · extraterrestrial civilization instead
17:25 · they won't come to any solid conclusion
17:27 · they'll simply say "Oh most probably
17:29 · it's some sort of natural phenomenon
17:31 · that we don't understand." and then
17:32 · they'll just move on to something else
17:35 · instead of dedicating the necessary time
17:38 · the observation time focusing on these
17:41 · relatively nearby stars for a long
17:44 · period of time to confirm whether or not
17:46 · these signals might reappear again and
17:50 · again and interestingly enough if we
17:53 · spot these sorts of signals happening
17:55 · repeatedly what are they doing they
17:58 · trying to get our attention or might
18:01 · they be communicating with somebody else
18:04 · within our solar system somebody that
18:07 · they dispatched decades ago to check us
18:09 · out and now they're trying to get more
18:12 · information or issue instructions to
18:15 · their colleagues who are already here by
18:19 · the way folks in case you haven't
18:21 · noticed we got a new shirt here although
18:23 · this shirt has been around for a while
18:25 · check it out it is our Amua Mua merch
18:33 · i love this design guys it's absolutely
18:37 · fantastic and finally got it delivered
18:39 · to me personally but unfortunately the
18:41 · store closes on the 26th and although
18:45 · there has been an increase in Amuam Mua
18:47 · sales lately so I have a feeling that we
18:49 · probably will be able to offer it again
18:52 · next month I can't say that for certain
18:54 · so if you want to be sure that you get a
18:56 · piece of this merchandise well have to
18:59 · place your order by the 26th of June
19:02 · also I'm going to give away two of these
19:04 · shirts i got two spare extra-large
19:06 · shirts and I'm going to give two of
19:08 · those at random to people who have been
19:10 · supporting my trip to Australia on
19:13 · GoFundMe so if you've already made a
19:16 · contribution on GoFundMe or if you'd
19:18 · like to make a contribution to get me to
19:20 · Australia you will be entered into a
19:23 · drawing and there haven't been tons i
19:25 · mean we're talking less than 60 right
19:27 · now so your odds are pretty good if I'm
19:29 · giving away two of these shirts all the
19:32 · details are in the description thanks
19:34 · very much for watching please don't
19:36 · forget to like and subscribe and until
19:38 · next time stay angry about space

4:29	·	however to be able to communicate
4:32	·	information over enormous distances
4:35	·	light years and light years you would
4:37	·	need to have incredibly powerful lasers
4:41	·	that can outshine suns and not only that
4:45	·	these lasers would also have to be very
4:47	·	specifically targeted if you say wanted
4:50	·	to send a communication from some sort
4:53	·	of distant star say 50 light years away
4:56	·	to Earth let's say that aliens decided
4:58	·	that they wanted to try to communicate
5:00	·	with us well they would have to be
5:02	·	really precisely on target because it
5:06	·	would take 50 years for the signal to
5:08	·	get from their star to ours and it would
5:11	·	have to be a very narrow beam laser
5:14	·	meaning that they would have to account
5:16	·	for the movement of our solar system the
5:19	·	movement of Earth in its orbit around
5:21	·	the sun etc if you tried to use a laser
5:25	·	with a wider beam that would have a
5:28	·	larger area of detection well the amount
5:31	·	of energy that would be required to
5:33	·	power a beam that bright and that big
5:36	·	would be just about impossible to
5:38	·	accomplish it would require more power
5:40	·	than all of human civilization has
5:44	·	combined to generate a laser that
5:46	·	powerful so really when it comes down to
5:49	·	it optical SETI has been looking for two
5:52	·	things number one a laserlike beam of
5:55	·	light or just an extremely bright burst
5:58	·	of light that can outshine a star but is
6:01	·	a very brief thing things in nature you
6:05	·	very seldom get something that only
6:06	·	lasts a few seconds in nature something
6:09	·	that bright supernova or a sudden
6:12	·	brightening of a star those sorts of
6:14	·	things last for days or weeks not just a
6:18	·	few seconds but in addition to that they
6:21	·	also want the signal to repeat that has
6:24	·	been a frustrating requirement of SETI
6:28	·	in order to confirm the artificial or
6:31	·	intelligent origin of this sort of
6:33	·	signal it has to repeat well guess what
6:37	·	just recently that is to say a few weeks
6:40	·	ago a paper came out from Optical SETI
6:42	·	confirming that they had indeed found
6:45	·	something just like that
6:50	·	the paper in question concerns the
6:52	·	results of a multi-year survey of more
6:55	·	than 1300 sunlike stars for optical SETI
7:00	·	signals and veteran NASA scientist
7:03	·	Richard A stanton was behind this
7:05	·	project dr stanton is a veteran of
7:08	·	NASA's Jet Propulsion Laboratory whose
7:11	·	work includes participating in the
7:13	·	Voyager missions and serving as the
7:15	·	engineering manager of the Gravity
7:17	·	Recovery and Climate Experiment or Grace
7:20	·	mission since retiring he has dedicated
7:23	·	himself to the search for
7:25	·	extraterrestrial intelligence utilizing
7:27	·	the 76.2 2 cm telescope at the Shea
7:32	·	Meadow Observatory in Big Bear
7:34	·	California and a multi-channel
7:36	·	photometer that he designed the paper
7:39	·	describing his surveys findings is
7:42	·	linked in the description for years
7:44	·	Stanton has used these instruments to
7:46	·	observe more than 1300 sunlike stars for
7:50	·	optical SETI signals and as I mentioned
7:52	·	before optical SETI looks for pulses of
7:55	·	light that could result from laser
7:57	·	communications or directed energy arrays
8:00	·	such as project starshot that will
8:03	·	utilize an array of high energy lasers
8:06	·	to push probes or laser sails that is up
8:10	·	to speeds approaching that of the speed
8:12	·	of light now this study traces its roots
8:15	·	to a 1961 study by Dr schwarz and Towns
8:19	·	and they reasoned that the best way an
8:21	·	extraterrestrial intelligence or ETI
8:24	·	could send an optical signal that
8:27	·	outshone their star would be with
8:29	·	intense nancond laser pulses other
8:32	·	optical SETI searches look for signals
8:35	·	in infrared wavelengths high resolution
8:38	·	spectra or visible light as Stanton
8:41	·	related to Universe Today via email his
8:44	·	said he searched differs from
8:46	·	conventional optical surveys quote "My
8:48	·	approach is to stare at a single star
8:51	·	for roughly 1 hour using photon counting
8:54	·	to sample the stars light at what is
8:57	·	considered to be a very high time
8:59	·	resolution for astronomy 100 microscond
9:03	·	samples the resulting time series are
9:05	·	then searched for pulses and optical
9:08	·	tones the instrument uses readily
9:10	·	available off-the-shelf components that
9:13	·	can be assembled into PCbased systems
9:16	·	after years of searching Stanton noticed
9:18	·	an unexpected signal on May the 14th
9:21	·	2023 while observing star HD89389
9:27	·	an F-Type star slightly brighter and
9:30	·	more massive than our sun located in the
9:33	·	constellation Ursa Major otherwise known
9:36	·	as the Big Dipper according to Stanton's
9:39	·	paper this signal consisted of two fast
9:43	·	identical pulses 4.4 seconds apart that
9:47	·	were not revealed in previous searches
9:49	·	he then ran comparisons against signals
9:52	·	produced by airplanes satellites meteors
9:55	·	lighting atmospheric scentilation system
9:58	·	noise and other possible mundane
10:01	·	explanations as he explained several
10:04	·	things about the pulses detected around
10:06	·	HD 89389
10:09	·	made them unique from anything else seen
10:12	·	previously first of all the star gets
10:14	·	brighter and fainter and brighter and
10:17	·	then returns to its ambient level all in
10:20	·	about 2 seconds this variation is much
10:24	·	too strong to be caused by random noise
10:27	·	or atmospheric turbulence how do you
10:30	·	make a star over a million kilometers
10:32	·	across partially disappear in a tenth of
10:35	·	a second the source of this variation
10:38	·	can't be as far away as the star itself
10:41	·	number two in all three events two
10:45	·	essentially identical pulses are seen
10:47	·	separated by between 1.2 and 4.4 seconds
10:51	·	a third event found in an observation on
10:54	·	January 18th of this year was not
10:57	·	included in this paper but it adds even
10:59	·	more fascinating data to this study but
11:02	·	in over 1,500 hours of searching no
11:06	·	single pulse resembling these has ever
11:09	·	been detected number three the fine
11:12	·	structure in the stars light between the
11:14	·	peaks of the first pulse repeats almost
11:17	·	exactly in the second pulse 4.4 seconds
11:20	·	later no one knows how to explain this
11:23	·	behavior and number four nothing was
11:26	·	detected moving near the star in
11:28	·	simultaneous photography or in the
11:31	·	background sensor that easily detects
11:33	·	distant satellites moving close to a
11:36	·	target star common signals from
11:38	·	airplanes satellites meteors birds etc
11:42	·	are all completely different from these
11:44	·	pulses now of course all of this is
11:47	·	pretty interesting an F-class star is
11:50	·	bigger and hotter than our G-class star
11:53	·	but located about 100 light years away
11:57	·	so sort of a promising area to look for
12:00	·	an intelligent civilization but not
12:02	·	necessarily perfect but Stanton decided
12:06	·	that it would be a good idea to
12:08	·	re-examine historical data for similar
12:10	·	signals and guess what he found another
12:13	·	pair of pulses detected around star
12:16	·	HD217014
12:19	·	which is also known as 51 Pegasy on
12:23	·	September 30th 2019
12:26	·	this is a much closer main sequence
12:29	·	G-type star this isn't just a similar
12:33	·	star to ours it's almost precisely the
12:36	·	same and it's located about 50.6 light
12:39	·	years away as I said similar in size
12:42	·	mass and age in 1995
12:46	·	astronomers at the Oservatto de Hal
12:49	·	Province detected an exoplanet orbiting
12:52	·	this star a hot gas giant that has since
12:55	·	been named Deidium this is one of the
12:58	·	first exoplanets ever detected and was
13:01	·	the first time an exoplanet was
13:03	·	discovered around a main sequence star
13:06	·	and of course where there's one planet
13:08	·	there's probably more and at the time
13:11	·	incredibly enough the signal was
13:13	·	dismissed as a false positive caused by
13:16	·	birds however a detailed analysis ruled
13:19	·	out this possibility completely for all
13:22	·	of the pulses observed other
13:24	·	possibilities that Stanton explored
13:26	·	included refraction caused by Earth's
13:29	·	atmosphere possibly due to some kind of
13:31	·	shock wave however this is highly
13:34	·	unlikely since shock waves would have to
13:36	·	occur with perfect timing to coincide
13:39	·	with all three optical pulses and three
13:43	·	identical optical pulses by the way with
13:46	·	three identical shock waves in the
13:48	·	atmosphere not very likely other
13:51	·	possibilities include starlight
13:53	·	defraction by a distant body in the
13:55	·	solar system partial eclipses caused by
13:58	·	Earth satellites or distant asteroids an
14:01	·	edge defraction by a straight edge as
14:03	·	described by the so-called Somerfeld
14:06	·	effect and there's also the possibility
14:08	·	that a gravity wave could have generated
14:10	·	these pulses although this is a
14:12	·	phenomena that we don't really
14:14	·	understand but it still requires
14:17	·	additional consideration but of course
14:19	·	another interesting possibility and it's
14:22	·	amazing to hear mainstream scientists
14:25	·	talk this way is that it could be the
14:27	·	result of extraterrestrial intelligence
14:30	·	as Stanton indicated whatever modulated
14:33	·	these stars light must be relatively
14:36	·	close to Earth indicating that any ETI
14:39	·	activity must be within our solar system
14:42	·	moreover similar pulses have since been
14:45	·	observed from another sunlike star
14:47	·	located 81 light years from Earth
14:50	·	HD12051
14:53	·	and January 18th 2025
14:56	·	to explain all three occurrences stanton
15:00	·	stresses that more data is needed quote
15:03	·	none of these explanations are really
15:05	·	satisfying at this point we don't know
15:08	·	what kind of object could produce these
15:10	·	pulses or how far away it is we don't
15:13	·	know if the two pulse signal is produced
15:15	·	by something passing between us and the
15:18	·	star or if it's generated by something
15:20	·	that modulates the stars light without
15:23	·	moving across the field until we learn
15:26	·	more we can't even say whether or not
15:28	·	extraterrestrials are involved but once
15:30	·	again I find it very very interesting
15:33	·	that they're talking this way at all but
15:36	·	after exploring many many mundane
15:39	·	explanations and coming up blank across
15:42	·	the spectrum the paper concludes thusly
15:45	·	quote "How are two nearly identical
15:48	·	pulses generated separated by a
15:50	·	relatively long interval of unaffected
15:53	·	starlight the fact that these pulses
15:56	·	have been detected only in pairs must
15:58	·	surely be a clue as to their origin how
16:01	·	can the two detected events separated by
16:04	·	years and from seemingly random
16:07	·	directions in the sky be so similar to
16:10	·	each other whatever is found those
16:12	·	speculating that our best chance of
16:14	·	finding evidence of extraterrestrial
16:16	·	intelligence lies within our own solar
16:19	·	system might have much to ponder and
16:22	·	when we're talking about our own solar
16:24	·	system what if these pulses coming from
16:27	·	seemingly random directions in the
16:29	·	universe are not coming from random
16:32	·	locations at all what if there's
16:35	·	something about these signals that are
16:38	·	specifically targeted towards us and
16:41	·	further examination might reveal what
16:44	·	they're actually trying to say and if
16:46	·	they're expecting some sort of reply not
16:49	·	necessarily from us
16:55	·	intriguing stuff isn't it but
16:57	·	unfortunately I have a feeling that like
17:00	·	so many intriguing discoveries that have
17:02	·	been made over the last several decades
17:05	·	the scientific community is just going
17:06	·	to let this one go they're not going to
17:08	·	be able to find any sort of rational
17:12	·	logical natural explanation for it so
17:15	·	they're not of course going to say that
17:17	·	this seems to be a really good candidate
17:20	·	for something that originates from an
17:22	·	extraterrestrial civilization instead
17:25	·	they won't come to any solid conclusion
17:27	·	they'll simply say "Oh most probably
17:29	·	it's some sort of natural phenomenon
17:31	·	that we don't understand." and then
17:32	·	they'll just move on to something else
17:35	·	instead of dedicating the necessary time
17:38	·	the observation time focusing on these
17:41	·	relatively nearby stars for a long
17:44	·	period of time to confirm whether or not
17:46	·	these signals might reappear again and
17:50	·	again and interestingly enough if we
17:53	·	spot these sorts of signals happening
17:55	·	repeatedly what are they doing they
17:58	·	trying to get our attention or might
18:01	·	they be communicating with somebody else
18:04	·	within our solar system somebody that
18:07	·	they dispatched decades ago to check us
18:09	·	out and now they're trying to get more
18:12	·	information or issue instructions to
18:15	·	their colleagues who are already here by
18:19	·	the way folks in case you haven't
18:21	·	noticed we got a new shirt here although
18:23	·	this shirt has been around for a while
18:25	·	check it out it is our Amua Mua merch
18:33	·	i love this design guys it's absolutely
18:37	·	fantastic and finally got it delivered
18:39	·	to me personally but unfortunately the
18:41	·	store closes on the 26th and although
18:45	·	there has been an increase in Amuam Mua
18:47	·	sales lately so I have a feeling that we
18:49	·	probably will be able to offer it again
18:52	·	next month I can't say that for certain
18:54	·	so if you want to be sure that you get a
18:56	·	piece of this merchandise well have to
18:59	·	place your order by the 26th of June
19:02	·	also I'm going to give away two of these
19:04	·	shirts i got two spare extra-large
19:06	·	shirts and I'm going to give two of
19:08	·	those at random to people who have been
19:10	·	supporting my trip to Australia on
19:13	·	GoFundMe so if you've already made a
19:16	·	contribution on GoFundMe or if you'd
19:18	·	like to make a contribution to get me to
19:20	·	Australia you will be entered into a
19:23	·	drawing and there haven't been tons i
19:25	·	mean we're talking less than 60 right
19:27	·	now so your odds are pretty good if I'm
19:29	·	giving away two of these shirts all the
19:32	·	details are in the description thanks
19:34	·	very much for watching please don't
19:36	·	forget to like and subscribe and until
19:38	·	next time stay angry about space
