My actual guess is a dead star orbiting the mother star..................
There's no way to 'prove it' without getting a probe there, which we can't do. The possibility of an alien megastructure has been all but ruled out. My guess is, the dimming Tabby's Star is due to a giant kitty.
Again, the sheer number of planets in the universe is not evidence in itself. Most of them will be around stars that are unstable flare stars, multiple star systems, don’t have enough heavy elements, or are too short-lived. Then there are the planets themselves. Most will not be in the habitable zone, are gas giants, have no water, etc. It is said that without a moon the size of ours, Earth’s tilt would be too unstable for life. We don’t know how rare that is in the universe. There is also a magnetic field that is needed, perhaps a fractured crust, etc. etc. There could be dozens, hundreds, or thousands of other factors which would make life impossible. Earth itself has had several extinction events which very nearly wiped out all life. I don’t think it’s pessimistic to consider this, I think it’s realistic.
Exactly! ...also, one complete with bias toward intelligent life being out there, primarily because “wouldn’t it be cool!”.
I agree it would be cool, but that’s not evidence!
However, thinking that way does get you on TV, the Internet and the rest of the media. Isn’t that’s what really is important being on TV, etc.?
“he doesn’t think the so-called “grays” are actually real, but are perhaps AI beings, biological robots, or semi-material projections”
We are like little kids playing with toys we do not understand.
The human definition of “real” may be just one of our major errors in epistemology.
If I were part of a high tech civilization and advising the leaders on how to deal with this planet I would advise them to observe using camouflage nanotech—no way would I want to initiate “contact” with a planet of vicious and insane savages.
Forget about the question of “intelligent life”, right now the cosmologists are not at all sure that the Big Bang actually happened. There are many holes in this long-standing theory. The latest problem is, the James Webb telescope is apparently finding fully formed galaxies in the early universe which shouldn’t be there.
What evidence did he cite?
Of more relevance is that those billions of stars are so far away as to make this moot as an issue or phenomenon for us.
Any pile of debris dense enough would have to be immense and far away from the star so that the phenomenon would remain stable. So your dead star or very large non-stellar companion, being smaller, would have to be orbiting close enough to block that 22% of its light.
A black hole might explain it, but then the visible star would also show a wobble (to say the least) and lensing, and neither is present AFAIK.
Maybe the star has lost luminosity on one side, due to some kind of, uh, encounter, or other phenomenon.
Yup, even if there is still life in other galaxies, they are separated from us by millions or billions of years even at the speed of light.
The reason this is being studied and discussed is, the sheer volume of stars is so vast and has grown so much, that the ability to ascertain exact characteristics hasn't been reached yet. You're speaking as if you know, and if you did, you'd be the only one.
S.E.N.D..M.O.R.E..C.H.U.C.K..B.E.R.R.Y..........
They would NUKE IT FROM ORBIT .... JUST TO BE SURE..........................
Kaku discussed the emergence of intelligent life on Earth, noting that the dinos seem to never have had any during their 200 million years, and Tabby's Star dimming, and the exoplanet count (5000), and that 20 Earthlike ones are known.
Thousands more candidates have been identified but not yet verified (it will take a while, obviously, due to observatory capacity).
NASA's exoplanet page: "Since the first exoplanets were discovered in the early 1990s, the number of known exoplanets has doubled approximately every 27 months."
The problem here is not observational, it's psychological -- 'we can't get there, so no reason to look'; 'conditions on Earth were perfect (not until 200,000 years ago though) and WON'T be found ANYWHERE ELSE no matter HOW HARD YOU LOOK',; etc.
Exactly.
Are there no intelligent editors these days?
Well I do know that most stars are unstable red dwarfs. Also that most are binary or multiple star systems. I also know that most exoplanets are not located in a habitable zone. That’s common knowledge. What I do not know, nor does anyone, is the number of other conditions which might render a planet uninhabitable. They could be great or small. But as I said, the sheer number of exoplanets is not evidence of anything, nor does the lack of evidence constitute evidence in itself.
My pleasure.
Michio Kauku - a non-serious populace scientist in all of the last two decades of his noteriety. Once he got so popular he has to tended more to the truly pure anti-emperical speculation. I barf every time I hear him on TV.
Thanks for the partial list of requirements for life. It’s clear that there are many stars, but that the chance origin and sustainment of life is infinitesimally small. How this plays out in the Drake equation is a matter of speculation IMO.
There are some people who really don’t want to believe in extraterrestrial life. There are those, many more I think, who really want to believe in extraterrestrial life.
I saw Kaku on TV and he proceeded as though an infinite number of universes was a matter of fact, not speculation. That is one way to blow up the numerator in the Drake equation. As far as I know, there is no reason to believe that there is more than one universe.
