Highlighted by astronomers at the University of Rochester and the European Southern Observatory, the star — nicknamed “Scholz’s star” — has a very low tangential velocity in the sky, but it has been clocked traveling at a breakneck speed away from us.
In other words, from our perspective, Scholz’s star is fleeing the scene of a collision with us.
“Most stars this nearby show much larger tangential motion,” said Eric Mamajek, of the University of Rochester. “The small tangential motion and proximity initially indicated that the star was most likely either moving towards a future close encounter with the solar system, or it had ‘recently’ come close to the solar system and was moving away. Sure enough, the radial velocity measurements were consistent with it running away from the Sun’s vicinity — and we realized it must have had a close flyby in the past.”
...
Using data from the Southern African Large Telescope (SALT) and the Magellan telescope at Las Campanas Observatory in Chile, Mamajek and his collaborators were able to measure the star’s spectra and radial velocity. Through these observations they were able to deduce that Scholz’s star is a dim red dwarf approximately 20 light-years away. It is actually part of a binary system, with its partner being a small brown dwarf (or a ‘failed star’).
Taking these data, the researchers were able to model several different orbital possibilities and deduce that the star almost definitely (to a 98 percent certainty) came within 0.8 light years from the sun. Although this is still quite a margin, the star would have careened though the Oort Cloud — a hypothetical region filled with frozen cometary nuclei surrounding the solar system.

“I’m an engineer. I apply science to create things. I build a machine, set it in motion, and from that starting point & rules behavior emerges. I do not build the machine “mid-flight”...”
You are an engineer. Maybe God is an AUTHOR.
“There is nothing wrong with looking at the consequences of something happening and deducing the history thereof. Of course science can investigate history: we can look at how things are, look at how things behave now, and conclude the same rules governing behavior now would, given sensible starting conditions, produce things the way they are now.”
You seem utterly oblivious to the point. You ASSUME a mechanical process that involves no input from God, and then make deductions based on your assumption. But the assumption that God is an engineer who built a machine and then let it run mechanically without any input from him is YOUR assumption.
You can make that assumption and proceed from there if you wish, but you cannot complain that God is a liar because He doesn’t submit to your rules.
It’s not about “my rules”. I’m not asserting “my rules” at all. I never said God doesn’t interact with his creation.
If you’re going to accuse me of such, you’d better start quoting my posts.
I’m asserting there is a truth of what the universe is and how it functions, and that what it is & how it works speaks much of its creator - a wonderous story indeed.
I’m asserting that the act of creating the starting point of the universe was absolutely and totally a matter of input from God. To initiate such a wondrous creation was absolutely a work of divine brilliance.
I _will_ call God a liar if His creation was designed to look like something it isn’t, for the purpose of deceiving me of the truth, and punishing me for accepting as real what I perceive.
Does the Moon exist? you’ve never been there, you’ve never touched it. Is it just a painting on a backdrop? Can you praise God for the brilliant creation of the Moon when you have no reason to believe it exists other than Moon-indicating photons happen to strike you eyes when you look in a certain direction? What grandeur do the stars proclaim if the light seemingly from them was set in motion without them?
Does God create fiction? or fact? Are we living in a divine _Truman_Show_, all things faked to see how we react?
Tell me: what is real? how can you trust God if nothing is?
Could one of those impacts been the Barringer crater in our southwest of about 50,000 years ago? Would that be the right amount of time to travel from the Ort Cloud? Or perhaps the cluster of impacts that took place in Argentina a little over 4,000 years ago that may have been the cause of the disastrous First Intermediate Period in Egypt described so eloquently by Ipuwer.
Ooh, tell me more about the Argentine impact cluster!
50,000 years would be more than enough time for a comet to travel from the purported Oort cloud. Long-period comets (like Kohoutek) have orbital periods in that ballpark.
My view is, the stuff that hits the Earth is mostly nearby, and that the periodicity of impacts is illusory — they happen when they happen, and the greatest threats are near enough for us to identify them and do something about them.
I Googled and first entered “Argentine Impact Craters” where there are a number of interesting listings. I determined that the one I had noticed before was the Campo del Cielo field, so added that to the first title. Here is one of the articles posted there. It seems that testing of burned wood samples under meteorites gives an age of 2200 to 2700 BC, which is about right for Ipuwer’s time.
Have fun checking out these sites, and they also have material related to other parts of South America.
Thanks g.

I looked at the 4th post listed, which was from 2008, and saw your comment #49 which mentions an event 10,000 years ago. There is also an event from 10,000 years ago mentioned for Argentina, Rio Cuarto I think. You have already posted in the past about the 2 mile wide crater in the Iraq Marshes which was around 2,000 BC. As we know from the Shoemaker/Levy event recently on Jupiter, it is quite possible that there were multiply events worldwide for both these time periods. Now back to the other 3 posts (after lunch ;-) ).
That was 2200BC.
Disaster That Struck The Ancients
Looking for 'swarms' is smart.
I clicked your link and found that your Comment #15, last line mentions the Argentinian impacts. I also decided to Google Ipuwer and have found this entire text of his report on the disaster.

I had to look it up to put this close call of 0.8 light years in perspective. Pluto is about 6 light HOURS away. I’m not sure what the oort cloud is all about, but I’m not sure any disturbances that far away would have had much effect on the earth.
The gravity of the passing sun would have been so small to have had no effect on our solar system.
The wikipedia entry agrees, and the footnotes lead somewhere useful:
> We show that given the low mass and high velocity of the binary system, the encounter was dynamically weak. Using the best available astrometry, our simulations suggest that the probability that the star penetrated the outer Oort Cloud is $\sim$98%, but the probability of penetrating the dynamically active inner Oort Cloud ($<$20 kAU) is $\sim$10$^{-4}$. While the flyby of this system likely caused negligible impact on the flux of long-period comets, the recent discovery of this binary highlights that dynamically important Oort Cloud perturbers may be lurking among nearby stars.

The binary is rocketing along one light year every 3645.8 years.
The dating of the Papyrus Ipuwer (which contains descriptions of phenomena obviously resembling or identical with the OT Ten Plagues) is known, but as it is a copy of the earlier original, the era of its original composition remains a little controversial. The 2nd IP fits the date of the Exodus and has grown in popularity, while a the 1st IP date was the original estimate, and the latter makes no sense at this point. Donovan Courville, in “The Exodus Problem and Its Ramifications”, proposed that the Exodus happened in *both* the 1st and 2nd IP, and that the two periods were simultaneous, but that isn’t based on much. The physical date of the papyrus that has survived is New Kingdom.

Ancient drought ‘changed history’

Scientists have identified a major climate crisis that struck Africa about 70,000 years ago and which may have changed the course of human history. The evidence comes from sediments drilled up from the beds of Lake Malawi and Tanganyika in East Africa, and from Lake Bosumtwi in Ghana. It shows equatorial Africa experienced a prolonged period of drought. It is possible, scientists say, this was the reason some of the first humans left Africa to populate the globe.
What blam said. :’)
