James Morcan | 11362 comments Anyone aware of the theory that our solar system is a binary system and that there is another Sun in our solar system called Nemesis?
A brown dwarf star called Nemesis, so the theory goes...

Nemesis Star Theory: The Sun's 'Death Star' Companion https://www.space.com/22538-nemesis-s...
Nemesis is a theoretical dwarf star thought to be a companion to our sun. The theory was postulated to explain a perceived cycle of mass extinctions in Earth's history. Scientists speculated that such a star could affect the orbit of objects in the far outer solar system, sending them on a collision course with Earth. While recent astronomical surveys failed to find any evidence that such a star exists, a 2017 study suggests there could have been a "Nemesis" in the very ancient past.

Nemesis (hypothetical star) - Wikipedia https://en.wikipedia.org/wiki/Nemesis...
Nemesis is a hypothetical red dwarf[1] or brown dwarf,[2] originally postulated in 1984 to be orbiting the Sun at a distance of about 95,000 AU (1.5 light-years),[2] somewhat beyond the Oort cloud, to explain a perceived cycle of mass extinctions in the geological record, which seem to occur more often at intervals of 26 million years.[2][3]

The sun likely has a lost twin called ‘Nemesis’, as do most stars like it https://www.zmescience.com/space/sun-...

Nemesis, Earth's Evil Twin Sun
Nemesis Facts:
Nemesis is the name given to a theorized brown dwarf star that orbits the Sun at very far distance.
It is believed that when Nemesis comes close, it causes a disaster on Earth such as the extinction of the Dinosaurs
As it is a brown dwarf, it is very hard to spot in the cosmos of blackness.
The Name Nemesis comes from the Greek Goddess of Divine Retribution.

That was exact same article I posted above...
Not sure that article, or any other scientific studies, have debunked this issue, even tho as stated it's just some hypothetical dwarf star... Wikipedia does state some astronomers (albeit in the minority) support the theory of Nemesis' existence: "Two teams of astronomers, Daniel P. Whitmire and Albert A. Jackson IV, and Marc Davis, Piet Hut, and Richard A. Muller, independently published similar hypotheses to explain Raup and Sepkoski's extinction periodicity in the same issue of the journal Nature."

However, I always love your confidence, Dave!

David Elkin | 508 comments you gotta be convinced. Here is how this came about: http://muller.lbl.gov/pages/lbl-nem.htm

And yet the theory, according to the following article on a physics site, mentions "One other proposal that has been put forward is that the sun has a companion star, called Nemesis. Nemesis is a hypothetical, faint red/brown dwarf star orbiting the sun at a distance of about 1.5 light years. Every 25m years or so, it makes a pass closer to the sun, which could result in enhanced comet activity, because of its gravitational pull. This is not an unreasonable hypothesis, since the majority of stars belong to systems with multiple stars. However, brown dwarfs are relatively uncommon and Nemesis has not been observed (yet)."

Did 'dark matter' or a star called Nemesis kill the dinosaurs? https://phys.org/news/2015-12-dark-st...

David Elkin | 508 comments agreed, this is a a different take on mass extinctions

"So is there any evidence of this in the geological or palaeontological record? While the issue is still under debate, there is no conclusive evidence that extinctions have happened periodically. Randall's team claims the boost in comets may happen every 35m years or so, which some might argue could roughly correlate with mass extinctions."
