"Sun's Nemesis Pelted Earth with Comets, Study Suggests"
a dark object may be occasionally kicking comets in our direction. Nicknamed "Nemesis" or "The Death Star," (and now Tyche?) this undetected
object could be a red or brown dwarf star, or an even darker presence several times the mass of Jupiter.
why do scientists think something could be hidden beyond the edge of our solar system? priginally, Nemesis was suggested as a way to explain a cycle
of mass extinctions on Earth in the geological record, which seem to occur once per 26 million years.. Nemesis orbits the Sun at a distance of about
50,000 to 100,000 AU (about 0.8-1.5 light-years), somewhat beyond the Oort cloud.

Well, first of all this is just plain wrong, if Earth's 5 mass extinctions occur every 26 million years we are more than double past due for the 6th
one, the last one occurring 65 million years ago. In fact if you do a little math, you are suggesting that the first 3 mass extinctions happened
during the couple hundred million years the dinosaurs roamed the earth so this is clearly wrong.
If, IF this Brown Dwarf star of DEATH was hurling comets and crap towards us then what does it matter? We've always played dodgeball with stuff from
space. Big bro Jupiter usually steps in to sort out the bullies. What makes you think we see more space rockcakes than we've always done?.
Nemesis is an outdated hypothesis. As you mentioned it depended on a periodicity to mass extinctions. This was found not to be true, and coupled with
other observations caused the Nemesis hypothesis to be disregarded. The founders of Nemesis hypothesis (Whitmire and Matese) now support the Tyche
hypothesis. This is a large planet 25,000 AU away that is used to explain the orbits of long-period comets. It has nothing to do with mass extinctions
and currently has few supporters outside Matese and Whitmire.
funny that at the end of the article they say this:
“I don't suspect we'll have completed the search for candidate objects until mid-2012, and then we may need up to a year of time to complete
telescopic follow-up of those objects,” said Kirkpatrick.
Neither Kirkpatrick nor Wright think Nemesis is disrupting the Oort cloud and sending comets towards Earth, however. Because they envision a more
benign orbit, they prefer the name "Tyche" (the good sister).
