Is planet 'Tyche' actually Nemesis?

Asked By: trytobethere 22-25, M 5 months ago

Planet Tyche is causing comets to dislodge from the Oort cloud and towards Earth. Look it up in the news. They're saying it is causing mass extinctions.

Tyche is a "hypothetical" planet. Nemesis is a "hypothetical" star. Both are unproven.

Actually, Ms. Delilah was right in the manner that she described Nemesis as a potential star in a double star system with the sun!

Nemesis is postulated (but not proven) as being another star in the Milky Way galaxy that interacts with the sun's own gravity, such that the two move as a two-star system. This was postulated by Louis Alvarez in the 1980's, because mass extinctions of early plants and animals seemed to follow a fairly regular pattern of about every 60 million years. (Even the fishes suffered the same extinction pattern.)

Louis Alvarez was the person who theorized that the latest extinction of the dinosaurs occurred because a comet or meteor hit the earth in the vicinity of the Yucatan peninsula, some 26 million years ago. This collision threw up so much dirt into the atmosphere that it blocked the sunlight for a long time and killed the dinosaurs. He discovered that, all over the earth, in the rock formations there was a layer of clay-like material -- below which lay the dinosaurs, and above which there were no dinosaurs. Contained in the clay were traces of the element Iridium, a fairly rare element which had been similarly found around other crater remnants on earth.

Alvarez ran a computer simulation wherein the sun and a postulated other star (which he named Nemesis) slowly revolved around one another with a period of about 60 million years. His computer simulation technically viewed the sun from a fixed position, with the planets and Oort cloud surrounding the sun.

After a while, the second simulated star was made to pass nearby (still many light years away from our sun), and gravitationally disrupt the Oort cloud and send a shower of comets or meteors inward towards the sun.

Enough of my rambling.

No. Do you know what nemesis means? It's a righteous infliction of retribution manifested by an appropriate agent.

And do you know what Tyche is? It's a gentle and non-violent/non-contact martial art practiced by retirement-age Asians to keep their joints mobile and their circulation freely flowing.

The two things are not even related!

Mass extinctions of what?

Asking whether a hypothetical massive planet is actually a hypothetical very small star seems.... preemptive. Why not wait til we actually find anything before we decide what it is?

I thought Miss Marple was Nemesis. As to Tyche, I know it's been proposed, but have they actually found it?
