when are polar bears going extinct?
So, to answer your question, my best guess is that polar bears could go extinct somewhere between 2050 and 2100.

Can dark matter form life?
Ordinary matter is unduly influential given its meager abundance because it collapses into a dense matter disk where stars, planets, the Earth, and even life could form. A charged dark matter component—though not necessarily quite as bountiful—can collapse to form disks like the visible one in the Milky Way too.
Will we run out of helium?
Once the gas leaks into the atmosphere, it is light enough to escape the Earth’s gravitational field so it bleeds off into space, never to return. We may run out of helium within 25–30 years because it’s being consumed so freely.
