There are those who think maybe in about 2 billion years more or less man will get smart enough to direct an astroid at the planet earth and knock it out of it orbit of the sun and be able to survive.
I swear I'm still laughing so hard at that I can barely type!
An asteroid impact would have an effect on the Earth nearly as bad as the Sun becoming a supergiant and swallowing the planet - a total extinction event.
In fact, without even doing any math, I would surmise that an impact forceful enough to
throw the Earth out of orbit would at the very
least result in fragmenting the planet, causing it to re-coalesce over a few million years, like when the moon was formed.
To save the Earth from the Sun's heat, we'll shoot it with the freaking
Death Star!
Oh, that's rich... Moving planets isn't exactly like playing pool, and you're talking about shooting a freaking .45 at the 8 ball!
Assuming humanity survives long enough, hopefully we'll figure out a way to get off of this rock and into space long before the Sun starts to run low on nuclear fuel. Honestly, if our species is still around in 2 billion years
and we're still on Earth, we'll deserve extinction.
Okay, enough of the off-topic discussion...
