@TheIntern55 Always glad to cheer another old salt up. :-)
But I am hard pressed to answer whether it’s better to worry about non-existent zombies of the Red Giant phase of the sun, which is very real but won’t happen for billions of years.
@ragingloli I write degrees Kelvin because too many readers wouldn’t know it was a temperature measurement without the word “degrees” being included. And as to humans surviving 8 billion years, my DNA plans to. Speak for yourself on that. :-)
@woodcutter If we don’t know how to terraform and move planetary orbits, we will be doomed when the sun begins to run out of fuel. In its red Giant phase, all the inner planets will be so hot no living organism could survive. After it burns up its hydrogen and becomes a white dwarf, we’d need to be in an orbit like that of Mercury to survive. Most of the solar system will be at very near absolute zero.
Star Trek and other science fiction may have inspired your confidence in warp drive, but the fact is that the technology and energy levels required to generate the sort of gravitational well necessary to warp many light years of space time into a short distance far exceed the technology and energy levels needed to move a planet a few astronomical units over a period of billions of years.
