One scientist proposed removing mass from our star to make it last longer.

But then there's the cycle of mass extinction every 65M years, so any thing beyond the concept may be moot.

And there's always the possibility of a Shoemaker-Levy 9, or an Apophis ruining some people's day.

I suppose we, er, the Earth can be swallowed by a black hole, or not survive a galactic collision.

And let's not forget a massive GRB from a "close" supernova...

Removing mass from the sun? That’s a new one on me. If mankind is around in millions of years I assume they’ll be able to adjust the orbit of the earth as the sun expands.

One scientist proposed removing mass from our star to make it last longer.

If we can do that, we can move the planet to a more habitable orbit and simply adjust as the star adjusts.

Besides, there's a galaxy out there to be colonized.
