    I'm surprised anyone thinks we'd have a chance of survival. I don't think we'd last any amount of time, the sun is of fundamental importance to us. It's not just our most important energy source but our only energy source. Without it we'd be 100% doomed, and in any case a pitch black and bitterly cold world wouldn't be worth living in anyway. Even the earth's magnetic field is vital to us for it's shielding effect, removal of that would leave us in deep doodoo never mind taking the sun away!

    The moon moves approximately two inches away from the earth every year. This is due to the tidal bulges pushing the moons orbit out slightly giving it a spiral orbit around the earth.

    So realistically we will probably see the moon fire off into space before the sun.

    What would happen without the moon though?

    There would be no more ware wolves for one:D

    Absence of tides would presumably cause major issues for the marine ecosystem but what effect it would have on us is hard to gauge. We can assume that it wouldn't be good though. However the timeframe for the moon's departure is estimated at about 50 billion years, by which time the earth will have been fried or swallowed up by the sun anyway, and humans will almost certainly be long gone and long forgotten.

    We could not survive without the energy of a sun. But we may be able to live on Mars before our sun swells and engulfs earth. our sun will burn for a long time yet. Yet it will not go nova because it is too small but it will collapse eventually and die. Much later when the milky way collides with the Andromeda galaxies there is a small chance it will be swept away by the more powerful gravitational pull of a younger star, and who knows.. maybe it will be the foundation of a cluster of mater that develops slowly orbiting this unknown star. Maybe it will turn into a planet at some point in what we like to refer to as the future, life will flourish an the surface of a lush planet with our sun at its core. Either way, life is more accurately looked upon as a whole, of which human life is the same. It does not matter if life expresses it self in human form of anything else, life is constantly developing and we will not resemble anything like we do now when our sun dies. Edit: if humans survive that long.
