In about 4-5 billion years, the Sun will run out of hydrogen fuel and will start expanding and turning into a Red Giant. Temperatures on Earth will reach thousands of degrees, the sunlight will become blindingly bright, our oceans and atmosphere will evaporate, we might get swallowed up by this Red Giant... pretty much, if we stay on Earth, we're doomed. Do you think humankind will be around to see that happen? If so, what do you think we will do about it?
Ahhh, so depressing...
