Recently I told my students that I expect to be around by 2040. If life is found in the Universe by then, I'll die happier. I am strong, even if with less hair and teeth. I am with my daughter these days, until my wife comes back from California, after her PhD Qualifiers in History.
No one, left alone me, can tell when the world will end. There have been many false predictions in the past. Now I find out that a gas cloud is in its way to hit the fan in SgrA* early next year. X-Rays flares are expected: Will that be the end?
I doubt it. I want to be around when life is found outside Earth!
