WHAT THE FUTURE HOLD
So have you heard that thing about andromeda colliding with the milky way? It would obviously happen a LONG time from now, but I'm wondering if our solar system will even last long enough to see it. Like will our sun last long enough to get us there?
It will happen quite a long time from now (about four billion years), but yes, our sun will still be there. It won’t be a red giant yet, but it will be considerably warmer and brighter than it is now, as it will be nearing the end of its life as a main sequence star.
For a while beforehand, Andromeda will grow larger than larger. At some point, the Milky Way and Andromeda will get so close that they will begin to gravitationally distort each other. The night sky will look like this (albeit somewhat dimmer to our eyes):
However, by this time, the sun will be about 40% more luminous. The habitable zone, a ring around the Sun where liquid water (and life as we know it) can exist, will have moved further out into the solar system. Earth will be too warm for liquid water. The oceans will have evaporated, and life on Earth will fade away into memory. Of course, humans are getting more and more advanced all the time. Considering how far we’ve come in just a hundred years, if we don’t manage to kill ourselves first (which is a big if), and if the current trends in the rate of advancement in technology hold, it’s virtually certain that our technology will be so advanced that preserving life on Earth will be trivial.
