The βAndromedaβ galaxy, which is about twice the diameter of our galaxy, the βMilky Wayβ, will collide with us in approximately 4.5 billion years. Because the βAndromedaβ galaxy is of a greater mass and density than us, it is predicted that it will cannibalise the βMilky Wayβ. So are we all doomed? According to NASA, it is estimated that the merger of these two galactic behemoths will totally change the appearance of our night sky but will likely leave our solar system unharmed.
Great news right? Unfortunately, in 4.5 billion years when this merger happens, it is predicted that our sun will have nearly depleted its hydrogen fuel source and will have morphed into a red dwarf, growing in size out past Mercury, Venus and yes, you guessed itβ¦.. Earth!
So, one way or another weβre going to have to get humanity off this ball of rock! What do you think? Will humanity be able to survive these coming apocalypses, or will we be long gone by then?
