@Ilikemyname420: ""To reach the Andromeda galaxy at normal speed, it would take 785,200,000,000,000 years."

"What in the f*** is "normal speed"?"

I thought the same thing.

"Andromeda's timeline likely won't take this collision into account. Besides: our sun will have burned all terrestrial life 25 million years before the formation happens."

"Andromeda is going to collide with the Milky Way in 3.75 billion years, the Sun will turn into a red giant in 5 billion years....so where the hell is this 25 million year number coming from?"

Well, the sun will kill us long before it actually gets to the Red Giant stage, though it does seem like 25 million is a random number this guy picked. It's possible he looked this up somewhere and simply neglected to mention where here, but yeah, seems pretty random.
