Milky Way and Andromeda Galaxies Collision Simulated | Video

Using data from the Hubble Space Telescope, scientists have developed this simulation of the head-on collision of our Milky Way galaxy and the Andromeda galaxy. Estimated to occur in 4 billion years.

Humans will either be extinct or a completely different species by that time. I bet on extinction.

Both mean the same thing. And neither one is bad. Think about it.

Our Sun will be a Red Giant when that happens so Earth will be inhabitable unless mankind colonized other star systems or galaxies.

[VideoFromSpace]

Actually no. The Sun will still be in its yellow dwarf phase (as it is now) at that time the encounter begins. Moreover: Nothing at all happens to most of the stars in a galaxy collision because the distances between stars is so vast. Much more likely, though, is your point about colonization. The remote descendants of humans (which probably will be nothing at all like us) will have long since colonized many nearby stars...or died trying.

Okay, then, I should have stated the years then. An article in Universe Today states that Sun will reach the Red Giant phase 7.9 Billion Years from now. According to research done by Schroeder & Smith, the Sun will reach 256 times it's original size. The article also states it starts to bloat in 5 Billion years.

Right. So the Sun (and presumably Earth) has 1 Billion years of life ahead of it after the galaxies begin to combine.

omg, everybody panic!

[Lance Taylor]

It will likely be cloudy in Edmonton so we won't see this.

As the flap of the wing of a butterfly in China causing a storm in South America, éverything is cause and effect, connected to the whole.

[Stephen Okawa]

Meh, we'll be fine.

Triangulum Galaxy May be involved in this accident but it's only rumors

4 Bllion Year later

[thorsbomber44442]

Or still on the way.

[AlphaBlob]

I'll still be alive when that happen!

[Murskauh]

That Triangulum galaxy is a coward

[satisflymysoul]

question: would the constellations as they're viewed now still be in the samelocations during the collision and after these 2 galaxies combine?
