It is worth noting that there is, as yet, no way to know whether the possible collision is definitely going to happen or not. The radial velocity of the Andromeda galaxy with respect to the Milky Way can be measured by examining the Doppler shift of spectral lines from stars in the galaxy, but the transverse velocity (or “proper motion”) cannot be directly measured. Thus, while it is known that the Andromeda galaxy is getting closer to the Milky Way by about 120 km/sec, there is no way to …

Also, just discovered a few months ago, the Milkyway is actually BIGGER than the Andromeda.
he thinks his cool. he thinks it some sort of termintor that finished and excited mission with lots of explostion. but what we all what he reali finshed.
Where is this simulation from? How was it made? It is beautiful to watch!
Why in the beginning of the title is written “Mission Accomplished”?
What did you use for this simulation?
Well seeing that most stars are light years apart what would be the chance of two stars colliding during the mixing? About a billion to one? So even if Andromeda collided with the Milky Way there would be nothing to worry about. According to astronomers there are stars in the Milky Way that orbit the core opposite to other stars, plus bands of stars that orbit at different velocities. This suggests the mixing of galaxies has happened once before in the Milky Way. Check out the inflation theory.
Any other background song would have been better!!!!
i wonder what will happend to da human race
That is our sun.
What did you use for this simulation.
Dont worry about me Ill be dead when this happens
What’s that large object that’s circling close to the centre?
The sun will be around for another 5 billion years at least. Probably more.
r u dumb…3 billlion yrs from now…the sun would already b gone by then
Excellent!!!
****, and its on its way here, we gotta find technology to escape from our galaxy sooner
Even when they do collide it’ll just become a bigger elliptical or irregular galaxy. Anyway, the sun is going to swell up well past the orbit of mars in approx. 5,000,000 and take most of the solar system with it, including Earth
What is that program?
I thot the collision will produce an elliptical galaxy. I don’t really see elliptical-ness coming about here, perhaps because the simulation lacks dust and gas simulation?
