That's quite clearly Alderaan, and this is evidence of the war crimes committed by Tarkin and the Empire!

This pic has stars in the background but the othwr ones iv seen dont... Why is that???

Pretty sure those are all galaxies.

colliding or merging. maybe they really love each other and are joining together is cosmic matrimony.

Here is a computer simulation of the Milky Way and Andromeda galaxies, in about 3.75 bn. years - https://www.youtube.com/watch?v=-WoLSL3EDEs

Then this will make your day - Scientists say with the immense space between stars, the odds are that our solar system will go untouched.

You can actually see the remnants of a collision between the Milky Way and a another smaller galaxy from like 8 billion years ago around us.

I think you mean 6000 years ago.

Were actually on a collision course with the Andromeda galaxy if I remember correctly. But wont happen for several billion more years.

Yep yep. We will form the "Milkdromeda" galaxy.

How do things collide when they are moving apart in the expanding of the universe?

9 years ago | Likes 11 Dislikes 2

Space time is also moving. And likely nothing but the massive black holes at the center will touch. So much room between stars

9 years ago | Likes 1 Dislikes 0

Wow I never thought of it that way. And also trying to comprehend the speed of this seemingly slow motion impact

9 years ago | Likes 7 Dislikes 0

How do we move around at all then?

9 years ago | Likes 1 Dislikes 0

Moving apart on the grand scale. Things can still hit in their own local regions

Especially when you have the immense gravity of galaxies in play.

Gravity mostly

We're actually mid-collision right now, in case you're wondering. Give it another 4 billion and we're colliding with Andromeda, too.

Now are we gonna merge or will we simply collide and whats left moves on?

9 years ago | Likes 1 Dislikes 0

We collide, kinda move past, gravity pulls us back, collide, and repeat until eventually we merge into one galaxy.

Though in reality, it's highly unlikely that Earth will collide with any planets when that happens. We'll be dead from other things, though.

Am I mistaken in having heard that there is so much space between stars that when galaxies collide there isn't really much actual collision?

Colliding dust and gas will set in motion a burst in new star formation.

9 years ago | Likes 1 Dislikes 0

Nah man, you're not, chance of even a single collision is insanely small. Imagine shooting 2 basketballs, one from ny, other from la /1

9 years ago | Likes 1 Dislikes 0

and expect them to collide in the middle

9 years ago | Likes 1 Dislikes 0

Nope, you're right. Mostly an interaction of gravitational forces, and not much else.

9 years ago | Likes 21 Dislikes 0

So, if life still exists then, would the collision kill us all, or would it just be pretty lights in the sky for a billion years?

9 years ago | Likes 6 Dislikes 0

Here's a pretty thorough explanation: https://www.youtube.com/watch?v=7uiv6tKtoKg

9 years ago | Likes 5 Dislikes 0

Basically, pretty lights, but we'll be dead. Oceans dried up, an atmosphere like Venus, a couple billion years later... Yeah, we ded.
