>>>>LOOKS AROUND EVASIVELY<<<<

Sorry, I think I might have something to do with that. Sorry about that. I'll fix it before they collide. Promise I will, I'll get around to it.

I'm gonna go out on a limb and say gravity.

Very cool pics though.

After watching galaxies collide, I don't believe in aliens. Just distant neighbors with an incompatible cellphone provider.

I dunno, if they're 10 million light years apart, they're not even close to colliding.  In which case, the distortion of one has nothing to do with the other.

By the time they collide the dark energy expansion of the universe will have ripped them all apart.

Well glad we sorted that all out, now if you don't mind me, I've got to organize the Union Galactic 447 Dark Energy Strike. We's gonna be on strike for at least 300 millennia , but yous don't worry we won't start for another 3 millennia.

/ Good luck on that dark energy expansion project, w/o us dark energy; huh huh huh.
// I mean really who are you gonna call, some gravity scabs, you make me laugh.

Has anyone called Geico? Seems like this is something we need insurance for.

In fact, I think I may start my own company specializing in galaxy collision. The premiums are an easy $78 dollars a month. And if you get hit by another galaxy, or if you hit another galaxy, you get paid $10,000 dollars.
So who wants to sign up?

Maybe the camera was physically moving back. Did you even consider that?

These must be the galaxies from the end of the Empire Strikes Back, they were moving pretty snappily around.

You mean dolly out?  I considered it, but choose not to list every possible camera move.

Besides in this case "dolly out" would mean moving the camera thousands of light years.

There was an article recently about how dark energy might not exist; it might just be an artifact of some sloppy math. Keep in mind, that sort of explanation doesn't work for dark matter, because dark matter seems to vary a lot from place to place, which is why it's called "matter".

Nah, they were using gravitational lensing.  They only had to move Oprah across the room.

Gravity.  That is the reason why.

Because if all galaxies are expanding away from each other due to expansion, why are some of them moving towards or past each other instead? Is it a fluke of chance, part of the underlying structure of the universe?

Well, because they are all not moving away from each other.  Galaxies are evolving and moving and splitting and effected by each other's activity going back billions of years.

Most are moving apart, sure.  But many are not.  Case in point...  The Andromeda galaxy is headed this way.  How could that be if all the galaxies are racing apart?

I think it's safer to say that much of the science on how galaxies are evolving is still very new.  There is still a lot to learn.

When it comes to the expansion of the Universe, it's easier to think of it this way: The galaxies aren't moving at all. Rather the space between them is filling up with more space. Think of it like raisins in a rising loaf of bread or dots on an expanding balloon.

The more space that exists between the galaxies, the faster they are growing away from each other. Or at least that's what we observe.

Now, some galaxies may be close enough together that the attraction of gravity is greater than the expansion of space, and that is what we see. On a small, local scale, the expansion of the Universe is meaningless, just like at the subatomic scale gravity is meaningless (electromagnetism and the nuclear forces are stronger).

The Universe tends to behave differently depending on the resolution, governed by different forces which obey different laws of physics.

But that's just my layman's conjecture.

Amoungst our galaxies are such diverse elements as stars, planets, quasars...

durbnpoisn: The Andromeda galaxy is headed this way. How could that be if all the galaxies are racing apart?


They aren't technically racing apart. But the scale we are talking about when looking at the expansion of the universe is in the order of billions of lightyears. M31 is only 2 million lightyears away, which is like a drive to the end of the block in space terms. It's very close.

In other words: At this scale the gravitational force between Andromeda and The Milky Way is stronger than the expansion of the space between them.

Here's a handy scale for reference:

Everything in the Local Galactic Group and smaller is dominated by gravity. They are actually coming closer together or are held in orbital resonance with one another.

What cosmologists have noticed is that galactic clusters neighboring the Virgo Supercluster (and even some distant galactic groups within the supercluster) are pulling away due to the expansion of space between them. And moreover, the further away a galactic supercluster is, the faster it seems to be receding.

But even more interestingly: The rate of this expansion of space between the superclusters seems to be accelerating.

Sounds like  altering the focal length; I'd still call it zoom.
