Galaxies in sentence

They're the ones that are embedded in that sea of dark matter that are causing the bending of the light to cause these optical illusions, or mirages, practically, of the background galaxies.
So the streaks that you see, all these streaks, are actually distorted images of galaxies that are much further away.
And also, you can tell by eye, by looking at this, that these arcs are not centered on individual galaxies.
The speed with which galaxies within clusters are orbiting is much too large; it must be embedded in dark matter.
If you could do this, what you would find that with each passing day, each passing year, each passing billions of years, OK, the distance between galaxies is getting greater.
And it's not because galaxies are moving away from each other through space.
So clusters of galaxies will tend to form, because of all this gravitational attraction.
Dark energy, on the other hand, is putting more and more space between the galaxies, makes it, the gravitational attraction between them decrease, and so it impedes the growth of structure.
And we know about the present: scientists’ observations of the movement of galaxies tell us that the universe is expanding at an accelerated rate.
To understand these three scenarios, imagine two objects representing galaxies.
Clusters of galaxies would separate.
The objects within the galaxies– suns, planets, and solar systems would move away from each other, until galaxies dissolved into lonely objects floating separately in the vast space.
If the expansion of the universe continues to accelerate, it will eventually overcome not only the gravitational force – tearing apart galaxies and solar systems– but also the electromagnetic, weak, and strong nuclear forces which hold atoms and nuclei together.
But they have these outsize effects on whole galaxies.
How did the galaxies form?
So there's a couple of thousand galaxies you can see easily with your eye in here.
But there's a lot of other galaxies, and some are nearby, and they're kind of the color of the Sun, and some are further away and they're a little bluer, and so forth.
This is only 1,000 galaxies.
It's a very large number of galaxies.
But when you look at some of these regions like this, you'll see more galaxies than stars, which is kind of a conundrum.
And behind that are some more modern galaxies.
And from them in the time sequence we're going to have to go from these tiny variations to these irregular galaxies and first stars to these more advanced galaxies, and eventually the solar system, and so forth.
And we go through a period of accelerating expansion, and the universe expands and cools until it gets to the point where it becomes transparent, then to the Dark Ages, and then the first stars turn on, and they evolve into galaxies, and then later they get to the more expansive galaxies.
I always think of space-time as being the real substance of space, and the galaxies and the stars just like the foam on the ocean.
So here is the Sloan Digital Sky Survey showing the location of a million galaxies.
They go out and point a telescope at the sky, take a picture, identify what are stars and throw them away, look at the galaxies, estimate how far away they are, and plot them up.
Remember, every spot on here is a galaxy, and you see the galaxies, you know, sort of in our neighborhood, and you sort of see the structure.
There are places where there are no galaxies and there are places where there are thousands of galaxies clumped together, right.
We only have a million galaxies, right?
And when you're in the middle of the galaxies it's hard to see the pattern; it's like being in the middle of life.
