Later measurements of individual
galaxies
confirmed this puzzling result.
There's simply not enough visible stuff in
galaxies
to provide enough gravity to hold them together.
All of the evidence we have says that dark matter is there and it accounts for much of the stuff in those beautiful spiral
galaxies
that fill the heavens.
They're other galaxies, just as vast as our Milky Way home.
If dark energy were anywhere near this strong, then the universe would have been torn apart, stars and
galaxies
could not form, and we would not be here.
There are other planets, other stars, other galaxies, so why not other universes?
But then you recall learning that the Sun moves around the center of the Milky Way galaxy, and the Milky Way moves within the Local Group of galaxies, and the Local Group moves within the Virgo Cluster, and the Virgo Cluster moves within... "How fast are you moving?" is not an easy question.
Distant
galaxies
were moving away from us.
For that brief moment in time, the glow was brighter than all the stars in all the
galaxies
in all of the known Universe.
It was designed to orbit the earth and look far beyond our solar system to seek out the coldest stars and the most luminous
galaxies.
What if instead of just experiencing visiting some reality on Earth, you could surf gravitational waves on the edge of a black hole, or create
galaxies
from scratch, or communicate with each other not using words but using our raw thoughts?
And by everything I mean, of course, me and you, the Earth, the Sun, the 100 billion suns in our galaxy and the 100 billion
galaxies
in the observable universe.
And inside each one of these incredible machines, there are hundreds of billions of tiny particles, dancing and swirling in systems that are more complex than the formation of
galaxies.
And in this image you can see thousands of galaxies, and we know that there must be hundreds of millions, billions of
galaxies
in the entire universe, some like our own and some very different.
Two radio
galaxies.
They're all radio
galaxies.
If we zoom out to the full extent of the survey, you can see I found 300,000 of these radio
galaxies.
We've discovered all of these
galaxies
right back to the very first supermassive black holes.
And when the very first stars and
galaxies
switched on, they ionized that hydrogen.
So we should find tens of millions of
galaxies.
It was like I was floating in the universe among clouds of
galaxies.
But what's floating there today are not just clouds of
galaxies
but also clouds of plastic.
We've seen under the sea, three miles down, or
galaxies
hundreds of billions of years out in the future.
In these galaxies, especially in a spiral galaxy like this, most of the mass of the stars is concentrated in the middle of the galaxy.
And there are thousands of
galaxies
in this cluster.
But these
galaxies
are actually moving at extremely high speeds.
So all of these
galaxies
are moving.
We can measure the speeds of these galaxies, their orbital velocities, and figure out how much mass is in this cluster.
And again, what we find is that there is much more mass there than can be accounted for by the
galaxies
that we see.
Do we see arcs in the sky when we look at, say, a cluster of
galaxies?
