An international team of astronomers using the NASA/ESA Hubble Space Telescope has discovered a ghostly ring of dark matter formed long ago during a colossal collision between two galaxy clusters. This is the first time that dark matter has been found with a distribution that differs substantially from the distribution of ordinary matter.

There is way to much ignorance in this video. So do the universe a favor and shut it!

annoying narration …
annoying narration or the most annoying narration. This may be a smart man, but the person who chose him to narrate is not. His delivery actually makes me ill. I don’t know this man and I’m sure he is a nice guy, but please take him off these videos, I’m really nauseous listening to his vocal tone.

how could i site this video to place on a website about astronomy till sometime in april?

could dark matter, …
could dark matter, as we can observe it, serve as similar to the shadow of an adjoining dimension? perhaps we’re a bubble within a bubble?

Very strange …
Very strange contradiction
1
In one hand :
The particles in the Universe are more then antiparticles
/ Baryon asymmetry /
2.
In the other hand:
Dark matter and dark energy in the Universe are more
Question :
Does one hand physical know that
the other hand astrophysical do ?

Well, this is how …
Well, this is how it works;
Light are bent by gravity, and all matter in space has a mass with gravity.
So, if the light can not hit the dark matter
and the dark matter can not absorb it, then
the light goes around it. Like the aerodynamics of airplane wings.

The light reached …
The light reached us 2 billion years ago, and has we see it today, this cluster is 5 billion light years away from us.
We actually see this cluster in the past because the light take 5 billion years to get to us. Insted of saying that this cluster is 7 billion years old and that we see it has if it was 2 billion years old, they just say it’s 5 billions light years away from us and that it occured (from our point of view) 2 billion years old ago.

you are missing the …
you are missing the point. No they can’t see anything, theyve never found anything, but, they have a reasonable expectation that something has to be there because of the way objects behave gravitationally…. its not faith.

the ring we are …
the ring we are seeing is 5 billion years old. the event happened 1-2 billion years before it reached the point that we see now. so the event happened 6-7 billion years ago. but at the point that we can see now, it is only 1-2 billion years old.
