How can astronomaers detect dark matter if the cannot observe it correctly?
say my name say my name
Why do astronomers theorize that most of the matter in galaxies and clusters of galaxies is dark matter?
most of the mass in a cluster of galaxies is invisible, which provides astronomers with the strongest evidence that the universe contains a great amount of DARK MATTER

Why do astronomers think there is dark matter in the universe?
That is because the dark matter attracts normal matter through its gravitation.
What the entire universe called?
The universe is the term used to describe all of space, time, matter, and energy that exists. It includes planets, stars, galaxies, and everything that we can observe or detect through scientific methods.
Why do astronomers study the sun?
There is an very dangerous matter in the sun named Black Matter. If the astronomers can get some of that matter, they can let a rocket fly to Jupiter and the austronauts will survive. Excuse me if my English is bad, I'm Dutch.:D
How do atronomers detect dark matter?
Gravity. We cannot see or directly detect "dark matter", and the only reason why astronomers talk about "dark matter" is that galaxies like the Milky Way appear to be spinning too fast for gravity to hold them together. Or at least, for the gravity of the mass that we can SEE to hold them together. Gravity comes from matter, and we can't see enough matter, so it must be "dark matter". This may be in the form of trillions of invisibly-dim brown dwarf stars, or in black holes from which no light ever escapes - or it may be something entirely new. "Dark matter" is the something new.
Is normal matter the opposite of dark matter?
no actually matter is well matter that we can detect but dark matter is there just we can't detect it but we do no it's there because everything is either matter or engery but we can dectect engery so it's darkmatter
What's the dark matter in the universe?
Dark matter is matter of an unknown type. It is known to exist, due to its gravitational influence, but it is not known what it is made of. There is at least 5 times as much dark matter than "normal" matter.
What could it be like if we don't have matter?
Nothing. If there were no matter, then there would be no humans to observe the 'no matter' state.
How can astronomers detect where black holes are if no form of radiation can ever get out of a black hole?
There are two ways of detecting black holes indirectly. First, it is possible to observe the effects of a black hole's gravity on nearby objects. Second, while no radiation can come from within a black hole's event horizon, mater that has not yet crossed can still be seen. If a large amount of matter is falling toward a black hole, then it can become superheated and emit intense x-rays.
Are there many solar systems within a galaxy?
Oh, very likely, but astronomers are only just beginning to detect them. Whether any contain planets that may support some sort of life is another matter. There is no reason to think not but we may never know for certain.
