What is dark matter and what exists for it?
We know that dark matter exists because it got gravity, though it is invisible. It hold galaxy and Universe. There is a theory there many other parallel universe outside our universe and dark matter holds those universe up and some scientists says that dark matter are just mass of the matter of the parallel universe. It sounds crazy but that is the Law of Physics. However there is not exact explanation of what dark matter really is, so there are still Noble Prices for those who can come up with a reasonable explanation
Is it true dark matter cannot be seen?
Yes this is true. We have recently discovered dark matter exists with the help of the Hadron particle collider, but can not see dark matter. (not yet any way)
What had Astronomers have been unable to prove that it exists?
'Dark matter' and 'dark energy' have not been observed or proven yet.
What are some unique info?
What exists at the center of a black hole. Why is dark matter unaffected by photons. What is dark energy. Examples...
Does dark matter possess any mass and energy?
Yes, dark matter has a lot of mass. It makes up about 20% of the universe (much more than regular matter). Since it has mass, it also has energy. In fact, dark matter's mass is the main reason we even know it exists. Astrophysicists can observe its gravitational effects, though it is extremely hard to detect in any other way.
Is dark matter a reality or made up becauseof the lack of matter in the univrse?
There is a lack of OBSERVED matter, but it is quite clear (due to gravitational effects), that dark matter indeed exists. There are all kinds of pieces of evidence in favor of dark matter. It isn't known yet what it is made of.
Why can't the so called dark matter be directly observed?
We know that dark matter exists because it got gravity, though it is invisible. It hold galaxy and Universes. There is a theory there many other parallel universe outside our universe and dark matter holds those universe up and some scientists says that dark matter are just mass of the matter of the parallel universe. It sounds crazy but that is the Law of Physics. However there is not exact explanation of what dark matter really is, so there are still Noble Prices for those who can come up with a reasonable explanation.
How many people believe dark matter exists?
Dark Matter is required to exist because without it all galaxies would fly apart. In our Milky Way Galaxy Dark Matter accounts for 90% of the entire mass of the galaxy. Dark Matter is simply that, Dark. As it cannot be seen and has a very weak force. It only interacts with gravity.
What is the connection between gravity and dark matter?
When the total amount of mass in a galaxy is computed, and the total amount of gravity is calculated there is a discrepancy. There appears to be more matter in the galaxy than what can be observed. Dark matter was theorized as being matter that exists but does not interact with electromagnetic radiation. Because of this, it cannot be seen. That is why it is called dark matter.
What could be the possible exists between galaxies?
Dust, gas, dark matter, perhaps individual stars and planets.
Matter does not contain?
Matter is the basis for everything. Anything that exists has matter. Dark matter are anomalies that cannot account for "missing matter". Matter does not contain the solar energy and radio signals that travel through "empty space".
Is dark matter Solid liquid or gas?
We do not know as we have not found any dark matter to examine. The only way we detect it and know it exists is due to its gravitational attraction of the ordinary matter we can see. One speculation when neutrinos were discovered to have tiny nonzero masses was that dark matter might be neutrinos. Another speculation is that dark matter is only ordinary matter, but its in another separate universe in a shared higher dimensional spacetime. Nobody knows.
