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
What else can I help you with?
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...
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.
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 does most matter in the universe exist in?
Most matter in the universe exists in the form of dark matter and dark energy, which are currently not fully understood by scientists. These two components make up the majority of the universe's mass-energy content, with ordinary matter (protons, neutrons, electrons) making up only a small percentage.
Could you walk through a wall made up of dark matter?
Dark matter is a mysterious substance that does not interact with regular matter, so it is unlikely you would be able to walk through a wall made of dark matter. Our current understanding of dark matter is that it exists in a halo around galaxies and does not clump together like regular matter to form solid structures like walls.
What could be the possible exists between galaxies?
Dust, gas, dark matter, perhaps individual stars and planets.
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.
Assuming dark matter exists is it black holes or in black holes?
Neither, dark matter is an undetectable yet massive existence within our universe. It is spread out relatively smoothly, not bunching up in particular locations. For more information, search dark matter images (computer simulated), they help the visualization of it.
What is the opposite of Dark Energy?
There is no opposite of dark energy in the sense that there exists something that is the exact opposite of dark energy. Dark energy speeds the rate of expansion of space, even empty space, and gravity, mass, or matter causes the opposite in that it causes a decrease in the rate of expansion of space in areas that have matter.
Can dark matter kill you?
The whole point of dark matter ... the thing that makes it "dark" ... is that it doesn't interact with normal matter except through the gravitational force (and, possibly, for some potential types of dark matter ... remember that nobody really knows what it actually is yet ... the weak force).One type of dark matter that we know about for sure is neutrinos. Around 65 billion neutrinos per second pass through every square centimeter of your body perpendicular to the direction of the Sun. They have been since you were born ... since before you were born, in fact. Even at night, because they go straight through the Earth too and come up through the ground on the side facing away from the Sun. The kajillion that have already done so haven't killed you yet, it's not all that likely that the kajillion and first is going to kill you.About the only reasonably possible way to die from dark matter would be if there were a lot of it concentrated in one smallish area, in which case you could be pulled apart by tidal forces if you were in a spaceship that went too close to it. This also isn't likely to happen.
