A much more massive variety of neutrino.
Dark matter's strength is proportional to it's mass. This means that more dark matter in one spot is stronger then a little bit of dark matter in that same spot.
The simplest answer is: Everything does. One possible definition of 'Universe' is: All of time and space and everything in them.
Not only have we no shred of an answer to that one presently,we're not likely to ever have one in the future.Another view: Dark matter permeates our universe, interacting only very weakly with ordinary matter. It was produced, presumably, at the big bang event and only interacts with us through the gravitational force. God, if He exists, has very little indeed in common with dark matter.
No, dark matter is entirely different from antimatter. For one, we know a lot about antimatter and have been able to do experiments with it and actually utilize it in some nuclear reactions. Dark matter is a theory to help understand why the universe does not behaive the way we believed it should. Galaxies are showing that they do not have enough mass to have the gravitational effects that they do, so there must be matter somewhere, this is labeled as dark matter.
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.
The only particle that we have observed that may be a candidate are neutrinos. Several experiments are being conducted at the southern polar ice cap to see if this is a possibility or not.

The axion is an hypothetical particle, which has never been detected. It was born as an elegant solution to the problem of CP in strong interactions and is one of the candidates for dark matter.

The worst film in any category will be a matter of personal opinion. While many people may agree on one candidate, no candidate will be the choice of everyone.
The dark matter one can see in the brain is known as glial cells. It is now thought that one type of the glial cells, the astrocyte may be involved in information processing.
No, it is invisible, however it got gravity. No one actually come up with a theory that explain what dark matter really do, so there is still a Noble Price waiting for people to come up with a explanation 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.
