Everything that anyone knows about dark matter is just that it is there and it dose not react with anything it touches, goes near, or anything. But dark matter is present which is how galaxies are given the weight needed to rotate around each other and not fly apart.
But, there is one thing that many people do neglect to look at even though it is right in front of their faces. Does anyone remember that trick where you leave a beer in the freezer for about 15 minuets and take it out, it is not frozen but if you knock it slightly on the bottom of the bottle the molecules will start to freeze from the bottom of the bottle up.
Dark mater is present even though we cant see it so it should be subject to a temperature change in some way shape or form. Now it would take more than a cold room to just freeze dark matter, we would need to find a way to shift the molecules in a way that they start to clump together. The challenge really is how do you touch something that reacts with nothing, well the one thing that dark matter does react with is the same thing that it helps Increase, gravity.
I'm suggesting that if we can get a space and get it could enough and find a way to knock the gravitational force in the room just enough at a split moment , that it could possibly freeze the dark matter. There is no gravity shifting machine that is out there that I know of so I this seems a little impossible. But, there is a way to mimic gravity and that is with positive and negative magnetism. if we can chill a room to the right temperature , and make the walls of the room charged negative and positive charges, that may be able to mimic a gravity shift for a split second just long enough to make dark matter solidify.
Yes this is a long shot and such but it is an idea that I personally have not seen brought up ever about it, what are your thoughts? please be critical.
