How the Edge of Our Galaxy Defies Known Physics

Here is my theory that will one day be proven 100% (by someone else lol)  If normal matter exists in normal physics then dark matter must exist in the dark physics - not a separate dimension - it exists in the same reality it just does not interact with any known matter including light apparently.  However, gravity is universal constant, so even if it does not interact, it still has mass and still counts for gravity.  I will bet anything the key to finding dark matter is gravity.  If you can apply enough gravity you could possibly condense dark matter to something we can detect since gravity has physics changing properties - for all we know dark matter is hiding in a time out of sync from ours that's why we cant detect it.  Gravity could possibly even fix the time distortion allowing us to perceive it. Kinda like adding pressure to some gasses to make them liquid or a high speed camera slow things down so we can see it.  One day this post will be in a museum just saying.
