Interacting Universes: Dark Matter & Gravity

[StavrosPanagiotidis]

I think that dark matter is matter from an other universe that we can only interact with through gravity. Does anyone have a hypothesis for why does the matter interact with us only with gravity and not with any other of the fundamental forces like electromagnetism etc.
Thanks!

Yes, there are many hypotheses. Check out this wikipedia article if you'd like to know what those are. Possibilities include "exotic" matter, unseen normal matter, and modifications to gravity.

Thanks, I will try to stick to mainstream science.
