hello
I have a question about dark matter
*dark matter would be matter with a mass (and gravity)but it is said it doesn't affect light
the problem I have is that
*black holes( or anything with an huge mass) are told to have sutch an inmense gravity that even light woudn't be able to escape from it
if both of these statements are right how is it possible that dark matter would not affect light and it has gravity
thanks
