Dark matter

Post by osmium2 »

Hi guys :D

I need help with these questions.
Is dark matter has a mass ?
Is it cold or hot inside the dark matter ?
can one say that dark matter has the same charasteristic as the normal light ? I mean the speed of the light, velocity, absorption or emission?
thank you guys for your answers :)
