Would the existence of dark matter interfere with the collision of galaxies?

>> No.4526655

depends what you mean by interfere.

>> No.4526659

Do you understand what dark matter is and that its considered a real form of matter?

>> No.4526690

>>4526655
Interfering in that the repelling gravitic force would cause collisions to not go quite as predicted.
>>4526659
It is matter with negative mass, and negative mass causes them to induce a repelling gravitational force on normal matter, and since mass = momentum = energy, zero mass would mean no energy emitted, and negative mass means that dark matter is somehow absorptive or noninteractive with energy as we understand it.

>>4526690
Dark matter does not have negative mass.
It does not repel gravitationally.
> mass = momentum = energy
This is not true

high school has lied to me?

We don't really know since our current models for dark matter behavior are not very refined, but it's an interesting assumption and may yield a good research.

>repelling gravitic force
thats dark energy

and the rest of your post is just nonsense.

>> No.4526759

>>4526740
Dark energy isn't really a force.

>> No.4526768

not in a big way, but check out images of the Bullet Cluster for some interesting dark-matter-and-colliding-galaxies science

where did i say it is?
