Other particles don't interact with it except through gravitation.
And so how that dark matter is clumping together is playing a really big role in how these other types of matter are clumping together, particularly in
When we start to think about, well, how are stars getting organized into large enough groupings that we might call them a galaxy, that dark matter plays a really big role in that.
Dark matter is very mysterious in that we know that it's out there.
We have lots of really good evidence for it, but we've also never handled it in the lab.
We don't know what kind of particle it is, whether it's one particle or 15 particles.
Then on top of that, you have dark matter, you have visible matter, and then we have something called dark energy, which you were asking about.
And dark energy is completely different from dark matter.
They have similar names because white male scientists have liked to use the word dark as a container for things they don't understand.
Shocking.
Shocking.
In terms of like the impact on the universe they have, they're completely different.
So dark matter acts just like visible matter gravitationally.
But as far as we can tell, dark energy seems to have a negative pressure.
So it causes the expansion of space time to increase in speed.
So space time is expanding.
Dark energy is causing that expansion to accelerate.
So it's continuously increasing in speed.
So that's like the total opposite of dark matter.
In terms of dark matter, like gravitationally pulls together and dark energy basically does the opposite.
