gravitational force on fluid(cosmological situation) simulation

[@Darkrenheit]

The fact that it shaped like a Galaxy explains a lot

[@Ionee-q4f]

its shaped like a galaxy, but you may be surprised to hear that its not actually acting like one. In this simulation the arms that resemble those in spiral galaxies appear to have particles that move with the arms, but this isn't the case in spiral galaxies where stars move in and out of arms throughout their orbits. The arms in spiral galaxies are more like waves, regions where lots of stars and gas and stuff get close together before spreading out again.

How can it not? Its simulated in 2d space. More interesting question is why do galaxies flatten out

[@Ionee-q4f]

@@Rich-je9fy they form flat because they are spinning. As the galaxy ages the gas it formed from is turned into long lived stars which interact with each other and get flung in directions often not in plane with the galaxy, eventually the mostly neat disk disperses into a hazy cloud of stars and very thin dust

a 5 second ad for a 10 second video? smh youtube

I got an ad in the middle of the video😐😐😐

Krill issue. I didnt get one(no adblocker)

​@randomhi848 i said krill on purpose lmao, its a joke

[@iheartlreoy8134]

So, we are fluid ?

[@KirstenTheSpaceGirl]

No

[@iheartlreoy8134]

@@KirstenTheSpaceGirl then why does the fluid form like a galaxy

[@KirstenTheSpaceGirl]

@iheartlreoy8134 It's coincidental. Galaxies are not fluid lol. They sre mostly made up of stars and dark matter

[@iheartlreoy8134]

@@KirstenTheSpaceGirl i understand but maybe matter is kind of fluid in itself

[@KirstenTheSpaceGirl]

@@iheartlreoy8134 It might seem that way on larger scales but it's not actually fluid.
