Eli5 Why are galaxies flat instead of being spherical like stars and planets?
In: 22
All galaxies are formed around a black hole, everything orbits this or leaves the galaxy one way or another.
The funny thing about black holes is they spin, and also create a current around themselves that other things also spin in. This force means that objects above or below their axes either join in the spinning or again are removed from the galaxy one way or another
Elliptical galaxies are the closest to ‘spherical’, they are kind of squished a bit, and there is plenty of those around it seems.
