see that makes much more sense than just "it's the fabric of the universe".

[jorgepeterbarton]

@brianleehouston with angular momentum pushing objects out starting to be more elliptical. these galaxies are revolving of course, which increases as gravity pulls in with conservation of angular momentum. there is then the mutual gravity of all the objects making it more likely they will conform to the same 90deg plane closer together instead of random places- anything passing near the plane will be drawn to it, where there's more gravity. there are actually many different perspecitves on this.

@brianleehouston

Not all galaxies are disc-shaped. Those that are have an abundance of gas, which can collide with each other. This collision process causes friction, which results in gas blobs obtaining a uniform angular momentum - in other words, gas + friction + central gravitating body (such as the center of a galaxy) ---> disc geometry.

is it just me or does it take these guys about 20 minutes to actually complete a sentence? if this was a real physics lecture, i would ask 99% of my money back for taking 100 minutes to explain 1 minute's worth of information!

This is why i refuse to use gps...lol

[getbuckist]

has this man ever sat down with einstein and discussed physics?

[Tenzinpelha]

@brianleehouston it's the fabric of the universe

[suddenrushsarge]

@brianleehouston I believe the angle of the rotation of super-massive black-holes at the center of galaxies dictates the shape, and angle of the mass around it.

space time is fantastic & amazing

[TheSulphyr]

Space-time is an amazingly elegant concept.
