Is the universe/galaxies all on a general plane?

[TurtleCrusher]

As in, is the arrangement on a general X-axis like this? Or is it expanding and laid out in a spherical shape?

Just curious...

All spiral galaxies are not the same.

LAst year or was in 2013 a few astronomy people found a galaxy where they discovered a sun that had over 300 planets were circling around it from all directions and I think a few were trying to track how these planets were not hitting each other.


You need to watch more CARL SAGAN videos to see how many different shapes there are. Some are even bent and look like a floppy pancake because of gravitational pull from a nearby galaxy tugging on it.

Conservation of angular momentum.

The shape of the universe is still a matter of debate.

You got a link to this? Interesting...

Galaxies and solar systems are disc shaped due to conservation of angular momentum. Solar systems can be aligned in any random direction relative to each other, and other galaxies can be aligned in any random direction relative to the milky way. There is no preferred orientation to the universe, only relative to other objects.

the fact that we can see spiral galaxies proves that they are not in the same plane. if all galaxies were in the same plane all galaxies would look like a line with a bump in the middle

Not really. We see them mostly by looking up or down our axis of spin. They can spin on the same axis and still not appear that way. However looking at NASA photo, galaxies appear to be at all sorts of different axis anyways.

If all galaxies were in the same plane - not simply oriented the same way, but also having the same z coordinate - we wouldn't see any galaxies when looking outside of the plane of our galaxy.
