Answer 1

Hi..

1)As the universe expanded, the initial angular momentum would be spread among the bits of matter that we call galaxies, so that the galaxies now tend to spin in a preferred direction. If galaxies tend to spin in a certain direction, it means that the overall universe should have a rather large net angular momentum.

2)This is due to the Surface Tension. When our Universe was hot enough (after Big Bang), the planets were in in the shape of liquids and they had great attraction towards each other and hence they're round because the surface tension in spheres is the least.

3) think that universe is elliptical in shape..


Hope this helps u!
