Proof for hyperbolic universe?
we heard that universe is elliptical
In Elliptic space, every light ray is a geodesic line. Light rays will be circling the geodesic line forever unless blocked by some object. We can see the same light ray of star many times, because the light ray circles in the space forever. Also, we can see the same star from opposite directions many times, because the light ray from other side of star circles in the space forever too. Since the Universe was at least many billions old. All the lights of the sun and stars had collected so many billions of years. The Universe should be so bright even at nighttime. Of course that is not the case. So the possibility of the Universe is only Hyperbolic Universe.
