发帖数: 17 | 1 Q: 银河系到另外一个星系之间都有什么？空的？有恒星吗？
There are just my guess, don't take it seriously:
1. Mirror sites: galaxy after galaxy
2. Cyclic composition: like the surface of the earth
3. Singular point/boundary: there is a sudden boundary space where no material
exists
4. Infinite universe: endless
5. Finite yet expanding universe: as Einstein proposed
6. Infinite yet limited universe: as Hokins proposed | t********r
