It’s admittedly non intuitive, but no there’s no difference. The reason is that space isn’t expanding into something else, but rather space time itself is stretching. Which reduces the energy density, which cools things down. In exactly the same way whether the universe is finite or infinite.
- naveen99 5y agoI mean a theoretical universe without this space time expansion. Could it not be compatible with distant objects moving further away without space time expansion ? Besides what time is spacetime expanding over ?
- garmaine 5y agoIt’s not expanding over anything. Expansion is an intrinsic property.
