As others have said, it's not possible due to microwave background, but more logically, if one universe "ends," that's it. It has all ended. Everything has been crunched up. So there's nothing to see because even if the laws of physics were the same in the previous universe, photons exist in space-time, not out of it. So if all of space-time is crunched up, there can be no more photons and thus nothing to see.
