The shape of space-time could tell us We may never know what lies beyond the boundaries of the observable universe, but the fabric of the cosmos can tell us whether the universe is infinite or not ...

However, the observable universe extends farther than 13.8 billion light-years in every direction because, for all the time space has existed, it’s also been expanding.

The observable universe is 92 billion light-years across and contains about 2 trillion galaxies. Telescopes can only show us the observable universe; we can't see beyond that. The universe's shape ...
