Some say it's infinite and some say it's not. But if it's not, then it has to have a center. So my question is, is the universe infinite or does it have a center?
The answer to this question is still unknown and is a subject of ongoing research and debate among scientists. Some theories suggest that the universe is infinite, while others propose that it may have a finite size.
Scientists use various methods, such as observing the redshift of distant galaxies, to estimate the size of the observable universe. However, since we cannot observe beyond the observable universe, it is impossible to accurately measure the entire universe's size.
According to the current scientific understanding, the universe is expanding at an accelerating rate. This suggests that it may continue to expand forever, but there is no way to know for sure at this time.
Since the universe is currently believed to be infinite, there is no edge or boundary. Therefore, it is not possible to know what is beyond the universe or if there is anything beyond it at all.
While there is no conclusive evidence for an infinite universe, there are several theories and observations that support the idea. These include the uniform distribution of matter in the universe, the lack of curvature in the observable universe, and the lack of a cosmic horizon.
