The question of whether the universe is infinite or finite is still a topic of scientific investigation and debate. the true nature of the universe's size and whether it is finite or infinite remains uncertain.
One possibility is that the universe is infinite in size, meaning it has no boundary or edge and extends forever in all directions. Another possibility is that the universe is finite but unbounded, similar to the surface of a sphere. In this case, the universe would have a finite volume, but if you were to travel in any direction long enough, you would eventually return to your starting point.
Scientists have gathered substantial evidence suggesting that the universe is very large, possibly even infinite, based on observations such as the distribution of galaxies and the overall geometry of space. However, due to the vastness of the universe and the limitations of our current technology and observational capabilities, we cannot definitively determine its true extent.
It's important to note that the term "infinite" is often used to describe the universe because we currently have no observational evidence of a boundary or an end to it. It is possible that our inability to find anything beyond the observable universe contributes to the notion of it being infinite, but this is still an area of ongoing scientific inquiry.
