No, it most emphatically does NOT suggest that to a physicist. The name "big bang" is a derisory term coined by Fred Hoyle to describe a theory of the universe that he disagreed with, but which was (and is) correct anyway. The "point" interpretation is strictly pop-sci, not science.RandyD123 said:The "big bang" suggests that everything came from a single point.

The concept of the universe having no center is based on the idea that the Big Bang occurred everywhere at once, rather than at a specific point in space. This means that the universe has been expanding and evolving uniformly in all directions, without a central point of origin. Therefore, the universe does not have a physical center, but rather extends infinitely in all directions.
One of the main pieces of evidence for an infinite universe is the observed cosmic microwave background radiation, which is a remnant of the Big Bang. This radiation is evenly distributed throughout the universe, suggesting that the universe is uniform and infinite in all directions. Additionally, the ongoing expansion of the universe also supports the idea of an infinite universe.
While the concept of an infinite universe suggests that there could be an infinite number of galaxies, we are currently unable to confirm this. Our observable universe is limited by the speed of light and our technological capabilities, so we are only able to observe a portion of the universe. It is possible that there are more galaxies beyond our observable universe, but we cannot definitively say if they are infinite or not.
An infinite universe means that the universe has always existed and will continue to exist indefinitely. This challenges our understanding of time and space, as the concept of a beginning or end becomes irrelevant in an infinite universe. Additionally, the idea of an infinite universe also suggests that there could be other universes beyond our own, further complicating our understanding of time and space.
Yes, there are alternative theories to an infinite universe, such as the idea of a finite and bounded universe. Some scientists propose that the universe could be shaped like a three-dimensional sphere, with no edges or boundaries, but still limited in size. However, this theory is still being debated and there is currently no conclusive evidence to support it.
