The question of what lies at the center of the universe is still a topic of scientific investigation and debate. Our current understanding of the universe suggests that it does not have a specific center in the same way that objects like galaxies or solar systems do.
According to the prevailing cosmological theory, the Big Bang, the universe originated from a highly dense and hot state about 13.8 billion years ago. As the universe expanded, matter and energy spread out uniformly on a large scale, resulting in a homogeneous and isotropic distribution of matter on the largest observable scales. This means that, on a large scale, the universe appears to be roughly the same in all directions, with no privileged center.
It's important to note that the concept of the center of the universe can be misleading, as it implies a particular point or location within space. However, according to our current understanding, the expansion of the universe does not occur from a central point outward, but rather, it expands uniformly in all directions.
Therefore, while a supermassive black hole may exist at the center of our galaxy, there is no identified specific center of the universe as a whole. The universe appears to be expanding and evolving on a cosmic scale without a well-defined center point.
