What are the total dimensions in the universe?

 It is not possible to measure the total dimensions of the universe because the universe is infinite in size. The universe is everything that exists, including all matter and energy, and it has no boundaries or edges. It is impossible to measure something that has no boundaries, so it is not possible to determine the total dimensions of the universe.

The observable universe, which is the part of the universe that we can see and observe, is estimated to be about 93 billion light-years in diameter. However, this is only a tiny fraction of the total size of the universe, as there may be parts of the universe that are beyond our current ability to observe due to the finite speed of light and the expansion of the universe.

In recent years, scientists have developed theories about the structure and evolution of the universe, but much about the universe remains unknown and is the subject of ongoing scientific study.
