The diameter of the universe is not precisely known, and it’s a topic of ongoing scientific research and debate. The observable universe, which is the part of the universe that we can currently see and study, is estimated to be about 93 billion light-years in diameter.
It’s important to note that the universe may be much larger than the observable universe, but due to the finite speed of light and the expansion of the universe, we can only see a portion of it.
Keep in mind that these numbers are based on current scientific understanding as of my last knowledge update in January 2022. New discoveries and research may have provided updated estimates since then.
