Was a black hole the starting point of the universe?

Answer 1

It is possible.

Since we live inside the big bang, we can't know for sure, but it's possible that a black hole created the universe; perhaps it sucked in so much energy and matter that it eventually exploded.

No, the universe did not begin with a black hole. The general consensus in science is that the universe started with the Big Bang, a cosmological event that occurred about 13.8 billion years ago. The Big Bang theory explains how space and time rapidly expanded from a hot and dense state to form all matter and energy in the universe. Although massive stars can collapse to form black holes, black holes are not thought to be the origin of the universe.
