Theoretical physicist and futurist Michio Kaku is well-known for his contributions to string theory and his capacity to simplify difficult scientific ideas for the average person. He talked about the shortcomings of conventional theories that explain events after the Big Bang but find it difficult to explain what happened before it in one of his talks about the origins of our universe.

According to Kaku, string theory is the new framework we need to comprehend the mysteries that existed before the Big Bang. Kaku claims that string theory offers intriguing hypotheses regarding the origins of our universe. One such theory is that our universe might have formed as a result of the collision of two other universes. The idea that our universe might have "sprung" from another, leaving behind a trace—a cosmic umbilical cord, if you will—is another idea from this theory.

According to science, this umbilical cord that ties our universe to its parent or nearby universes is called a wormhole. Imagine it as a space-time tunnel connecting various parts of the universe, analogous to the umbilical cord connecting a developing baby to its mother.

In addition to providing insight into the universe's beginnings, Kaku's explanation creates new opportunities for investigating the nature of reality beyond our current understanding. He is a significant voice in popular science communication because of his theories and work, which attempt to close the gap between difficult physics ideas and common knowledge.
