" We need a theory that goes before the Big Bang, and that’s String Theory. String Theory says that perhaps two universes collided to create our universe, or maybe our universe is butted from another universe leaving an umbilical cord. Well, that umbilical cord is called a wormhole. "
- Michio Kaku

In simple terms, the quote suggests that String Theory offers a way to think about what happened before the Big Bang by proposing that our universe might have originated from the collision or interaction with another universe. This theory also introduces the concept of a "wormhole," which can be visualized as an umbilical cord connecting our universe to its parent universe, providing a potential pathway for energy and matter exchange.

Delving deeper into the quote’s significance, Michio Kaku is highlighting how String Theory challenges traditional cosmological models by suggesting that universes might not just exist in isolation but could interact with one another. This perspective opens up new avenues for understanding cosmic phenomena such as black holes, wormholes, and even the origins of our universe itself. The idea of a "wormhole" umbilical cord implies that there may be direct physical connections between different universes or regions within them, which could explain certain cosmological mysteries like dark matter and energy.

Michio Kaku is a renowned theoretical physicist known for his work in string theory and his ability to communicate complex scientific ideas to the general public. He has authored several books that aim to make cutting-edge physics accessible and engaging, including "Physics of the Impossible" and "Hyperspace." His contributions extend beyond academia into popular science communication, making him a leading voice in discussions about the future of theoretical physics and its implications for our understanding of the universe.
