Michio Kaku joined us in an online chat today. The chat transcript is below. In science fiction, a great distinction is made between the two, but from a mathematical point of view, they are the same. So, mathematically speaking, they are the same. This could be true.
Most scientists giggle when they hear about UFOs, because the distance between stars is so great.
It would take centuries, to millennia, for a civilization to navigate, even to nearby stars. However, if we have what is called a type-three civilization, their energy consumption is so great that they might be able to open up higher dimensions. If we can access the Planck energy, space and time becomes unstable, and wormholes begin to open up, giving us the possibility that we might use these wormholes for transportation to the stars. You say in your interview on this WebShow that ours is likely not a very advanced civilization, that we are a Stage zero civilization. They control the weather, earthquakes, volcanoes, and the ocean.
