Michio Kaku On Extraterrestrial Life
I don’t think I will live to see communication with extraterrestrials. However I do think it is something that is possible for humanity in the future.
Michio Kaku puts this all so eloquently. This further adds to the idea that we are alone in the universe. Even if there are intelligent beings in space of type 3 or 4 civilizations, why would they want to visit us? The anthill metaphor is a great way to understand this idea.
And if that’s not enough, he goes on to talk about the “multiverse”, which in itself is enough to give you plenty to think about. This is great stuff really!
