In my mind, there is no question that they're out there. My Career is well established. My texts books are required reading in all the major capitals on planet earth. If you want to become a physist to learn about the unified feild therory-you read my books. Therefore, I'm in a position to say: Yes- Most likely they're out their, perhaps even visited, perhaps on our moon.
Michio KakuI often think that we are like the carp swimming contentedly in that pond. We live out our lives in our own "pond," confident that our universe consists of only the familiar and the visible. We smugly refuse to admit that parallel universes or dimensions can exist next to ours, just beyond our grasp. If our scientists invent concepts like forces, it is only because they cannot visualize the invisible vibrations that fill the empty space around us. Some scientists sneer at the mention of higher dimensions because they cannot be conveniently measured in the laboratory.

Michio KakuIt's risky to allow radiation to constantly go up into the atmosphere. The main criticism of this approach of entombing it is that it would cost too much, involve too many resources and people. But think of the cost of having all the crops impounded by the government, all the milk being thrown into the river, people's livelihoods destroyed.
