String Theorist Michio Kaku: ‘Reaching Out To Aliens is a Terrible Idea’
An excerpt from a wide-ranging interview of String theorist Michio Kaku in which he talks about Newton finding inspiration amid the great plague, how the multiverse can unite religions, and why a ‘theory of everything’ is within our grasp: The Guardian: You believe that within a century we will make contact with an alien civilisation. Are you worried about what they may entail?
Kaku: Soon we’ll have the Webb telescope up in orbit and we’ll have thousands of planets to look at, and that’s why I think the chances are quite high that we may make contact with an alien civilisation. There are some colleagues of mine that believe we should reach out to them. I think that’s a terrible idea. We all know what happened to Montezuma when he met Cortes in Mexico so many hundreds of years ago. Now, personally, I think that aliens out there would be friendly but we can’t gamble on it. So I think we will make contact but we should do it very carefully.

The Guardian How close do you believe science is to accomplishing a theory of everything?
Kaku: Well, I think we actually have the theory but not in its final form. It hasn’t been tested yet and Nobel prize winners have taken opposite points of view concerning something called string theory. I’m the co-founder of string field theory, which is one of the main branches of string theory, so I have some “skin in the game.” I try to be fair and balanced. I think we’re on the verge of a new era. New experiments are being done to detect deviations from the Standard Model. Plus, we have the mystery of dark matter. Any of these unexplored areas could give a clue as to the theory of everything.
