I'm reading a book right now called The Theory of Nothing, by theoretical physicist Russell K. Standish, that makes the claim that black holes may be incubators of new universes.
Anyhoot, in reply to the Gospel of John 1:1, Standish says,
In the beginning there was Nothing, not even a beginning! From out of this Nothing, emerged everything we see around us today.A rather startling claim IMHO. It looks like Professor Kaku might dispute this claim. But I have no details of Kaku's argument....
That is my point exactly. They are theoretical, but all the time folks in those fields will suggest extension hypotheses based upon the basic theory.
Apparently, tachyons are an extension hypothesis of the Kaku's view of string theory. Many comments take his to task for making claims about an unproven 'string theory'.
Others say it the basic theory has no predictive value. My response would be "yet". That's not my saying I support the theory. I'm simply suggesting that sometimes when key pieces of a puzzle are not yet in place, the puzzle looks overwhelming. And it's always possible that the theory is in error.
One of the reasons we still have a lot to learn about the Universe is that the human mind is not capable of imagining Nothing.
