Physicist (cosmologist) Sean Carroll, a darling of the popular-science press, is a vocal atheist. Although he does not believe in the existence of God, because it’s an untestable theory, he does believe in the Many Wor(l)ds Interpretation of quantum mechanics (MWI), another untestable theory. In a recent blog post, Sean pities those who do not believe in the true interpretation, for they shall not see the glory of heaven. According to Sean, MWI is easily derivable, using only pure logic, from a few, very simple, widely accepted axioms. Sean has devoted considerable time and effort to proving the existence of many worlds and disproving the existence of God.
I’m afraid I’m one of those nonbelievers that Sean pities so much. See my opinion of MWI here.
Although I don’t believe in MWI, I do have a scientific religion, quantum computation. There is a big difference between QC and MWI, though. Quantum computation is a testable theory. Even better, its ultimate goal is to construct a tangible, physical machine. That machine is a God to me, a Deus ex Machina. I believe that this God/machine will descend from heaven (thanks to a handy crane) at the end of the play, and save the day, just in the nick of time, when the situation seemed all but hopeless.
