A physicist (with a cool name) provides an update on ideas proposed some years ago by Eugene Wigner in “The Unreasonable Effectiveness of Mathematics in the Natural Sciences“:
Max Tegmark has a theory about reality. According to Max, who is a cosmologist and professor of physics at MIT, all that exists, all this familiar stuff—that ergonomic chair you are sitting on, your body and your brain, even the space surrounding you— is math and we are merely “self-aware parts of a giant mathematical object.”
Here is a 4-minute snippet featuring Tegmark from a BBC program. Tegmark acknowledges that, if his theory is wrong, then physics will hit a “roadblock” upon which it will not ever be able to get past. (I believe the ‘New Mysterian’ notion of cognitive closure is just such a roadblock.)
