PeterDonis replied to the thread Graduate How valid is the Block Universe theory?.What's your definition of "looks official"? No, it's because what we directly perceive is our past light cone, not "now". For example... -

Like.
It's an interpretation, so not testable as far as we know. It's far and away the most popular interpretation, and fits well with the... -
PeterDonis replied to the thread Graduate How valid is the Block Universe theory?.@DarkloidNeos the article you reference, unfortunately, is not just presenting the speculations or opinions of various physicists it... -

PeterDonis replied to the thread Undergrad Help Understanding the Hubble Constant's Units.I'm not sure what the issue or apparent paradox is here. Can you elaborate? Nobody thinks it is. Our current standard model of the... -

Haha.
I am sure the wavefunction is not real but complex-valued :oldbiggrin: -
PeterDonis replied to the thread Is A.I. more than the sum of its parts?.Historically, there have been legal systems that worked very differently from ours. David Friedman has a book about them--drafts of each... -

PeterDonis replied to the thread Graduate Exploring Implicit Assumptions and Foundations of Quantum Mechanics.Um, what? If you have a reference, you shouldn't have to "prepare" an answer. You should just post a link to the reference (textbook or... -
PeterDonis replied to the thread Is the quantum wave function a real object or a mathematical tool?.Yes, there are certain interpretations of QM which say the wave function is real. But you were making a claim that didn't seem to depend... -
PeterDonis replied to the thread Is the quantum wave function a real object or a mathematical tool?.And we say that to stop ourselves from making claims about what's "real" that aren't justified by the fact that we can use the equations... -
PeterDonis replied to the thread Is the quantum wave function a real object or a mathematical tool?.But that doesn't make every variable in the equation we use to predict the outcome real. So I'm not following your logic here. See above. -
PeterDonis replied to the thread Is the quantum wave function a real object or a mathematical tool?.But that doesn't mean variables used in equations are real. Equations and their variables are mathematical tools we use to make...
