Like.
For the most part, the problem is that string theory and GUTs and other BSM models simply don't make predictions about parameters at... -
Iskandarani replied to the thread A Physical properties of the vacuum in GR vs. QFT.@Demystifier. Thank you, I appreciate the sugestion. If you have a favorite review/textbook section that walks through the hierarchy CED...

Iskandarani replied to the thread A Physical properties of the vacuum in GR vs. QFT.@PeterDonis: That's a very helpful distinction between predicting new phenomena versus calculating existing constants. I understand why...
-
Iskandarani replied to the thread I Understanding the historical shift away from absolute simultaneity.Thank you all for the excellent and challenging responses. I think I have a much clearer picture of the consensus view now. If I can try...

Iskandarani replied to the thread I Understanding the historical shift away from absolute simultaneity.that's a very clear and powerful argument. I understand completely. If the only job of a theory is to describe relativistic kinematics...

Iskandarani replied to the thread A Physical properties of the vacuum in GR vs. QFT.That's the perfect way to frame the challenge. A model is only as good as its testable predictions, and I completely agree that this is...

Hi, I'm trying to reconcile the view of the vacuum in General Relativity with the view in Quantum Field Theory. In GR, the vacuum is...
