I fear God so much that I don't pray or go to church because I don't want to bother Him.


DESI experiment means Milne model comeback? arxiv.org/pdf/2011.12146 x.com/blamblamtheman…

Similarly, I think Mach's principle and the incompatibility in SR between a homogeneous and evolving distribution of matter have also just been kind of ignored in the face of GR's empirical success. Maybe at least worth knowing the basics of the older theories, like Milne model



"We will use the convention (+, -, -, -) ..." - stopped reading.


Found the answer in this banger: arxiv.org/pdf/gr-qc/0405… x.com/blamblamtheman…

Why does taking the zero-grade in the this manner get you the correct Lagrangian and stress-energy tensor? Did someone else notice this? How to show equivalency to varying the action?

Newcomb's problem's problem: Omega puts $1000 in box B, and tells you he will put $ 1 million in box A only if he predicts you will only take box B, and $0 if he predicts you will take both. Then he secretly gives everyone who took both $5 million.


Been really into the idea that spacetime is information theoretic in origin recently, but didn't have a good reason why an information metric would yield three spatial dimensions. But now? Hmmmm... arxiv.org/pdf/1206.0630


Einstein 1905: No so thing as the aether, don't be ridiculous. The laws of motion do not depend on some background field. Einstein 1915: It's called spacetime, it's like a medium that everything propagates through and determines inertial frames for the laws of motion.
