- "Noone has ever been able to define the difference between interference and diffraction satisfactorily. It is just a question of usage, and there is no spec...
- Yes, but is there a violation of the WEP (Weak Equivalence Principle)? Bend it Like Newton Yesterday’s post on testing the assumption that photons are m...
- TThe AdS/CFT duality relates a theory on the boundary of a region to a theory with gravity in the interior. The AdS/CFT duality is a concrete example of holography, which sugge...
- According to the laws of physics, the speed of light is a fundamental barrier that cannot be broken - nothing is supposed to be able to travel faster than it. So astronomers w...
- A Fukaya-Categorical Analysis Of The Sasaki-Einstein ‘AdS/CFT’ Holographic Renormalization Of Quantum Gravity
The planes of constant t intersect the hyperboloid in 2d spheres.

Is Spacetime Countable? Written by Sean Gryb and illustrated by Marc Ngui Abstract Is there a number for every bit of spacetime, or is spacetime smooth like the real line? T...Penrose diagram showing the layered structure of the near horizon region of an ADS black hole
