#GeneralRelativity

We just posted a new #AI paper on how to auto-discover laws of physics from raw warped video with machine learning. It took Silviu & me a year to get this working, using ideas inspired by #generalrelativity & high-dimensional #knottheory - phew!

Interesting debate: physics suggests a "block universe" where past, present, and future exist simultaneously. Is our sense of time an illusion? #physics #GeneralRelativity #BlockUniverse #PhilosophyOfTime @QuantumTheory

Time moves slower near massive objects ​If you spent 1 hour orbiting right outside the event horizon of a supermassive black hole over 7 Earth years would pass for everyone back home #Physics #Generalrelativity #Blackhole

Beyond the P Value Ep3 You are just trying to move straight into the future, and the Earth's mass is steering your path through time toward the floor. ​Paper: Sitzungsberichte der Preussischen Akademie der Wissenschaften zu Berlin (1915), 844-847. #generalrelativity #Einstein

A description of what local and global #Lorentz frames mean in relation to #Einstein's Principle of Equivalence in #GeneralRelativity. (This is a warm-up for an upcoming post on how physicists transport #Dirac's equation for fermions to curved spacetime.) #physics #math #geometry

In this doc, I explained general relativity purely mathematically—from Lorentzian manifolds and the Levi-Civita connection to curvature tensors & the Einstein equations. I even added color to headings & formulas! Check it out! #GeneralRelativity #Math

#Microrobots can now navigate complex environments using "artificial spacetimes," a geometric control framework inspired by #GeneralRelativity, enabling scalable coordination without onboard computation. @nature

Dr Stuart Marongwe believes he may have a solution to the vexing incompatibility of #GeneralRelativity and #QuantumMechanics theories. His theories could bring us one step closer to the long sought after unified theory of #quantumgravity.

Originally, a geodesic was considered the shortest path between two points on Earth, but the term has been generalized. Timelike geodesics in #GeneralRelativity describe the motion of free falling test particles. A freely moving particle always moves along a geodesic. #MathType

Maxwell's equation for the electromagnetic field in vacuum can be derived from Einstein's equations in the generic case. (Though there are some exceptions.) Here are steps for a proof (step 2 being the tricky one). #physics #generalrelativity #electromagnetism #math #geometry

#GeneralRelativity, Einstein's theory of #gravity, is often regarded as physics' most beautiful theory. It's geometric, universal, & parameter-free. But #DarkEnergy, #quantum physics, and #StringTheory theory all raise aesthetic questions.

#Physicists introduce "supermazes" to map black-hole microstructure, offering a detailed view through #StringTheory. This approach enhances understanding beyond #GeneralRelativity's limitations. @USC

The Einstein field equations describe how matter and energy shape the geometry of space and time. They connect the curvature of spacetime with the distribution of mass and energy. How familiar are you with the theory of General Relativity? #Math #Physics #GeneralRelativity

An atomic clock measured how general relativity warps time across a millimeter. ⏱🤯 #AtomicClock #Millimeter #GeneralRelativity #Time #Physics @ScienceNews
