@EchoesTimeHQ I remember it, I was at that show of hands vote on the last day of the IAU Conference in Prague.
@mathemetica A fourth axis is needed with the number of particles N and therefore with Statistical Mechanics
When Gravity acts in vacuum, two observers under free fall notice the tidal field ('electric' Weyl tensor) and if they are carrying gyroscopes, they notice the frame-drag field (or `magnetic' Weyl tensor). This frame-drag field has no Newtonian analog. arxiv.org/abs/2608.19260
@PhilosophyOfPhy But in General Relativity the pressure is a source of the attractive gravitational field, so pushes inward, pulls.
@Math_files Even if the atomic hypothesis of Boltzmann was showed. :-)
@Math_files As the number of pages was inferior to 24, the Ph.D. Thesis of Einstein was a brochure!
I have never understood the supposed importance of Olbers' 'paradox' of why the night is dark and not totally bright. Its hypothesis that the Universe were infinite, eternal, static and uniform are false. The Universe is finite, begins in time, it is in expansion and in evolution
The darkness of the night sky seems so ordinary that it is easy to forget how strange it actually is. If the Universe were infinite, eternal and static, with stars distributed more or less uniformly through space, then wherever we looked our line of sight should eventually
@WKCosmo @TradeTexasBig Correct and publish your Lectures! Thanks in advance!
@RobJLow @Quasilocal @Mat_Hunt @WKCosmo Penrose has written a GRG paper in the 70's entitled "The nonlinear graviton".
Good dissemination of how in Einstein's theory of gravity the speed of propagation of gravity is finite and equal to that of light.
Gravity can’t be an instantaneous force In Newton's gravity, the force was instantaneous and worked across infinite distances. According to Einstein, that can't be right. bigthink.com/starts-with-a-…
@RobJLow @Mat_Hunt @WKCosmo @Quasilocal By the way, I recommend then wiki article on "The speed of gravity". For me, this "speed" is the velocity of the gravitational waves.
@RobJLow @Mat_Hunt @WKCosmo @Quasilocal I remember that Belinskii and Kalashnikov worked on solitonic solutions, but in 2+1 dim.
@pascalkwanten Yes but only in Maths, because it is human invention, even different infinities (alephs) and Cantor transfinities can be defined.
The transcendental number Pi, from Geometry to Physics.
Pi is woven into the laws of nature itself. Planets obey a³/T² ≈ GM/(4π²). Quantum limits follow Δx Δp ≥ h/(4π). Spacetime bends with 8πG in Einstein's field equations. Electrostatics carries 1/(4πε₀). Columns buckle at P_cr = π² EI/(KL)². Pendulums keep time as T = 2π
Well done!
Visualization of the Maxwell–Boltzmann speed distribution. Showing how the same 300 argon atoms produce a finite-sample histogram while the smooth line gives the exact equilibrium distribution. f(v;T) = 4π(m/2πk_BT)^(3/2)v² exp(−mv²/2k_BT) Temperature does not give every atom
A remarkable paper on several representations of Schwarzschild spacetime (embedding, Tortoise, Kruskal, Diamond) that correspond to the vacuum spherically symmetric solution of Einstein's equations of gravity. A new Golden representation is introduced. arxiv.org/abs/2608.07909
