The plot in question:
It's a figure I made for my #thesis that shows the #relativistic emissivity pattern of an #accretion disc illumed by an off-axis hot X-ray corona around a spinning #blackhole
The radial axis is logarithmic (up to 100 rg). The corona is located at 10 rg on the right. Labels are logarithms of emissivity.
The curvature of spacetime is lensing the photons from the corona onto the innermost regions, and causes the spiral-like deformation from the frame-dragging effect.

Brain twizzler for today continuing down the #angular #momentum rabbit hole.
So what's big and round and spins re-he-heally fast?
How about particles in the #LHC.
Also note that E= MCยฒ is an approximation and the actual equation considers #relativistic speed for #mass.
So.. the question today is.. does the LHC at full power slow the rotation of the Earth because of angular momentum.
Yup.. that's a good one.
#Physicist Fay Dowker & #science #historian David Kaiser give a brief two-minute explanation contrasting the #Newtonian classical view of Time with the #Einsteinian modern or #relativistic view of Time. Nicely illustrated & articulated, not touching on contemporary #quantum Time.

Right - so 2 basic ways to look at it:
Each specialty branch comes up with their own perspectives, priorities/hierarchies, and jargon. With few exceptions, they stay in their own lanes and do not mix outside their field/subfield. Their writings are stand-alone, rarely intended to connect back to the greater human knowledge base. They'll tell you exactly what "wet" or "sound" is, based entirely on their tiny-desk world-view.
The other way would be a general model of vibration, perhaps based on quantitative info rather than qualitative. It would incorporate all modes of vibratory phenomena, regardless of mediums, velocities, or other characteristics that were fleshed out by some subfield as critical for their particular context & definitions.
Frequency (Hz) actually would be a good quantitative baseline for this, if it hadn't been exorcised from #quantum mechanics.
The "old QM", as espoused by the founders and historic supporters for the split in Physics, used a semi-classical approach that was later abandoned. Later, Pi was added to E = hf as convenience for some aspects, but frequency generally falls away when you work with quantum states ala Schrรถdinger. #Time is just an input to QM, and is the #Newtonian, absolute kind. The concepts of frequency & wavelength seem to get in the way of the probabilistic formalism.
IMO, the #probabilistic formalism then gets in the way of a #relativistic completion to quantum theory being developed, though in reality, there is no limit to the imaginative supplemental mathematic epicycles that can be added while still spitting out the same expected answers.
Lightspeed racers game?
Iโve been thinking about a car #racing #game with #relativistic effects in it (though not enough to attempt #programming it myself; front end, let alone #gamesProgramming is not really my thing)โฆ
I imagine we set the speed of light to a human-comprehensible speed, say 100km/h. Our cars have infinite fuel tanks and even brakes, tyres etc. that never wear out or lose grip, and the thrust of really powerful real-world cars, but their length expands and contracts and mass increases with their % of our lowered c according to the usual rules of #relativity. We could even allow for lightspeed lag in seeing them, so a car 500m away would be seen where and as it was 1/200th of an hour = 18 seconds ago.
I think weโd have to ignore time dilation for a multiplayer version of the game, but perhaps that doesnโt matter? My intuitive understanding of of the #mathematics suggests it may be negligible for human noticing until up around 0.95c??? And Iโm not sure that even our idealised car would often get to such speeds? I find it hard to imagine how it affects gameplay, but then again gaining intuitive understanding of relativity is kinda the point here. It could perhaps be done for a single-player version with AI opponents.
Anyway, I canโt possibly be the first to think of such a thing. Does anyone know of such a game? @gregeganSF - is this something you have knowledge of? It sounds adjacent to your kind of thing :)
