PeroK replied to the thread I How Can Photons Be Massless Yet Have Energy According to Einstein's Equations?.The equation ##E = mc^2## only applies to a particle with mass. And, indeed, that's its energy only when it is at rest. The full... -
PeroK reacted to PeterDonis's post in the thread I Prof Mike Wiest's proposed link between quantum and consciousness with
Informative.
As far as his claimed effect of microtubule-binding drugs on anesthesia, I have no idea. That sort of discussion belongs in the... -
PeroK replied to the thread Yikes! Autonomous cars to control intersections, drivers be aware!.You've got bigger things to worry about than autonomous cars. It's all a distraction from what really matters.

PeroK replied to the thread Hey together.Welcome!

PeroK replied to the thread B How to derive the 4 laws of motion using Calculus.You can't. The laws of motion are physical laws, independent of the foundations of mathematics. The laws can be stated in mathematical...

PeroK replied to the thread B Is there a white hole inside every black hole?.A singularity is simply where the mathematical model breaks down. It's not something physical. A theory of quantum gravity would have no...
-
PeroK replied to the thread I Is calling fictitious forces "not real" just about terminology?.Fictitious, inertial, pseudo, what does it matter!

PeroK reacted to PeterDonis's post in the thread B Is there a white hole inside every black hole? with Informative.
That's correct. More precisely, in an FLRW universe with zero cosmological constant, it's correct. In fact I'm not even sure if there is...

PeroK reacted to Ibix's post in the thread B Is there a white hole inside every black hole? with
Like.
I'm not sure you can even have true black holes in an FLRW universe, because a black hole is a region of spacetime that can't signal to... -
PeroK replied to the thread B Is there a white hole inside every black hole?.It seems to me that a white hole is a mathematical concept that is largely irrelevant to the physical sciences.

PeroK replied to the thread Mount Everest (Qomolangma, Sagarmatha) Weather and Exploration.That sounds like one of my recurring mountain bad dreams, where I find myself on an Alpine or Himalayan mountain, having dressed and...

PeroK reacted to marees's post in the thread B Is there a white hole inside every black hole? with
Haha.
This is what I am thinking. How much feasible is it? There is a white hole inside every black hole The white hole spits mass/energy... -
PeroK replied to the thread I Is calling fictitious forces "not real" just about terminology?.I broadly agree. Perhaps this is one of the great things about studying mathematics. That you learn to think in terms of the...

PeroK reacted to Hornbein's post in the thread How Vulnerable Are Large Language Models to Malicious Data Poisoning? with Informative.
Here's the paper. https://arxiv.org/abs/2510.07192
