That is a good question. If you have a pseudo-Riemannian manifold and remove the metric then you are left with a topological manifold...

Interesting. I was not aware of that. Do you have a reference for that?

Hello everyone, I am a Master’s student in theoretical physics currently studying the Kerr–Newman black hole solution. I would like to...

Why? It seems very clear that for every point “up and to the left” there is a symmetrical point “down and to the right”. Using that fact...

If I have time, I'll look at the details of what you've done. In general, if you have two limits, then the order can make a difference...

Einstein came up with a lot of formulas. Do you mean the time dilation formula: $$\gamma = \frac{1}{\sqrt{1-v^2/c^2}}$$ If so, for...

Do you have something against symmetry? I mean, is there a specific reason that you are going out of your way to avoid using symmetry?

For a ship (with nonzero rest mass), it cannot achieve "the speed of light" physically. Although your Newtonian intuition suggests that...

A clock can't travel at the speed of light. All motion between you and a clock is relative. If the clock is moving at 99% of the speed...

For light proper time (what clocks measure) is undefined. What is mathematically defined for light is called an affine parameter...

Be highly skeptical of any source that you read which discusses what happens on a ship that reaches ##c##. It might be a great science...

Not much for every day life. But if you were tasked with building a rotating space-station, were the perimeter moves at a relevant...

In ordinary code when a bug arises it isn't because we cannot predict the behavior, it is because we did not predict the behavior. There...

I would challenge anyone to predict a specific hallucination given a trained deep neural network. I am not limiting it to LLM’s, but not...

Then why do they hallucinate? They hallucinate precisely because the developers cannot predict that behavior by analyzing the parts. The...
