Dale replied to the thread I Board Breaks: Small or Large Deflections?.I wouldn’t trust anything physics-related from a modern LLM. They all hallucinate frequently. Only after the board is broken. To me the... -
Dale replied to the thread I Board Breaks: Small or Large Deflections?.Looks like pretty small deflections to me: Unfortunately, my Google-Fu was not sufficient to find a really fast video where it could...

Lorentz contraction affects both, positive and negative charges. But only the positive charges (atom cores) have fixed proper distances...

Like.
The two definitions : The Levi Civita Alternating Symbol is defined as below, taken from here. I put the relevant image above to the... -
Dale reacted to weirdoguy's post in the thread B Does the gravitational distortion of mass still exist in the past? with Like.
So I wonder why did you come to scientific forum then. Universe doesn't care about your views, it works the way it does, we can't pick...

Dale reacted to Ibix's post in the thread B Does the gravitational distortion of mass still exist in the past? with Like.
Unfortunately, the maths disagrees with you. Whether there would be a trail behind a 3d object moving in a 4d spacetime is unanswerable...

Dale reacted to PeroK's post in the thread B Does the gravitational distortion of mass still exist in the past? with Like.
The Earth is physically a 3D object in space, but it's a 4D object in spacetime. In Newtonian (Classical) physics, vectors are...

Dale reacted to sophiecentaur's post in the thread I Energy of Electromagnetic Waves in Destructive Interference with Like.
The 'information' that governs the interference pattern is contained in the waves themselves (wavelengths and amplitude in every...

Do you have a reference that supports this? It looks like personal theory to me, which is off limits here.

Dale replied to the thread Comments from "Does the gravitational distortion of mass still exist in the past?".The one that @PeterDonis asked you for was correct and consistent. You should have responded to that request seriously. :rolleyes...

It does, if after "in informal terms..." you write some nonsense.

Ah - so (dropping a dimension for ease of visualisation) you (and @Dale) think the OP's mental model is that spacetime is a 3d block...

Dale replied to the thread B (Electric) current is not a vector quantity.As I have said several times, current does not have a direction (left or right, up or down). It only has a sense (in or out). Current...
