Like.
It was. We are supposed to be an educational site. That is our stated goal and mission. I hope my colleagues here can look at your... -
PeterDonis reacted to PeroK's post in the thread I I don't see how a black hole's event horizon can be crossed with Like.
I admit haven't done a scientific analysis, but I think it's almost impossible to understand relativity without studying it from an...

PeterDonis replied to the thread I Question about discussions around quantum interpretations.I don't see how this is a viable claim, since the screen does not exhibit any of the behaviors we exhibit as agents. I know this is the...

PeterDonis replied to the thread A three month long summer vacation from public school seems stupid.And I learned a lot about how not to use high explosives from watching Wile E. Coyote and the Road Runner. :wink:

No we wouldn't. It's basic psychology. No amount of wishfull thinking on your part will change the way humans, and in particular humans...

This is worth repeating, I think, so as not to discourage the OP: He may not be getting he answers he asks for, but it's not because...

No. It's showing accumulated time of his clocks minus a lab clock (hence the vertical axis being "residual phase"). The comparison is...

PeterDonis replied to the thread B Project GRE^2AT - GR on Mt. Ranier.Yes: he was up there for "a full two days". Your result is ns/day, so you need to multiply by two. :wink:

PeterDonis reacted to Dale's post in the thread I Variation of the lightning train thought experiment with Like.
Length contraction is the comparison of a length in a frame where it is at rest vs the length in a frame where it is not at rest. Light...

PeterDonis replied to the thread I I don't see how a black hole's event horizon can be crossed.The correct premises are the black hole models that have been built using GR. Understanding them requires taking some time to learn...

PeterDonis replied to the thread I I don't see how a black hole's event horizon can be crossed.I agree with this, but I think one also has to be realistic about just how much one has to learn--and unlearn.

PeterDonis replied to the thread I I don't see how a black hole's event horizon can be crossed.This is a question of philosophy, not physics. In physics, we build models and use them to make predictions. Sometimes the predictions...

PeterDonis replied to the thread I I don't see how a black hole's event horizon can be crossed.Not if the answer is "it's not even wrong". Your analogy is too far off to even be corrected. You're better off just throwing it away...

What you see as a "path to learning" looks like a confusion of ideas to me. That said, you have to choose your own path. Where that...

PeterDonis replied to the thread I Gauss' law seems to imply instantaneous electric field propagation.Yes. The current might be constant but the charge density is changing with time, so what I said still applies. Not the way you're...
