it is more advanced than that

if anything moving at the speed of light had mass, then the equations we have (that seems to fit all observations)would imply that it would have infinite momentum, it would take infinite energy to accelerate to that speed and time would move "sideways", not forward or backward, but sideways. also it would create instant black hole.

these are some the conclusions one can draw from the observed data.

black holes are the craziest things in the world. as much as my father tries to explain them to me, i simply can't wrap my head around the notion.

please do tell more about your father's expertise on black holes... ><

black holes were by far the most understandable thing to learn about in quantum.

pretty sure i never said he was an expert. he's just a lawyer, but he happens to be smarter than you (and many other people), so he understands the concept somewhat well. >.<>.ds<<.8======D

harry, not to insult, but how smart your father is, or that he is a lawyer, has little to do with how well he understand quantum physics.

black holes are sort of the easiest thing to understand, because it is one of the few things that are similar to the world we actually live in. so it is actually possible to think abit about them without any training.

where they get difficult is the fact that science really doesn't understand them. it is difficult to figure out how someting can be so heavy it acually bends space and time.

lol what in the world i live in is similar to a black hole?

well, close to a black hole, the laws of causality is still not broken.

that is, cause happens before effect, which is DIFFERENT than in other quantum physics.

close to a black hole, stuff only do one thing at a time, which is different than in quantumphysics where particles spinns in all possible directions at one time, and are doing EVERY posibility.

a black hole you can think about by envisioning it in pictures from our own world.

we can't even explain how an atom looks. instead we have like 5 different explanations of how to think about it, all of them completely differet.

black holes are easy to understand?
let me ask you to explain me something: you see something, i.e. me, flying "in" a black whole. "in" means crossing the horizon of events. you'd see me reach it, but from my point of view, the space would get stretched that much, that i'd never reach it.
sry but explain me that. yeah, sure, you have "another" time. really, no way, that isn't the world i'm living in.

i'd like really to hear that smart daddy who understands black holes and everything which this implies. we just know nothing about them.
what happens with all the information that's getting "trapped" "in" there but ofc without even reaching it. why and how do they emit radiation...

back on topic. talking about "if anything moving at the speed of light had mass" gets us to a nice topic. duality. matter changing into waves and vice versa. it's not matter which travels at light speed but the electromagnetic wave you got the point. those waves might be of interesting. as there's another "force" which isn't bound to the speed of light. gravity has an instant effect. we could exchange informations over an infinite distance in NO TIME (as gravity never reduces to 0, no matter how far the source of it is away). are there any particals involved? we just don't know it for sure. *sigh* but it seems pretty sure that it has something to do with space itself. it just changes. how exactly? well, back to black holes: i have no idea!
but not only gravity doesn't need time. particals neither. at least entwined particles don't need it. *sigh again* so WTF is wrong with time? where's that daddy who knows how those black "holes" work?

the holy string theory: 1+1=0. i just need to be in the right field/corpus [not sure if it's the right translation]. that's the string theory: if it doesn't work the way it should, we might find some way that it fits. hey, let's get some new dimensions! wait, why only new dimensions, let's get a 0-dimension too! i admit, it explains things. but surely is not unification of the theories, which makes it obsolete before it's even completed. it explains causality without even needing it! doesn't sound bad, but well, newton sounded good too, so does the pope.

no need to argue about things [i ofc enforce talking about them] where we're having no idea about [which i suppose none of us really has; not even daddy]. which is for sure that if these results are correct, it's a really great, i mean really fucking great discovery! can't wait until they find an explanation [not just some mathematical model which is able to recompute the results]!

ty for sharing this kreuzfeld as i completely missed it!

didn't say black holes where easy to understand, I said it could be the easiest thing in a quantum physics class. which means it can still be very hard to understand, BUT quantum physics is much HARDER to wrap your head around.
