Einstein's Ladder Paradox; Simply Explained

- In special relativity, the ladder paradox (or, "barn-pole" paradox) occurs due to they symmetry of length contraction. Here we explore how this apparent paradox can be solved using the relativity of simultaneity.

Great video, but I think Jack should just buy a shorter ladder.
Lol😂
This deserves way more views and likes. Keep the effort up and you'll hit it one day!
Would simultaneity of the barn doors closing in Jack's frame be achieved if the trigger mechanism was not a light beam but an electric current travelling in wires of equal length to each door? Or does electrical current take a longer time to reach and close the left door than it does to reach and close the right door despite the length of the wires being the same?
Nice vid Bean. Ignore the trolls. Although they claim SR or whatever aspect of some science is wrong, they seem to watch and comment everywhere. Lonely guys maybe.
Perhaps a paradox means we misinterpret the concept, assuming two realities cannot exact their rules at the same time (relativity). The reality of the observer and the reality of Jack.
perhaps ur gay
Except that the video explained how both _could_ work. That is the whole point.
The fact that the speed c stays the same to both observers ends up correcting things in the math.
Why is c always the same speed?
Cuz it's super special that's why
Cute video! Ok, the relativity of simultaneity is important...
...But in my opinion:
1) if we consider the motion of the ladder in the barn frame, the length of the ladder does not contract...
and
2) if we consider the motion of the barn in the frame of the ladder, the length of the barn does not contract.
The problem with your analysis is that both Einstein's time dilation equation and Lorentz' length contraction equation, from where Einstein plagiarized his time dilation equation, contain substitutions which make them invalid to use when two objects move or accelerate with respect to each other.
Also not only is there no evidence to support Special Relativity (AKA the invariance of the speed of light with respect to the observer) versus the previous versions of relativity by Maxwell and Lorentz, arXiv 0912.3818
but experiments contradict the Special Theory in favor of a neo-Lorentz Relativity. arxiv 1506.02688
Let me guess: you're a loony?
Relativity of simultaneity doesn't avoid the paradox, as it is another paradox created by the incorrect mathematics of special relativity. According to the correct mathematics there is no relativity of simultaneity or a ladder paradox. These are mathematical errors in the theory of relativity.
Fit it horizontally. Jack knows too much about the difficult stuff and should go back to the basics
Length contraction doesn't exist. It is a mathematical error in Einstein's theory.
The paradoxes are actual contradictions that indicate that the principle of relativity is false. The Einstein mathematics is faulty and produces mathematical contradictions that can not be removed. So his theory is actually invalid as shown by these real unresolvable paradoxes.
No
Nooooo oaaaats
Why the hell is the ladder no longer contracted? We're not talking about a stopped man with a ladder, but a man who keeps moving. Why the hell should the ladder stop being contracted? That's the way it is every time in this relativity subject - nothing but evasiveness.
"Ohhh one twin flew into space and the other stayed on Earth making the astronaut younger than his Earth brother". Except that the Earthling also moved relative to the astronaut because motion is relative! And nobody says anything about it
That paradox is solved by the fact one of them accelerates, and the other doesn't. The one that accelerated is ultimately the one that ends up younger.
The video itself acknowledges that the question of what happens if the ladder stops with the doors closed is one that needs further explanation.
Scientists _want_ the answers to questions. There is no intent to evade as a whole. Scientists work hard to ensure their explanations of observations made about the world are consistent.
@@martind2520 No, they do not want to answer questions. or they only want to answer the easy questions. That's what my personal experience has been. Their explanations for Einstein's nonsense is just more nonsense, like this video. Einstein's simultaneity is just really silly as a concept.
@@everythingisalllies2141 And what are your qualifications in the mathematics of theoretical physics?
@@martind2520 I'm not writing a Paper or proposing any hypothesis. I'm only critically examining the claims made by Einstein, so all that's required is a curious mind and the ability to think critically, and follow what Einstein explained in his Papers. I find that his explanations are irrational and contain many logical errors leading to a false conclusion. Surely you have also found this too, when you read his hypothesis of 1905?
@@everythingisalllies2141 Mathematics is a fundamental part of his theories. You literally cannot understand them without it.
Do you even know how to multiply two matrices?
And no, I didn't find his theories to be irrational, because I understood the mathematics behind them.
