Theory of Relativity - The Basics
The Theory of Relativity, proposed by the Jewish physicist Albert Einstein (1879-1955) in the early part of the 20th century, is one of the most significant scientific advances of our time. Although the concept of relativity was not introduced by Einstein, his major contribution was the recognition that the speed of light in a vacuum is constant and an absolute physical boundary for motion. This does not have a major impact on a person's day to day life since we travel at speeds much slower than light speed. For objects traveling near light speed, however, the theory of relativity states that objects will move slower and shorten in length from the point of view of an observer on Earth. Einstein also derived the famous equation, E = mc2, which reveals the equivalence of mass and energy. When Einstein applied his theory to gravitational fields, he derived the "curved space-time continuum" which depicts the dimensions of space and time as a two-dimensional surface where massive objects create valleys and dips in the surface. This aspect of relativity explained the phenomena of light bending around the sun, predicted black holes as well as the background radiation left from the Big Bang. For his work on relativity, the photoelectric effect and blackbody radiation, Einstein received the Nobel Prize in 1921.
Theory of Relativity - Inherent Limitations
For the past century, scientists have conducted a variety of experiments to verify the implications of the Theory of Relativity as well as advance fields such as cosmology and particle physics. However, there is some question as to the ability of Einstein's Theory of Relativity to describe as many physical phenomena as has been claimed - with some scientists arguing against it entirely. Regardless, as with any other scientific theory, it is not the absolute, entire and final description of the universe. Because it is a scientific theory, it contains certain assumptions and approximations of nature and ultimately, fails to describe several phenomena altogether (i.e. electromagnetism). Unfortunately, Einstein's Theory of Relativity, much like Darwin's Theory of Evolution, has become popularized as a "scientific truth" because it offers a simplified explanation to the complexity observed in the natural universe. In fact, Einstein himself spent the rest of his life attempting to develop a Unified Theory of Physics which would combine electromagnetism with relativity. He was unsuccessful and to date, this task has not been accomplished.

And this video makes people look stupid, you have to be not understanding distortions, A fire can distort your view as water can or other moveable transparent, why is so hard to understand light, when anyone knows that we see only the light and because the light is not infinite in speed or is not always constant we can have distortions of perception, it’s not hard to understand, the mathematics are not hard, but relativity engulf more and because of it simple becomes complicated.

@klkiktkhk Tx for RE but my post is divided in 2 parts:
1 the impossible deduction of the speed of light in short distances by a man,referring to the narrator and the analogy that he makes.
2 the theory its self,which is not responsible for much (rather than the obvious) but given a lot of importance,and unfortunately is a bad thing in law,because now everyone can easily say that he saw something else since there isn’t something common in perception of events. Why Einstein is up and not Tesla?

@EterIronGen Ofc it's not to be taken direct. It's just an explation and a very accurate one at that. They could even do it easier with just the friend walking in one direction. He proberly wouldnt know, but the strike he is closest to upon impact would be the first light that reaches him. This has nothing to do with the perception speed, but how the _THEORY_ works.

Let`s say that whit sound I would agree but light?
This narrator knows the speed of light?
The train has to move very quickly to delay the perception of the observer, like 200 times more faster than any train.
The theory is ok but is not as important in the big part of the science and unfortunately has a bad implication to social and law interpretation,
So it may be true but is not something that we have to take to direct.

the observer looks like a serial killer... seriously

@Mostwantedo Because, from the passengers point of view, they were not simultaneous. That is the key to Relativity. The observation of a light is "Relative" to the viewer. If you think that this is confusing, try & imagine the flow of Light & Time if you could stand just to the outside edge of the Event Horizon of a Black-Hole. Ponder that one for a while.....

@TheAtheistworld That would depend upon wether you are "Kicking me in the ass" in the world of Quantum Mechanics, OR, in the world of Relativity?
Technically speaking though, it would actually be impossible for you to "kick me in my ass" because, the millions of electrons orbiting the millions of atoms that make up the matter that you visually "SEE" as your foot are actually electro-gravitationally repelled by the millions of electrons
orbiting the millions of atoms you "SEE" as my ass.

@AlexHated Ah yeah I got that now long time ago, but I've heard that it really ''happens'' before the rear lightning, like the passenger was ''time traveling''. But it's just an illusion, right? They still happen at the same time, she just sees them not simultaneously.

@Mostwantedo because, as the train is moving towards the front light, the passenger meets the front light before the rear, and as she is travelling away from the rear it has to 'catch up' with her so it takes longer for her to see it.

I just still don't get it. Why would the passenger see the lightnings not simultaneously?
