Visualization of Einstein's special relativity

That was pretty good, however most of it still wooshes right over my head.

This is perheaps the most clear visualizaion of Einstein's Relativity I've seen. 5 Stars from me.

what makes you think so?

what mosquitobight excellently said!

light moves in 3 dimensions,i find this illustration wrong,besides everything depends on the observers point of view

but if u never change the position in 1 dimension u can disregard it and take care only about 2, in this case up-down axe is time (duration). The video can help to understand the Lorentz trasformation and Einstein special relativity theory, but u need to know what it ts. U cant understand one of the strangest phisic theory by seeing a video on yt.
btw in the video there are 2 pov (ground & cart)

Light having weight or everything moving in waves?
For the light, I forgot exactly why, but my AP Chemistry teacher told me. For the waves, same thing.

PART 3

Second, we see the light go from the guy to the mirror in 1.733 BOAS, and go back to the guy in 0.577 BOAS, for a round trip time of 2.31 BOAS. But for the guy, the round trip time of the light is still exactly 2 BOAS, and he tells us so. We must conclude that for him, time has slowed 15.5 percent.

PART 2

Now, suppose the rocket goes by us at half the speed of light. First, we see the rocket (and therefore the distance between the guy and the mirror) has been shortened to 86.6 percent of its stationary length. To us, the guy-mirror distance is 26cm (10.6 inches.)
