10:14 I love the fact how both the drivers saved the girl...amazing 😮
@maestro2173
This is the best one I’ve seen so far, this seriously and sincerely deserved more views. Somehow or another visualizing these concepts clicked a lot more in my brain. You are an inspiration.
@Ty-12x
Your bending of space time animation towards the end when you were explaining Lorentz Transformations was simple, but one of the best ways I've visually seen it expressed!! Very cool
@winstongsd4273
the part of the graphic when the grid is angled really helped me understand how the observers see time dilation. thank you.
@fazlulrahman2804
This is one of the best illustrated explanation of special relativity I ever watched so far from YouTube ❤️.
@mavelous1763
I need to rewatch this about 10 times just so I can fully not understand it
@emenikevictor5118
Am so grateful I haven't seen an explanation as clear as this thanks

6:40 In the video, both were in motion across the dimension of time at the same speed. This is incorrect. However, both are actually sharing an equal magnitude of ongoing motion within the 4D Space-Time environment. Each person is in motion within Space-Time exactly as much as a photon of light is in motion across space.

Four-Dimensional Space was developed by Minkowski (who gave us the “Light-cone”). In Einstein’s article of 1905, he treated Space and Time separately. In fact, Einstein stated that “he no longer understood The Special Theory of Relativity” after Minkowski’s lectures. However, Einstein soon adopted Minkowski’s Four-Dimensional point of view (and built on this to develop the General Theory of Relativity in 1915).
@JadeLivao
Fantastic explanation of dimensions and the role of time! Loved the clear discussion on relativity, coordinate systems, and spacetime diagrams. Thanks for making complex concepts easy to grasp!
@LIGHTNING_3-
⚠️PLEASE READ THIS⚠️ This was such a great explanation on relativity I have seen but but ⚠️ Brother you have done a mistake in this video that is you said a point of singularity a 1 dimensional object which isn't true. A point is a 0 dimensional object with no length width or height, then comes 1 dimensional object for example a line, a line has length only so it can be considered as 1 dimensional and not a point object, then it is followed by 2d and 3d which was correct in video. HOPE THIS HELPED 👍
@m0nk3yl0v3r
The amount of effort thast gone into this video is insane... so amazing to watch and learn from
@drgroove101
This video is really well done. I still have trouble understanding how space literally contracts and expands, the graph at 13:48 helps, and has been the best visual aid I've seen in any video.
@philoso377
Nice video and presentation. An elite learns and think straight but deep. Elites learns the Theory of Special Relativity fast and can’t tell that is true or false.

I got lost at 11:10. It is my understanding that the sky is black at night, despite the existence of an uncountable number of stars because the light from those stars must travel distances that are greater than the speed of light allows. If it were possible to travel along side a single beam of light, looking forward, we would see nothing, because the light could not go faster than its limit.

Experiments supported by theory, by many independent researchers, now show that EM fields propagate instantaneously in the nearfield and reduces to about speed c in the farfield, after propagating about 1 wavelength from the source. In one experiment, a sinusoidal signal was transmitted between 2 dipole antennas as they were separated from the nearfield to the farfield. Analysis of the resultant phase vs distance curves (dispersion curves) shows a clear minima in the nearfield for all the EM field components. Applying well known phase speed and group speed operators to the curve, which are inversely proportional to the slope of the curve, show that both the phase speed and group speed are instantaneous in the nearfield and reduces to about speed c in the farfield. In another experiment just peer reviewed and published in the EM journal IRECAP, shows an EM pulse propagating 1.5m in the nearfield with no propagation delay. This shows that the front speed, or the speed of information is instantaneous in the nearfield. If speed of light is not constant, then the 2nd premise in Relativity is wrong and what remains is the 1st premise: Galilean Relativity. Instantaneous signals violate the Relativity of Simultineity because the signals appear the same in all inertial frames of reference. This can easily be seen by inserting c=infinity into the Lorentz transform, yielding the Galilean transform, where time and space are absolute. So if a moving body is observed with instantaneous nearfield light, then no Relativistic effects will be observed. But they will be observed if the frequency of the light source is changed such that farfield speed c light is used. So by simply changing the frequency of the source, Relativistic effects can be turned off and on. The only possible explanation is that the effects of Relativity are not real and are just a type of optical illusion. This result will affect all of modern physics.

Phenomenal diagrams for simple understanding.
@vesuvandoppelganger
There are 2 contradictory time dilation formulas that can be derived from SR. If the distance between the light source and the mirror on the ceiling is L and the train moves to the right at c/2, the light travels 2L for the observer inside the train but (√5)L for the observer outside the train for the roundtrip. Since c is the same for both, it takes time 2L/c for the observer inside and time (√5)L/c for the observer outside. From this we can derive the time dilation formula T=T_o/(√(1-(v^2/c^2))). Now, when light is shot vertically toward the ceiling but at an angle to the left, say arctan(0.5), and the mirror on the ceiling is moved accordingly to the left to reflect the light correctly, the light travels (√5)L for the observer inside the train but 2L for the observer outside for the roundtrip. Since c is the same for both, it takes time (√5)L/c for the observer inside and time 2L/c for the observer outside. From this we can derive the time dilation formula T_o=T/(√(1-(v^2/c^2))). The variables are switched and the formulas are contradicting each other. This shows that SR is invalid.

Thanks, very well explained (and I appreciated the metric measurements)
