Einstein's Special Theory of Relativity explained!

Events may appear simultaneous for one observer but not for the other. #shorts #einstein #specialtheoryofrelativity #einsteintheory

*What other explainers would you like to see?*

But the events happened at the same time in both cases.

It just took longer for light from the lightning strike on the back, to reach the observer on the train, because she was speeding away from it. It literally had to travel further to reach her. But that doesn't change when the events happened, they were still simultaneous.

Observation doesn't change anything about the events, themselves.

The triangle of lights paradox. There are 3 lights in the form of a triangle. A, B, and C are lights and are stationary with respect to each other. S1, S2, S3 are spaceships. S1 is moving from B towards A. S2 is moving from C towards B. S3 is moving from A towards C. A, B, and C flash simultaneously in the frame of reference that is at rest relative to these lights. So in the frame of reference of S1, A flashes first followed by B flashing. In the frame of reference of S2, B flashes first followed by C flashing. In the frame of reference of S3, C flashes first followed by A flashing. So the sequence of flashing is A, B, C, A. But wait! A flashed first. How can it flash last? How can A flash both first and last? It only flashed once in the frame of reference that is at rest relative to these lights. Therefore there is a paradox.

not a good explanation. it doesn't show the light of the lightnings travelling towards the observers - one at rest, the other in motion - showing a different "hitting" order. Plus: both can claim that they are at rest and the other is moving, therefore there's no *absolute* simultaneity order possible. (which is why it's called *relativity* )

Don get it, you made me forget physics😂

Nether person is experiencing the "events" it's only the train that does. It's only the thing that's being struck by both lightning strikes. What either person experiences is "information" about the two events which is being transmitted at the speed of light to each person. The acrual events themselves "the strikes" are not being transmitted.

Try this experiment: Watch a sporting event that involves referees or judging. Pick an event you have no loyalty to any of the participants. Let's say an American football game. Look for the reaction of the home crowd on a close call not favoring the home team. To you the call seems obvious. But to the biased observers it is a crime. Where you sit can often determine your view.

It's easier to explain with 'Back to the Future' movies: Even though Marty & Doc traveled to the past & the future, they both grow older.
So that they both experienced time continuously, while seeing their older & younger selves.

You say.. the easiest way to understand theory of relativity
... But what you are talking about i can get it... Its the hardest way to understand

[RyadStar]

That's just the result of the finite speed of light

[sspoonless]

No. Only if the train is moving. Your depiction showed the train stopped.

[MarkSmithicu]

You explained it wrong. The lightening strikes occur on the platform, not the train, . You also made no mention as to the uniform speed of light, regardless of motion.
All due respect, that made no sense whatsoever..

[NicleT]

I mean, we can't see the strikes. Not a good video for a short.

[AprendeEmprendeyMonetiza]

Mmmmh 🤔🤔🤔 this doesn't really help how is the person from the train looking at the lightning from behind, now I'm even more confused 😕 than beofre😢

[AprendeEmprendeyMonetiza]

Respective frames? or respective positions, respective point of view or respective reference point?

"In May and November, the Earth is moving at "right angles" to the line to Algol. During this time we see minima happening regularly at their 2.867321 day intervals. However, during August, the Earth is rapidly moving towards Algol at about 107, 229 km/hr as explained on my How Fast Are We Moving? page. (The Earth moves approximately 202 times its own size in one day.) So in 2.867321 days the Earth moves about 7, 379, 039 km closer to Algol. _But the varying light from Algol doesn't know this - its light waves left Algol 93 years ago and are travelling at a constant speed._ The result - we "catch a bunch of minima early" during August as shown on Chart 2. Exactly the opposite happens during February - the Earth is moving away from Algol that fast and it takes longer for the group of minima to reach us so we see them taking longer between events. How long? 7, 379, 039 km divided by the speed of light 299, 792.458 km/sec is 24.61382 seconds. So in May and November when we are not moving towards or away from Algol - the period seems constant. It is our rapid movement towards or away from the events in August and February that causes the timing differences."

I assume that light is passing the earth at c when the earth isn't moving towards or away from Algol.

In February the earth is moving away from Algol and the time between the eclipses is 2.8675875347 days and the light is passing the earth at 186, 265 mi/sec.

In May and November the earth is not moving towards or away from Algol and the time between eclipses is 2.867321 days and the light is passing the earth at 186, 282 mi/sec.

In August the earth is moving towards Algol and the time between eclipses is 2.8670608912 days and the light is passing the earth at 186, 299 mi/sec.

[Smxlldivine]

My main question is WHY, why does this happen, idc about the perspective, WHYYY does space time curve so much becoz of light dilation

[BaronLucid]

The single worst explanation of special relativity I have ever heard, she must be sadistic
