# Why Special Relativity is wrong and the speed of light is NOT the same for all observers

Hi, I hope to make this accessible to as many people as possible.

Special Relativity tries to make the argument that a moving observer will measure light to travel at the same speed as a stationary one, and indeed that all reference frames are equal.

This replaced the concept of a reference frame provided by a fixed or entrained medium of space , an ‘aether’, there is evidence against the fixed type but none against the entrained variety.

The speed of light is measured at 299,792,458 meters a second on earth in a vacuum from the earth frame of reference.

If a pulse of light travels along a train track past a train moving in the same direction, we would expect the motion of the train to slow the speed light seem to be moving as measured by the train.

Special Relativity argues that there are 2 effects that take place to ensure the speed of light it still measured the same by the train passengers.

First is length contraction, this is where the train gets slightly shorter the faster it moves, and because there are no preferred frames of motion the world seems to shrink from the train passengers reference frame.

If the speed of light is measured by 2 sensors 1 meter apart with a clock to detect how long between the first and second sensor take to be triggered, then motion in the direction of the light will make the delay longer (light will seem slower) but the contraction of length as seen by earth reference will shrink the 1 meter separation to a smaller distance, this will compensate so the time it takes matches the Earths measure for the speed of light.

And there is a second way that Special Relativity tries to explain this, with time dilation.

That is the rate of time on the train slows the faster it moves, as such even if the light has further to travel when the train is moving with the light, it will measure the speed the same since all clocks on the train will run more slowly which would cause the the delay to be measured as less on the train than off.

Both of these effects would work together to increase the measured speed of light so it measures the same as a stationary viewer despite being seemingly slowed by the motion of the train.

Amazingly this whole thing falls apart if which we are measuring light moving with the train, we also try to measure light moving in the opposite direction.
Now the speed of light should be found to be higher because of the motion of the train adding to the velocity between the light and the train.

But here the length contraction makes it worse, the meter separation of the sensors shrinks causing the speeding light to be measured to be even faster, and as the clocks on the train are observed to slow, even less time passes between the light hitting the 2 sensors.

All these tricky that relativity only works in one direction, in the other direction it makes the difference even worse than it would be.

This proves that the speed if light can not be the same for all reference frames.
Special Relativity simply fails.

But there is more.

Time dilation can’t exist either.
Special Relativity holds that all frames of reference are equal, so time might to be moving very slowly when we look at a spaceship moving near the speed of light, but on that spaceship they would see us as moving very slowly.

This is always given from the point of view of a spaceship leaving earth.

But this fails to take into account the Doppler effect, this is the that changes the sound of a car horn or engine when it moves towards you .vs when it moves away.
If I was shooting an automatic gun at you in a car that was approaching you, you would find the bullets coming at a swifter rate than if I were stopped, and a slower rate if I were driving away.

That is because when I am getting nearer each bullet has less distance to get to you. And if I am driving away each bullet has a greater distance, which makes it seem that time has slowed down in my car.

Of course this is just an illusion, this type of illusive time dilation can be removed by calculation, or merely placing an observer to the side (communication orthogonal to motion) :

OB1 OB2-> OB3
O–B--3

While OB1 sees OB2 time rate as slower since OB1 is moving away and OB2 sees OB1’s time rate as being slower for the same reason, OB3 can see the time rate of OB-1 and OB2 without this distortion from Doppler time distortion.
The 3 observers can sync their clocks and it is easy for OB3 and OB2 to see which is experiencing the fastest and slowest time.
They can’t disagree like OB1 and OB2 because they are very close to each other, and could in an instant enter the same reference frame, if both saw the other as having time move more slowly then both sees the clock on the other as being behind their own even when in a moment they can enter the same frame they must agree on reality then.

Could seconds, minutes or years worth of frozen time suddenly unfold in an instant so their clocks match? This would be totally insane and unsupported.

Clearly OB2 and OB3 could agree on which experiences the fastest time rate, this would allow for a discovery of a preffered frame of reference where time moves fastest, but this is not allowed by Special Relativity.

That would be an aether (ether) model.

Indeed if OB2 was orbiting OB3 at near the speed of light, they would be precisely the same distance apart forever, Special Relativity would argue that each should see time on the other almost stop entirely, centuries could pass from the perspective of one observer while only seconds would have passed for the other, and both observers would consider that that they had experienced centuries while the other had not moved.

Clearly none of this could possibly happen, twin paradox indeed.

The world we like in sadly has more respect for the status quo than it has a love for the truth. Intellectual dishonesty and zealot are the name of the game.

My God! He’s solved it! Nobel Prize awaits!

(that, or mod action. it’s a fine line.)

First off Obligatory XKCD.

Secondly, the constancy of the speed of light and time dilation are actual observed things, the former before special relativity was even proposed (and was one of the things that SR was designed to explain). Declaring that they can’t happen due to some thought experiment is meaningless when they actually do happen in the ruler-and-stopwatch world.

Laughed.

O B-have

Relativity has been proved experimentally. GPS is designed to account for the time dilation experienced by the fast-moving satellites (vs. stationary receivers). If time dilation weren’t real, GPS would have had to have been designed differently.

Exactly. Since time dilation is factored into GPS, if there were no time dilation, GPS would not be accurate.

An explanation as to why SR is wrong without a single equation?

A little learning is a dangerous thing.

“That doesn’t make sense to me, it must be wrong.” At least it’s Einstein today and not 9/11 or evolution.

And no learning is even more dangerous. See OP for example.

xkcd is great and it’s awesome when you can apply the comic this perfectly, lol

mythoughts: you know that Special Relativity isn’t a new proposal, but rather a century old now, right? And that lots of people have had time to examine it carefully. I mean, what are the odds that tens of thousands of people – many of whom spent their entire adult lives thinking about these things --are wrong and you are right? Do you really think that you are that special?
Everybody has trouble with Relativity the first time around.
Maybe here’s where you’re missing

Is it really that easy? How do they sync their clocks, given that one is moving past the other? Remember, the only way they can talk to each other is by sending messages using light waves. Find a website that goes through this in detail, or try and work it out yourself, but the gist of it is that because of the time it takes for a message to reach the other, and the time and space dialation, they can’t in fact agree on whose clock is running fast. Observer Two will say that Three’s clock is slow, but Observer Three will say Two’s clock is slow.

No they couldn’t enter the same reference frame in an ‘instant’. One of them would need to drastically change their velocity (in other words accelerate). And acceleration is NOT relative; they’d both agree who was accelerating and that the acceleration screwed up the clocks (another part of Special Relativity).

Indeed, it is a common myth that the “paradox” part of the twin paradox is that one twin is younger than the other. This is not actually a paradox, just a prediction of what would happen (and a more-or-less experimentally verified one, just with very accurate clocks and small dilations instead of twins and space travel).

The actual paradox is that from the point of view of the rocket-having twin, he is standing still and his brother (along with the planet) is the one doing the traveling, so why isn’t he the younger one? The resolution of the paradox is essentially “acceleration matters”.

If te OP had said in the thread title “Why SR could be wrong…” I would be a bit dubious, but since he specifically said “Why SR is wrong…” I don’t see how you Einsteiners have a leg to stand on. Relatively speaking.

E=m(HEY LOOK THERE’S A SQUIRREL)squared

No, that’s a round pig in a squirrel hole.

Help me OB1, you’re my only hope.

It is exactly the problem that two observers in two reference frames cannot agree on what time their clocks show or at what rate the clocks are traveling. They cannot do this until they match reference frames and compare clocks.

So yes, the twin heading to Alpha Centauri at 90% of the speed of light can absolutely look back at his twin on Earth and conclude that his twin is blasting off into the aether at 90% of the speed of light (along with the Sun and the rest of the Galaxy), while his rocket ship has managed–with frantic acceleration–to slow itself down to a stop.

The point of relativity is that neither twin has a privileged reference frame and when they argue about who is moving and who is staying still we can say that both are right, or both are wrong, or that the question is unanswerable.

We zip around the Sun once a year. So when we look at radiation traveling towards us in our direction of travel, is it going faster? No, it is going at c. When we look at radiation traveling towards us from behind our direction of travel, is it going slower? No, it is still traveling at c.

If we had a spaceship traveling from Earth to Alpha Centauri at 99% of c, and that spaceship turned on its headlights, how fast would the light from the headlights be traveling? c. How fast would the light from the tail-lights be traveling? Also c.

All observers would agree that light from the headlights and tailights are traveling at the same speed. A guy on the spaceship would say the light is moving at c. A guy on Pluto watching as if flies by would agree. A guy on Earth looking from behind would agree. A guy on Alpha Centauri looking from ahead would agree.

This fact has been confirmed by observation after observation. We know this effect occurs. And yes, it means that for all these observations to be true that time and space have to bend and stretch like taffy all so one little photon travels at the same speed regardless of where the observers are or what reference frame they are traveling in. Yes, this is a distressing result that hurts a lot of people’s feelings and doesn’t conform to our common sense idea of how the universe is supposed to work. The problem is, that this appears to be how the universe actually, in fact, does work, and our common sense is wrong.
