The Einstein Effect: How Einstein Got Relativity Wrong but Discovered Something Else Entirely (Part One)


The Theory of Relativity has practically become a law today in modern physics. New students who go on to take courses that deal with this theory are pretty much told by their teachers that this “theory” has been proven in every case and that it would become a law if we could travel closer to the speed of light to once and for all confirm Albert Einstein’s work. It’s a done deal, now we just have to understand why this wonderful theory doesn't work with the rest of physics. Why doesn't this spherical object (the Theory of Relativity) fit through the square hole of Physics?

I’ll give you a shocking answer to that question. It doesn't work with the rest of physics because the theory isn't correct. Yes, the math is correct and the some of the outcomes too are correct, but when Einstein’s theory is applied to light and light speeds, what the theory really does is explain an effect similar to the Doppler Effect, except with light. This is why I have named it the “Einstein Effect”. I will discuss this effect later in the blog.

Now, if you pull apart Einstein’s theory you will find flaws with it but in order to find those flaws, you have to understand the original theory. So, for the lay people in the audience (and hopefully I am not writing this just for myself), I will break it down to the absolute core in order to bring a simple understanding to this complex theory.

The core of this theory is this; physics is the same everywhere throughout the universe but certain things, like speed and what an object looks like, are relative. By “relative” I mean different from one place in the universe as compared to another place in the universe. Sir Isaac Newton’s law of absolute rest no longer applies as an object that seems to be at rest can now have motion and those in motion can be at rest. For example: a rock sitting on the ground seems to be at rest and under Newton’s laws, it would be. However, relative to someone in the International Space Station orbiting the Earth, the same rock is moving because it is on the Earth and the Earth is rotating on its axis. The speed of an object now depends on where you are observing it from, not from an absolute state of rest. This changes things when you are doing calculations and has deeper implications than I care to get into but I will give you one more example so that you understand.
If you are driving along a road at 55 km per hour and another car comes from behind you at 60 km per hour, with the Theory of Relativity you can say that, “relative to me, that car is going at 5 km per hour” and you would be correct. The 55 km per hour you are driving is relative to the pavement you are driving on (or what Newton would have called “absolute rest”) but the 5 km per hour is relative to the speed of the car passing you. The person in the car passing you could say that, relative to them, your car is moving backwards at 5 km per hour and this too would be acceptable. It is all from your point of view.
Now, I also mentioned that Relativity changes the way an object can look. This has to do with the speed of light and this is where it gets a lot more complicated.
The speed of light which stands at 299, 792, 458 metres per second in a vacuum hasn't been observed going any faster, no matter where it has been observed. In an airplane, in a car, in space, no one has seen the speed of light go faster than 299, 792, 458 metres per second. Light can be slowed down by passing it through objects but it doesn't seem to speed up. Even when the laws of physics demand that it speed up, it still does not do so. For example, if a man on a train is pointing a flashlight in the direction he is travelling and someone standing still next to the train tracks has a device that can measure the speed of light coming from the flashlight, the result should be the speed of light plus the speed of the train. This doesn't happen. The laws of physics don’t seem to fully apply to light.
When Einstein thought of how the speed of light did not increase and he applied it to relativity, he ran into a huge problem. The speed of light has to be able to increase in order for relativity to work properly, so what can he do? Well, he looked at the formula for speed (S=D/T (speed equals distance over time)) and came to the conclusion that if the speed doesn't change and the distance doesn't change, then time must change. That was the only logical solution. Now, instead of light speeding up or slowing down, time sped up or slowed down to accommodate a consistent speed for light to move. Mathematically it worked and after years and years of people running successful experiments, eventually most of the scientific community relented and accepted his theory.
It was this theory that brought us the famous E=mc2 where mass and energy are interchangeable and also helped bring about the Nuclear Age where humans were able to harvest the energy stored in the mass of certain types of material; sometimes for good and sometimes for bad.
Yet this theory doesn't quite fit with the rest of physics. When approaching the speed of light, this theory works great but slow things down to normal everyday speeds and the calculations don’t seem to work as well. The core concept works (remember, everything is relative) but if you look into the actual mathematical calculations involved, they are mind-numbingly complex. They also have a speed limit built into them. This speed limit is 299, 792, 458 metres per second, the same speed as light. You can put numbers into the calculations, but the resulting speed at the end will not be higher than 299, 792, 458 metres per second because as speed increases, so does mass until it reaches infinity at the speed of light!

Why would a theory need a built-in limiter like this and why are people so proud of that fact? It’s like putting a top speed on all speedometers around the world of 100 km per hour and then telling everyone how your theory that cars cannot go faster than 100 km per hour is true.
It is the inconsistencies that brought me to believe that something was wrong with the Theory of Relativity and I will go into this more in my next post.
