AETHER: The Physicalists' God

Not even light can reach the speed of light! For a single photon to reach the speed of light the whole Universe would need to turn into that one photon. Because energy is finite and the speed of light needs to be kept constant for fields to work in the allowable speed range (0 to 300,000 km/s), there is time dilation and space contraction for material systems moving at relativistic speeds. As a photon reaches the speed limit its waves are flattened, it will lose its wavelength (energy) and go back into being Aether. Slow down the system and it reappears... as required by local spacetime conditions.

I'm no expert but I think this is very wrong. Could someone who is an expert confirm/deny this?

I'm no PhD, but I can tell you that light does indeed travel at the speed of light.

In other breaking news, sound travels at the speed of sound, and water is wet.

Any news on the Pope's religion or where bears do it?

We are not sure that light has zero rest mass or that it travels 100% of the speed of light.

But we do know it is very close to it. Make that very very close.

The speed of light is, well, the speed of light. If you think that photon travel at 0.999999999999c where c is the current value of the speed of light, we can just define the "correct" speed of light as c'=0.999999999999c.

If a photon has zero rest mass it may also be an unstable energy unit but without the time to decay for certainly it would have decayed in billions of years of travel if it contained a time component.

As to the light speed.

If a photon has a rest mass particle then it can not attain a speed of C but will only attain a velocity of C ‘ which is slightly less then the theoretical speed of light C.

In this case the measured speed of light is C ’ and the true speed of light C must be calculated or by other means to be known.

The photon must also be a stable energy unit to prevent decay.

*sigh*

:(

You wouldn't have a credible citation for this claim, would you?

Actually I don't think that is accurate. I know that is what the headlines say but if you read the articles it isn't that simple. The light is being absorbed and remitted very slowly in a special medium so its average speed though a medium might be very low, but it is still traveling at speed C between the atoms.

Imagine driving a special car that can only travel at 60mph on a toll road (this car just magically goes 60mph when you step on the gas and stops instantly when you step on the brake). You drive for a while, then have to stop for a toll both, it takes time to pay the toll, then you continue your trip at 60mph. If there were a lot of toll booths; when you finish your trip and calculate your average speed it would be less than 60mph. Your average speed down the road is less than 60mph, but while you were driving you always traveled at 60mph.

Much like any solid!

If it has a rest mass then shouldn't it be able to travel at any speed between 0 and almost C, like say a marble? This does not seem to be the case.

Check out Bose Einstein Condensate slowing down light to rather pedestrian speeds.
Also look at Cerenkov radiation where fast electrons exceed the speed of light in borated water.

A quote from the wiki article speed of light

However, by 1950 repeated measurements by Essen established a result of 299,792.5±1 km/s; this became the value adopted by the 12th General Assembly of the Radio-Scientific Union in 1957. Most subsequent measurements have been consistent with this value.

First, there doesn't seem to be an accurate enough measurement to support this idea even if it were true. Second, the classical nature of light (including its speed) is well understood as a solution to Maxwell's equations. This was confirmed by Hertz's famous experiment. The speed of light is what it is. It depends on the permittivity and permeability of the medium through which it propagates. As an exercise in my EM physics class I solved a simplified version of the PDE. The idea that you can measure electrical properties of space in the lab and calculate 'c' from them blows my mind. The solution is very elegant and beatiful.

Sol Invinctus discussed this there are two components to mass, a photon has zero rest mass.

Why would a photon decay?

If Einstein didn't want people discussing his ideas, why did he publish? Part of his genius was that he made extremely complex and difficult ideas comprehensible to the ordinary intellect. Thinking of these things for the first time was the hard problem. Understanding them afterwards wasn't.

No, actually he didn't - though some coming after him did a not bad job of it. That's why a lot of people "in Physics" freely admit they do not fully understand/follow Einstein or Quantum and the few who do have to use methods that get weird on their own to just attempt to give some people a hint of what is really going on (and as many frauds and fools freely demonstrate for us, the hint is usually missed or misunderstood).


Apologies Cuddles - you beat me to it - I just couldn't let it pass as soon as I saw it!!
