Einstein's Special Theory of Relativity E=mc2 speed of light
BackThe steps Einstein took to develop his special theory of relativity are as follows: First, Einstein tried to understand what must be implied by the fact that light travels at a speed independent of its source. From this, he realized that time and space are not simply two unrelated concepts; rather, they must be linked in a space-time system whose properties appear most dramatically when objects move very fast and are observed by two different observers moving with respect to one another. His final and greatest step led him to discover and clarify mathematically many new things about the world that are important in each and every frame of reference.
In each and every frame of reference, there are relationships that hold because of the nature of space and time. If space and time were to be reconceived in a new interactive way, then other things, like momentum and energy, had to be reconceived, too. In fact, momentum and energy are linked like space and time.

FizzyBublech, Based on the current understanding of what people think "Time" is, you can think of my reference to "aging rate" and your idea of "time" as the same thing.

"aging rate is altered by velocity" I thought that it wasnt the aging "rate" that changed with motion but Time itself.

if photons dont have mass then how does gravity bend light? you must be mistaken.

Although this may be considered to be time travel, it is not true time travel, as you are not skipping over any period of time, but rather passing through a great length of time at a highly reduced rate of aging. True time travel is achieved by resynchronizing matter (temporal phasing) with states that we only perceive to be of the "past" or the "future" due to the nature in which we, ourselves, experience the fluidity of change within our frame of reference.

Actually, due to "time dialation" effects, time must be passing slower for the particles than for a stationary observer, so I would think that if the particle could see, it would have to appear as though the other particle was moving away at a rate at least as fast as the speed of light, if not faster.

Time, itself, is actually a red herring and does not inherently exist. It is a perception and a system of measurement that we use in an attempt to understand the universe and our perception of it. It is a useful concept, but a barrier to truly understanding the nature of matter and energy. Once it becomes clear what one is actually observing, then the fallacy of time becomes immediately evident and then you can understand how aging rate is altered by velocity. EVERYTHING is relative.

Time is being decieved by a false perception sir. Since there is not a universal perception of time, creating or acting as if there is one would make time an illusion on a universal level. And about the correctness, you got me misinterpreted, I said "OF COURSE NOBODY HAS A CORRECT POINT OF REFERENCE." I still agreed that neither is right universally but both is right depending on perspective. Read carefully what I said, I had no contradictions.

Photons have no mass AT REST.
Photons however, are never at rest... they rtavel at the speed of light, and hence have a certain amount of energy.
Energy and mass are the same thing, ergo photons have mass.

It depends on the reference frame.
To us, on earth, it looks like light takes 8 minutes to reach us. But from the point of view of the light, the woyage is instantaneous.

Illusion: The condition of being deceived by a false perception or belief.
Your use of the word is incorrect. Time is not an illusion.
With regards to correctness, lets say there was another conductor traveling in a train going the opposite direction You are saying that since now there is a 3rd party the correct perspective can be given? Problem is the 3rd conductors perspective is different from the other two, so who is right?
