Kinda thought this would get at least ONE reply, geez.
It's probably because a week and a half ago I posted the same thing:
NOTHING EXCEEDED LIGHT SPEED....
and as it says at the bottom... if they could use a real square wave pulse... then the so-called effect should disapear... and not happen...
im not impressed... but it is interesting... since if nothing else, it suggests ways of getting a faster response time from fiber optics.. which do not allow light too travel at light speed... but always less than.
Who told you this? Einstein? You know he only assumed it.. and I have not seen proof it is the "speed limit," only evidence.
dah.... THE ARTICLE SAID AS MUCH....
dont you know... light.. inside a fiber optic... moves much slower than light speed.......
the fact that we can modify it speed in the fiber.... is not such a big deal.
do it in a vacuum... and your will have shattered the basis of relativity.
Nobody has ever heard of the advanced wave solution to Maxwell's wave equation. Right?
Where is James R hiding? Why hasn't he already explained to us how Relativity is so wonderful and we don't need to worry about another paradox?
What would that be?
Maxwell's wave equation is very widely available. The advanced wave solution and the retarded wave solution are very widely discussed in scientific literature. That is what it be.
Well I was just wondering what your point is. I could pull up his equation right now and have no clue what I am looking at... I do not study physics.
Then just go back to sleep and don't worry about things you don't understand.
Anyway I looked up "advanced wave solution" and found about 4 results in Google. However you might be talking about the wave solution I know about... namely the speed of light.
But aren't these equations based on experiment and observation?
When Maxwell wrote his famous "Maxwell's equations", he was collating the experimentally based knowledge obtained by Franklin, Faraday, et al in a mathematical form. In addition, he used the standard, well known physics wave equations and adapted them to electromagnetic terms, and produced his electromagnetic wave equation. The mathematical solution to his equation, being a square root, was both a positive and a negative number. The positive number is commonly called the retarded wave and is the electromagnetic radiation that we all know and love. The negative number is called the advanced wave, and is speculated by a number of theorists to happen PRIOR to the event, such as the jump of an electron in its orbit, which produces the familiar EM.
Some theorists speculate that, as the retarded wave is an expanding wave front which flies away from its parent event, the advanced wave front COLLAPSES upon the parent event, prior, in our normal time perception, to said event.
