Hmm. In a situation of two ships (A, B) moving directly away from each other at 100km/s such that the relative velocity they ascribe to each other is 200km/s, then there can be no other frame where the ships may appear at rest. As such all frames must assign the 200km/s relative velocity between...
No such thing? At best it's impractically provable. By this I mean you could create an unconductable experiment that in theory would work, but is unlikely to be actualised without significant developments in spacetravel. Take two clocks. A and B. Place them anywhere in the universe, and attempt...
One thing I've failed to get clear is why locality meant additive (25+25 and 30+30) while non-locality was "proven" by the sinusidol wave results. Given the results, anything local must explain why the results are sinusidal. Yet in the proof, the callibration, which is purely local, does indeed...
I don't agree with everything the defenders of Relativity have to say about every detail, but at least I've grasped what they're defending. You, on the otherhand, apparently have no clue what the Special Theory of Relativity even says. If you did, you would know Proper Time is the same for...
Special Relativity provides maths that demonstrates how proper time is always 1/1 for any observer within their frame of reference. It also shows how that observer will look at other observers and say that their time is less than 1/1. These observers will be looking back at him observing that...
The equations are for working out what observers would observe during the period of constant "relative" velocity. During this period both observers describe the other as moving slower through time and having contracted length.
I have no reason, at this time, to consider that absolute velocity...
The value of S never equals S' at the same instant. Only the observered relationship is equal. For v=2/3 c, when S is 1, S' is 0.746 (according to observer S). When S' is 1s, S is 0.746 (according to observer S'). You have to pay attention to who is looking at what. And when.
Galaxies, the...
t>t' and t'>t. This is the whole point of SR and Lorentz symmetry: t>t' for the unprimed observer and t'>t for the primed observer. Each sees the other's time as passing slower. The symmetry only disappears when clocks get reunited, and even then it depends on how they are brought back together...
When c=300000 and v=200000 then y=1.342 and 1/y=0.745 (this the sqr rt(1-(v/c)^2).
When the time for the unprimed observer is 1s, then the time for the primed observer, according to the unprimed observer at that instant, is t'=t√1-(v/c)^2. t'=0.745. When t' is 1s then the time in the unprimed...
From the top:
You should go find out what they mean then reread my post 34.
Tau IS proper time.
The two equations are not the same thing. They tell you two different pieces of information.
The first equation will tell you the time in the primed frame - the one with the ' - at the...
The only reciprocal is from the calculation of gamma. 1/sqr rt(1-(v/c)^2). Since t' = t/gamma, then the equation can be written as t.sqr rt(1-(v/c)^2)/1. The division by 1 is obviously redundant and is eliminated.
You need to understand that there are equations for telling us all sorts of...
In a standford lecture on SR by Leonard Susskind, he explained it that Einstien chose to assume Maxwell was right about the speed of light being a fundamental part of the EM equations and therefore Galilean additive velocities needed to be modified.
Thanks. Bit of a fingerful to type.
That's a big leap from implications to suggesting either can cause the other... How exactly do you suggest a photon might cause time dilation? Special Relativity, on the otherhand, well covers how time dilation... Lorentz symmety causes invariant c. And...
You have written the Lorentz equation wrong. The wikipedia page on Lorentz Factors states it as t'=yt. Written like this the two equations are completely identical.
That view seems backward. In the current model spacetime predates matter. And the invariance of c is only possible due to time dilation and length contraction. Eesh, anyone know a shorthand for that? How about "the phenomenon"?
