Here is one more good simulation for twin paradox.

Lorentz transformation transformation maths a. a change in position or direction of the reference axes in a coordinate system without an alteration in their relative angle b. an equivalent change in an expression or equation resulting from the substitution of one set of variables by another physics ...

http://www.phy.syr.edu/courses/modules/LIGHTCONE/LightClock/#twins I think the animations show really well, that for the light speed to be measured as absolute to every direction, the time can't be absolute, the balls symbolizing light pulses really illustrate it well, as do the light cones, also ne...

These might be a helpful pictures and videos to demonstrate how in twin paradox one is inertial observer and one is inertial observer most of time, but that "turn" breaks the inertia http://www.phy.syr.edu/courses/modules/LIGHTCONE/LightClock/#twins http://www.phy.syr.edu/courses/modules/LIGHTCONE/L...

Thus, although it is eating up my holiday time, I have glanced at the first manuscript you asked me to rerad, and immediately realised that this is the type of manuscript I hate since it gives more credence to mathematics than physics. In other words, the mathematics is not used as a language to in...

i stand corrected. (was misinformed/didn't read). note however, the two clocks here were orbiting at approximately the same altitude as each other, and the difference with earth bound clocks due to GR were approximately the same order of magnitude as the difference(s) due to SR, in this experiment....

so far as satellites are concerned, and in particular the Hafele--Keating experiment (and later verification by NPL and others), i have it on good information (though i have not calculated myself), that the DOMINANT cause of time difference here is due to GR (General Relativity), and the gravitatio...

Thought experiment: You are inside a closed box. Now time is just going at rate t. Now it suddenly goes at rate 1000t. Then it changes to 100t. Then to 10t Then to 50t. And back to t. Now if this would have actually happened, would you have noticed anything strange happening in your reference frame ...

http://en.wikipedia.org/wiki/Lorentz_transformation The Lorentz transformation describes only the transformations in which the spacetime event at the origin is left fixed , so they can be considered as a hyperbolic rotation of Minkowski space. According to wiki also by some logic if you used Lorentz...

Concerning light and time stopping in a Bose Einstein condensate (BEC), this author implies that the light does not stop, it is absorbed and it's characteristics are preserved. When the BEC is prodded to release the light ( stored information) it gives the illusion that a specific photon was stoped...

Lets go from twins to triplets. Triplets are in a gigantic merry-go-around, going in counter-clockwise direction. First they are all in the middle, they synchronize three atomic clocks, and put them in their backpack. One of them, lets call him A stays at the center, other two get bored, and walk a ...

The kinematic change in time must ALWAYS be a decrease in the time of the "moving" clock within the reference frame of the stationary clock; and must thus be negative for both the eastward and westward flights. If I understood correctly, in their calculations it would decrease also if the plane was...

http://en.wikipedia.org/wiki/Twin_paradox This result appears puzzling because each twin sees the other twin as traveling, and so, according to a naive application of time dilation, each should paradoxically find the other to have aged more slowly. In fact, the result is not a paradox in the true se...

So what do you think about these tests where atomic clocks are synchronized and then one of them is flown around? http://en.wikipedia.org/wiki/Hafele%E2%80%93Keating_experiment Based on the result table in the wikipedia, 1971 Hafele-Keating experiment result seems to match predicted values for both ...
