Yes, because physics is a science of nature which is based on the experiment and observation. All we can do is created the best theory to predict things and making the module which is suited the theory. If the result came from the observation is diferrent from the module then we will have to...
Maybe I have to explain my paradox a little bit more.
According to RT, or GR to be exact, matters will be dragged in a black hole. During the period, that matter will accelarate like the stone which is dragged into the centre of the Earth. Clearly what has happened to the stone in the Earth...
To my sollution,yes, it's right.However, that's not my point.
My point is what's happened to a matter in a gravitational field without contact with anything. Assume that the space it's vacuum and rotating.Will it become an endless satelite or it has to stop at the centre of the gravitational...
Imagine a crazy engineer digs a very long tunnel through the centre of the Earth.he drops a stone in one end and make a phone to his partner at the other end of the tunnel.Will that man receive the stone?.If there is no man at the other end of the tunnel( suggesting the stone does travel through...
You see,rtt.that's why Janus said you don't understand.Both of the alien's telecopes are in the rocket'stime frame.how can you expect them to be different.
Mind you, we are talking about the case when the racket move so fast that the clock on the rocket slow down to the half rate compared with the clock on the train.therefore lvl>lUl, and even when v=-u, they can be equal to c.

like fredrik suggested, i think you should find some threads that have the similar question like you.I myself found it's very intersting and useful in "is age relative" or "paradoxes".we have a lot of discussions and problems there
When you suggest this question(or paradox in your opinion) did you think about the relative speed between the Earth, the rocket and the train.In SR, i don't think it is right when you just simply add the relative speed of the rocket to the train and the relative speed of the train to the Earth...
I think there is some thing wrong with that.
There are 3 versions of the expansion of the Universe according to Friedmann.1 of them states that we begin with Big BAng and finish with Big Crunch.Therefore, we definitely have the limit of the expansion(if the theory is right.)
hadeka: I have to say that I, or even us have no idea about the parallel universe.What we have is just a theory that suggesting about the possibility to have a universe which you and me have the same identical twin who completely the same like us.They are created by the same structures, same...
Your problem is you continue to asume that Vbc=Vdc, that lead you to the wrong answer.
First, you should find the current for the whole circuits, you can divide the circuits into parts .Then you can find the pottential of each part, then you can find the current of each resistance, then you...
By the way i have a question about the speed of light too.
I have been told that the speed of light is not constant, actually is becoming faster and faster. Is that true? and if it's true, what's the effect of that to the relativity theory? can it be any thing relative to the speed of the...
