Hi makc it's like saying we can't prove that cyanide kills because there is always some % of admixture in it. A good analogy, but there is a difference here. It can be proven that acceleration dilates time if two atomic clocks and a centrifuge are used because the velocity would be negligible but as...

Hi Harry

All I am saying is that there is no 100% proof that velocity causes time dilation because all time dilation experiments involve an element of acceleration and it may be that it is purely the acceleration that causes the time dilation and not the relativistic velocity.

ckam yep, unstable particles running in circles at near-light speed tend to live longer than their friends at rest. Nereid once claimed that you yourself can make this experiment at home using cosmic rays. edit: I have just noticed "acceleration" in your post. well, circles have to go, but...

Hi all

Is there any proof that velocity causes time to dilate? In other words has there ever been an experiment on time dilation where no acceleration is involved?

Tony

The only limitation on the relative velocity reachable is physics as we understand at the moment. The way we view both space and time which IMHO needs to change if we are ever going to be able to really explore the Universe.
If that change ever comes in my lifetime I will be very surprised.
