##### New Theories / Re: Testing simultaneity and measuring the speed of light.

**Today**at 21:28:19" If I move a clock at 0.5c the same distance d in two seconds, the clock will tick at 87% of its rest ticking rate throughout the move, so it will lag the other by 2x0.13 of a second which is 0.26 of a second. In both cases the clock has moved d, but the lag is not the same."

Thanks.

Can you do that for a few more speeds and then plot a graph of "error in clock" vs speed of travel.

Then, we can extrapolate and see what the error is in the limit of zero speed.

If, as I suspect, it turns out to be zero then; for the very odd case of a very simple, slow, system, we can show that the error in the clock synchronisation is smaller than we need to worry about.

so that gives us two clocks that were synchronised and which now have a small, known phase shift. and which are separated in space which we can then use to time the arival of a flash of light as it gets to each of them.

To an arbitrary accuracy we then know the distance and the time (for this weirdly simple system.

Then we can show (fairly easily by the carts you have been putting before the horse) that it won't work in any more complex system- i.e. anywhere in the real world.
