Measuring the one way speed of light.

On one side of the room we have a Wi-Fi transmitter remote control.

On the other side of the room we have two accurate clocks next to each other.

The remote will tell the clocks to start and stop with an elapsed time read out.

We will not move the remote during the experiment.

We now use the remote to start the clocks.

Now we pick up one clock and walk one mile away and set it down at a pre measured location.

From the remote to the clock in the room to the clock 1 mile away is a line in one direction.

We now use the remote to stop the clocks and get the read outs.

The distance between the clocks is 1 mile, with the read outs we can get the speed of the signal.

Moving one clock one mile won't make a rat's ass and will be within our margin of error "close enough for government work".

Thanks for this, Iben.  Took me down a fascinating rabbit hole.

In the video he says we can't synchronize 2 clocks separated by a distance.

Can you synchronize 2 clocks separated by 36 feet?

You have an axle 36 feet long riding on greased bearings that turns both clocks.

Plus or minus how many attoseconds?

The axle has 3 inch diameter disks on each end with holes in them for a laser on each end to shine

through to advance the clocks read outs. The clocks are identical.

Now we can test the one way speed of light with two synchronized clocks in every direction by turning our Michelson–Morley experiment.

What is the simplest explanation for the failure of the Michelson–Morley experiment?

You are living in the matrix and you aren't moving.
