Try the following. Buy cheap watches. Be sure they have new batteries and set all of them (at least five) at the same time in a room set at 70 degrees. Have them working in the same room for a week to check that they work fine and no variation in timing is observed. Then, put one of them inside the freezer compartment.
Next day, compare the timing data of the watch inside the refrigerator with the rest of watches. You will notice that the one exposed to cold temperatures will suffer a delay of 6 seconds (this is the average amount of seconds shown in one of the already made experiments; this timing variation might be different with your watches). On the second day, the same 6 seconds delay will be shown, and so forth for the next days. It will be a "regular" period of delay every day.
Remove the watch from inside the freezer compartment of the refrigerator and replace it by a second watch. You will observe the same timing variation (6 seconds) in this watch when compared to the rest of watches located in the other room.
The lunatic will say that time dilates with cold weather, but you know that such claim is a complete stupidity. The cause of such regular 6 seconds delay is caused by the change of environment to which the watch is exposed.
The same "regular timing dilatation" is observed in every atomic clock exposed to a different environment other than the one where they were calibrated in their manufacturing. It is not that "time dilates" but that the clock itself simply suffers of malfunction.
Notice that the claim about atomic clocks is that they have been tested against temperature and pressure, but, they have never been tested against acceleration, as an example. And notice as well that acceleration must affect the functional work of the atomic clock because the internal mechanism of these clock is by signals perceived by an internal device counting the vibration frequency of the atom of Cesium. When the atomic clock is exposed to lower gravity (notice that pressure and gravity are two separate issues in this case) it is a fact that the behavior of the atom of Casium changes.
The experiments made in the Space Station have proven already without doubt that the behavior of atoms and molecules brought from ground Zero change when taken to outer space, to the point that you can mix liquid metals in outer space, something that you can't do by any means here on ground Zero.
As you can see, you owe me ten million dollars.
You can see as well, that no one in this world will be ever capable to collect the ten million dollars prize by proving that time exists physically.
The entire idea of dilatation of time is a child's fantasy, and the term "space time" is absurd and a mere joke.
