Time Dilation

Seen it before, the electro waves from the car radio disturbs the watch, this is fake
He maybe had it at low volume so you couldnt hear it?

EDIT: Nvm last row, the car radio always gets waves so you can hear radio directly when you start the radio, it recieves waves even if its off

This video is fake, he got too much time difference.

"If you plug in numbers for a 48 hour round trip flight at constant speed at the equator, you get -260 ns and 156 ns for the eastbound and westbound flights respectively."

But oh well... I don't think he would measure nanoseconds with that stopper xD Besides I guess he don't feel like driving around for 48h

So is there such thing as time being slowed down when you're in a vehicle?

I personnaly don't belive it.
