Nicely done, dharma. Maybe you could lend your enthusiastic voice to narrate some of my demonstrations at spoonfedrelativity

@eme456

You asked a good question. According to general relativity, the more gravity you take, the slower time you travel. If the Earth rotate slower or not rotating, there is a difference. But as the general relativity tells you that the speed of Earth going around the sun and the gravity also affect the speed of the time.

Therefore the difference between rotate and stop is less than one second.

I hope I can answer your question.

According to the video, about the first one minute, the video show one photon stand still and going up and down. Another one moving up and down also going to right.

the problem is photon must move with 186282mile per hour.The photon which moves with right dierection have a same rate of up down as the photon that stand still. That means the speed of the upper photon is faster than the lower one. you are wrong then.

the change should be the frequency of the photon not the movement of photon.

@eme456 by a few seconds maybe, and only from someone else's perspective

@cLADYification but be assured, it's true--you can take Einstein's word for it

[cLADYification]

waow, i lost it at the first second

[eme456]

Does this mean that if the earth was not rotating at 1000 miles per hour with is its basic rotational speed, and instead not rotating at all, then we would live shorter lives?

you have a sexy voice lollolo

In other words if Jane and Joe see a car take off and they agree its speed is constant however if Jane sees the car traveled 20ft in a second but Joe sees the car traveled 30 feet in a second then what they call a second doesn't represent the same duration of time for each of them. Joe's second is longer.

I am struggling with this but is this what is happening?

[lamrof]

Let's assume it takes a second to take the light to bounce back. Both the moving and stationary perspectives observe it takes a second for the light to bounce on the moving clock. The difference comes in the duration of time represented in a second. A second represents a longer period of time to the stationary observer, because of the longer distance travel observed at a given constant velocity. Is that a correct understanding?
