So your speeds are R+ S vs R- S relative to the sun. So this would affect your "time speed" as observed by someone on the sun. There would be several problems with setting up such an experiment!pokk said:earth rotates around sun @ R speed, Earth spins on its axis @ S speed. Both R & S are counterclockwise. On the equator @ noon my speed is R-S whereas at midnite its R+S. Q= does this affect the time speed thing?
thanx & even though i don't understand u i believe u so I'm contemplating your post...thanxghwellsjr said:Because the surface of the Earth is continually accelerating, as you pointed out, noon and midnite approximate two different inertial frames, but in each one, if you measure the round-trip speed of light, you will get the same value.
Prior to this fact becoming known, this is essentially what the famous Michelson-Morley experiment (MMX) was trying to take advantage of, assuming that the speed difference relative to the sun (or the stars or whatever) would be detectable. But note that the speed difference you are talking about has a direction to it, the North-South component of the speed would be the same at noon and at midnite whereas the East-West component would be different. It would have been extremely difficult to make a precise enough measurement of the East-West component of the speed of light at noon and compare that to the same measurement at midnite, twelve hours later. So instead of doing that, they compared the East-West measurement with the North-South measurement, looking only for a difference in the two. But they could never detect any difference, no matter when they did the measurement, at anytime during the day or night nor at anytime during the year. The North-South component always matched the East-West component, as well as all other directions in between.
So this was the first experimental evidence that the answer to your question is "no".
The relationship between time and speed on Earth is complex and is governed by the laws of physics. Generally, the faster an object is moving, the slower time appears to pass for that object. This is known as time dilation and is a result of Einstein's theory of relativity.
No, time can pass at different rates for different objects on Earth depending on their speed and gravitational pull. For example, a person on a fast-moving airplane will experience time passing slightly slower than someone on the ground due to their higher speed. However, the difference is so minuscule that it is not noticeable in daily life.
Gravity also plays a role in the time-speed relationship on Earth. According to Einstein's theory of general relativity, the closer an object is to a source of gravity, the slower time appears to pass for that object. This is known as gravitational time dilation and has been proven through experiments.
No, the time-speed relationship can vary in different locations on Earth due to factors such as altitude and gravitational pull. For example, time passes slightly faster at higher altitudes due to weaker gravitational pull and the absence of atmospheric drag.
Yes, it is possible to manipulate time on Earth by changing our speed. This is seen in experiments with high-speed particles, where they experience time dilation due to their high velocities. However, the effects are so small that they are not noticeable in everyday life.
