Gravity & Time: Is Time Different at 17000 MPH?

In summary, according to special relativity, a clock on a satellite moving at 17000 miles per hour relative to the Earth will appear to run slower to an observer on Earth. Additionally, general relativity states that the clock will also be slightly faster due to the weaker gravity in space. However, the overall effect is that the clock on the satellite will gradually lose time compared to an Earthbound clock. This has been experimentally verified and is a well-studied phenomenon by experts such as Dr. Neil Ashby of the University of Colorado.

Say I'm near the Earth and traveling at 17000 mile per hour. Relative to my local time, is it earlier or later on earth? Or is it the same time?

Hi Mr Peanut! :smile:

("earlier" or "later" is irrelevant ; the question is whether clocks are slower or faster)

Special relativity says that you measure an Earth clock as going slow, and we on Earth measure your clock as going equally slow.

General relativity adds that, whatever your speed, your clock will be slightly faster than it would otherwise be, because of the weaker gravity where you are.

According to SRT your satellite onboard clock will run more slowly than an earthbound clock. I believe that this slowing down exceeds the difference in clock rates attributable to the earthbound clock's location deeper in the Earth's gravitational field. This being the case, the net result would be that the satellite clock gradually loses time compared to the earthbound clock. I think that this may have been experimentally verified. Dr. Neil Ashby, University of Colorado, would be an authority. He has done extensive GRT analysis for the Global Positioning folks.
 

FAQ: Gravity & Time: Is Time Different at 17000 MPH?

How does gravity affect the passage of time?

According to Einstein's theory of relativity, gravity can cause time to pass at different rates in different locations. The closer an object is to a source of gravity, the slower time will pass for that object compared to an object further away.

How is time affected by high speeds such as 17000 MPH?

At high speeds, time dilation occurs due to the effects of velocity on space and time. This means that time will pass slower for an object moving at a high speed compared to a stationary object.

Is time really different while traveling at 17000 MPH?

Yes, time is different at high speeds such as 17000 MPH. This phenomenon has been proven through various experiments and is a fundamental concept in physics.

How does the theory of relativity explain the relationship between gravity and time?

The theory of relativity explains that gravity is not a force between masses, but rather a curvature of space and time caused by the presence of mass. This curvature affects how time passes and can cause it to vary in different locations.

Can we physically experience the effects of time dilation at 17000 MPH?

Yes, astronauts traveling at high speeds in space have experienced time dilation firsthand. For example, astronauts on the International Space Station experience time at a slightly slower rate than people on Earth due to the station's high speed and proximity to Earth's gravitational field.
