Then there is a similar example when I was trying to figure out what length contraction and time dilation would mean for the universe. Single clock on a train, and two clocks on a platform. When the clock on the train is at the first clock on the platform let's say they both show zero, and the...
How about look at it simply, take 4 clocks, 2 in a stationary FOR, 2 in a moving FOR. Let's put these clocks on a train and a platform. One on left side of train one on right, one on left side of platform, one on right. In the platform's FOR, the train and the platform are the same length, the...
Lets say we have a couple objects, one very close to a black hole, one a little farther out and then one a good distance away. Would the one very close to the black hole see the other ones time moving much quicker than their own time? How about just as they are going to hit the event horizon...
You are correct this is more of what I was asking, same with AT. My questions aren't so much about getting a specific numbers but understanding what explains how gravity slow's down time and how it works with the consistency of light in these situations.
I am not totally sure what I am trying to ask, but wondering about gravity at the center of a massive object such as the sun, earth, highly massive star. If you look at the time dilation at the center vs the surface or far in space time at the center time is running slowest. Now obviously for...
I am not sure if of exactly what you are wondering. Are you wondering how spacetime changes to account for light being the same speed in inertial frames of reference? Or are you wondering something like this, in an object's frame of reference it's speed is 0, thus light is moving at the speed of...
Think of it like this let's say I am standing on Earth and there is a spaceship moving away from me at .9c. In Earth's frame of reference light is moving .1c away from the ship in the same direction of it's motion. While in the ships frame of reference that light is moving away from it at c, and...
There is no absolute frame of reference. This is a fact. the speed of light is constant for all inertial frames of reference, this is also a fact. These are tested and observed.
If you would like to learn about relativity and how the universe works you need to get rid of your preconceived...
Sounds to me like it isn't just simultaneity messing you up but the very basics of relativity.
Lets say there are two people one standing on earth, and another in a spaceship they are moving away from each other at .5c. How fast are they moving and with respect to what? How fast will each see...
Ok so you sync they clocks on the train( in the trains frame of reference), then when the lightning flashes hit the clocks stop, you go and read the clocks, they read different times.
Draw out what you are trying to do, start with them both moving away from a mid point at .8c. Then switch to a different frame of reference, and take note of the speed of light and where the light would be.
