at first I was addressing you about you bringing up the year and gps satellites
The duration of the period is not important. What matters is that regardless of what the displays might indicate due to improper calibration for the
conditions, the clocks will experience contemporaneous periodicity.
If a GPS clock is not adjusted for orbit then the clock simply does not keep time accurately. It doesn't matter whether it's running too slowly or too
quickly, it doesn't go off into the future or fall back into the past.
I'm left to wonder what exactly is meant by "change in the rate or flow of time".
First of all im not 100% sure about what im saying
im trying to think about this stuff to its hard for me to grasp but this what I write is my best
attempt at thinking what the deal is.
Ok so its thought all energy was "born" at the same instant, the big bang. this was the beginning of universal time, for the total universal system as
a whole, this was the beginning. From there though every separate part and the macro structures the tiniest parts created were on their own
trajectories, with their own angular momentum, and moment to moment interactions with other quanta in their given regions of space and time. Thus in
order to "keep time", to know a steady rate of passing time, this can only be done relatively. Relative to other things in similar states of rest or
reference frames and constant velocity. After the universe began, what can an observer that arises in the universe use to keep time? They can use a
year, the distance in space and time the earth moves to travel around the sun, this is like those examples of the light clock, a second being the
distance in space and time the particle took to travel between two mirrors. Because Einstein claimed light was a constant (and observations and
experiments backed him up) it was thought to be able to be used as the perfect measuring stick, this is the way im sure the age of the universe was
converted into years. He said (and it seems like it does) light is the fastest speed energy can go at in the universe, and when an interaction takes
place to produce light in space, it is demanded to travel at that fast speed of the speed of light, this means that regardless of what velocity any
observer is traveling, they have to know that the light is consistently traveling the speed it is forced to by nature. So if energy is added to the
system of a light clock (clock with the photon bouncing between two mirrors) to make it go faster, the light clock is traveling more space in less
time (then it was before it accelerated) thus relative to its previous measured position, it is experiencing time in a different manner. this is why
the clocks on board the satellites experience time in a different manner, due to velocity at least. If we added a ton of energy to the earths orbit
to make it revolve around the sun twice as fast as it currently does, would time be speeding up?
Heres my attempt of an example as to why doing more action, in an allotted time, is experiencing a relative duration of time, differently depending on
You have an identical twin in every way, its a clone of you. there are an infinite number of playing cards face down in front of each of you, and you
both can turn one over with the same speed and move onto the next and turn that one over. On average in 20 seconds you and your twin can both turn
over 20 cards. You are both doing this on earth and that is the constant in the experiment. The sun pulses light every second and the experiment is
how many cards can each twin flip over in 20 seconds. The trick is one twin will be doing this at constant earth time (physically possible, rate of
action over an interval of time; 20 cards in 20 seconds), and the other twin will be doing this with the power of the speed of light. Im not good at
math, but in 20 seconds if the earth twin flips over 20, then the speed of light twin can maybe flip over a million or so.
wouldnt you say the twin that can operate at light speed experienced time lapsing in a different manner relative to his twin, and relative to himself
when he was not operating at the velocity of light?
