Gravity affecting time?

Question

I'm a bit confused about how gravity affects time. If gravity does affect time, does that mean all time calculations are relative to the Earth?

If I remember correctly, Einstein used electrical chronometers to conduct this experiment. So couldn't one say the reason why stronger gravitational field affects time(or really these electrical chronometers) is because it required more force for electrons to move through the circuit since they have mass?

I'm sure this is wrong as there are other crucial factors to consider, and I hope someone could provide a clearer answer to this topic.

What I meant in the second paragraph was gravity affects the electronic devices because it has electrons and thus differences appear. So the time was actually the same, but the reading/recording of the time on these devices were different because electrons in one was exposed to stronger gravity.As a result, it slowed the electrons down since more force(F=mg) is applied on them.

Answer 1

Gravity affects time directly, not the systems used to measure it. It doesn't matter what time measurement method you use. There is a good explanation of this in Stephen Hawking's book "A Briefer History of Time", chapter 6, pages 46-47.

Answer 2

I actually had a similair discussion with one of my friends rectently. I think it's the other way around. Only time affects gravity. WIthout the forward progression of time, gravity can not be carried out. But gravity does have an affect on time to a certain extent. It is almost two o' clock where I live right now, and I cannot think clearly, sorry.(coincidentally I ended up talking about time again. How strange)

Answer 3

actually, there is a popular stance that "gravity" does not really exist. what we refer to gravity is simple natural attraction of atomic particles. everything has "gravity" since the formula for gravity is merely the mass1 times mass2 times the universal gravitation constent divided by the distance squared. the alternate idea is that the 3 primary dimensions which we refer to as space are seperate from the dimension of time, and when they interact it forms the dimension of space/time, wich is the piont of existence that we live in. when a large mass existes it displaces space/time and causes a warping of the dimensions, thus altering time and even properties of energy. some say that a black hole is nothing more than the colapsing of space/time on a large scale, thus why nothing can exist near one, and nothing can escape one.

Answer 4

frequently relativity, the effect of gravitation are ascribed to the curvature of spacetime, instead of being a rigidity. Simplistically, those curvatures reason a unfastened falling merchandise to deviate from its geodesic [that's the theory of a "at present day line" to curved spacetime; i.e. the international line of particle unfastened from all exterior rigidity is a definite kind of geodesic]. the region is analogous to placing a bowling ball on a mattress; the heavy ball depresses a close-by area of the mattress's floor. in case then you definitely roll a marble for the duration of this "melancholy" it feels the curvature created via the large physique. The marble thrown onto the mattress strikes in direction of the bowling ball. via fact its action isn't alongside a line and its velocity alterations, the marble is now accelerating. subsequently it is not significant no rely if easy has mass to ensure that it to "bend". Now, onto your question. in case you seem at gravitation as a effect of spacetime curvatures and not a rigidity, you will comprehend that easy can impression a gravitational field via fact it possesses momentum and potential [via the equation: E^2 = m^2c^4 + p^2c^2]. they're in all likelihood no longer the only motives, even nevertheless. Edit: i replaced into incorrect, which i found out after examining the above posts. thank you for the question besides, made me study slightly.
