Discussion Overview

The discussion centers around the relationship between gravity and the passage of time, particularly whether time moves faster in low gravity fields. Participants explore concepts related to gravitational time dilation, the twin paradox, and the implications of extreme gravitational conditions.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant suggests that if time slows down in higher gravitational fields, then in extremely low gravity, time might move infinitely fast, raising questions about the implications of such a scenario.
  • Another participant discusses the twin paradox, emphasizing that while clocks may measure different amounts of time, time itself passes normally for both observers, referencing Lorentz Transformations as relevant to relativistic effects.
  • There is a repeated assertion that time would not be infinite in low gravity, with participants arguing that time would remain "normal" and not subject to dilation, referencing equations to support this view.
  • One participant expresses uncertainty about the implications of the equations and acknowledges a tendency to overlook them, indicating a personal struggle with the mathematical aspects of the discussion.

Areas of Agreement / Disagreement

Participants express disagreement regarding the nature of time in low gravity fields, with some proposing that time could move infinitely fast while others assert that time remains normal. The discussion does not reach a consensus on this topic.

Contextual Notes

Participants reference equations related to gravitational time dilation and the twin paradox, but there is uncertainty about the conditions under which these equations apply, particularly regarding the definitions of "normal" time and the implications of relativistic effects.

I read on wikipedia that time goes slower in higher gravitational fields,

I also know that 'inside' a black hole time stands still.
(simplified, I know)

Does this mean that in places where the gravitational field is extremely low (far apart from galaxies and any other objects having mass) time goes infinitely fast?

So that if you would travel through such a place and the only gravity that wouldn't be neglectable is the one formed by your own mass and thus time proceeds extremely fast there?

just asking,

The right to think about, I guess, it's that when you are here or here, you measure some time.

Every observer has some rules and some clocks to measure time.

Now suppose the twin paradox. The thing that actually happens is that their clocks will not measure the same amount of time, but time will pass as usual for both

The reason of this, it's the Lorentz Transformations, which are the ones you should use when relativistic effects are not negligible. this is, when speeds are not small when compared to the speed of light in vacuum, and when the distances traveled are long enough (I'm sorry but i do not know what long enough actually means in this context, but think about astronomical scale of course)

I thought that the 'solution' to the twin paradox was that first the traveling twin was traveling away from his Earth'sick brother with two different reference frames, but traveling back he travels in a third reference frame, one that is the inverse of his first one, eliminating any gain or lose in time made...

-> what is the difference between time passing by and measure it's progress?
-> the Lorenz transformations apply to the length of the moving object, not to the distance traveled
-> suppose for simplicity of argument that the speed indeed is nowhere near the speed of light, say the speed of sound or something...

No, time would not be infinite. It would be "normal" time (no time dilation). Just let r go to infinity in the equation and you will see that time is not changed.

For some reason I always forget to check the equations :s.

It would have been cool though :)

ps: in the formula on wikipedia
http://en.wikipedia.org/wiki/Gravitational_time_dilation#Outside_a_non-rotating_sphere
you can also set M to 0, same result (obviously)...
