Discussion Overview

The discussion revolves around the concept of time dilation as it relates to different planets and their gravitational effects on time perception. Participants explore how the gravitational force of a planet might influence the passage of time compared to Earth, referencing both general relativity and the specifics of planetary years.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant suggests that a "year" on a planet is defined by its orbital period around its sun, implying that the time experienced on Earth would depend on that duration.
  • Another participant introduces the idea that gravitational effects could influence time, suggesting that stronger gravity might lead to slower passage of time compared to Earth.
  • There is a mention of the complexity of understanding gravitational effects, with a call for clearer communication in the discussion.
  • A participant notes that the relationship between mass, gravity, and time dilation is not straightforward, indicating that a more massive planet could have less gravitational pull if its density is low.
  • General relativity is referenced, with the assertion that time runs faster in areas of lower gravity, such as interstellar space, compared to the Earth's surface.
  • Gravitational time dilation has been empirically measured, with a specific example provided regarding experiments conducted on Earth.

Areas of Agreement / Disagreement

Participants express differing views on the relationship between gravity and time dilation, with some emphasizing the role of gravitational strength while others focus on the specifics of planetary characteristics. The discussion remains unresolved with multiple competing perspectives on how time is affected by gravity.

Contextual Notes

Participants have not fully clarified assumptions regarding the definitions of time and gravity, nor have they resolved the mathematical implications of their claims about time dilation across different planetary environments.

in my book i think that on any planet if we can stay for 1 year then on Earth how much time are gone

What?

A "year" on a given planet is the length of time it takes that planet to complete one rotation around its sun. We would need to know the length of the year on that planet to answer your question. This has nothing to do with relativity.
 


but i think that there is much gravitation then erth then any effect in our time

It is extremely hard to understand what you are saying. Could you take a little more time to type out your posts or get someone to help you translate?

Anyways, the difference in time dilation between a planet and Earth depends entirely upon the force of gravity at the surface of the planet. Even a planet that is 2x as massive as the Earth might have less gravity and less time dilation at the surface compared to Earth if the density is low enough. In any case, the difference is very very small.
 


but because of huge gravitation a spacetime can bend or twist. I think that because of this time can slower then the earth. Simple.

General relativity describes all gravitational fields (not just extremely strong ones) as curvature of spacetime.

Time runs faster in interstellar space, for example, than on the Earth's surface. To find a place where it ran slower, you'd have to go into a deeper gravity well, e.g., near the sun.

Gravitational time dilation has been measured between different heights on the earth: http://en.wikipedia.org/wiki/Pound-Rebka_experiment
