Distance between earth and moon increasing

Click For Summary

Discussion Overview

The discussion revolves around the increasing distance between the Earth and the Moon, exploring the reasons behind this phenomenon. Participants examine various theories and implications related to gravitational interactions, tidal forces, and the long-term fate of the Moon's orbit.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant suggests that the increasing distance may be related to the Earth's orbit and the effects of Newtonian laws, questioning if the Moon's movement towards the Sun contributes to this change.
  • Another participant attributes the increasing distance to tidal interactions between the Earth and the Moon, explaining that the Moon's gravitational pull creates tidal bulges on Earth, which in turn affects the Earth's rotation and transfers angular momentum to the Moon.
  • A different viewpoint mentions the eventual fate of the Moon, suggesting that it will reach a stable orbit and that the Earth will experience significant wobbling before the Moon approaches the Sun at the end of its life.
  • One participant agrees with the theoretical aspects but emphasizes the extensive time frame required for these changes to occur.
  • Another participant elaborates on the dynamics of motion between the Earth and Moon, discussing how the opposing directions of their movements affect tidal forces and angular momentum, and speculating on a stable position for the Moon within the Earth's gravitational influence.

Areas of Agreement / Disagreement

Participants express a range of views regarding the mechanisms behind the increasing distance, with some agreeing on the role of tidal interactions while others introduce different perspectives on the Moon's long-term fate. The discussion remains unresolved with multiple competing theories presented.

Contextual Notes

Some claims rely on assumptions about gravitational interactions and the long-term stability of orbits, which are not fully detailed or agreed upon by all participants. The discussion also touches on complex concepts such as angular momentum and tidal forces without reaching a consensus on their implications.

I learned that the distance betwee the Moon and the Earth is increasing but I couldn't find the reason for it, Is it because of the Earth's orbit? I mean that when the distance is minimum , causes the moon to move towards the sun ( Newtonian laws ) and even when the distance becomes maximum the Earth won't be able to completely recover the effect which had made the distance greater... ? Thankyou for your answers

Its due to tidal interaction between the Earth and Moon.
The moon causes a tidal bulge in the Earth.
The Earth tries to drag this bulge along with its rotatation, while the Moon tries to keep the bulge aligned with itself.

The result of this "tug o war" is that the Earth's rotation slows and the resultant loss of angular momentum is transferred to the Moon, lifting the Moon into a higher orbit.
 
I watched a video about the Moon's fate. Eventually it will reach orbit stability, I believe that's what they said. When that happens our planet will wobble feverishly. Then the moon will eventually meet the Sun when it's near its own end of life.
 
Agreed theoretically, but it will take an astounding amount of time.
 
Thankyou for ur answers I wanted to know if I have understood the task correctly or not:)
the direction of motion of these two heavenly
bodies are totally opposite. This means that the tides on Earth will have a
direction opposite to the earth’s rotation and this causes the Earth to slow
down and in other words it’s angular momentum will decrease where P = m.v
so due to the decrease in v the ‘P’ will decrease or in other words the effect of
gravitons decreases which will cause the moon to feel comfortable to escape
from the gravity and this causes the moon to take a distance form the earth
BUT as we all know the space-time curve of Earth is quite larger than the
moon’s so we can expect a certain position of moon where Earth won’t be
effected by it and the moon will be still inside the curve & that is the point
where the moon would get a stable situation
