Tidal forces between the Earth and the Moon result in the transfer of angular momentum, causing the Moon to gradually move away from the Earth. This phenomenon occurs because the gravitational pull of the Moon creates tides on Earth, which in turn exerts a force back on the Moon. As the Earth rotates, it drags these tidal bulges slightly ahead of the Moon, resulting in a transfer of energy and momentum. This process leads to an increase in the distance between the Earth and the Moon over time. Understanding this relationship is essential for grasping the dynamics of celestial mechanics.

why tide force makes distance between Earth and moon longer?
The problem with that sort of answer is that Wikkers is constantly being slagged off by this Forum as being unreliable. What is an uninformed questioner supposed to do? Surely what is needed here is at least a basically helpful, summative, answer and not just a referral to an outside source.
It might be obvious from the wording of the question that the questioner, here, does not have English as a first language and may need a little gentle help.
Do we even know? My understanding of dark energy is that particles come into existence, exert and outward force, then vanish. My problem with that is how, of course, then how does dark energy know to push everything in the same direction? The pressure exerted would be in all directions, even if the space was moving so why isn't stuff pushed all over the sky?
Thanks - rev
I think it's easist first to watch a short vidio clip
I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way?
The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
