Tidal forces transfer momentum from Earth to the Moon, causing the Moon's orbit to expand.
Is it true that tidal forces transfer momentum from Earth to the Moon, causing the Moon's orbit to expand?
Yes. Multiple studies and precision measurements confirm that tidal forces transfer angular momentum from Earth's rotation to the Moon, causing Earth's rotation to slow down and the Moon's orbit to expand (recede).
Verdict: SUPPORTED · 3 sources for, 0 against · Last checked
The retrieved papers consistently state and build upon the well-established physical principle that tidal interactions between the Earth and the Moon result in the transfer of angular momentum, slowing Earth's rotation and causing the Moon's orbit to expand (recession of the Moon). Papers [0], [1], and [9] explicitly mention this mechanism and its effects. No papers refute the core claim.
