It SURPRISES me this thread carries on. Two different phenomena are being discussed, and frequently mixed up due to that …
And those tides would happen even if Earth did not spin daily, main cause of "whirlpools", as far as I can understand. I have not delved into the existing lot of local cases, but I´ve seen they are very complex, especially on a very long work of NOAA I can´t find now”.
Long ago when I was a boy, I already realized that, e.g., strongest high tides were always at same time, and when full or new Moon, in Atlantic coast of Spain where I was in summer holiday. And nowadays, just seeing the Moon in Madrid sky at a certain moment, I can tell how high is the tide at mentioned coast, and also if the tide coefficient is high or low, without any complicated maths or any additional information.
How “on Earth” the OP can say:"The gravity of the moon does not reach the Earth”? … (!!!)Has he never had any experience similar to mine?
Are we still asking why the Earth gives itself two tides?
You say “a very long work of NOAA I can´t find now”. Can you describe what it covers as I might have a copy in my lecture notes.
According to the lunar theory of the tides ...
Quote from: Fermer05 on 11/05/2018 16:00:32What is the height of the tidal hill at the equator? You really are missing the point here. The question is not the height of any bulge, but the periodicity of the variation in heights. This periodicity is, as explained previously, the combined effect of Moon and Sun.Please show your calculations to explain spring and neap tides and their exact periodicity.
What is the height of the tidal hill at the equator?
as the planet spins faster than the Moon rotates around it, and both these bodies are "in harmony", maybe the problem of explaining this is how gravity works according to contemporary theory?
I think we're not thinking out-there enough.How do liquids separate from solids, and by what tension of viscosity do liquids act like solids, and under what temperature variations, for instance.....

If you are posting in someone else’s topic and you want to add another comment before someone else has posted, it is polite to modify your last post rather than create a new post. If you disrupt the flow of a thread moderators will remove posts.
in reality the Moon revolving around the Earth, it accelerates that slows down the orbital velocity of the Earth, due to which in the new moon, the orbital velocity of the Earth is maximal, and in the full moon, the minimum....The Moon's role is indirect, creating an uneven orbital velocity of the Earth. The maximum orbital velocity of the earth happens three days after the new moon.The minimum orbital velocity of the earth is three days after the full moon.Once a year, the Earth as close as possible to the Sun (perihelion), while maximizing the Earth's orbital velocity and, as a consequence, the height of the tides increases.
Marking your own answer as the best answer. Wow.

The most sensitive gravimeter, this is a conventional pendulum clock.In the phase of new moon and perihelion, the clock will go fast or slow.

Most of the work deals about the huge variety of local costal tides, but it also has an interesting part analyzing root Moon and Sun related causes of tides.I´ve already said on the other thread that, though they explain the issue in a similar way as me, they even go beyond what I say, because they use the term centrifugal force even for the whole Earth revolving ... ....
It is possible to put a question and so:In the phase of the new moon or full moon, the pendulum clock will go faster.
