2.4.5 - Number of the tide waves.

In the current theory, the tides are depicted in accord with the supposed cause, without taking into account of how they develop in reality.

Code proposition: [P0] neutral; [P1] classic theory; [P2] favouring the inductive approach; [P3] inductive approach.


Number of the tide waves: two.

[P1] The Moon attracts the surface waters of the oceans to the west, especially to two regions, which revolve around the Earth, forming two protuberances, or tidal waves, ...

Sublunar point, opposite point.

[P1] .... which tend to keep themselves in the same relation with the position of the Moon, near the two so-called sublunar points; the first on the sublunar meridian, the second on the opposite one.

An image consequence of a supposition.

[P3] In the classical description of the tides, the space and time, on which the cause (attraction) operates, are the same on which the effect (tide wave) manifests itself.

In fact, if the cause was attraction, the effect (the formation of the tidal wave) would be visible almost immediately afterwords.

The image of two tidal waves which are moving westwards, from a meridian to the next, is the logical consequence if you assume gravity is the cause. As long as you don't go check the facts.

The tides seen from the satellites.

[P3] Before going on, let's watch once more the video by NASA, with a different explanation, on the number and directions of the tide waves.

Action and effect.

[P3] Tidal waves are not due to attraction, but to the change in density of water, due to the effect of cumulative dissipative processes.

First, we can understand this by the fact that we cannot apply the normal formula of attraction, to understand the difference between the effect of the Moon and that of the Sun.

We can understand this also if we consider the way in which tidal waves move, within more or less large tidal basins.

As the Earth turns on itself, the water molecules vary their density in different places, within the various basins, as a result of cumulative dissipative processes, due to the movement with respect to the Moon and the Sun.

The deeper the water, the more molecules are involved in the processes, the higher the pressure from molecule to molecule, the faster the speed of the tidal wave within a basin, the larger that basin, as will be seen better in itinerary 6.
