Topic: Tidal Friction


  
  Pierre-Simon Laplace - Wikipedia, the free encyclopedia
The subject is one of great difficulty, and though it seems certain that the solar system has a common origin, there are various features which appear almost inexplicable on the nebular hypothesis as enunciated by Laplace.
Probably the best modern opinion inclines to the view that nebular condensation, meteoric condensation, tidal friction, and possibly other causes as yet unsuggested, have all played their part in the evolution of the system.
The idea of the nebular hypothesis had been outlined by Kant in 1755, and he had also suggested meteoric aggregations and tidal friction as causes affecting the formation of the solar system: it is probable that Laplace was not aware of this.

 The Earth-Moon System
The scientist who wrote the Encyclopedia Britannica article on tidal friction wrote that, “The mutual attraction between the Moon and the material in the [tidal] bulge tends to accelerate the Moon in its orbit…” To accelerate in this case means to increase the velocity.
In addition, the tidal bulge in the past would have been much larger than at present since the moon was much closer.
The point to this argument is that the fast rotation of the early Earth weakens the tidal acceleration of the Moon, whereas most creationist arguments assume the opposite, that it would strengthen tidal acceleration.

 Laplace, Pierre Simon de (1749-1827)
This work was important because it translated the geometrical study of mechanics used by Isaac Newton to one based on calculus.
In Mécanique Céleste, Laplace proved the dynamical stability of the Solar System (with tidal friction ignored) on short timescales.
Over long periods, however, this assertion has proven false because of the effects of chaos.

 Mercury
As the moon is locked with one side to the earth, its primary, so, and for the same reason, Mercury was thought to be locked permanently with one side to its primary, the sun.
It was estimated that when the planet was in the process of formation, the sun must have caused in it tides, and this, in turn, must have exerted a tidal friction, and breaking of axial rotation.
This view conflicts with both standard alternatives—of nebular and of tidal theories of the origin of the planetary family and with the assumption that the planets occupy the same orbits since billions of years.

 Chapter  4 THE AGE OF THE EARTH   (Site not responding. Last check: 2007-11-01)
Scientists have discovered two interesting facts: (1) the moon is already far too close to the earth, and (2) it is gradually moving farther away from us.
Due to tidal friction, the moon is slowly spiraling outward away from planet earth!
Based on the rate at which the moon is receding from us, the earth and the moon cannot be very old.

[The heat from the tidal friction required to cancel the destabilizing torques in the "stack" would have at least sterilized the biosphere, which never happened; but Talbott never deals with this "side effect" when he mentions the restorative tendency of tidal friction.] Mr.
Cochrane deludes himself if he actually believes there is any chance for Velikovsky to be vindicated on this score [or that "Saturnism" represents any valid "fundamental paradigm shift"].

Large scale movements of water and changes in the atmosphere affect the Earth’s angular momentum.
Tidal friction from the moon, which results in the rise of tides in the ocean, diminishes the speed of rotation.
Physical processes occurring on or within the Earth also affect the earth’s rotation.

Observationally, the Moon is well suited for this purpose because of its fast apparent motion on the celestial sphere.
However, the computation of its ephemerides is difficult and requires the knowledge of some physical constants (like for instance the flattening of Earth's figure and the tidal friction).
