1.   Another clue is tidal forces and the atmosphere.

2.   Any orbital eccentricity produced by the collapse must have been subsequently removed by tidal forces.

3.   As such a singularity is approached, some physical quantities diverge and all observers feel unbounded tidal forces.

4.   Its relationship both to the Gaussian curvature of two-dimensional surfaces and to tidal forces is discussed.

5.   Moreover, as their separation increases, tidal forces will also cause m to slow down to maintain its synchronous rotation.

6.   There is therefore a fundamental link between the curvature of space-time and the existence of classical tidal forces.

7.   Thus, tidal forces can lead to synchronous rotation.

8.   Ultimately there is a direct contest between internal gravity and the tidal forces.

9.   Very few science fiction stories picture humanity as a passive species,allowing the tidal forces of nature to flow unperturbed.

10.   This proposal was readily dismissed by geophysicists who were easily able to demonstrate that the Earth is far too strong to be deformed by such tidal forces.
