Laplace's nebula theory (1796):it all began from a huge cloud of gas which was spinning slowly. This cloud collapsed under gravity. As it collapsed, it started spinning more quickly and began to flatten to conserve angular momentum. Schmidt-Lyttleton accretion theory (1944):Sun passed through a huge cloud of gas and acquired matter to form planets. Proto-planet Theory:started with a cloud of dust and gas in a state of hypersonic turbulence. Thus, rapid internal collisions took place. This resulted in aggregation of masses at various places Capture Theory:interaction between a condensed solar mass star (SUN) and a protostar of lesser mass. The protostar entered the Roche limit and was disintegrated to form bodies like planets. The Solar Nebula Theory:slowly rotating nebula very similar to the Laplacian theory. The planet formation starts with a disc of 0.01 to 0.1 solar masses. This is also a monistic theory dealing with mass and angular momentum distribution. The Modern Laplacian Theory:started with a cool gas cloud which condensed in such a way that the angular momentum of the central body was only 1 percent of the system. I have noticed in my own research that solar activity is known to influence human consciousness. Solar flares affect the Central Nervous System (stomach lining), all brain activity (including equilibrium), along with human behaviour and all psycho-physiological (mental-emotional-physical) response. Solar flares can cause us to be nervous, anxiousness, worrisome, jittery, dizzy, shaky, irritable, lethargic, exhausted, have short term memory problems and heart palpitations, feel nauseous, queasy, and to have prolonged head pressure and headaches There are two reasons why the Moon (like other moons, and Mercury) has so many craters, and both are related to its lack of an atmosphere.
1) There is no atmosphere to prevent small-to-medium meteors from striking the surface. On Earth, only the largest and densest meteors can make it to the...
