Somebody had an idea, built up a theory, and started publishing it!
There is no maximum number, and "nebular theory" has been knocked for a loop by the recent discoveries of 400+ "extra-solar planets" - planets orbiting other stars. Classical theories predicted that planetary systems would be rare; however, it seems that every nearby star we've looked at recently has been discovered to have planets - LOTS of planets.
The theory of an asteroid named Orpheus will hit Earth and destroy civilization in the future years. The asteroid is predicted to hit Mexico. Don't be afraid because it may or may not happen :)
The Ptolemaic theory of the planets lasted 1400 years, and it lasted so long because it was not very wrong. But when Galileo discovered all the phases of Venus, the theory's days were numbered. This did not happen until Galileo came along with his telescope to study the night sky.
It is a theory of mentalist
The big bang theory does not actually begin with a "violent explosion." Instead, there was neither medium, light, nor sound in the initial moments. Instead, there was just a rapidly expanding ripple of rapidly cooling energy contained within a bubble of space-time. Eventually matter synthesized from this energy, crystallizing into hydrogen gas through which electromagnetic radiation could permeate. This radiation has been detected as the cosmic microwave background, or CMB. About that time the universe would have rung like a bell as sound energy would have propagated through it. We have detected sound waves bleeding energy off stars within sufficiently dense nebular, so we know this phenomenon is real, and interesting.
