... number is about 0.0000000004.4. Note that the units canceled each other out. This can be written in scientific notation as 4.4 X 10-10 or 4.4E-10, both of which are clearer to read. We will use 4.4E-10 because it is easier to type this number style into our calculators. Now that we have figured out ...

History of Solar System formation and evolution hypotheses



Ideas concerning the origin and fate of the world date from the earliest known writings; however, for almost all of that time, there was no attempt to link such theories to the existence of a ""Solar System"", simply because almost no one knew or believed that the Solar System, in the sense we now understand it, existed. The first step towards a theory of Solar System formation was the general acceptance of heliocentrism, the model which placed the Sun at the centre of the system and the Earth in orbit around it. This conception had been gestating for thousands of years, but was only widely accepted by the end of the 17th century. The first recorded use of the term ""Solar System"" dates from 1704.
