That the sun was the center of the universe
1473.
It was because people that that his calculations were not accurate and also because his calculations of the astronomical positions was not made easy. It was hard to understand
Nicolaus Copernicus came up with the theory that the Sun is the center of the Universe and not the Earth, contrary to the popular belief then. This made him famous.
Contrary to most people of the 14th Century, Copernicus believed that the Earth revolved around the sun. Galileo later proved Copernicus' theory to be correct.
Nicolaus Copernicus discovered that the sun, rather than the earth, was at the center of the universe. His book, On the Revolutions of the Celestial Spheres, was published just before his death in 1543.
The Copernican Theory said that the Sun was the centre of the solar system, not the Earth. The only error he made was that the orbits were perfectly circular. Keplar corrected this by showing the orbits were ellipses.
many people believed that everything revolved around the earth but some believed everything revolved around the sun and now r famous for the unit space for example Corpernicus.
I'm not THAT sure...so...Just a guess here, okay?Copernicus started the whole heliocentric idea. Then, Kepler founded about the eliptical orbits, and famous Galileo published his Dialogue Concerning the Two Chief World Systems.
"Explain this" is actually "You explain this" or some form of that phrase. As such, "You" is the [understood] subject and "explain" is action requested, i.e. the verb. Or another way of saying it is "explain" IS the verb, "explanation" is the noun, as in "You please explain the written explanation to me.' or simply "Explain it to me Lucy".

i think it depends on WHERE you explain it and WHO you explain it to.
