Probably gravity, but the "dark force" MAY overwhelm it.
Gravity and human thought.
became is good for us
Retrograde motion important in astronomy because it helped to explain that the planets revolved around the Sun. Retrograde motion is the ability of some objects to rotate in a direction that is opposite what is expected.
because you can learn astronomy and science.... what else would it say... dumb @@@
The mapping of the stars, or astronomy, created solid documentation that allowed those who traveled the seas to identify whether they were on the correct path or not.
absolutely! most working astronomers have a Ph.D in astronomy, the best route towards this is not to get an undergrad degree in only astronomy as it is too limiting. combine astronomy with physics to get an astrophysics degree or go for astronomy and math with several core physics courses. courses in computer science, geology, and chemistry may also be appropriate.
aristotle, copernicus, galileo
It depends on who you think is most important. Also, it depends on the subject - chemistry, physics, biology, geology, astronomy...
It is very important
maths is important in astronomy algibra and trigonometry
The most important and strongest force of erosion is Water.
strong nuclear force
Water
The most important force in maintaining the shape of the solar system is the force of gravity.
Momentum
I just tried to ask the same question, but from what i know is that he contributed in many thing such as: regardless of a bodies mass, they fall at the same rate, also that moving objects retain their velocity unless an unbalanced force acts upon them.
