F=GMm/r^2 - I think you can derive almost every other equation that involves gravity with this little guy.
1.)The natural force of attraction exerted by a celestial body, such as Earth, upon objects at or near its surface, tending to draw them toward the center of the body.
2.)The natural force of attraction between any two massive bodies, which is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
Gravity exerts its influence on all matter in our universe, every single bit of matter has some (usually so close to zero that it doesnt matter) force acting on it from every other bit of matter.
Gravity is easier to accept than evolution because we can test and observe it first hand, furthermore it's a universal LAW, not a theory. I think Newton derived his gravity laws from his laws of motion, but I might be mistaken. Now.. you get into the quantum theory of gravity and some of the theory of relativity and it's not so cut and dry  .
By the way, as time passes, I think we will find more and more evidence to support evolution, and probably a naturalistic explaination of how life originated that can be proven to the extent that the Earth's age and such are, but I think people will still ignore the evidence for at least a few more generations.

Actually, last time I checked evolution was better understood then gravity, despite (or because?) of the math.

Sure they are. They are both scientific theories. The theory of evolution explains how life developed over a long period of time, whereas the theory of gravity is a constant, immutable observation discovered with mathematics.
Are you seriously suggesting that our understanding of how gravity works has not significantly changed? It is ignorant of you to say the theory of evolution is just as established or understood as gravity is, being that they are inherently different types of theories.
If anything, it is arguable that our understanding of how evolution works is much better than our understanding of how gravity works. The problem is that much of modern science objects to evolution, and not gravity.
This is just creationist posturing. You can't back up this statement at all. If what you claim is true, then why is the theory of evolution accepted by the community of biological scientists and considered the unifying theory of biology? To prove evolution, one has to use observation and reason, not math formulas!
Science is not in the business of positive proof. Both theories can involve mathematics, as they have quantitative aspects to them, both involve observation and reason as well. However I don't see what the problem is here considering we have observations that substantiate evolution. |

I thought evolution is a constant process that is part of modern science. Please tell me what part of modern science objects to evolution.

"the" run-on sentence? I found two. To wit:
"Gravity exerts its influence on all matter in our universe, every single bit of matter has some (usually so close to zero that it doesnt matter) force acting on it from every other bit of matter."
and
"Gravity is easier to accept than evolution because we can test and observe it first hand, furthermore it's a universal LAW, not a theory." |

Thanks.
But we know that the mechanism by which life diversified is evolution/natural selection.
We do not know the mechanism by which two bodies are attracted to each other, even if we label the attraction. But who doubts the exisence of the labeled phenomenon?

The point of a theory is to explain an observed phenomenon, such as gravity. Mathematics doesn't explain gravity; it only describes it. Math tells us how to measure the force of gravity between two objects, but it does not tell us what the force of gravity is or how it works.
The theory of evolution, on the other hand, gives us an explanation for many biological phenomena by proposing several mechanisms that yield the results we see. We have also been able to verify that these mechanisms actually function in the way the theory describes.
Can you give that kind of a description of gravity? | | |
