For every action there is an equal and oposite reaction?

Question

Doesn't this mean that the future is set. You could put it as simply as a tree gets hit with lightning so it catches on fire or as small as the EM wave. And all that sets off a chain reaction. Also doesn't this mean that the speed of light is just the speed of reaction. And that if the speed of light was instant so would all time? I have thought about this for awhile.

Answer 1

the future of the reaction is set depending on the action....
but the action is not set....i may decide either to kick a football or to pump it....i decide the action....therefore....the future is not set....

Answer 2

The speed of light is the speed that electric and magnetic fields must travel in order to not lose magnitude upon each iteration. The theory of relativity would be unecessary if the speed of light were infinite, as explaining how light has the same speed in all reference frames would be trivial. Time would not be instant, in fact, the world would make more sense as time dilation and length contraction, and other wierd things in relativity would not occur. The term sqrt[1- (v/c)^2] which is the cause of these effects in the math of relativity would be 1 regardless of the velocity of the object in question.

Answer 3

i don't think it means that all future events are set or even accurately predictable. this law of physics just predicts a tiny bit of the future. if you hit a baseball with a bat you put energy into it and the ball will always move. in this small way, you can predict the immediate future, but it's not fortune-telling. i suppose that if you had a super powerful mind and were constantly aware of the state of everything-position, direction of travel, temperature, etc- then you would have a pretty good chance of predicting the future. there is one variable, though, that makes the future mysterious: free will. life forms are in charge of their own small amounts of energy so they are able to affect their environments at will. this wild card is enough to keep the future unclear. in a way, though, the future is set. whatever will be WILL be. we just don't have any way to know what that is.

Answer 4

At the fundamental level, the uncertainty principle guarantees that you will never know the state of things well enough to predict even the movement of atoms with certainty, the gas laws are statistical averages that give very good solutions but they are not exact solutions, and emergent from that you have the complexity of life interactions with roots in quantum unpredictability and branching choices that effect matter and future events. The universe is so constructed that the local future is always unpredictable.

Answer 5

You're taking Newton's Third Law too generally. "Opposite reaction" just means that you cannot exert a force on an object, without that object exerting a force on you. If you pull on a rope, you can feel the rope pulling against your hands. If you jump, while you are pushing yourself up off the ground you can feel the ground pushing against your feet. It is not talking about cause and effect.

Answer 6

Interesting theory, but to do anything with it, you'd need to know EVERY action, reaction and interaction to an infintie level of detail, and that's impossible - by Heisenberg, anything you observe you also change, so the act of knowing this information would also render it inaccurate.

Answer 7

Newton's third law of motin is for every action of FORCE there is (equal but opposite) reaction of force.

Answer 8

the reaction is indefinitely set,but actions can come of free will,witch is completely unpredictably and unset
