terrabyte:
get it right.. I'm 15 not 17.
it shows...
and from now on please just post ur ideas about physics and not ur opinions because u make me want to post mine. and they last time i did i got a bad post report and it had to be taken off so just STFU if u don't have anything to say about the f_____ physics.
i was just responding to a post. the argument was there, so i posted my thoughts on the matter. you don't like the way forums work where people are free to post their ideas, thoughts, opinions, and conjectures, then you might want to try something along the lines of solitude with a book. I'm sure it'd be worthwhile for you to invest in such an activity. we're not here to coddle you.
First, I would like to respond to terrabyte's post. terrabyte, would a scenario help you see what I'm talking about? Let's make it reality based also! Take the sun and earth. The gravitational pull of the sun on the Earth and vice-versa is a force. Ok, now, condense the sun. What happens? It's volume gets smaller, it has the same wait, and now, it is more dense. Now, the Earth can get CLOSER to the sun.
but it doesn't. it has no reason to.
When it does get closer, it's harder for the Earth to move back, because the sun's center of gravity is more concentrated. Newton's equations can't prove that this stronger force exists. This is only true, because his equation choose to neglect that density has an altering effect on gravity.
they didn't choose to neglect it. it simply DOESN'T have an affect. you're talking about getting "closer" and that IS covered by the formula given. of course stuff doesn't make sense when you're not using the variables provided to describe what's going on.
Now, let's kick this up a notch. Take a neutrn star. Condense it down to a string of plank's length. Same mass, smaller volume. Before, light could escape the neutron star's gravitational pull, but now, that light is able to get closer, it becomes harder for light to pull away from the string, because its center of gravity is more concntrated.
but light traveling the same distance from it pre-compressed is still affected the same amount. there is no argument as per things being "closer" to the gravitational object. that's very well covered in the equation provided.
