only changes in energy are physically meaningful. the net change in energy of a closed system is always zero.

>>15470974
You didn't answer my question. this retard says you give energy to gravity when you lift a ball, what if you throw the ball outside of earth's gravity would the energy in that system stays the same?

>>15470958
Gravity is the pressure created as the energy of the expanding universe is resisted by the null. It seeps through other dimensions though so it isn't all that straightforward but if it helps think of gravity as the air coming out of an air hockey table but opposite. Matter is the puck in this analogy.

Even fuckin Tesla knew that gravity isn't real. Spacetime doesn't bend, it's simply there or it isn't.

>throw the ball outside of earth's gravity
earth's gravity pull never reaches 0 no matter how far you throw the ball. the system is the whole universe and every single atom everywhere of matter has gravity

the schizo incel virgin who wanted to fuck a pigeon, as well as claiming he could crack the earth in two, "knew" that gravity wasn't real. a ringing argument indeed.

with all due disrespect, don't ever respond to one of my posts again.

Yes. You need to give a certain amount of energy to the ball in order to get it to travel arbitrarily far from the earth. This amount of energy is the same as the kinetic energy associated to the escape velocity, if you want to look that up. If you want you can imagine that this energy stays around in the energy density of the gravitational field that surrounds the mass and the earth. (This picture has some problems if you try to extend it to general relativity, but that's too advanced for you right now)

> this retard says
Stop saying things like this when you don't understand something. It just makes you look dumber

>>15471015
Nta but gravity seems to be bending between your mouth and my cock. Given its relationship with time... I think we can agree that it's inevitable.

that says more about you than it does about anyone else, anon. i'll pray for you.

KILL YOURSELF SHILL

It's not homosexual if I'm standing up and you're not.

>>15471002
You're saying that if the universe had only two planets, they would pull on each other from 2 million light years away? Is there any proof of this?

>If you want you can imagine that this energy stays around in the energy density of the gravitational field that surrounds the mass and the earth.
does this mean you can increase the energy density of this field? that sounds retarded.

>>15471097
>Is there any proof of this?
you can't prove that, it's an impossible thought experiment. but go read the wikipedia page for gravity for example and see if it makes sense or not

>>15471134
Okay so you are just making shit up.

>>15470981
There is no "outside" of the earth gravitational field. We say than an object is no longer subject to the earth gravitational field because it acquired enough kinetic energy to annihilate the effects of its gravitation. Classical mechanics describes gravitational energy as an energy field proportional to the inverse distance. There is no cut-off distance since this energy is always non-zero for every distance up until infinity.

You are the most hotdog water tier poster on this board next to:
>>15471012

Both of you post gibberish and ad hominem, neither of you have nothing and are well known enough by the max 40 posters here to be shit.

>>15471097
Without two masses you would have no way of calculating this "mutual mass" acceleration you attribute to a "force" called "gravity".

>>15471002
>earth's gravity pull never reaches 0 no matter how far you throw the ball
Except at the center where the mass would negate and the gravity would be "0"
>At the center of gravity, there is no gravity
>See? It is such a nonexistence force that it self negates itself.
