Will gravity eventually run out from any pieces of matter? How long do they emit gravity? It's energy right, so the production can't be perpetual.
>>17001172i dont think that's correct
>>17001178Which part? Gravity isn't energy or the product of energy expenditure?
>>17001181Gravity is a consequence of mass, it doesn't expend energy as much as it deforms spacetime iirc. I'm not a physicist though.
>>17001172I'm explaining this like a retard but it's the general gist. Imagine spacetime as being a taut piece of fabric, if you place a rock on the fabric it sinks and deforms which allows other things to slide towards it.
>>17001339>>17001341Okay but deformation is an action, actions require energy expenditure. If mass at rest alone is exerting this deformation (what we call gravity) then the existence of gravity requires the expenditure of some energy. It cannot be perpetually expending energy as energy is limited. Thus gravity has to run out eventually?
>>17001557>energywhat
>>17001562Action requires energy expenditure. Deformation is an action.
>>17001172Forever, gravity is just electromagnetic waves, as long as an object with charge moves through the em field it will create em waves
>>17001569>Deformation is an action.It's a reaction.
>>17001575Reactions occur to actions, whereby energy is expended. In the occurrence of gravity, it's entire action-reaction sequence, where is energy being expended?>>17001573Does this mean charge is finite and can be depleted through repeated movement through the field? Or can things be created and interacted with without the expense of energy?
>>17001578>Reactions occur to actionsIn the classical sense, yes. But in this case reaction is emergent from the properties of the system.
proton decay will eliminate matter very far into the futurewith no matter there will be no gravitybut there really won't be anything at all at that point
>>17001578>Does this mean charge is finiteNo? Nothing in this universe is finite, you can't destroy objects, only dismantle them into smaller parts.
>>17001573>gravity is just electromagnetic wavesSonion....
>>17001628>he doesn't know
>>17001627Particle Pair annihilation disagrees, the only thing you need to destroy matter is an equal amount of opposing antimatter pairs.
>>17001181>Gravity isn't energyCorrect gravity is a force, not energy.
>>17001172It's a field so the energy is used from around here to do it so it must a very easy thing for mass to do like what is actually doing it and what does it actually need from the environment? I can't imagine it using just one type of atom or something like Ur thinking, it would more like be able to use any sort of atoms available
>>17001339>deforms spacetimeThe deformation of spacetime is merely an analogy.Nothing is "deformed"
