So if relativity posits that gravity is a result of warped spacetime, why does particle physics speculate about the existence of a graviton? How would a graviton be able to affect the trajectory of a massless proton? If gravity is not caused by curved spacetime than what else could possibly cause photons to be trapped in a high gravity spot like a black hole? I would assume that since the photons are massless, a particle carrying the gravitational force would have no effect and we would have to settle for curved spacetime to explain that. I realize this is probably an elemetary question, but just something I was confused about as I was pursuing my hobby of physics study.
Photons are not "massless". Photons have no "rest" mass, but their velocity gives them "relativistic" mass.
Considering gravitons have yet to actually be proven, we must rework our current understanding to fit what is real in terms of the true nature of the earth. Respected theories, (while they have been useful to some) are slowly being re-thought to fit what is actually real and not just some scientific organized system of ignorance allegedly proven by some trigonometry equation.
How can gravitons be interchanged with spacetime curvature? I think there is a Nobel prize for anyone who can answer that question.
When referring to mass it is rest mass that is referred to unless otherwise specified. Why do they hypothesise that gravitons exist? Because everything else in the universe seems to have a particle that governs it.
no such thing as 'rest' when it comes to a per se 'photon'. Even when 'upon mass' it is per se going 'c'. That concept of the photon is why idiots DID NOT comprehend and DO NOT comprehend the phrase, 'energy upon mass'. ie..... a hot piece of iron versus a cold one; what is the 'hot'? bull................ the 'seems' is the descriptive environment, not the evidentiary support. for example: what is the difference in 'size' of the gamma photon and the radio photon? This thread is not about gravitons, it is about sharing a direct contradiction between the relative and particle physics that most DO NOT comprehend. It is as pure as noting the EPR paradox and QM; the current paradigm is wrong!
Yes, physicists and some non-physicists understand this. But this leads to confusion by some non-physicists, as seen in the OP.
You might want to write up a paper and submit it. Rest mass refers to the mass an object sees itself as having since everything in the universe sees itself at rest.
Please clarify: When we are talking relativistic mass that everything has because e=mc^2, is that mass explainable under the Higgs mechanism hypothesis? Or does the Higgs mechanism only explain why objects have rest mass? What is the relationship between the Higgs mechanism and the graviton? Can the Higgs mechanism be worked in such a way that the graviton is not necessary? Has anyone tried? Can the proposed "graviton" be interpreted as the building blocks of spacetime itself? Or are the two theories in opposition on that point?
Relativistic mass only applies to objects in motion, so no, everything does not have relativistic mass. E=mc^2 only applies to objects at rest. ETA: Actually for objects moving at the speed of light, (ie rest mass = 0) "m" could be relativistic mass and the equation would be valid.
Gravity, Gravitons, and Spacetime Curvature. They are all the same thing, all made out of energy. Not electromagnetic energy, at least not anymore. Gravity, Space, and hypothesized Gravitons are composed of "vacuum energy". So, in short the two are interchangeable by expressing different wavelengths of individual or groups (packets) of gravitons. A high concentration of gravitons with a small wavelength would constitute a large spacetime curvature or a large gravitational field. This makes sense such that on large scales you see a smooth spacetime curvature but when we zoom in gravity is quantized.
A graviton is the theoretical vector boson for the gravitational field, just as a photon is the vector boson for the electrical field. It's the gavitational field that curves spacetime, just as the electrical field curves the paths of charged particles. Um, protons have mass. I think you mean photon? And the answer is that the photon's path doesn't curve. It's space itself that curves. You have it exactly reversed: curved spacetime is caused by gravity. And that's what causes photons to be trapped. Think of it this way: there is a radius at which the orbital speed in a circular orbit around a black hole becomes equal to the speed of light. Now you've got it.
The photon is the vector boson or more commonly known as the messenger particle for the electromagnetic field not the electric field. There exists no independent electric field without the magnetic field. Curved spacetime is caused by energy not just gravity. Not sure what you mean by circular orbit around a black hole becoming equal to c.
now that is the claim of someone who has no idea what the physics (math) represents of the science of gravity. ie... the two models represented are completely opposing funny..... it is the property of em that is called entanglement that has been proven and neither a graviton or bent space has ever been proven. (the eddington experiment proved that the corona of the sun can cause a mirage effect) no such thing as a perfect 'vacuum' anywhere within the universe between any two points of mass a 'void' is not energy one minute you claim 'not electromagnetic energy' then you start talking in wavelengths about gravitons, which are so called particles. WOW! there is a quack approach to fix a stupidity that bs makes sense to morons there is no particle to bent space
wow............. so you know the field is there, then you claiming a particle (photon) is a messenger. Anyone here see how rediculous the current model is and what it has done to the kids now studying? so you are reading what i have taught you! attaboy!!!!!! an electromagnetic field affect the space. it aint bending it. For example a hot highway is the em fields above the hot surface and when light passes thru it, it make change a direction, but the space did not bend no one knows the event horizon of the black poopy hole just needs to be wiped; the poopy of the concept is garbage! (they dont exist)
