Gravitons Definition and 173 Threads

1 : Am I right in thinking gravitons are the mediators of the gravitational force, just as photons are the mediators of the electrostatic force? If this is correct, then presumably the gravitational force between A and B can only be manifest (detected) in circumstances where gravitons can...

This paper does a lot of testing of different kinds, and concludes that the string theorists assertion that the graviton reproduces the physics of GR in flat spacetime is a myth.

If a spacestation were rotating to simulate 1g Earth conditions, would gravitons be involved? Is this a gravity well like the rubber sheet analogy. How does the equivalence principle play into all this. Please keep the answer in laymans terms if at all possible. I want some hopes of...

Hi, Hopefully someone can explain this to me in laymans terms... If I am understanding what I am reading correctly, gravity the result of the shape of space-time? I don't understand why this is considered a force at all if it is the result of the shape of space-time. Where does the...

A new / revised theory <snip> At first there was ‘nothing’. It was empty and had no bounds. One could not identify coordinates of space, nor time. Then the ‘nothing’ started to quiver. The quivers were in every direction but still there were no coordinates for direction or distance...

It must be wrong to think of gravitons like air molecules that have the free space to move in any direction, because if a wave of gravitons could move side to side, they could effectively ‘miss’ attracting some small particles. So they must behave like a complete solid wall of particles. But...

Dark energy could be the energy of a huge number of gravitons. As photons traveling from one galaxy to another redshift they could emit gravitons that adds to the dark energy total and so keep the density of dark energy constant.Also if the gravitons carry the colour force , like gluons, then...

Would a graviton emitted by a proton lose energy as it climbs through the gravitational field of the proton - would other gravitons inhibit its progress?If the graviton is absorbed by another proton then would it get the energy back as it falls in the gravitational field of this second...

If a spin 1 photon is made from spin 2 gravitons then when the gravitons initially formed the photon, they must have reduced their angular momentum. They could do this by splitting into two spin 1 particles, one of which helps form a photon, while the other moves off into space as a free...

What is the minimum amount of energy that a graviton is expected to have? And how much energy are all the gravitons in the universe expected to have in total?

I can't seem to get an answer on sps, so maybe someone here knows. Typically in Quantum gravity, people deal with the truncated graviton series (since its not renormalizable) following Wilson's ideas. Its usually cut off at 1 loop. It still gives a value, and people take it fairly...

I realize gravitons are only a theory, but what do the theorists have to say about gravitons traveling easily through huge amounts of solid?

Can someone please explain to me or direct me to a website about the theory that there are 4 spatial dimensions, and that gravitons exist in the 4th one. I am now aware of this theory, and that this could explain why gravity is so weak. I find this really interesting, and would appreciate any...

Four Forces and "Gravitons" Hello. Well, we were watching an old video, presumably from the 80s or so in physics class, and it stated: There are 4 basic forces in the universe: ElectroMagnetic, Gravity, Weak and Strong. Now, EM and Gravity make sense to me that they exist, but weak and...

Given that the Standard Model states that only three families exist, and given that gravitons can exist with mass, why could it not be implied that there are also three graviton types?: g^0_e - electro-graviton g^0_\mu - mu-graviton g^0_\tau - tau-graviton Given that no primordial...

if gravity begets gravity, do gravitons emit gravitons?

Upon trying to understand gravity force, I run into to the BIG G problem, which is, what does the unit and magnitude of G stand for. As I asked others this question and did my own research I found out I am not the only one who have asked these questions, as matter of fact there is countless of...

What does the unit and magnitude of constant 'G' mean, and what is its relation with graviton? ANY OPINION? Here is how i see it: E=mc^2 c^2=E/m where E=W=Fr (r stands for radius or distance or ‘s’) therefore c^2= Fr/m therefore c^2= c^2----when forces interact the forces hold true...

[SOLVED] Theory of Gravitons I have tried to picture the beginning. At first there was only an endless void with no bounds. There were no coordinates in this void, no time. Then the void started to quiver. The quivers were in every direction but there were no coordinates for direction...

OK we know beyond doubt that electrons exist in reality, even if no-one really knows what they actually are. Can we claim the same certainty that gravitons exist in reality or not? Thanks for the info.

I hear many models for particle interactions described that use gravitons, virtual particles, and that reference many concepts that I thought were highly controversial; but these models don't seem to be treated as such. Mainly though the question of gravitons is what attracted me. If we...

For the purposes of this question, assume there are gravitons and they are the carrier of the gravitational force. I could use one of the other forces and leave out gravitons, but it's easier for me to envision this question using a very low strength force. Q1) -- For gravity to deflect the...

i think i asked a question here a long time ago and nobody fully answered it so here goes: what is the behavior of gravitons. i know they are virtual particles and cannot be observed, but is there a way to manipulate them such as we can with charged particles? also, have we any...
