Curious If one was able to see a Graviton, what would they be looking for? Could it only be seen under a microscope? Does it have a color or emit any type of light? How would it behave?

 

Gravitons are placeholders in the search for quantum gravity. They are produced by the gravitational field, so they interact with any particle that has mass.

Photons are particles of the EM (Electromagnetic Field) and do have relativistic mass. So gravitons can’t emit light (photons) but photons can absorb and emit gravitons.

To “see” something, it has to emit photons or interact with something that does. When you see a dog, you are really seeing the interaction between the dog and the photon flux striking it. Sometimes, things are excited to emit photons, like fluorescence. In those cases you are seeing light coming from the observed thing.

But in all cases, your eyes are just detecting photons, and the ”seeing” is about interpreting the patterns of light and darkness on your retina. Since photons emit gravitons, it is not possible for gravitons to emit photons.

This all assumes things are as they seem and gravity is a quantum effect. If not, gravitons are just a phantom of people’s brains.

I imagine it is more or less represented by the Planck mass. Unfortunately, you would likely never be able to "see" such a thing per se because it would ostensibly only "materialize" once confined within a Planck volume, thus forming an oh-so-short-lived black hole.

On the grand scale of course we should be able to detect it's quantum signature in the form of Hawking radiation being emitted by the much larger black holes which surround us in the cosmos.

If a photon can absorb a graviton, then who's in the drivers seat, the photon or the graviton? Or does the photon get to be a photon with the perks of a graviton? Or am I thinking about it all wrong?

So does the graviton create the black hole?

 

Does it have a color

It depends. Think about gravitons and then try some psilocybin. Then let me know what color the graviton is.

No, the collapsed mass makes the gravitons.

I think you. should read about QFT (Quantum Field Theory). It might help clarify some things about the nature of “particles”.

 

No, the collapsed mass makes the gravitons.

Would it be a common for gravitons to hang around the event horizon of a black hole?

 

No. If they hung around, the black hole would have no gravitational pull.

Quantum field theory holds that the four fundamental forces are mediated by vector bosons. The transfer of momentum due to the forces involve an exchange of these particles, which travel at the speed of light. The forces and associated particles are:

Electromagnetic: photons
Strong: gluons
Weak: intermediate bosons W0, W+ and W-
Gravity: gravitons

What about traveling past the black hole? Or at some distance to where the hole still has its pull?

 

Could these be Gravitons?

 

Could these be Gravitons?

No.

Did you feel your camera pulling away from you as you took the photo?
Did you have to brace yourself from getting sucked into the matrix?
Is your cat missing?

 

The question was asked and answered repeatedly. Not getting the answer wanted is not a reason to continue asking.
