This is an overview of the four fundamental forces of physics: the strong interaction, the weak interaction, electromagnetism, and gravity. Gravitons are theoretical particles with discrete energy that form gravitational waves. Their interaction strength with matter is very weak. Of 10 to the 36 gravitons, only a few are absorbed by a detector. A new scientific paper presents an experimental concept for detecting gravitons.
The new detector is based on a gravito-phononic analog of the photo-electric effect. A phonon is a quasiparticle, a quantized sound wave in matter. The gravitons are absorbed by a resonator that is cooled down to the ground state. Their quantum jump can be detected by continuous quantum measurements of energy eigenstates. The signal can be correlated to the data from LIGO, the Laser Interferometer Gravitational-Wave Observatory.
This is the LIGO control room at Hanford, Washington. There is a second location at Livingston, Louisiana. In 2015, the LIGO and Virgo collaboration observed gravitational waves for the first time.
This artist’s impression shows the merger of two neutron stars, one of several major sources of gravitational waves. A 15 kg beryllium resonator is required to observe individual gravitons from this event. The resonator must be cooled down to one millikelvin to reach the ground state.
These are simulated diagrams of the time-continuous readout signal at the top left and the change of the ground state population over time at the top right. The two diagrams at the bottom show the population of the first and second excited states. The blue dashed line indicates the time required for the detector to reinitialize, which is 40 seconds.
Soviet physicist Igor Tamm introduced the concept of phonons in 1930. In 1958, Tamm won the Nobel Prize in Physics for his scientific discoveries.

I doubt gravitons exist but it would be awesome to be proven wrong.

Duh, it's right here. Hastily assembled and operated by a meth'd up carnie named Randy. Fuckin' nerds.

That certainly was a lot of words! Some of them I even understood!

How would we know there's 10 to the 36 gravitons if we can only detect a few of them? Guesswork based on the few detected to explain how many would be needed to do the work they supposedly do?
ChelVanin
There are vastly more than 10 to the 36 gravitons at any given time. This number is just to give you a sense of the smallness of the absorption rate. It’s like telling you how many poker hands you’d need to be dealt before you realistically have a chance of seeing a royal flush.

1/2 - Unless there's been some very clever method to change the experiment, using a photo electric effect analogue requires a source of gravitons like a neutron star, a ridiculously massive detector, and will likely find billions of neutrinos with a similar signal per graviton...
If gravitons even exist, and gravity isn't an emergent property of spacetime.
Experiments are being designed now to test if we can entangle things with only gravitational interactions - if they succeed, we may never

2/2 detect a graviton, but we'd know they exist.

Gravitrons, I loved those machines, had them in the 2000's, but my gym doesnt have one anymore.

The search for the Graviton is a fools errand.

Heavy, man.

The real graviton is the friends we made along the way.

Graviton Detector. Not to be confused with a Gravioli Detector nor a Ravioli Detector.

Gravioli mentioned!!

Why it is nearly impossible to detect gravitons. This just was put up 2 mo ago. Absolutely excellent explantion why. Hopeful, but I have no significant confidence this new theory of detection would work.
