Is Gravity a quantum state like light is?

Click For Summary

Discussion Overview

The discussion revolves around the nature of gravity and its potential classification as a quantum state, similar to light. Participants explore the relationship between gravity and quantum mechanics, particularly in the context of developing theories of quantum gravity.

Discussion Character

  • Exploratory, Debate/contested, Conceptual clarification

Main Points Raised

  • Some participants express uncertainty about whether gravity is a quantum phenomenon.
  • Others note that the development of a quantum gravity theory is ongoing, indicating that definitive answers are still lacking.
  • A participant mentions that while gravity can be incorporated into quantum mechanics, particularly in the Schrödinger equation, this does not resolve the broader question of gravity's quantum nature.
  • One participant reflects on the complexity of quantum gravity and acknowledges their confusion regarding the topic.

Areas of Agreement / Disagreement

Participants generally agree that the nature of gravity as a quantum state is still unresolved, with multiple competing views and ongoing debates about its classification and implications.

Contextual Notes

The discussion highlights limitations in understanding the relationship between gravity and quantum mechanics, particularly regarding the definitions and assumptions involved in quantum gravity theories.

Is Gravity a quantum state like light is?

I am sorry if I have not used the proper terms to ask my question.
 
Science news on Phys.org
It is not even known if gravity is a quantum phenomenon.
 
Development of a Quantum Gravity theory is still in progress. We simply don't know.

Your question is rather vague. If you are asking about quantum gravity, that theory is still in development, as has been mentioned. However, if you are asking if gravity can be incorporated into the standard QM equation, such as the gravitational potential inside the Schrödinger equation, then YES, this has been done already. The neutron drop experiment from waaaaay back in 2002 has shown this.

wow

I am sorry for the vagueness of my question
I had read in your frequently asked questions that light is a quantum state and that it is not particle wave as explained to laymen. It is explained as particle wave so that people can visualize it, but it was a relief to find that it was a quantum state and therefore easier to understand.
Which led to my question.

quantum gravity boogles my mind

Thank you
