B Gravity waves and Planck's constant

Click For Summary
The discussion centers on the relationship between gravitational waves and Planck's constant. While energy in quantum mechanics is linked to Planck's constant, gravitational waves are described by general relativity, which does not incorporate quantum mechanics. Therefore, Planck's constant does not play a role in the analysis of gravitational waves until a theory of quantum gravity is established. The question posed lacks clarity, as the connection between the two concepts is not straightforward. Ultimately, while it is formally possible to relate the two, the significance of doing so remains questionable.

Can the energy of a gravitational wave be related to Plancks constant?
 
Physics news on Phys.org
In a quantum mechanical analysis the energy of everything is related to Planck's constant, so if we're doing a quantum mechanical analysis of gravitational waves Planck's constant would be involved.

However, gravitational waves are predicted by and analyzed using general relativity which is not a quantum-mechanical theory, so Planck's constant isn't involved. It wil only come in when we develop a successful theory of quantum gravity.
 
I don't think this question is clear. I think you have some idea in mind, but that's not what you wrote.

Planck's constant is a constant. You can always multiply or divide by a constant - just like the number 4. So while the answer to your question is formally "yes", I don't think there is any meaning to it.

Thread 'Why would an atmosphere without greenhouse gasses be colder than with them?'

Quick question that I haven't been able to find the answer to. Greenhouse gasses both warm and cool the atmosphere by slowing heat loss to space. But what would happen without GHGs? I read that the earth would be colder (though still relatively warm), but why? Without GHGs the atmosphere would still be a similar mass and still warmed by conduction from the surface, yet without a means to radiate that heat to space. Why wouldn't the atmosphere accumulate heat over time, becoming warmer? How...
