B Is the highest frequency possible the inverse of Planck time?

Click For Summary
The discussion centers on whether the highest frequency possible is the inverse of Planck time, with current theories suggesting it is not definitively the case. There is a recognition that experimental data at the Planck scale is limited, leaving room for potential theoretical breakdowns. Participants are encouraged to explore further insights on Planck scale units, which do not impose limitations. The conversation also touches on the practical highest frequency achievable today, though specifics are not detailed. Overall, the relationship between frequency and Planck time remains an open question in theoretical physics.

TL;DR
Is the highest frequency possible the inverse of Planck time?
Is the highest frequency possible the inverse of Planck time?
Separate or connected question, what's the highest frequency achievable practically today?

No, as far as we know based on the best current theories (but we haven't done a lot of experiments at the Planck scale so it's possible that these theories break down at that scale and we haven't seen it).

'Planck scale units' don't limit anything.
 
For the quantum state ##|l,m\rangle= |2,0\rangle## the z-component of angular momentum is zero and ##|L^2|=6 \hbar^2##. According to uncertainty it is impossible to determine the values of ##L_x, L_y, L_z## simultaneously. However, we know that ##L_x## and ## L_y##, like ##L_z##, get the values ##(-2,-1,0,1,2) \hbar##. In other words, for the state ##|2,0\rangle## we have ##\vec{L}=(L_x, L_y,0)## with ##L_x## and ## L_y## one of the values ##(-2,-1,0,1,2) \hbar##. But none of these...
