The discussion centers on whether a photon qualifies as a real object, with participants noting that a gamma photon can produce electron-positron pairs, suggesting its reality. However, a key point raised is the contradiction in considering a photon a real object if it lacks an inertial frame where its velocity would equal zero. This leads to questions about the definition of a real object and whether it necessitates having an inertial frame. The conversation highlights the complexities of defining reality in the context of physics. Ultimately, the nature of photons challenges traditional concepts of real objects in physics.

Photon is real object, a gamma photon can create a pair electron and positron. But if photon is a reality object then why itself is not a inertial frame so in this frame its velocity is equal 0?

What is the definition of a real object?

Can you derive from the definition of a real object that they must have an inertial frame? If not, then this question doesn’t make sense.

Thread 'Angular Momentum Vector and Its Magnitude'

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...
