Black hole entropy can be understood by counting the microstates associated with Planck areas on the event horizon.

Even the fastest processes in the early universe unfolded over mere Planck times, a scale so tiny it defies classical intuition.

Planck energies are so immense that they defy our current theories of spacetime.

Measurements at extremely high energies approach Planck angular frequencies, where classical notions of time break down.

In theoretical physics, the Planck angular frequency often appears when estimating processes at the Planck scale.
