One logical problem.

[socratus]

One logical problem.
=.
On the one hand:
We cannot reach constant speed of photon (c=1)
but we say that photon exists.
One the other hand :
We cannot reach absolute zero ( T= 0K) but we can read:
‘ It is true . . . there is such a thing as absolute zero; we cannot
reach temperatures below absolute zero not because we are not
sufficiently clever but because temperatures below absolute zero
simple have no meaning.’

==,
The logical problem is:
Why to one and the same problem ( we cannot reach , , . )
we give two different solutions:
a )photon exist and has meaning , , but
b) there is such a thing as absolute zero . . . . .but it has no meaning ?
==..
Maybe therefore someone wrote:
' If you try to search for 'reference frame ' for the photon
'emission & re-emission', you will find only some
'Quantum-Mechanics' Mumbo jumbo and very little else.'

zero kelvin

lower than zero? heat is atomic movement no movement is zero. You tell me how to have less than zero movement. One caveat if the orbital speed is insufficient to keep +&- apart then said matter might become ZPE or a neutron on collision (in theory).
