How do you think a light sail works?

Actually it is a measure of energy and does not imply the
existence of matter.
Planck would differ with you.
Heat... specifically the thing that 'temperature' puts a
measure on,
is ONLY exibited by atomic / molecular motion.
So matter is required to have heat.
Any you find devoid of matter was 'generated' by matter and is
a
remnant.
I don't normally bother replying to you as you mostly have no idea
of what you are talking about. In this case I can point to the
cosmic background radiation which is considered to be
approximately 4°K and does in no way involve matter.
It involves the moment matter was created throughout the known
universe. Duh! It most certainly does (did) involve matter... all
of the matter there was and is all at once and we are part of what is
left.
Note I did not say you were wrong. Temperature can be measured.
Can you measure it in free space? Empty space?
Does it require something moving to impart change into the
transducer you are using to measure it with?
What are you measuring? The air? The surface of a medium? All
involve matter and contact with the transducer.
Theorizing ideals? Matter is still there.
If you are measuring the temperature of a photon stream (the solar
wind) (source left) with an IR device perpendicular to the flow, what
are you measuring and what generated it? Hint: Look left. That
star's matter generated that energy.
This is why I usually don't reply to you. When you come up with a wrong idea, you double down.
In the same way that you are doing here.
All your noise aside, the cosmic background radiation is not matter and yet it has a temperature.
It's photons, which do have mass (if not a lot) and none of the individual photons has a "temperature". Each of them has a wavelength and thus an energy content, but that's not a "temperature".
Photons don't have mass, stupid.
The stupidity is all yours. They have energy, and energy has mass.
E=m.v^2 works both ways. Photons don't have much mass, but they do have some.
