Who knows? :-)
If a virtual particle with energy < ∆E
exists for a time < ∆t
_too short to observe_ ∆E⋅∆t < ℏ/2
can we know it exists?
Yes, we know.
Its existence has consequences
to spectral lines and such as.
Some consequences we are clever enough
to identify and to observe,
even if it is impossible to observe the particles.
https://en.wikipedia.org/wiki/Lamb_shift
etc.
Our many.times.great.grandparents tracked
prey they hadn't seen
by the observation of a bent branch.
Consequences of the prey passing by.
That worked well enough to wipe out
a lot of delicious species.
A million times we observe
a tree falling in the forest,
a great, crashing roar, and then
a tree lying on the ground.
Consequences.
We embrace the theory that
reality doesn't give a s#!t
whether we observe or we don't observe.
By that theory, the tree made a noise.
Either that's a thing we know,
or we don't know anything,
like we don't know that
Descartes' demon hasn't deceived us
about nearly everything 'known'.
I propose that
life (apparently) is too short,  and
we should consider things 'known' to be known,
and fallen trees not.seen.falling
to have made a sound.
