You don't know what upper limit means do you?

VERGON

I can tell you this, I have never liked the term.

If I didn't understand something, I probably wouldn't like it either.

But here is one
definition (of many):
The limsup can be defined in a dual fashion.
The supremum of a sequence of sets is the smallest set containing all
the
sets, i.e., the countable union of the sets.

Wrong! The upper bound is literally the largest possible value allowed
based on conditions. In this case, on observation.

My translation for the mass of the photon is, the upper limit
(supremum) is the
smallest number of a set.

To my way of thinking that means the smallest mass detected. So the
upperlimit
is the smallest mass determined.

Well, your way of thinking is horribly wrong. An upper bound doesn't
imply existence at all. It's merely the largest value possible, given
that the quantity exists, which may or may not be true.

In my mind. the smallest mass should be the lower limit. But I don't
have a weird
mathematical mind.

If you can definitely set a lower limit together with an upper limit,
then you have essentially pinned down existence. For a photon, we have
no way to establish a lower limit for mass, so it must be the lowest
possible value allowed, which is zero.

whht is the acuracy of those measurments of upper limit
littl eparrot ??

no need for those measurments
the photon has mass theoretically and based on the experimental formula
E=hf while h has mass
got it moron physicist
you dont understand even how a physical formula is built !!!
