Current "state of the art" weighting technology (expensive) can measure
about 1 nanogram of MASS.
So your ignorance of physics extends to experimental technique as well.
FYI, comparing standard kilograms can be done at present to about 10^-9,
so to microgram accuracy.
I asked ChatGPT this question:
Why, for heavens sake? To dumb to think for yourself?
But one can easily estimate orders of magnitude:
c^2 = 9x10^16 joule/kg, so at 10^-9 accuracy
you need to add 9x10^7 joules to a standard kg
for it's relativistic mass increase to be detectable.
This is about 20 kg of TNT equivalent.
So for the kiddies: don't try this at home,
(and draw your own conclusions)
