1) You obviously don't know anything about almost perfect
reflectivity of advanced coating materials, like the ones
used in the mirrors of the LIGO instrument, which reflect
with ultra-high effectivity 40 Watts lasers, which are
reflected 18,750 times to obtain the cumulative power
of 750,000 watts before the composite beam reach the
detector. Make some research on this.

750,000 Watts?!  That's ridiculous! :-))

2) I see that you are in denial of what you read.

Pot, kettle, black.

I wrote CLEARLY that the weight of each cavity is 2.00 grams.

Which would quickly burn up because of the losses.

They are done with very thin composite materials, much more
advanced than acrylic mirrors, in the order of 99.999+ % of
reflectivity. Make your calculations again.

Make yours.

I don't know why you are writing about 11 Kg balls,

Then you're obviously not understanding what I wrote, and
you're in denial of the physics involved.

Maybe, it will be an eye-opener for your stubbornness.

Please, read ALL WHAT I POST, because you don't.

Au contraire.  I did.

I'm an EE,

So am I ... and a physicist.

and I don't write idiocies when dealing with details of
experiments involving technology.

Apparently, you do :-)
750,000 watts?!!! :-))

I'm very careful with numbers.

But you ignore physics.  LIGO does NOT build up 750,000 Watts!
It's an interferometer.  The light doesn't go back and forth
between mirrors 18000 times.  It is split between two arms,
goes 4 km down each arm, is reflected by mirrors at the end,
comes back and the two beqams go to a detector.  End of story.
You are conflating LIGO with something completely different.
You are speculating a build up of energy inside your little
ball.  With 99.9999% reflectivity each time the light bounces
off the wall, CALCULATE how many times that light must bounce
in 72 hours.  What's left will be a skinny zero.  CALCULATE
where all that lost energy goes!  The only answer is heat.
Your little ball goes poof!

If you don't like the idea, write numbers and considerations
that make sense, instead of posting deceiving/incorrect data,
which has no support based on references. I post data WITH
REFERENCES, citing links.

I use PHYSICS.  You can get the info out of a physics textbook.
I gave the results of my calculations.  You completely missed
the fact that your little ball would become a sphere of flame.
I suggested an alternative that avoided that catastrophe and
followed the science of it.

Reread what I wrote and find out why I suggested an 11 kg ball.
Try to understand that heat is E = mc^2 energy, too.  Since
your little ball gets trashed because it overheats, USE the heat
for the experiment.  Use the 5W laser to heat the ball.
I also showed what would happen if you reduced the size of
the ball (poof!).  It's still ridiculous because the proposed
scales is too fragile to handle the weight.
Too bad.  Nice ideas, but a good physicist, doing a few simple
calculations would have seen right off that it wouldn't work.
