How do you think will the result be if the following experiment were to be done?
The experimental setting is this.
Think a large vacuum chamber with a pane through which the interior can be seen.
Assume there is a desk in the vacuum chamber.
And place on the desk a soft air tight bag of about 1 litter capacity made of electrical conductor skin.
Connect an optical glass fiber with the inlet of the bag.
Connect the other end of the glass fiber with a powerful laser generator.
For the initial condition, assume that the interior of the chamber and the interior of the bag are both complete vacuum, so that the bag should be placed on the desk in a state of completely squashed, flat shape.
Finally assume for simplicity that the electrical conductivity of the skin of the bag is infinite, so that we can neglect the possible joule heat dissipation.
Now let us begin the experiment.
It is simple. We will only just switch on the laser generator.
Then what do you think will happen?
Answer 1: There will be no change in the chamber, even if we increase the laser power.
Answer 2: The skin of the bag will begin to shine, but the shape of the bag remains to be squashed state yet.
Answer 3: The bag will be inflated by the inflow of momenta of photons from the laser equippment.
Come on! The problem is that simple. How do you think? How do you think?
