Inverse square applies to omnidirectional things, a decently collimated laser will hold power over the length of a room.
Of course, I was being stupid.
I am being nice when I say this, but the problem is that you are asking a question that 'depends' ....like a question of a similar nature would be something like, (and the following question is off the top of my head...), "WHAT CAN STOP A "RAZOR SHARP WAR AXE" from chopping something?!!!!?????"
A 100 foot thick log would do it....or if the person missed its target (the log...), or if the axe handle was defective and broke before it hit the target, or if the target ran away faster than the man swinging the axe (assuming a man swings the axe ). If a machine swung the axe, then it would definately not chop anything, because the machine has a tiny little clock motor that is powering the swinging action
?? why did I answer this?
