How's about this for a torch then?
Black Bullet X - 1.000.000 Lux/Candela
I wonder if you can pop balloons with it.

I can’t access the link but beware. There are so many items on the market with false claims about candle power and lux. It seem to be an advertising trick to use 1,000,000 candle power that means FA.Originally posted by zeitghost View Post"A people that elect corrupt politicians, imposters, thieves and traitors are not victims, but accomplices," George Orwell -
If you shined that up at a cloud
then moved it quickly, the spot on the cloud would move across
if the cloud were high enough, and you flicked it fast enough, the spot could travel at many times the speed of light
but I thought that was impossible

Why don't you work out how fast you would need to flick it, based on shining a laser at the moon say?Originally posted by EternalOptimist View PostIf you shined that up at a cloud

The spot is not actually a "thing" and so it can move as fast as it likes. What is moving is a flow of photons from the torch to the distant object and back. These will not be moving faster than light and so no laws are broken and all is well with the universe.Originally posted by EternalOptimist View Post
Edit to point out that the spot can move as fast as it likes because it doesn't actually move.Comment
