#40: Spinning Laser
This is a very old question for me.
If you take a LASER, I know that the very cool feature it has is being collimated, meaning the beam doesn't spread out like a flashlight.
If you spin a laser, with speeds comparable to the speed of light c, does it get more collimated?
Is this of any use, if you wished to send a laser beam to another planet?
