New analysis shows a way to self-propel subatomic particles
Some physical principles have been considered immutable since the time of Isaac Newton: Light always travels in straight lines. No physical object can change its speed unless some outside force acts on it.
Flashes from faster-than-light spots may help illuminate astronomical secrets
(Phys.org)—If you sweep a laser pointer across the Moon fast enough, you can create spots that actually move faster than light. Anyone can do it.
