Canadian science communicator Derek Muller has a great new video on his YouTube channel Veritasium explaining the physics of contraptions meant to go faster than light. He shows how things get weird really fast in these situations, and explains why the speed of light – 186,000 miles per second (300,000 km/sec) – appears to be our universe’s ultimate speed limit. You’ll enjoy all six minutes of it. Way to go, Derek!
Thank you, Robert Rudnik for the heads up!
Bottom line: Why we haven’t been able to build – or even conceive of – a contraption that goes faster than light.
