What's the fastest thing in the universe?
Chris Smith put this question to physicist Stuart Higgins...
Chris - Well, I would say a photon is the fastest object in space as it's going at the speed of light. Would you concur Stuart?
Stuart - I would indeed. A photon, the speed of light is the fundamental speed limit in the universe.
fast -> swift. Glue and seatbelts are fast, not liht.
The obvious answer is of course light. I notice that the answer accepted was a Photon.
Liht doesn't travel (< travail < trepale); one travels on foot or by oar. Immassive quanta are waves. Speed has nothing to do with fastness. Black holes don't exist but break special relativity, conservation of momentum, and optics. alysdexia, Sun, 17th Jan 2016

So whilst the rest of us make the journey from A to B by travelling on a train, alysdexia spends his waking hours (journee) by working (travaillant) on it. Wow! A really pedantic ticket inspector!
