The last week or so, I’ve been feeling frustrated and angry (and hence, depressed) about people and politics (and bad television adaptations and Big Tech companies), but the numerologist in me finds a date like 4-4-24 hard to resist. Two fours in twenty-four; how can I not post something?
Because I’d rather curl up on the couch and read until I get over myself, this will be a short one (famous last words, I know).
In fact, it’s a (very) short story I wrote back in 2008.
This week I’ve focused on the relativity of time under motion, and we’ve seen that moving very fast allows “time travel” into the future. Very handy if you don’t mind the one-way trip. What’s more, a spaceship capable of such a flight is physically possible, so it’s a “time machine” we know works!
On Monday I described how fast-moving, but short-lived, muons created high in the atmosphere live long enough to reach the ground due to time dilation. That’s just one place we see Special Relativity actually working exactly as Einstein described. For another, fast-moving particles at CERN have decay times showing they, too, have slow clocks.
As we’ll see today, light’s behavior requires time appear to run slower!
