This is a physics and astrophysics puzzle. It's meant to be fun to solve with a group of physicists, so please print one out and hang it up in your department hallway or breakroom or lab; I'd love to hear about it if you do. (Based on a puzzle originally written for the
2019 MIT Mystery Hunt. See
the original acrostic form and
other physics puzzles here.)
If you have trouble following an arrow, the SVG below has some mouseover highlighting and is searchable.
The puzzle is intended to be solved on a large poster-sized print. You can purchase a poster from my Zazzle.com store (any income here donated to MIT Mystery Hunt). If you do have a poster printer, download and print your own:
