Albert Einstein spent a lifetime solving the riddles of the universe.
Thanks to his keen mind, we now have a much deeper understanding of how light, time, space, gravity, and mass are related.
Einstein spent so much time unraveling puzzles, it's no surprise that, many think, he came up with one of his own.
The "Einstein Riddle" isn't solved with math, just basic logic and deduction.
TED-Ed has made a video about the riddle, explaining the solution at the end and the best way to solve similar riddles.
