The number of possible chess games (the Shannon number) is around 10^120. The number of atoms in the observable universe is only about 10^80. You could play a unique chess game every second since the Big Bang and never repeat—not even close.

Scientists calculated the average color of all light in the observable universe. It's a beige shade officially named "Cosmic Latte." The universe used to be bluer when it was younger—it's slowly getting more red as stars age and die.

Humans share about 25% of their protein-coding genes with bananas—the ancient "housekeeping" genes essential for all cellular life. You share 85% with mice, 96% with chimps, and surprisingly much with slugs. The genetic code of life is so conserved that we are essentially variations on a 4-billion-year-old theme.
