All Atoms Fall Alike: A Cosmic Verdict ⚡ экспресс
Original: "In-orbit Test of the Weak Equivalence Principle with Atom Interferometry"
A space test with atoms confirmed: gravity pulls everything equally, to within one ten-millionth.

On board the Chinese space station, two types of rubidium atoms were dropped in zero gravity—did they fall equally? The experiment showed: yes, to within one ten-millionth. This is the most precise quantum test of the equivalence principle in space, paving the way for ultra-sensitive gravitational navigation.
🎯 Galileo probably never actually dropped balls from the tower. But modern physicists had to toss atoms in space: on Earth, free fall would last less than a second, but in zero gravity it's a few precious moments.
🎬 In the movie 'Interstellar,' gravity allows communication across dimensions. Experiments like this are a real step toward understanding how the fabric of the universe curves.
