On July 9, 2025, Earth spun faster than usual, enough to make the day 1.6 milliseconds shorter than the standard 24 hours. Add a leap day every 4 years, except: Years divisible by 100, unless they’re also divisible by 400, giving 365.2425 days/year, which is very close to the real 365.2422.

JWST’s Advanced Deep Extragalactic Survey (JADES) analyzed 263 galaxies from the early universe and revealed a significant asymmetry: roughly 66% spin clockwise, while only about 33% rotate counterclockwise. Does this mean the universe is in a spinning black hole? academic.oup.com/mnras/articl...
