The “area law” says that a black hole’s surface area cannot decrease over time

Huge star, 25,000 light years away, dims by 97% then slowly returns to former brightness
Jupiter, Saturn and numerous giant exoplanets discovered to date consist mostly of hydrogen and helium. In 1977, planetary scientists predicted the existence of helium rain layer inside such planets. However, achieving the experimental conditions necessary to validate this hypothesis hasn’t been possible — until now.
