NASA'S PICTURE FOR THIS DAY

COSMIC MESSAGE

The Holographic Principle suggests a surprising idea: the information content of a region depends not on its volume, but on the area of its bounding surface. This unproven principle challenges our intuition about how information is stored in the universe. It's a concept that pushes the boundaries of theoretical physics.
