A Quanta Magazine article explaining the holographic principle in physics is being discussed on Hacker News. The idea is that gravity in a volume of space can be described by information encoded on that volume's boundary, as in the AdS/CFT correspondence, suggesting three-dimensional reality may emerge from lower-dimensional information. Commenters on the post are debating what this implies about the fundamental nature of space, time and whether reality is a projection.

Attorney General Todd Blanche defended the White House's decision to bar a news outlet from press access, telling reporters that covering the president is 'a privilege, not a right'.
