Is the Universe a Giant Hologram?
Tuesday, February 10th, 2009
This theory contends that the interior of the universe is simply a replication of the information on its outer surface. And since the three-dimensional (okay, four-dimensional but let’s keep this simple) interior can hold much more data than the two-dimensional surface, the internal information has a granularity, sort of like what happens when you expand a bitmap image. It sounds pretty bizarre, but there are mathematical and experimental results that may back it up. The “blurring” threshold is believed to be about 10-16 meters, which is measurable by existing equipment.

Update: The New Scientist has gone to a paywall. Ars Technica has an article that explains this concept.
Back in 1961, astronaut Gus Grissom took two rolls of dimes into orbit on the Liberty Bell 7 spaceflight. Upon returning to Earth, Grissom’s capsule sank in deep ocean waters and he was forced to leave the coins behind. The capsule was retrieved in 1999, and the dimes now reside in a space museum.
