An international study claims to have found first observed evidence that our universe is a hologram.

What is the holographic universe idea? It’s not exactly that we are living in some kind of Star Trekky computer simulation. Rather the idea, first proposed in the 1990s by Leonard Susskind and Gerard ‘t Hooft, says that all the information in our 3-dimensional reality may actually be included in the 2-dimensional surface of its boundaries. It’s like watching a 3D show on a 2D television…

Just when one thought that things couldn’t get any stranger: “Scientists Find First Observed Evidence That Our Universe May Be a Hologram.”

Pair with this piece on recent experimental confirmation of what Albert Einstein called “spooky action at a distance.”

As we batten down the hatches, we might send shady birthday greetings to Fritz Zwicky; he was born on this date in 1898.  A distinguished astronomer who worked at Cal Tech most of his life, Zwicky is best remembered for being the first to infer the existence of “dark matter“: while examining the Coma galaxy cluster in 1933, he used the virial theorem to deduce the existence of what he then called dunkle Materie. Colleagues knew him as both both a genius and a curmudgeon. One of his favorite insults was to refer to people of whom he didn’t approve as “spherical bastards”– because, he explained, they were bastards no matter which way you looked at them.

“If you think this Universe is bad, you should see some of the others”*…

 

In cosmology as in so many branches of the scientists, theorist tend to get most of the attention.  But in the end, it’s experimentalists who covert hypothesis into knowledge.  Current theories suggest that our universe– which could be “the universe” or could be one of many– could be a hologram, a computer program, a black hole or a bubble—and, experimentalists suggest, there are ways to check…

Ponder their proofs at “What Is the Universe? Real Physics Has Some Mind-Bending Answers.”

As we practice our pronunciation of “billions and billions,” we might spare a thought for Ron Toomer; he died on this date in 2011.  Toomer began his career as an aeronautical engineer who contributed to the heat shields on NASA’s Apollo spacecraft.  But in 1965, he joined Arrow Development, an amusement park ride design company, where he became a legendary creator of steel roller coasters.  His first assignment was “The Run-Away Mine Train” (at Six Flags Over Texas), the first “mine train” ride, and the second steel roller coaster (after Arrow’s Matterhorn Ride at Disneyland).  Toomer went on to design 93 coasters worldwide, and was especially known for his creation of the first “inversion” coasters (he built the first coasters with 1, 2, 3, 4, 5, 6, and 7, loops).  In 2000, he was inducted in the International Association of Amusement Parks and Attractions (IAAPA) Hall of Fame as a “Living Legend.”
