The TV series Fringe first premiered on the Fox network in the United States on September 9, 2008. It was groundbreaking Sci-Fi for the time, bringing what’s possible to the forefront of entertainment. Even to this day, some of the science fiction concepts are still plausible. Other concepts have been realized.

Fringe science – multiple worlds, a multiverse concept back in 2008 was still penetrating our social sphere.  August 12th, 2008, The (Multi) Universe(s), a conversation with Radiolab discussing parallel universes and the multiverse with Dr Brian Greene made a difficult concept easier to grasp. Listen here.

In short, as long as the [multi] universe is infinite, the science checks.  Great podcast. The Fringe TV show depicts alternate worlds distinguished by quasi harmonics, resonating quantum frequencies. Thinking how quantum strings exist and measuring them didn’t think it was a good basis for our multiverse compass.  Not practical. Better yet, as Dr Bishop put it, the physics are just different from one world to another.  Maybe physics, a universal constant that almost any being are able to calculate like PI?  The 3.14159… “universal” constant may change between universes, and PI calculated in one world is different for N decimal places.  Perhaps some other physics “universal” constants change? 

Fringe TV show explains how the two different worlds are intertwined with each other, and can be uniquely identified.

In the sci-fi television series Fringe, the Prime Universe (Blue-verse) and the Alternate Universe (Red-verse) occupy the exact same physical space but are dimensionally separated because they vibrate at different quantum frequencies.

The character Dr. Walter Bishop, explains that everything in existence is constantly vibrating. Because the two universes have different fundamental frequencies, they are completely invisible and intangible to one another under normal conditions.

Need to determine what is a universal physics constant that may change, and is as easy to calculate, to observe, so easy a layman could observe / measure it. I’d imagine calculating the universal constant is step one, and the delta between two universes in the multiverse would need to be determined.
