“Once we introduce the possibility of applying the quantum principle to the universe, we are forced to consider parallel universes”*…




In the Antarctic, things happen at a glacial pace. Just ask Peter Gorham. For a month at a time, he and his colleagues would watch a giant balloon carrying a collection of antennas float high above the ice, scanning over a million square kilometres of the frozen landscape for evidence of high-energy particles arriving from space.

When the experiment returned to the ground after its first flight, it had nothing to show for itself, bar the odd flash of background noise. It was the same story after the second flight more than a year later.

While the balloon was in the sky for the third time, the researchers decided to go over the past data again, particularly those signals dismissed as noise. It was lucky they did. Examined more carefully, one signal seemed to be the signature of a high-energy particle. But it wasn’t what they were looking for. Moreover, it seemed impossible. Rather than bearing down from above, this particle was exploding out of the ground.

That strange finding was made in 2016. Since then, all sorts of suggestions rooted in known physics have been put forward to account for the perplexing signal, and all have been ruled out. What’s left is shocking in its implications. Explaining this signal requires the existence of a topsy-turvy universe created in the same big bang as our own and existing in parallel with it. In this mirror world, positive is negative, left is right and time runs backwards. It is perhaps the most mind-melting idea ever to have emerged from the Antarctic ice ­­– but it might just be true…

Strange particles observed by an experiment in Antarctica could be evidence of an alternative reality where everything is upside down: “We may have spotted a parallel universe going backwards in time.”

As we consider our alternatives, we might recall that it was on this date in 1912, in his “Manuscript on the Special Theory of Relativity,” that Einstein first identified the fourth dimension as time… or so it is widely accepted.  Some physicists believe that Einstein was making a subtler– and much more complicated– suggestion, “x4 = ict”: that the fourth dimension, not “physical” like the other three, but emergent (in a way “understandable” as time) as the fourth dimension expands from the other three at the rate of “c.”

“There are two things you should remember when dealing with parallel universes. One, they’re not really parallel, and two, they’re not really universes.”*…




At Oak Ridge National Laboratory in eastern Tennessee, physicist Leah Broussard is trying to open a portal to a parallel universe.

She calls it an “oscillation” that would lead her to “mirror matter,” but the idea is fundamentally the same. In a series of experiments she plans to run at Oak Ridge this summer, Broussard will send a beam of subatomic particles down a 50-foot tunnel, past a powerful magnet and into an impenetrable wall. If the setup is just right — and if the universe cooperates — some of those particles will transform into mirror-image versions of themselves, allowing them to tunnel right through the wall. And if that happens, Broussard will have uncovered the first evidence of a mirror world right alongside our own.

“It’s pretty wacky,” Broussard says of her mind-bending exploration.

The mirror world, assuming it exists, would have its own laws of mirror-physics and its own mirror-history. You wouldn’t find a mirror version of yourself there (and no evil Spock with a goatee — sorry “Star Trek” fans). But current theory allows that you might find mirror atoms and mirror rocks, maybe even mirror planets and stars. Collectively, they could form an entire shadow world, just as real as our own but almost completely cut off from us…

If the “mirrorverse” exists, upcoming experiments involving subatomic particles could reveal it: “Scientists are searching for a mirror universe. It could be sitting right in front of you.”

As we reflect of reflections, we might recall that it was on this date in 64 CE that the Great Fire of Rome began, ultimately destroying much of the Imperial City.  The fire began in the slums of a district south of the Palatine Hill.  The area’s homes burned very quickly and the fire spread north, fueled by high winds; it raged out of control for three days.  Three of Rome’s 14 districts were completely razed; only four were untouched by the conflagration.  Hundreds of people died in the fire and many thousands were left homeless.

Legend has it that the Emperor Nero fiddled while the city burned.  But the fiddle did not even exist at the time (Nero was an adept of the lyre), and he was actually 35 miles away in Antium when the fire broke out.  What is clear is that he blamed “the Christians” for it.

“Our Universe is simply one of those things which happen from time to time”*…


The “many-worlds interpretation” is a reading of quantum mechanics that implies that all possible alternative histories and futures are real, each representing an actual “world” (or “universe”). That’s to say, the hypothesis holds, that there is a very large—perhaps infinite—number of universes, and that everything that could possibly have happened in our past, but did not, has occurred in the past of some other universe or universes…  All very well, but what does it mean?

Happily, Sean Hartter is here to illustrate:  his “Alternate Universe Movie Posters” give one a peek at one-sheets one might have seen if one lived a couple of universes over…

Many, many more glimpses across the folds of space-time at Sean’s site.

As we take a mulligan, we might send very carefully-crafted birthday greetings to Jacques de Vaucanson; he was born on this date in 1709.  A mechanical genius, de Vaucanson invented a number of machine tools still in use (e.g., the slide rest lathe) and created the first automated loom (the inspiration for Jacquard).  But he is better remembered as the creator of extraordinary automata.  Among his most famous creations:  The Flute Player (with hands gloved in skin) and The Tambourine Player, life-sized mechanical figures that played their instruments impressively.  But his masterpiece was The Digesting Duck; remarkably complex (it had 400 moving parts in each wing alone), it could flap its wings, drink water, eat grain– and defecate.

Sans…le canard de Vaucanson vous n’auriez rien qui fit ressouvenir de la gloire de la France.  (Without…the duck of Vaucanson, you will have nothing to remind you of the glory of France)
