- Avi Loeb, astronomy’s resident unhealthy boy, suggests the universe might have been created in a laboratory.
- Our supposed creators, Loeb writes in an op-ed printed in Scientific American final 12 months, might have developed the know-how wanted to assemble “child universes” able to producing life.
- He additionally introduces a brand new classification system for superior civilizations.
Might our universe have been created in a petri dish? Avi Loeb appears to assume so. The Harvard astronomer posits {that a} greater “class” of civilization might have conjured up our universe in a laboratory far, distant.
“Since our universe has a flat geometry with a zero internet power, a complicated civilization may have developed a know-how that created a child universe out of nothing via quantum tunneling,” Loeb writes in an op-ed printed by Scientific American final 12 months.
This idea, he suggests, would unite two seemingly reverse notions: the concept the next energy could be driving our destiny, and the secular idea of quantum gravity (a subject of physics that seeks to work gravity into the idea of quantum mechanics—one thing that, to the bane of physicists in all places, we haven’t been in a position to do but on Earth). Primarily, this idea hinges on a far-off superior civilization’s capacity to meld each quantum mechanics and gravity and subsequently establish and recreate the entire universe’s components. (Feels like lots of work, t0 be trustworthy.)
He additionally introduces a brand new approach of classifying precisely what makes a civilization superior—one which veers away from Soviet astrophysicist Nikolai Kardashev’s system, which organizes civilizations based mostly on the quantity of power they generate and eat.
In accordance with Kardashev, Sort I civilizations—greetings, Earthlings!—are solely superior sufficient to make the most of the starlight that reaches their planet (4×1012 watts), whereas Sort II civilizations have mastered the flexibility to completely harness their host star’s energy (4×1026 watts). Dyson sphere, anybody? Sort III civilizations, the ultimate classification in his framework, are in a position to harness the entire power inside their galaxy (a whopping 4×1037 watts).
Loeb, against this, has devised a framework that breaks superior civilizations down into courses based mostly on their capacity to “reproduce the astrophysical situations that led to its existence.”
Earthlings would fall into class C as a result of, as a “low-level” technological civilization, we’d not be capable of recreate our present situations ought to the solar abruptly die. (He suggests we would even fall into the class D class as a result of we’re actively destroying our solely residence.) However, class B civilizations, Loeb writes, are superior sufficient to recreate the situations by which they reside, impartial of their host star.
A class A civilization, like our proposed creators, would be capable of, say, generate massive quantities of darkish power and, as Loeb suggests, create “child universes,” or smaller universes managed by this greater civilization, that would doubtlessly spawn life. He additionally means that, attributable to competitors, just one superior civilization at a time would be capable of attain this stage of sophistication.
It’s a very, actually bonkers concept, but it surely is attention-grabbing to consider. And it brings up a set of intriguing questions: What makes a civilization actually technologically superior? Are we a complicated simulation? What may this “laboratory” appear to be, anyway?
