The New York Times has an answer.
| quote | In an experiment that ticks most of the mystery boxes in modern physics, a group of researchers announced on Wednesday that they had simulated a pair of black holes in a quantum computer and sent a message between them through a shortcut in space-time called a wormhole.
Physicists described the achievement as another small step in the effort to understand the relation between gravity, which shapes the universe, and quantum mechanics, which governs the subatomic realm of particles.
“This is important because what we have here in its construct and structure is a baby wormhole,” said Maria Spiropulu, a physicist at the California Institute of Technology and the leader of a consortium called Quantum Communication Channels for Fundamental Physics, which conducted the research. “And we hope that we can make adult wormholes and toddler wormholes step-by-step.”
In their report, published Wednesday in Nature, the researchers described the result in measured words: “This work is a successful attempt at observing traversable wormhole dynamics in an experimental setting.”
The wormhole that Dr. Spiropulu and her colleagues created and exploited is not a tunnel through real physical space but rather through an “emergent” two-dimensional space. The “black holes” were not real ones that could swallow the computer but lines of code in a quantum computer. Strictly speaking, the results apply only to a simplified “toy model” of a universe—in particular, one that is akin to a hologram, with quantum fields on the edge of space-time determining what happens within, sort of in the way that the label on a soup can describes the contents.
To be clear: The results of this experiment do not offer the prospect anytime soon, if ever, of a cosmic subway through which to roam the galaxy like Jodie Foster in the movie “Contact” or Matthew McConaughey in “Interstellar.” |

"YOUR MOM!"
(not that I'm referring to YOUR MOM, It's just a great answer to SO MANY questions!)

YOUR MOM might be the crumbiest wormhole ever seen......but certainly nowhere near the smallest !!
BTW....
If grandma had plastic all over the couch...it's because grandma was a squirter and grandad knew what he was doing....
Soooo....why isn't your couch covered in plastic.

So, did they just program the computer to give them the answer they wanted?
Are scientists just making stuff up now?

The institutional affiliations of the eight people named as authors: Harvard, MIT, Caltech, Fermilab and Google.
FWIW.
I wonder if any of them are Freemasons.

More proof quantum computers are complete bullshit.

I agree, (come on - they look like something straight outta Dr. WHO, and you're tellin' me no amateurs/hobbyists have been able to make one?

| quote | | Recent headlines about physicists having created a wormhole using Google’s quantum computer are misleading. Not only did they not create a wormhole in spacetime, the kind that Einstein’s equations suggest is possible, they didn’t even create a hologram of a wormhole, as the original Nature article claimed. Martin Bauer explains what the Sycamore experiment was actually all about. |
