Google Quantum Computer and Multiverse & NASA Parallel Uni where time runs abckward

Not sure I can even follow this but these sure are interesting times we live in. I've been following their quantum computing efforts and they seem to be accelerating rapidly

OT - sort of, we spent a day in Oxford England on Friday. amazing place. The newest college there is 5 years old and entirely dedicated to AI. It was a physisicist from Oxford quoted below that discussed how successful quantum computing would confirm the existence of the multiverse.

One can apply to Oxford or to Cambridge, but not to both. List of Oxford graduates that became world leaders of governments and industry is amazing. Cold blustery day but still learned a lot about the town.

Will someone smarter than me break down how that all works together?


Google says it accessed parallel universes with its new supercomputer

Google's quantum computing breakthrough on Monday has left the physicist who heads the project a believer in 'the idea that we live in a multiverse.'

'Willow,' the tech giant's new quantum chip, succeeded in solving a computational problem so complex it would have taken today's best super-computers an estimated 10 septillion years to solve it — vastly more than the age of our entire universe. But Google said its new quantum computer solved the puzzle 'in under five minutes.'

Calling Willow's performance 'astonishing,' the leader and founder of Google Quantum AI team, physicist Hartmut Neven, said its high-speed result 'lends credence to the notion that quantum computation occurs in many parallel universes.'

Neven credited Oxford University physicist David Deutsch for proposing the theory that the successful development of quantum computing would, in effect, affirm the 'many worlds interpretation' of quantum mechanics and the existence of a multiverse.

 

I was trying to read some of his quotes while visiting the school where he teaches..no luck. Thinking about getting the book but it will likely be over my head too.


The Fabric of Reality: The Science of Parallel Universes-and Its Implications: Deutsch, David: 9780140275414: Amazon.com: Books

For David Deutsch, a young physicist of unusual originality, quantum theory contains our most fundamental knowledge of the physical world. Taken literally, it implies that there are many universes “parallel” to the one we see around us.

This multiplicity of universes, according to Deutsch, turns out to be the key to achieving a new worldview, one which synthesizes the theories of evolution, computation, and knowledge with quantum physics.

Considered jointly, these four strands of explanation reveal a unified fabric of reality that is both objective and comprehensible, the subject of this daring, challenging book.

The Fabric of Reality explains and connects many topics at the leading edge of current research and thinking, such as quantum computers (which work by effectively collaborating with their counterparts in other universes), the physics of time travel, the comprehensibility of nature and the physical limits of virtual reality, the significance of human life, and the ultimate fate of the universe. Here, for scientist and layperson alike, for philosopher, science-fiction reader, biologist, and computer expert, is a startlingly complete and rational synthesis of disciplines, and a new, optimistic message about existence.

 

I didn't see anywhere that they claimed it was proven, just that the results lends credence to what others have postulated.

Are parallel universes physical or are we all living in the matrix?

do parallel universes occupy the same space, just at different times or in some other different dimesnion?

 

ok..this is getting even deeper. Now NASA scientists say they have detected a parallel universe where time runs backward

something tells me we are going to learn that time travel is a thing and that is who has been visiting...

NASA scientists detect parallel universe ‘next to ours' where time runs backwards

In the icy expanse of Antarctica, a groundbreaking experiment has uncovered astonishing evidence of a parallel universe-one that operates on completely opposite rules of physics. This discovery could redefine our understanding of reality and the cosmos. NASA's Antarctic Impulsive Transient Antenna (ANITA) experiment was designed to detect high-energy cosmic particles. Suspended by a giant balloon above Antarctica's ice, the antennas scanned the cold, radio-noise-free environment for unusual signals. ANITA's findings went beyond its mission, revealing something extraordinary.

High-energy cosmic particles typically travel downward from space, as Earth's solid core blocks their upward trajectory. However, ANITA detected particles seemingly rising from the ground-an anomaly suggesting they were traveling backward in time. This baffling phenomenon defied conventional physics.
Lead researcher Peter Gorham of the University of Hawaii theorized that these particles, tau neutrinos, might have transformed into other types of particles to bypass Earth's dense matter. Such an occurrence is statistically improbable, yet ANITA observed this anomaly multiple times.

The most straightforward explanation, according to Gorham, is that the Big Bang created not just our universe but also a twin universe where time flows in reverse. Inhabitants of this "anti-universe," if they exist, might perceive our world as the one running backward. While the discovery has sparked excitement, many researchers caution against drawing definitive conclusions. Astrophysicist Geraint Lewis and others argue that alternative explanations, such as undiscovered particle behaviors, could also account for ANITA's findings.

While ANITA's findings are not yet conclusive proof of a parallel universe, they have opened the door to exciting new possibilities about our reality. Whether this discovery rewrites the laws of physics or unveils a twin universe, it reminds us of how much we still have to learn about the cosmos.

 

Well I know little or nothing and I started the thread so that means I am following the rules. That is totally unacceptable as I have a reputation to maintain. I will try and do better...

 

now quantum mechanics are being directly related to gravity...seems like a lot of stuff coming together to generate something bigger soon..


Historic discovery connects quantum mechanics with gravity

Scientists at Purdue University have reached a groundbreaking milestone with an innovative experimental setup involving levitated fluorescent nanodiamonds. These tiny diamonds, suspended in a vacuum, spin at astonishingly high speeds while emitting and scattering multicolored light.

Led by Professor Tongcang Li, the research represents a significant step forward in the study of rotating quantum systems and levitodynamics. Published in Nature Communications, the findings have been praised by reviewers as “a groundbreaking moment” and “a new milestone for the levitated optomechanics community.”

Li, a member of the Purdue Quantum Science and Engineering Institute, highlighted the importance of their work. "These levitated diamonds contain spin qubits that enable us to conduct precise measurements and probe the intriguing connection between quantum mechanics and gravity," he said.

The universe might actually contain 3 time dimensions and only 1 space dimension

In the proposed framework, three dimensions act as time dimensions, while one remains spatial. This shifts the very essence of velocity and kinematics. The researchers prove that Einstein’s postulate of light’s constant speed still holds true for superluminal observers.

As Dragan notes, this approach integrates the quantum principle of superposition, where particles move along multiple paths simultaneously, transforming our understanding of determinism.
.........................
The inclusion of superluminal observers extends the postulates of quantum theory and relativity into uncharted territory. By bridging these pillars of modern physics, the research challenges the notion that quantum mechanics’ principles are fundamental and indivisible. Instead, it posits that quantum behavior naturally emerges from extended relativity in a four-dimensional spacetime.

As Turzyński puts it, this integration transforms the deterministic classical world into one governed by indeterminacy and quantum fields. The field-theoretic framework becomes the only viable description of a universe that includes superluminal observers. This perspective reshapes our understanding of symmetry, motion, and the fabric of reality itself.
