Multidimentionality

• Do we really live in only three dimensions? String theory and extra dimensions

• Hyperdimensional computing: A fast, robust, and interpretable paradigm for biological data

Michael Pravica, a physics professor at the University of Nevada, has proposed an intriguing theory that human consciousness may stem from hyperdimensional realms. This concept suggests that our brains' consciousness might originate from dimensions beyond the familiar four (height, length, width, and time). Pravica's theory is influenced by the idea of hyperdimensionality, which posits the existence of more spatial dimensions than those we encounter daily. Pravica's proposal has sparked debate within the scientific community. While some see it as a groundbreaking perspective that could shed light on the mystery of consciousness, others, like Stephen Holler, an associate physics professor at Fordham University, caution against attributing gaps in our scientific understanding to supernatural cause. A new theory to explain human consciousness has suggested it comes from hidden dimensions and is not just brain activity. A physicist claimed that we plug in to these invisible planes of the universe when making art, practicing science, pondering philosophy or dreaming, and this could explain the phenomenon that has evaded scientific understanding for centuries. Michael Pravica, has based the wild idea on hyperdimensionality, the idea that the universe is made up of more dimensions than just the four we perceive: height, length width and time.

Multiverse required

'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.

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. Starting in the 1970s, Deutsch had walked backwards into becoming a pioneer in the field of quantum computing, less out of interest in the technology itself, than his desire to test the multiverse theory.

Astrophysicist turned science writer Ethan Siegel blasted Google over the claim, accusing them of 'conflating unrelated concepts, which Neven also ought to know.'

'Neven has conflated the notion of a quantum mechanical Hilbert space, which is an infinite-dimensional mathematical space where quantum mechanical wavefunctions "live," with the notion of parallel universes and a multiverse,' Siegel argued Friday.
