Scientists Simulate Fourth Spatial Dimension In New Quantum Hall Experiments

[T]ime has often been considered as the fourth dimension of space, with three spatial dimensions where one can go up or down, left or right, or forward or backward. But two new papers published in the journal Nature suggest that there might be a fourth spatial dimension, one that could possibly suggest previously undiscovered directions of motion.

As detailed in a report from Gizmodo, two separate teams of researchers created their own two-dimensional setups, with one team using ultra-cold atoms and the other one working with waves of light. While the studies produced varying results, the findings complemented each other, as they both exhibited examples of the so-called “quantum Hall effect” in four-dimensional form.

“Physically, we don’t have a 4D spatial system, but we can access 4D quantum Hall physics using this lower-dimensional system because the higher-dimensional system is coded in the complexity of the structure,” explained Penn State University professor Mikael Rechtsman, lead author of one of the new studies, in an interview with Gizmodo.

If they find one more dimension, they can start a band.

[BenLurkin]

Is this somehow related to string theory?

I'm glad he explained it.

Would that be a string band?

[BitWielder1]

I could use a fourth dimension for storage.

Ha!

Wasn’t this the plot to the Netflix series “Stranger Things”?

Spooky hotdog thrown a distance.

Probably a rubber band.

It’s nothing new. Donald Trump and Steve Bannon were playing 4D chess long at least 18 months before this item hit the news media.

Thanks BenLurkin.

Most three year olds comprehend time. It seems Quantum Physics is based more on research grants than on anything else.

When the being who wrote upon the wall in Palace PArty Central in Daniel five, that being stood in a spacetime coordinate system unsensed by the partiers or the King. Only the hand reached into our coordinate system, briefly. It’s real, it has existed all along, and now we’ve given it a name!

[Dr. Bogus Pachysandra]

Spaghettification!

[Kickass Conservative]

Back in the 60’s both The Outer Limits and The Twilight Zone tackled this problem with differing results.

[BenLurkin]

I still don’t understand the difference between Quantum Hall and Huntz Hall.

Good name for a band
