It would be interesting as well to look at this geometry from a perspective of how such an object would unfold.

The shape reminded me of a flexagon.

Good article.

presentation of the idea at SUSY2013

He seems to have lineage as a political refugee of Iranian heritage.

Nima Arkani-Hamed is a professor of physics at Harvard University. His father is a physicist who openly spoke against the Iranian Revolutionary Guard after the Iranian revolution in 1979. In fear for their lives, his family fled through the Turkish border on horseback in 1981, tearing up their passports as they cross the border. Nima's family emigrated to Canada where Nima finished high school and attended the University of Toronto as an undergraduate. He received is Ph.D. from Berkeley in 1997 and took a research position at Stanford before moving back to Berkeley two years later for a faculty position. The return was short-lived as Harvard snatched him up in 2001.

Nima is considered the greatest theoretical particle physicist of his generation. Despite his youth, he has become a leader in the field, creating subfields with each new idea. He now splits his time between studying fundamental issues with quantum theories of gravity and hands-on contributions to understanding in detail what we see at the LHC.

Yes. It all makes sense.

The article you just read meant something different beforehand.

I'm thrilled to see this shift from the Kaluza/Klein compactification models (string theory et al) to higher dimensional dynamics.

Another recent article was considering higher dimensional geometry in lieu of the big bang/inflationary model. And this particular article is running directly towards Max Tegmark's Level IV parallel universe model, roughly that what we experience in 4D is a manifestation of mathematical structures which actually do exist outside of space and time.

P.S. Wesson is a pioneer physicist in higher dimensional dynamics. His theories suggest a higher time-like dimension, that what we observe as reality in 4D could be as little as a single particle in a higher dimension, multiply imaged 1080 times.

And, of course, he also proposed that physical death in that geometry could simply be a phase shift.

I just keep thinking, “If they continue to tumble this problem around, they will eventually see it as the effect of phase shifts in the variable expressions of dimension space and dimension time, causing the ‘tensions’ between the expressed continua and the about to be expressed” ... but then, I'm a dreamer, and my tensor calculus is not so sharp anymore.

“In a sense, we would see that change arises from the structure of the object,” he said. “But it’s not from the object changing. The object is basically timeless.”

Unmoved mover anyone?

Same concept behind Brillouin Zones and reciprocal lattice space.

Hang in there, dear MHGinTN, no telling what will happen next. I would have never guessed they'd be thinking in these terms at this time.

Fascinating, thank you! Never heard of Nima Arkani-Hamed before I ran across this article. I’m not likely to forget him now!

Lol, I saw that the other day. Almost posted it myself, but didn’t know what kind of reception it would get here. So, thanks! I think it’s hilarious.

Did you see this one? Totally different topic, but in a similar vein and pretty funny.

Me too!!!

I'm fascinated by the ideas that space and time are not "fundamental" properties of the universe; rather they are emergent properties; and that locality and unitarity are not fundamental aspects of nature. Also that the amplituhedron geometry hints "at an underlying, coherent mathematical structure behind quantum field theory," indeed behind/beyond 4D spacetime itself.

Revolutionary ideas! It will be fascinating to see how they play out.

Indeed! I’m looking forward to the next advance in this line of thinking, dearest sister in Christ!
