IT'S A BETTER FORMULATION
In this next quote, a theoretical physicist from Cambridge University explains that this concept of a Universe of space and time emanating from a single geometric form is a "better formulation."
“It’s a better formulation that makes you think about everything in a completely different way,” said David Skinner, a theoretical physicist at Cambridge University.
GIVING UP SPACE AND TIME
In this final quote from the very end of the Quanta Magazine paper, one of the authors of this study said it forces us to "give up space and time" as we now think of it.
Beyond making calculations easier or possibly leading the way to quantum gravity, the discovery of the amplituhedron could cause an even more profound shift, Arkani-Hamed said.
That is, giving up space and time as fundamental constituents of nature and figuring out how the Big Bang and cosmological evolution of the universe arose out of pure geometry.
“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.”
While more work is needed, many theoretical physicists are paying close attention to the new ideas.
The work is “very unexpected from several points of view,” said Witten, a theoretical physicist at the Institute for Advanced Study.
“The field is still developing very fast, and it is difficult to guess what will happen or what the lessons will turn out to be.”
LET'S GET A LOOK AT THIS GEOMETRY
This unified geometry has no actual space or time as we know it. Here is an accurate diagram of what it looks like from this same article.
SIR ROGER PENROSE WAS THE FIRST
The only noteworthy omission in this exceptional article is the fact that this concept is not actually a new idea.
Stephen Hawking's partner in developing the physics of the black hole, Roger Penrose, did most of the work in the 1970s.
In the book "The Nature of Space and Time," Penrose argues in favor of this new model — whereas Hawking defends the traditional idea of a "Big Bang."
This book was originally published in 1996, and emerged out of a debate between Penrose and Hawking at the University of Cambridge in 1994.
Arkani-Hamed and Trnka started with Penrose's idea and actually found a way to make it work.
In so doing, they took the staggeringly complex world of quantum physics — the actual paths traced by everything we've ever measured down there — and made it astonishingly simple.
THIS EXPLAINS THE ABUNDANCE OF "ZERO-POINT ENERGY"
Instead of the worn-out idea of "empty space," the further we zoom down into the quantum realm in an area — in any area — we will find an ever-increasing abundance of energy.
This is exactly what scientists have already discovered. On this NASA website, you can read the following quote:
Zero Point Energy (ZPE), or vacuum fluctuation energy are terms used to describe the random electromagnetic oscillations that are left in a vacuum after all other energy has been removed.
If you remove all the energy from a space, take out all the matter, all the heat, all the light… everything — you will find that there is still some energy left….
In simplistic terms it has been said that there is enough energy in the volume the size of a coffee cup to boil away Earth’s oceans. – that’s one strong cup of coffee!…
[For those hungry for tangible proof, read this last part of the excerpt as an optional "geekspeak" add-on:]
What evidence shows that it exists?
First predicted in 1948, the vacuum energy has been linked to a number of experimental observations.
Examples include the Casimir effect, Van der Waal forces, the Lamb-Retherford Shift, explanations of the Planck blackbody radiation spectrum, the stability of the ground state of the hydrogen atom from radiative collapse, and the effect of cavities to inhibit or enhance the spontaneous emission from excited atoms.
The name they gave this geometry was the "amplituhedron". Other physicists have called it a "positive Grassmanian." Here it is:
