"Our Universe is Made Up of Indivisible Building Blocks --Like Tiny Atoms"

The start of the Universe should be modeled not as a Big Bang but more like water freezing into ice, according to findings by a team of theoretical physicists at the University of Melbourne and RMIT University in 2012 that could our revolutionized our understanding of the nature of the Universe. The key, they proposed, is to be found in the cracks and crevices common to all crystals.

"Albert Einstein assumed that space and time were continuous and flowed smoothly, but we now believe that this assumption may not be valid at very small scales," said Project lead researcher James Q. Quach, of the University of Melbourne school of physics. “A new theory, known as quantum graphity, suggests that space may be made up of indivisible building blocks, like tiny atoms. These indivisible blocks can be thought about as similar to pixels that make up an image on a screen. The challenge has been that these building blocks of space are very small, and so impossible to see directly.”

“Think of the early universe as being like a liquid,” Quach added. “Then as the universe cools, it ‘crystallizes’ into the three spatial and one time dimension that we see today. Theorized this way, as the Universe cools, we would expect that cracks should form, similar to the way cracks are formed when water freezes into ice.”

RMIT University research team member Associate Professor Andrew Greentree said some of these defects might be visible. “Light and other particles would bend or reflect off such defects, and therefore in theory we should be able to detect these effects."

These structures should have observable background-independent consequences, including scattering, double imaging, and gravitational lensing-like effects, the scientists wrote in their paper. The team has calculated some of these effects and if their predictions are experimentally verified, the question as to whether space is smooth or constructed out of tiny indivisible parts will be solved once and for all.

You may want to fix "quantum graphity" to "quantum gravity".

SO...no, it's quantum graphity. Google it.

I' of the opinion that it's actually something right in the middle of quantum gravity and string theory. Stringy blocks, perhaps.

Come on say it once and for all that we are inside a ultra high res videogame or simulation, I won't be scared, in fact I don't care.

will we ever get past the use of metaphor to explain everything?

N-connection *uniform* graph topology (brute force) search, just to speed things up?

Random topology modeled by the standard quantum gravity (e.g. fractional dimensions on the Planck scale) seems very unlikely. After all, it's not like this universe is some kind of 3D multiprocessor with faulty connections. That analogy would be going way too far.

Anyway, start with the 3-connection topology, then the 4-connection one, and so on, until you find the lowest N for which the model produces experimentally verified results.

My bet is still on N=12.

Ha, I wrote a story a while ago in which the universe, i.e. everything, is made up of building blocks I named vixels, living pixels. This was what allowed teleportation, time travel and replicators, each vixel has different sections, one has what it is, another everything it was and can be depending on specific agents (heat cold, time, etc.), another its location in space and time and another blank for introducing data to change any of the others. Once we discovered this, the rest was easy. Only thing is I called it Science FICTION.

The space may be made up of indivisible building blocks. I approached the space-time manifold begin with any lattice, regular or randon, composed of a simplicial triangulations, 4-simplex.

In accordance with Flipping Theory: "Flippon is the elementary particle and basic building block of the universe from which was produced all other particles by own breakage."
