Singularities panel, Transmediale (5th Feb 2017)The video of our #Singularities panel at Transmediale is now online:Featuring the extraordinary talents of Luiza Prado & Pedro Oliveira (A parede), Rasheedah Phillips, and Dorothy R. Santos speaking (and performing) on refiguring techno-colonialist and heteronormative pasts, presents, futures and identities.The introduction to the panel - written by Morehshin and myself - can be found here.

Why does our universe look the way it does? In particular, why do we only experience three spatial dimensions in our universe, when superstring theory, for instance, claims that there are ten dimensions -- nine spatial dimensions and a tenth dimension of time?

Japanese scientists think they may have an explanation for how a three-dimensional universe emerged from the original nine dimensions of space. They describe their new supercomputer calculations simulating the birth of our universe in a forthcoming paper in Physical Review Letters.

Before we delve into the mind-bending specifics, it's helpful to have a bit of background.

The Physics of Nothing; The Philosophy of Everything

SYNAESTHESIA is a neurological condition in which there is a merging of the senses, so that activity in one sensory modality elicits sensations in another. Although first described by Francis Galton in the 1880s, little was known about this condition until recently. A rennaissance in synaesthesia research began about a decade ago; since then, three previously unrecognized forms of the condition have been described, and hypotheses for how it arises have been put forward.

Two new studies now provide some insight into time-space synaesthesia, the least researched of all the forms of this fascinating condition. One is a case study of an individual whose time-space synaesthesia has an apparently unique characteristic. The second demonstrates that time-space synaesthetes are superior to non-synaesthetes in some cognitive abilities, and suggests that time-space synaesthesia may underly the savant-like abilities of people with hyperthymestic (or "super-memory") syndrome.

Dr. Nielsen and Dr. Ninomiya have proposed a kind of test: that CERN engage in a game of chance, a “card-drawing” exercise using perhaps a random-number generator, in order to discern bad luck from the future. If the outcome was sufficiently unlikely, say drawing the one spade in a deck with 100 million hearts, the machine would either not run at all, or only at low energies unlikely to find the Higgs.

Sure, it’s crazy, and CERN should not and is not about to mortgage its investment to a coin toss. The theory was greeted on some blogs with comparisons to Harry Potter. But craziness has a fine history in a physics that talks routinely about cats being dead and alive at the same time and about anti-gravity puffing out the universe.

As Niels Bohr, Dr. Nielsen’s late countryman and one of the founders of quantum theory, once told a colleague: “We are all agreed that your theory is crazy. The question that divides us is whether it is crazy enough to have a chance of being correct.”

We don't have any trouble coping with three dimensions – or four at a pinch. The 3D world of solid objects and limitless space is something we accept with scarcely a second thought. Time, the fourth dimension, gets a little trickier. But it's when we start to explore worlds that embody more – or indeed fewer – dimensions that things get really tough.

These exotic worlds might be daunting, but they matter. String theory, our best guess yet at a theory of everything, doesn't seem to work with fewer than 10 dimensions. Some strange and useful properties of solids, such as superconductivity, are best explained using theories in two, one or even no dimensions at all.

Prepare your mind for boggling as we explore the how, why and where of dimensions.
