String theory predicts ten total spacetime dimensions, but we clearly live in a world with four dimensions (three space and one time)! Thankfully, it is not a problem to get from ten to four.

String theorists are shifting ... a conformal field theory is just a certain special case of scale invariant field theory, but almost all the time when physicists say “conformal”, they really ...

In order for the math to work, string theory requires that there be 10 dimensions: nine of space and one of time. Our universe only appears to have three spatial dimensions, string theorists say ...

Was the big bang really the beginning of time? or did the ... implications of string theory. Third, quantum strings demand the existence of extra dimensions of space, in addition to the usual ...

which can be visualised with elastic bands that move in space-time. The fifth theory has open strings, which can be visualised with elastic bands cut open. In string theory the physics is limited ...

String theory is certainly beautiful in the eyes of many physicists. Beautiful enough to pursue even if it’s wrong? PBS Space Time is available to stream on pbs.org and the free PBS App ...

LEGIONS of disembodied brains floating in deep space threaten to undermine ... deny Boltzmann brains the infinite time they need to outnumber us. String theory might be able to help, says Zukowski ...

Space and time, Wüthrich says, could work the same way in string theory and other theories of quantum gravity. Specifically, spacetime might emerge from the materials we usually think of as livin ...

Voila, string theory is saved. Modern M theory proposes an additional large spatial dimension. Our universe of 3D space and 1-D time is like flatland on this 5D object called a 5-brane.
