Being Quote by Edward Witten

As you say, the way string theory requires all these extra dimensions and this comes from certain consistency requirements about how string should behave…

— Roger Penrose

As of now, string theorists have no explanation of why there are three large dimensions as well as time, and the other dimensions are…

— Edward Witten

Technically you need the extra dimensions. At first people didn't like them too much, but they've got a big benefit, which is that the…

— Edward Witten

“I think string theory provides an explanation.” “Some think that it is only when two strings encounter each other and some qualities are canceled…

— Liu Cixin

String theory is not the only theory that can accommodate extra dimensions, but it certainly is the one that really demands and requires it.

— Brian Greene

One of the strangest features of string theory is that it requires more than the three spatial dimensions that we see directly in the…

— Brian Greene

“For string theory to make sense, the universe should have nine spacial dimensions and one time dimension, for a total of ten dimensions.”

— Brian Greene

“Extending Polyakov's argument, he found evidence that the string theory describing those emergent strings is actually a ten-dimensional supersymmetric string theory. Of the nine…

— Lee Smolin

String theories, for instance, they require seven additional dimensions. So, as experimentalists we should, with our high-tech instruments like the Large Hadron Collider, just…

— Fabiola Gianotti

You have that one basic string, but it can vibrate in many ways. But we're trying to get a lot of particles because experimental…

— Edward Witten

“Strings possess one defining property which is their tension. This quantity plays a crucial role in the overall picture of how strings can be…

— John D. Barrow

According to String Theory, what appears to be empty space is actually a tumultuous ocean of strings vibrating at the precise frequencies that create…
