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

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

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

In many ways, string theory attempts to go beyond Einstein's dream... an all-encompassing description of nature that works at large distances where gravity becomes…

— Ashoke Sen

“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

String theory envisions a multiverse in which our universe is one slice of bread in a big cosmic loaf. The other slices would be…

“Branes also opened up a whole new way of thinking about how our three-dimensional world might relate to the extra spatial dimensions of string…

— Lee Smolin

“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

I'd say many features of string theory don't mesh with what we observe in everyday life.

— Brian Greene

The most important single thing about string theory is that it's a highly mathematical theory, and the mathematics holds together in a very tight…

— Leonard Susskind

“On the other hand, if string theorists are wrong, they can't be just a little wrong. If the new dimensions and symmetries do not…
