In the book, I make the point that here we have string…

The basic theory in twistor theory is not to add extra dimensions.

“Over the last three decades, theorists have proposed at least a dozen new approaches. Each approach is motivated by a compelling hypothesis, but none…

If we approach Nature with , it will serve us as our best friend, a friend that won't let us down.

— Mata Amritanandamayi

Reason must approach nature with the view, indeed, of receiving information from it, not, however, in the character of a pupil, who listens to…

Time travel and teleportation will have to wait. It may take centuries to master these technology. But within the coming decades, we will understand…

For bedtime reading, I usually curl up with a good monograph on quantum physics or string theory, my specialty. But since I was a…

The beauty of string theory is the metaphor kind of really comes very close to the reality. The strings of string theory are vibrating…

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

Every string theory that's been written down says the speed of light is universal. But other ideas about quantum gravity predict the speed of…

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…

The full name of string theory is really superstring theory. The 'super' stands for this feature called supersymmetry, which, without getting into any details,…
