What Is String Theory?

Podcast of the Day

Brian is a theoretical physicist with a knack for explaining mind bending things in everyday language.

His books cover the science of extremely big things, like the shape of time and space, and how gravity works as well as extremely small things like particle physics, the behavior of atoms.

He also explained that these two branches of science work really well on their own, but they don't mesh together, not yet.

But he thinks there is a theory that would resolve this conundrum, called string theory.

String theory suggests that everything in the universe is made up of impossibly tiny, quivering strings of energy.

Short Article of the Day

String theory entered the public arena in 1988 when a BBC radio series Desperately Seeking Superstrings was broadcast.

Thanks to good marketing and its inherently curious name and features, it’s now part of popular discourse, mentioned in TV’s Big Bang Theory, Woody Allen stories, and countless science documentaries.

But what is string theory and why does it find itself shrouded in controversy?...

Further Reading

In physics, string theory is a theoretical framework in which the point-like particles of particle physics are replaced by one-dimensional objects called strings. It describes how these strings propagate through space and interact with each other. On distance scales larger than the string scale, a string looks just like an ordinary particle, with its mass, charge, and other properties determined by the vibrational state of the string. In string theory, one of the many vibrational states of the string corresponds to the graviton, a quantum mechanical particle that carries gravitational force. Thus string theory is a theory of quantum gravity...
