String theory has its supporters and its gainsayers among theoretical physicists. Even advocates admit that the theory could be entirely wrong (though naturally they don't think it is).

One of the most striking consequences of this quantum space-time, as predicted by string theory, is that it naturally leads to cosmic acceleration. Moreover, the researchers found that the rate at ...

String theory is perhaps the most high-profile candidate for what physicists call a theory of everything – a single mathematical framework capable of describing the entirety of the known universe.
