Some celestial bodies are so cold that methane freezes; others are so hot that nuclear reactions occur. And then there’s Earth, with a benign temperature hovering in the narrow range between freezing ...

In string theory, a paradigm shift could be imminent. In June, a team of string theorists published a conjecture which sounded revolutionary: String theory is said to be fundamentally incompatible ...

Physicists have proposed a new model of space-time based on string theory to explain dark energy. Their hypothesis suggests that, at extremely small scales, space and time behave differently from how ...
