He did so in 1930, when he was a graduate student travelling by ship from his home in India to study at the University of Cambridge, UK. Even before he got to Cambridge, Chandrasekhar knew more about relativity and quantum mechanics than most of his teachers. He knew how to take account of both when building mathematical models of cold stars that had stopped shining. On board the ship, once he he had finished his calculations, he came to a startling conclusion: he found that there exists a critical mass, now known as the Chandrasekhar limit, beyond which no cold star made of ordinary matter can exist.

From a careful analysis of the stratigraphy, That water once flowed on the surface textures and composition of the entire of Mars seems clear from decades of exposure. Remarkably, these investigations awe-inspiring spacecraft images of valley at Endurance were completed after about networks and giant fluid-carved channels. 320 sols, or martian days, four times longer Most of the valley networks are in the than the design lifetime of the rovers. The most ancient terrains, however, and were team concludes that the sandstones were possibly formed only by the melting of formed by the erosion and redeposition of ice by impacting debris left over from fine-grained silicate particles and evaporthe formation of the Solar System.

It involves extra dimensions galore: not just Einstein’s four, or the five that also incorporates electromagnetism, but a total of 10 or 11. The extra dimensions are viewed as very small and curled up, so that, for most purposes, we are not aware of them. They only manifest themselves at very high NATURE|Vol 438|22/29 December 2005 energies, of the kind encountered in particle accelerators. Moreover, these extra dimensions are constrained by very precise symmetry requirements. The upshot of this is that string theorists can exhibit plausible models of a unified Universe, but unfortunately they cannot explain why we inhabit a particular one.
