This could be the way the world ends. First, a pair of cosmic protons smash together at unimaginable speeds. The tremendous energy of their crash would create a tiny, ephemeral black hole, so small ...

While last year’s discovery of gravitational waves from colliding neutron stars was Earth-shaking, it won’t add extra dimensions to our understanding of the universe—not literal ones, at least. The ...

What is string theory: It replaces point-like particles with tiny vibrating strings, requiring extra dimensions to reconcile ...
