This physicist is hunting for the biggest black hole in the universe

Astronomers have recently started looking for black holes bigger than galaxies. Brian Lacki explains how these 鈥渟tupendously large black holes鈥� might be used by alien civilisations, and what makes them such an intriguing possibility

Fractal conceptual illustration of supersymmetry or superstrings. Supersymmetry (SUSY) is a particle physics theory that proposes a type of spacetime symmetry relating two basic classes of elementary particles: bosons, which have an integer-valued 'spin', and fermions, which have a half-integer spin. If supersymmetry is a true symmetry of nature, it would explain many mysterious features of particle physics and would help solve paradoxes such as the cosmological constant problem. There is only indirect evidence for the existence of supersymmetry, primarily in the form of evidence for gauge coupling unification. Direct confirmation would entail production of superpartners at collider experiments, such as at the Large Hadron Collider.
