What does it mean if the universe has extra dimensions?

Comment

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.

The first quantum fluctuations set into motion a huge cosmic mystery

The earliest acoustic vibrations in the cosmos weren’t exactly sound – they travelled at half the speed of light and there was nobody around to hear them anyway. But Jim Baggott says from the first moments, the universe was singing
