Evolution: Careful with that amphioxus

  author={Henry Gee},
923 the brane in the extra dimensions of the purely gravitational theory. Variations in quark coupling turn up as a variation in a gravity field in this radial direction. Crucially, gravity fields are weakly coupled and therefore easy to compute — unlike the fields of QCD. Another consequence of the strong coupling in QCD is that its vacuum is actually filled with quark–antiquark pairs, created by ‘borrowing’ energy for a short period of time, as permitted by the Heisenberg uncertainty… CONTINUE READING
