eldavojohn writes: Petr Horava, a physicist at the University of California in Berkeley, has a new theory about gravity and spacetime. A high energies, it actually snips any ties between space and time (as opposed to the Theory of General Relativity at low energies that binds them together). It is picking up steam and gaining popularity with physicists because it fits a lot of observed models better than Einstein's or Newtonian solutions. It better predicts the movement of the planets and has a potential to create the illusion of dark matter--something we've been trying to decipher for a long time.
I've never been canoeing before, but I imagine there must be just a few
simple heuristics you have to remember...
Yes, don't fall out, and don't hit rocks.
