chefranden Posted June 27, 2008 Share Posted June 27, 2008 Using Causality to Solve the Puzzle of Quantum Spacetime * Quantum theory and Einstein’s general theory of relativity are famously at loggerheads. Physicists have long tried to reconcile them in a theory of quantum gravity—with only limited success. * A new approach introduces no exotic components but rather provides a novel way to apply existing laws to individual motes of spacetime. The motes fall into place of their own accord, like molecules in a crystal. * This approach shows how four-dimensional spacetime as we know it can emerge dynamically from more basic ingredients. It also suggests that spacetime shades from a smooth arena to a funky fractal on small scales. Read More... Link to comment Share on other sites More sharing options...
Sexton Blake Posted July 9, 2008 Share Posted July 9, 2008 I tend to think of gravity in a more simplistic term, that everything has fourth (physical) dimensional components and gravity (and inertia) is our footprint in that dimension. A bit like the ball on a sheet illustration except that it uses the centre of gravity rather than resting on a sheet. Link to comment Share on other sites More sharing options...
