Artificial Solar System Could Search for Extra Dimensions
'The concept of extra dimensions, that there are whole other regions of reality that we can't perceive, has tantalized physicists for years. Although the math looks good (if you like that kind of thing), scientists want physical evidence they can measure.
And how do you test for 4 dimensions of space when you've only got a 3-dimensional ruler? One idea is to use gravity, a force that might actually reach across an extra dimension and give scientists the evidence they're looking for. In order to run this experiment, a pair of physicists think the best strategy is to start from scratch and build a whole new solar system... in miniature.'
