Tying Theory To Practice When Searching For Dark Energy

Science is a story of coming up with theories then doing our best to disprove them. That is especially true for theories on a grand, cosmological scale, though disproving them can be particularly hard. One of the most famous examples of a hard to disprove theory is that of dark energy and dark matter. In large parts of space we see unequivocal evidence that something is messing with general relativity. But down at the scale of our own solar system, there’s no evidence of it whatsoever, at least as far as we can see. A new paper from Slava Turyshev, a physicist at NASA’s Jet Propulsion Laboratory, discusses a way scientists might be able to deal with this discrepancy - by being very, very selective with the way we test for evidence of dark matter and energy in our solar system.
