PSA: Watch the AMS dark matter results announcement at 1:30PM ET (video)

The universe is thought to be composed of stuff, non-stuff and maybe some other stuff. We're referring, of course, to matter, anti-matter and as-yet illusive dark matter. While we know a fair amount about matter and its opposite, dark matter is still largely theoretical. That might change in around half an hour, though, as folks from NASA, MIT and the US Department of Energy hold a press conference to explain exactly what the Alpha Magnetic Spectrometer (AMS) strapped to the ISS has been seeing during almost two years of space-scanning. Samuel Ting from MIT, who will be on the panel, implied back in February that today's results will provide the first evidence of dark matter's existence -- if that's the right term. The press conference is due to start at 1:30PM EDT, so make sure to tune in to the NASA TV livestream embedded below for what could be the biggest scientific news since Higgs and his boson.
