GPS satellites have a little-known ‘Millennium Bug’ problem of their own


Do you remember the panic surrounding the Millenium Bug? Computer programs, built when storage space was at a premium, would often represent years as two digits. 1998 would appear as 98, and so on. When the millennium arrived, these two-digit years would roll over to 00, with some programs interpreting this as 1900.

This is the kind of news that makes me want to jump up and do a happy dance. These scientists may have produced an entirely new phase of matter. I’m going to do my best to explain what that means and why I personally believe this is the most important scientific breakthrough in our lifetimes. However, for the sake of clarity, there’s two points I need to make first: Time crystals are a… This story continues at The Next Web Or just read more coverage about: Google from The Next Web https://ift.tt/3fdRQlg
