I didn't watch the entire video, so SH may have mentioned, but there has long been a theoretical particle called a tachyon which can (could!) move faster than light because it is created already moving at that speed (if it existed).

- mr_mitm 4y agoThere is zero reason to believe that tachyons exist. It's just a name we gave to a concept. Dark matter doesn't have to exist either purely because we decided to give an idea this name. (But there are other reasons to believe that dark matter exists, namely observations.)
