Precisely Fast

      Okay so accuracy is if you get the actual measurement, and precision is where the same results would be reproduced. [To make this measurement, scientists used very precise differential GPS, and their measurement was so precise, they could track continental drift between the two locations, and a 2009 earthquake that produced a 7cm shift in the earth’s crust shows up as clear as day.]* They used precise instruments so they were able to get the same result multiple times to come to one conclusion. As far as significant digits go they can be very important when working with the right numbers.
[ But that’s basically the value for the speed of light, so what’s the big deal? The sig fig police would tell you that number is impossible to distinguish from , the defined value for c.
     Good thing the scientists who did this work weren’t nearly so lackdaisical with their measurements as the journalists were in reporting them
.]* Like he said they could look like the same thing but in reality they are a bit different, considering that I am not a physicist yet i couldn't tell you the difference. As far as super fast neutrinos that's pretty crazy, it kinda throws off what the Theory of General Relativity states that nothing is faster than the speed of light. This could lead to many different discoveries, like possibly piecing together the big bang.
