And this piece of equiptment only cost a hundred dollars or so, the idea that the OPERA people with their massive budget tried to do the same thing but were off by more than
60 feet is very hard to believe, and the idea that despite checking and rechecking the experiment for 10 months looking for errors some of the smartest people on the planet forgot to consider General Relativity is even harder to believe than that faster than light particles exist.</td>

things a lot - which tends to mean that experience with the practicalities of doing<br>those things is not gained, which - combined with the natural tunnel vision of those<br>who analyze only those narrow subfields the equipment is intended for - leads to<br>
errors like this.<br></div></div><br>
