Why can muons in the atmosphere travel 10 km if their predicted life should only allow them to travel 600 m (pg. 70)?
They travel at nearly the speed of light so they create wormholes
They weigh virtually nothing so travelling burns virtually no calories
They cheat
They travel near light speed so time is 7 times slower for them

Yes
15
Which of the following statements about translation is incorrect?
