  • Many physicists had a heart attack when we got news from Geneva, Switzerland that Einstein

  • might be wrong. All hell broke loose in the physics community. Every physicist I know

  • was taking a position on this hot topic because relativity is the foundation of modern physics

  • along with the Quantum Theory.

  • Now what they found was if you take a beam of neutrinos from the atom smasher in Geneva,

  • Switzerland, shoot the beam through the mountains from Switzerland to Italy over a distance

  • of 454 miles, the neutrinos out-raced a light beam by a distance of 60 feet, 60 feet over

  • a distance of 454 miles. Well, that doesn't sound like much, but to a physicist this is

  • a disaster. It means that the foundations of modern physics have to be called into question.

  • First, it means that time travel could become commonplace because as you approach the speed

  • of light time slows down. If you exceed the speed of light, time goes backwards. Remember

  • that scene in Superman One when Lois Lane dies and Superman goes into outer space and

  • goes around the planet earth in the opposite direction; the earth stops and then rotates

  • in the opposite direction and then, all of the sudden, Lois Lane springs back to life?

  • Well, that kind of scenario might be possible if the speed of light is not so special that

  • particles can exceed the speed of light, not to mention that we'll have to recalibrate

  • everything - the age of the universe, the age of stars, the distance to the stars, the

  • basic structure of modern electronics has to be changed, the GPS, nuclear weapons, all

  • of that would have to be recalibrated and rethought through if Einstein's theory of

  • relativity is wrong. So what's the solution to the problem? Well

  • the solution to the problem is obviously they goofed. They made a mistake. I remember when

  • I was a grad student years and years ago at Harvard. My advisor at Harvard was Professor

  • Pound and he the famous Pound-Rebka Experiment where they shot a light beam from the top

  • of Jefferson Hall to the bottom of Jefferson Hall. Now, there was a rival group, a rival

  • group that also did the same experiment and they had to calculate the speed of light in

  • the process. They found that the speed of light actually rose in the morning, peaked

  • at noontime. Then the speed of light began to slow down at dinnertime and reached a minimum

  • at midnight. Well, this was shocking. The speed of light, which governs the universe

  • all of the sudden is wedded to lunchtime and dinnertime. So what's the problem? The problem

  • was that this counter experiment, this rival experiment, was done outdoors, and the sensors

  • were temperature-dependent, and of course it's warmer at lunchtime and colder at midnight.

  • Well, Professor Pound's experiment was done indoors and therefore, didn't have that kind

  • of variation. The lesson here is: systematic errors creep

  • into very delicate calculations. Some people think they found the source of the error.

  • How do we know that from Switzerland to Italy the distance is 454 miles? Well, you use GPS,

  • right? Obvious, but GPS is a relativistic system. It uses relativity and some physicists

  • have claimed that they mis-calibrated the distance from the sensors to the satellite

  • and satellite back down to Italy, a triangle; that one of the lengths of the triangle was

  • mis-calibrated in the process of doing this experiment.

  • Now, there is another counter example. Back in 1987, light from a gigantic supernova in

  • the Magellanic Clouds hit the planet earth and, simultaneously with that, neutrinos were

  • detected in gigantic neutrino detectors in Japan. So we had a double whammy - light from

  • a supernova right near the Milky Way Galaxy hitting the earth at the same time as neutrinos

  • from a galaxy tens of thousands of light years from the earth.

  • So here's the rub. Why should we believe this CERN experiment over a distance of 454 miles

  • when over a distance of tens of thousands of light years neutrinos and light beams hit

  • the earth at the same time? That's why many physicists believe that they must have made

  • a systematic error someplace and the weak link, the weak link in this whole chain of

  • reasoning is the GPS system, and the GPS system itself is a relativistic system. So in some

  • sense they're using relativity to defeat relativity and I think there is something circular about

  • that.
