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.
