Uncertainty principle http://en.wikipedia.org/wiki/Uncertainty_principle "In quantum mechanics, the Heisenberg uncertainty principle states by precise inequalities that certain pairs of physical properties, like position and momentum, cannot simultaneously be known to arbitrary precision. That is, the more precisely one property is measured, the less precisely the other can be measured. In other words, the more you know the position of a particle, the less you can know about its velocity, and the more you know about the velocity of a particle, the less you can know about its instantaneous position".

So, in the case of knowing extremely little about the velocity of a particle, how can you be sure it is below c ? Uwe Hayek. -- We are fast approaching the stage of the ultimate inversion : the stage where the government is free to do anything it pleases, while the citizens may act only by permission; which is the stage of the darkest periods of human history. -- Ayn Rand I predict future happiness for Americans if they can prevent the government from wasting the labors of the people under the pretense of taking care of them. -- Thomas Jefferson. Socialism is a philosophy of failure, the creed of ignorance, and the gospel of envy, its inherent virtue is the equal sharing of misery. -- Winston Churchill.

Suppose we have a balloon, filled with hot gas, but the balloon does not have a skin, its a hypothetical balloon. Suppose we push it through a hole that is just the size of the balloon. We measure the speed of the mass that passes through. The gas atoms are moving back and forth but this averages out, and we manage to measure the speed of the balloon. Now we push it through a very narrow hole, this squeezes the balloon in the middle. Now we try to measure the speed in this very narrow hole, but it is so narrow that only an atom at a time can pass. Each time we measure speed, it triggers on an atom flying back an forth at high temperature gas speeds. It is only an analogy, so do not deform it because you are not a lawyer. But maybe the analogy would work better if we have only one atom in the balloon. Then the balloon represents the uncertainty region.

Suppose we have a balloon, filled with hot gas, that we will call the sun, but the balloon does not have a skin, its a hypothetical balloon.
