For your first question, think about what your eyes are actually doing. They are recording light hitting them. The image is forming in your eyes.

Wind resistance seems to be the answer. If you present more of an area to the moving air then you will be subject to more drag, this has the effect of pushing you down.

I remember that experiment being performed at an open day quite a few years back when I was applying to universities. They certainly didn't claim it was producing energy from nowhere :D.

Because you cannot look at things from the point of view of the photon (remember the inertial frame does not exist) then this question doesn't really make sense. The frequency of a photon is a quantum mechanical property that is related to it's energy. So photons have different frequencies...

No all the evidence is very tenuous. There are very many reasons to think it exists, but directly observing it is all but impossible.

\[ \int_1^\infty {\frac{{dx}}{{x^2 }}} = 1 \] Just in case you were wondering.

You need psychiatric help.

How on Earth have you come to the conclusion that Quantum Electrodynamics is based on the double slit experiment?

Let d be the distance the particle falls. Let T be the time take for the ball to drop and the sound to reach the observer. Let t1 be the time taken for the particle to fall, and let t2 be the time taken for the sound to reach the top of the well. Also let v be the speed of sound. \[ T = t_1...

Whenever you look at expanding spacetime you have to use General Relativity. And it is a little known fact that in the General Theory spacetime can expand faster than light.

Sound is the change in pressure of a gas. A gas consists of particles with mass. They couldn't travel at the speed of light, but if they could travel close to it, they would have a very large energy. And the effect of a sound wave would be a bit like someone sandblasting your face.

Hi. It follows from Einstein's two postulates, that the speed of light is the same for all inertial observers, and that the laws of physics are the same in all inertial reference frames. The maths and all of special relativity comes from working through those postulates. But why it occurs...

All irrational numbers can be represented exactly by infinite series. Defining numbers without using numbers, now you are sounding like someone who has been puffing a bit too much on the old crack pipe.

We don't have an understanding of the mechanism behind inertia. A potential solution is the Higgs Field theory. Which hypothesises there is a higgs field with an associated higgs boson that gives objects their inertial mass. Basically a particle creates a disturbance in the higgs field and this...

Hi Yes 2.07x10^8m/s is correct. Remember that the frequency stays constant, so work out the original frequency using c = f* lamda, then insert that frequency into your second formula. Well total internal refraction occurs for all angles greater than the critical angle... does the light...
