Why is c the speed limit?

Is it because the mass of a particle and its waviness increases as it
approaches c?

....

How would you define a tachyon, and what are its properties?

http://scienceworld.wolfram.com/physics/Tachyon.html

It's kind of like c is 1, and massy particle obeying Newton's inertia
law speed is infinitesimal, and tachyon speed infinite, and particle
and tachyon speed are reciprocal.

Yeah. It's kinda like that. :-)


Why is that so?

The tachyon is a theoretical lack of particle- and wave-ness that
travels, in a way, at a speed that is basically from c on out to
infinity.

The speed of light, c, reminds of the Planck length, scripty h, and
scripty h slash, the Planck length divided by 2pi. Then there's the
fine structure constant and stuff.

There is a lot of utility in the application of the mathematics of
geometric algebras with discussing the space-, time-, and light-like
"vectors", with the 3-1 or 3-2 projections. How many bases does light
get?

A travelling photon has a frequency. It's generally among zillions of
other photons flowing in all directions from the omnidirectional
source, in a cone from the cone light source, or in a single line from
the unidirectional point source. The massy, charged, stream of
photons floods through the cornea and fluids of the eyeball to the
sensitive photorecepting rods and cones of the eye, there converted to
electrical signals, carried by chemical messengers from endpoint to
endpoint of the neurons of the thick cable of the optic nerve directly
into the visual cortex, a clump of a biological network (neural
network) that is interpreted when visual from the upside-down image
focussed on the retina to what is then interpreted by the brain as a
continuously variable image, because natural light is not coherent.

The photon, with charge measured in "electron Volts", eV's, has about
the same charge as an electron, a difficult kind of subatomic
particle.

The standard model of physics has the elements being those masses of
atoms with equal atomic numbers, the atomic number is the number of
"protons", or comparatively massy to the "negative" "orbiting"
electrons composites of, here I got lost, something about "hadrons" or
"muons" or "leptons", quarks and quarks of the standard model, which
follow some proportional constants of multiples of three in
diminishing "mass".

At some point in time the mass diminishes so much that the sum
energy/mass of the "particle" demands that its "frequency" rise where
the mass and energy present in that "continuous" section of the
coordinate space equate to represent the charged, oscillating,
inertial potential or actuality of the "non-empty space."

So as the mass goes to zero, of the particle with mass and oscillating
frequency, the frequency goes to infinity, with fixed energy. As the
particle goes to c, mass goes to infinity.

What is "local frequency adjustment zone."

The "neutron" is often found within the "nucleus" of the atom, in some
respects the neutron is a proton infinitely compacted with an
electron, but the mass and "charge" of the proton and electron don't
_sum_ to exactly that of the neutron. In some forms of "radioactive
decay" the neutron decomposes to an electron and proton pair, changing
the atom from being one element to another, in increasing the atomic
number, but not atomic mass, of the atom.

Within the standard model there are various considerations of gravity,
strong and weak, and other forces that act upon the mass/energy that
fill the infinite three-dimensional space that characterizes the
observable universe.

I guess I don't yet understand why there are any boundaries like the
Planck length, or rather, what physical effect occurs at those
boundaries. Can not light vary continuously in frequency from one to
the next?
