The Compton wavelength of a particle is just the wavelength light would
have if the mass of the particle were converted to energy. As the
wavelength gets smaller the energy gets larger, at some point the energy
gets so high and the distance so small it turns into a Black Hole; that
distance is the Planck length the time it takes light to move that distance
is the Planck Time and the amount of mass required is the Planck Mass which
is about the mass of a flea egg. The most acceleration anything can have is
the Planck Acceleration, it is the amount of acceleration needed to move
something from a speed of zero to the speed of light in the Planck Time,
and the hottest that things can get is the Planck Temperature (1.4*10^32
Kelvin) because anything hotter would start radiating Black Holes instead
of Blackbody Radiation. Or at least that's what Quantum Mechanics says, but
if the evidence from the Fermi and Integral spacecraft holds up and
spacetime really is smooth then something is wrong with this picture.
