Planck scale


Planck's scale - the scale of energy in the vicinity 1 , 22 ⋅ 10 19 {\displaystyle 1,22\cdot 10^{19}} GeV (corresponding to Planck mass) at which the quantum effects of gravity become strong. In this scale, the description of the interaction of subatomic particles in the quantum field theory is broken down (due to the non-normalized gravity). Although physicists have quite a good understanding of other fundamental effects at the quantum level, gravity is problematic and can not be integrated into quantum mechanics (in high energies) using quantum field theory. With energies moving to Planck's scale, accurate quantum gravity theory is needed; The leading candidate is string theory, or its modification - M-theory. Other approaches to the problem include loop quantum gravity, causal dynamic triangulation, and non-floating geometry. Planck's gravity is estimated to be comparable to other forces and is likely to unify all fundamental influences, but details of this unification remain unknown. Similarly - the term Planck's scale is related to the length scale in the vicinity 1 , 616 ⋅ 10 & # x2212; 35 {\displaystyle 1,616\cdot 10^{-35}} subway, or Planck length (which is associated with Planck's energy through the uncertainty principle). In this scale, concepts of size and distance collapse. Because the Compton wavelength is close to the Schwarzschild black hole in the Planck scale, a photon of sufficient energy to investigate this sphere would give no information. Any photon of sufficient energy to measure an object on this scale could create a particle of that size that would be massive enough to immediately become a black hole, completely distorting the region of the space and swallowing a photon. This most extreme example of the principle of uncertainty explains why only quantum gravity theory which unifies general relativity and quantum mechanics will understand the dynamics of space-time on this scale. It is important in cosmology, because if you trace the evolution of the cosmos back to the very beginning, at a very early stage, the universe should be so hot that processes involving Planck's energy order (corresponding to Planck's longitudinal range) could be carried out. For this reason, this period is called the Planck era.
