The unit of energy in the system of Planck units.
EP = √ (ħ c5/G) ≅ 1.22 x 1019 GeV.
It can also be defined as
EP = ħ / tP, where tP
is the Planck time. This is an extraordinarily large amount of
energy on the subatomic scale and particle accelerators have yet to
produce a particle with this magnitude of energy.
Understanding the properties of a subatomic particle that contains the Planck Energy is
helpful in developing a Unified Field Theory which encompasses the
realms of Quantum Theory and Relativity, although this too has evaded
complete scientific understanding.
