Relativistic rocket means any spacecraft that travels close enough to light speed for relativistic effects to become significant. The meaning of "significant" is a matter of context, but often a threshold velocity of 30% to 50% of the speed of light (0.3 c to 0.5 c ) is used.
The Lorentz self-force derived for non-relativistic velocity approximation , is given in SI units by: = ˙ = ˙ = ˙ or in Gaussian units by = ˙. where is the force, ˙ is the derivative of acceleration, or the third derivative of displacement, also called jerk, μ 0 is the magnetic constant, ε 0 is the electric constant, c is the speed of light in free space, and q is the electric charge of ...
The total energy of these electrons is estimated at 5.1 × 10 56 ergs [97] (5.1 × 10 49 joules or 3.2 × 10 68 eV). This is roughly 10 13 times the energy produced in the entire Milky Way in one second, which is estimated at 5 × 10 36 joules. [98] The jet is surrounded by a lower-velocity non-relativistic component.
It is the non-relativistic limit of the Dirac equation and can be used where particles are moving at speeds much less than the speed of light, so that relativistic effects can be neglected. It was formulated by Wolfgang Pauli in 1927. [1] In its linearized form it is known as Lévy-Leblond equation.

In the second edition, the corresponding sections were scrapped and replaced with more topics in the well-established quantum electrodynamics, and the two parts were unified into one, thus providing a one-volume exposition on relativistic quantum field theory with the electromagnetic interaction as the prototype of a quantum field theory.
This relation can be thought to represent the non-relativistic decomposition of the electromagnetic 4-vector potential. Indeed, a system of point-particle charges moving slowly with respect to the speed of light may be studied in an expansion in v 2 / c 2 {\displaystyle v^{2}/c^{2}} , where v {\displaystyle v} is a typical velocity and c ...
Hans Albrecht Bethe (/ ˈ b ɛ θ ə /; German: [ˈhans ˈbeːtə] ⓘ; July 2, 1906 – March 6, 2005) was a German-American physicist who made major contributions to nuclear physics, astrophysics, quantum electrodynamics and solid-state physics, and received the Nobel Prize in Physics in 1967 for his work on the theory of stellar nucleosynthesis.
