In physics, a shock wave (also spelled shockwave), or shock, is a type of propagating disturbance that moves faster than the local speed of sound in the medium. Like an ordinary wave, a shock wave carries energy and can propagate through a medium, but is characterized by an abrupt, nearly discontinuous, change in pressure , temperature , and ...
Such shocks are formed by photons colliding with the electrons of the matter, and the downstream of these shocks is dominated by radiation energy density rather than thermal energy of matter. An important type of astrophysical shock is the relativistic shock, in which the shock velocity is a non-negligible fraction of the speed of light.
Megatron would also appear in the Energon promotional comic. On Earth, Megatron, with the aid of Snowcat, Shockwave, Mirage and Demolishor, has cornered Optimus Prime and a wounded Hot Shot. Optimus refused to give up despite the odds. The other Autobot reinforcements were over ten minutes away when Wing Saber arrived. Megatron was shocked to ...
The bright flash of the shockwave, or as astronomers call it the "shock breakout," pushes outward as the distant body turns from star to supernova.
For Earth and other magnetized planets, it is the boundary at which the speed of the stellar wind abruptly drops as a result of its approach to the magnetopause. For stars, this boundary is typically the edge of the astrosphere , where the stellar wind meets the interstellar medium .
The first hypernova observed was SN 1998bw, with a luminosity 100 times higher than a standard Type Ib. [9] This supernova was the first to be associated with a gamma-ray burst (GRB) and it produced a shockwave containing an order of magnitude more energy than a normal supernova.
Starscream helps Shockwave clone two Predacons, Skylynx and Darksteel, as part of their plan to rebuild the Decepticon army, and is later witness with Shockwave to the arrival of Unicron (possessing Megatron's upgraded and resurrected body), who plans to destroy his brother Primus, who forms Cybertron's core.
