Usage examples of "high-energy".
We cannot use this approximation when dealing with short-distance or high-energy processes because we know that the extended nature of the string is crucial to its ability to resolve the conflicts between general relativity and quantum mechanics that a point-particle theory cannot.
When a burster spat out its virulent, high-energy emissions, a network of telescopes went into operation, recording its brief life.
Releasing high-energy particles into the regions near the many thousands of communications satellites would destroy them by charging them up until the potentials shorted out components.
No high-energy weapons, unfortunately -- these are jealously monopolized by the saurs and stashed in the skiffs or on ships.
As a result, the color index she had created to display the wormhole's bursts of high-energy radiation on the main viewscreen kept shifting from an angry bruiselike red-violet to an icy borealis shimmer of translucent blue to a deep electric indigo sparked with hot white highlights.
They strapped each man into a huge human milkshake apparatus that vibrated the body at tremendous amplitudes and bombarded it with high-energy sound, some of it at excruciating frequencies.
Within this region, space and time recoupled and contracted inward with the imploding core to simulate for an instant the bizarre, inverted conditions of an antiuniverse, and in that instant a large portion of the tweedles liberated in the process transformed into antitweedles which, under the prevailing high-energy conditions, combined preferentially into antiquarks and antileptons rather than radiation.
A Bussard ramjet will put out a lot of funny chemicals: high-energy hydrogen and helium, lithium radicals, some borates, even lithium hydride, which is generally an impossible chemical.

A four-foot-diameter beam of high-energy laser light shot from the nose of the AL-52 and was focused by the deformable mirror down to a spot the size of a basketball on the motor section of the first rocket.
The suit could protect him against alpha and beta particles, but any gamma radiation in the vicinity-induced, say, by high-energy neutrons irradiating this enormous mass of twisted, heat-blackened metal before him-would be sleeting right through his suits slender defenses.

But now there were spreading pools of white light at the rims of the magmatic convection cells: plasma, presumably, from the high-energy stuff going on in the interior.
The high-energy cosmic rays barrel into it and create ionized atoms.
We have evidence from cosmic rays that the same is true for all the matter in our galaxy: there are no antiprotons or antineutrons apart from a small number that are produced as particle/ antiparticle pairs in high-energy collisions.
