But to map out a
hypervelocity star's orbit within the dark matter halo, she first needs to know that star's motion through space.
To date, roughly 20
hypervelocity stars have been observed, mostly in the northern hemisphere, although it's possible that there are many more that can only be observed in the southern hemisphere.

hypervelocity weapons, particle beam weapons, and
The budget invests in improvements that complicate enemy targeting, harden our bases, and leverage gun-based point defense capabilities--from upgrading the Land-Based Phalanx Weapons System, to developing
hypervelocity smart projectiles that as I mentioned earlier can be fired not only from the five-inch guns at the front of every Navy destroyer, but also the hundreds of Army M109 Paladin self-propelled howitzers.

Hypervelocity Impact of Projectile with Thin Plate', Harbin Institute of Technology, 2010.
In 1968, Kornegay proposed a transmission resonant cavity technique, which was used to measure electron line density and collision frequencies in the ionized wakes of
hypervelocity projectiles [14].
22s that with shoot these latter two
hypervelocity rounds well.
Interferometric optical velocimetry is a primary diagnostic method for shock physics, pulsed power, and
hypervelocity experiments, and is used to measure a velocity time history for a surface of interest.
Critical velocity for rails in
hypervelocity launchers, Impact Engineering 33(1-12): 485-495.
The damage from such a
hypervelocity impact has been widely studied through tests and numerical simulations.
Its failure probability due to
hypervelocity impacts, and the probability of collision with identified conjuncting space objects have also been estimated.
We have seen reports that this pistol doesn't care for high or
hypervelocity.
