... the source. It is these ‘ripples’ of space-time that are detected as gravitational waves. These waves travel at the speed of light carrying information about their progenitor and they can also be produced by other violent events in the cosmos...
... fast moving material has been spotted racing around near its event horizon at about 30 percent the speed of light; this is the most detailed observations yet of material swirling around so close to a black hole at the point of no return...

...area, illuminated by a high power laser (around 60 GW) to accelerate a 1 gram-scale spacecraft to a significant percentage of the speed of light as a means of sending multiple robotic probes to nearby stars in decades, not millennia. While just about...

... the ergosphere, magnetic reconnection is so extreme that the plasma particles are accelerated to velocities approaching the speed of light, added Comisso. The high relative velocity between captured and escaping plasma streams is what allows the...
