Sentences with phrase «nearby matter»

They can be «observed,» however, by the effects of their enormous gravitational fields on nearby matter.

Astronomers previously thought that this type of «ultraluminous X-ray source» was likely to be made up of black holes five to 50 times more massive than our sun, radiating energy as they pull in nearby matter.

As detailed in this video, Laniakea's discovery emerged from measurements of galactic positions and velocities that reveal how galaxies are moving in relation to concentrations of nearby matter and the universe's overall expansion.

Dust from the collisions could explain why many of these colossal objects, which would otherwise shine brightly as they swallow nearby matter, are hidden from view.

Where they differ is that steady staters believe some objects with high redshifts — especially certain quasars — are actually nearby matter traveling at a high velocity.

As these beasts sucked in nearby matter, they cast off brilliant radiation at every wavelength from radio to gamma rays.

Quasars, discovered in 1963, are extremely distant massive black holes (MBHs) whose gravity pulls in immense amounts of nearby matter.24 The potential energy of all that infalling matter is converted to bright radiation, making quasars the most luminous stable objects in the universe.

Their idea was to mimic the properties of a cosmological black hole, whose intense gravity bends the surrounding space - time, causing any nearby matter or radiation to follow the warped space - time and spiral inwards.

But contrary to the big bang theory, that matter is enriched with heavy metals.25 Black holes that are not at extreme distances are nearer to us in time, so they have already pulled in all nearby matter.

At some «tipping point,» the process becomes pretty much unstoppable except by exhausting the nearby matter.
