Today’s word list-2 for The Hindu Editorial (Seeing darkness) – Apr 13, 2019:

black hole (noun) – a place in space where gravity pulls so much that even light can not get out. An extremely dense object from which no light can escape. Anything that comes within a black hole’s “event horizon,” its point of no return, will be consumed, never to re-emerge, because of the black hole’s unimaginably strong gravity.
collaboration (noun) – cooperation, alliance, partnership/association.
event horizon (EH) (noun) – an event horizon (EH) is a region in spacetime beyond which events cannot affect an outside observer. In layman’s terms, it is defined as the shell of “points of no return”, i.e., the boundary at which the gravitational pull of a massive object becomes so great as to make escape impossible.
envelop (verb) – cover, encompass, surround.
transgress (verb) – go beyond the limits of something; err/lapse.
photon (noun) – light quantum; the fundamental/elementary particle of visible light.
orbit (verb) – travel round, circle round, revolve round.
silhouette (noun) – a dark outline, contour, shape/form on the bright background (seen against a (bright) light).

postulate (verb) – put forward, theorize, speculate.
space-time (noun) – Time and space, according to Einstein’s theories of relativity, are woven together, forming a four-dimensional fabric called “space-time” (Courtesy: NASA).
supermassive black hole (noun) – the largest type of black hole, containing a mass of the order of hundreds of thousands, to billions of times, the mass of the Sun.
milky way (proper noun) – the galaxy (star system) that contains our Solar System.
interferometry technique (noun) – a family of techniques in which waves, usually electromagnetic waves, are superimposed, causing the phenomenon of interference, which is used to extract information
cutting-edge (adjective) – state-of-the-art, innovational, pioneering, revolutionary.
algorithm (noun) – calculation methods & processes.
