We have never seen them directly,yet we know they
are,lurking within dense star clusters
or wandering the dust lanes of the galaxy,where they prey on stars or eat
planets whole.Our milky way may harbour millions of black holes,the ultra dense
remmants of dead stars.But now,in the universe far outside our galaxy,there’s clue
of something far more apocalypic,A breed of black holes that has reached
incomprehensible size and destructive capacity.Just how large,and violent,and
strange can the get? A new era in astronomy has revealed a universe long invisible
to us.High-tech instruments sent into space have been to sense high-energy
forms of light.x-ray and gamma rays-that are invisible to our eyes and don’t
penetrate our atmosphere.On the field precision
telescopes are equipped with technologies that allow them to cancel out the
blurring effects of the sky . They are peering into the far reaches of the
universe,and into distant caldrons of light and enrgy.In some distant
galaxies,astronomers are now finding evidence that space and time are being
shattered by eruptions so vast they boggle the head .We are just beginning to
understand the impact these outbursts have had on the universe: on the shapes
of galasxies,the spread of elements that make up stars and planets ,and
ultimately the very existence of Earth.
