The world is all set to see the first picture of a black hole.
On Wednesday, astronomers across the globe will hold “six major press conferences” simultaneously to announce the first results of the Event Horizon Telescope (EHT), which was designed precisely for that purpose.
It has been a long wait.
Of all the forces or objects in the Universe that we cannot see including dark energy and dark matter none has frustrated human curiosity so much as the invisible maws that shred and swallow stars like so many specks of dust.
Astronomers began speculating about these omnivorous “dark stars” in the 1700s, and since then indirect evidence has slowly accumulated.
“More than 50 years ago, scientists saw that there was something very bright at the centre of our galaxy,” Paul McNamara, an astrophysicist at the European Space Agency and an expert on black holes, told AFP.
“It has a gravitational pull strong enough to make stars orbit around it very quickly as fast as 20 years.”
To put that in perspective, our Solar System takes about 230 million years to circle the centre of the Milky Way.
