IT WAS A RAINY NIGHT WHEN THE FUTURE became a place, one you could visit. A downpour at sunset couldn't, just couldn't discourage the 200,000 people who -

Who had gathered for the opening ceremony of the 1939 New York World Fair, ''World of Tomorrow ''  was the theme of this art deco land of promise.

There were television sets, calculating machines, and a robot. For the first time, people saw these things that would change their lives. But on that night they had come to hear the greatest scientific genius since Issac Newton.

Albert Einstein was to give brief remarks and flip the switch that would illuminate the fair. The spectacle promised to be the largest flash of artificial light in technical history, visible for a radius of 40 miles. A WOW - but not as mind blowing as the source of this  sudden, unprecedented brilliance.

Scientists would capture cosmic rays and and transmit them to Queens, where they would supply the energy that would turn night into day, flooding with blinding light a new world made possible by science.

2019-2020 and Scientists detect mysterious ''intermediate mass'' black hole. GW190521 weighs in at 142 times the mass of Sun.

SCIENTISTS ANNOUNCED WEDNESDAY the discovery of a back hole - the oldest ever detected -that shouldn't even exist according to the current understanding of cosmic monsters so dense not even light can escape their gravitational pull.

Born of a merger between two other black holes, GW190521 weighs in at 142 times the mass of our Sun and is the first ''intermediate mass'' black hole ever observed, two consortiums of some 1,500 scientists reported in a pair of studies.

''This event is a door opening into the cosmic process for the formation of black holes,'' co-author Stavros Katsanevas, an astrophysicist at the European Gravitational Observatory, said in an online press conference.

''It is a whole new world.''

A so-called stellar-class black hole forms when a dying star collapses, and is typically three to ten solar masses in size.

Supermassive black holes found at the centre of most galaxies, including the Milky Way, range from millions to billions of solar masses.

Up to now, black holes with mass 100 to 1,000 times that of our Sun had never been found. 

''This is first evidence of a black hole in this mass range,'' said co-author Michaela, an astrophysicist at the University of Padova, and a member of the Europe based Virgo Collaboration.

''It may lead to a paradigm shift in the astrophysics of black holes.''

The findings, she added, support the idea that supermassive black holes could be formed through the repeated merger of these mid-sized bodies.

What scientists actually observed  were gravitational waves produced more than seven billions years ago when GW 190521 was formed by the collision of two smaller black holes of 85 and 65 solar masses.

When they smashed together, eight solar masses worth of energy was released., creating one of the most powerful events in the Universe since the Big Bang.

Gravitational Waves were first measured in September 2015, earning the lead researchers a Physics Nobel two years later.

Albert Einstein anticipated gravitational waves in his general theory of relativity, which theorised that they spread through the Universe at the speed of Light.

GW190521 was detected on May 21, 2019 by three interferometers, which can measure a change thousands of times smaller than an atomic nucleus as gravitational waves pass Earth. [AFP]
