Scientists Release First-Ever Image of Black Hole

Scientists Release First-Ever Image of Black Hole”

Black holes are areas in space where gravity is so strong that nothing - not even light - can escape them.

The first image ever seen of a black hole.

The existence of black holes was first predicted in 1916.

"Black holes are stranger than anything ever dreamt up by science fiction writers, but they are firmly matters of science fact". The scientists look for a ring of light - hot disrupted matter and radiation circling at tremendous speed at the edge of the event horizon - around a region of darkness representing the actual black hole. The shadow can be thought of as a magnified image of the event horizon, which is the point of no return for gas falling into the hole. Now, however, a global team of researchers has finally captured an image of a black hole, revealing the distant object in stunning detail.

The mission is a "high-risk but high-payoff endeavor", Doeleman said. "We saw something that really had a ring to it, if you can use that term or phrase".

"We've been at this so long that there's such a buildup", he said.

But the idea resurfaced in physics in 1916, when Albert Einstein revolutionized our understanding of the cosmos with his general theory of relativity. That's a simple difference to explain-initial evidence shows that we're viewing M87's black hole from closer to one of the poles, rather than from head on.

"Today general relativity passed another crucial test", said University of Waterloo astronomer Avery Broderick, a co-discoverer.

Einstein himself didn't initially notice the possibility for black holes in his equations. "So often in my experience, nature wants to be beautiful". He wasn't part of the discovery team. What you're actually looking at is the fact that M87's black hole is probably spinning. That boundary in space is what you're actually seeing, silhouetted by superheated material spinning around the event horizon at almost the speed of light. Sagittarius A* possesses 4 million times the mass of our sun and is located 26,000 light-years from Earth.

"Black holes have sparked imaginations for decades", said National Science Foundation director France Córdova, per CNN. And that means it converts nearby gas and matter into energy with 100 times more efficiency than the nuclear fusion that powers the stars. And when the German physicist Karl Schwarzschild wrote to him that year to raise the possibility of black holes and calculating the radius of their event horizons, Einstein initially dismissed black holes as a mathematical anomalies.

But researchers including astrophysicists at University College London (UCL), looked for the shadows cast by super-heated bits of space rock and dust as they tumbled into the black hole.

The amount of data generated was so massive that it could not be transmitted over the internet, so it was flown to data centers by jet. That equipment includes massive data storage capacity and atomic clocks that lose only one second of time every 10 million years.

"I was invited to join the Greenland telescope and EHT group because of my background and previous experience in radio astronomy".
