The Latest Discovery

This is what scientist predict black holes to look like

Heyyy. Have u all heard about the biggest discovery of mankind. Something really awesome that will transform our perspective about the universe we live in. Some may say it is just a blurry picture, some might just scroll past it. But if your a science lover like me, then you might as well be amazed. Prepare to be amazed too see the black hole. 

First of all, What is a black hole?

A black hole is a region of spacetime exhibiting such strong gravitational effects that nothing—not even particles and electromagnetic radiation such as light—can escape from inside it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole. The boundary of the region from which no escape is possible is called the event horizon. Although the event horizon has an enormous effect on the fate and circumstances of an object crossing it, no locally detectable features appear to be observed. In many ways, a black hole acts like an ideal black body, as it reflects no light. Moreover, quantum field theory in curved spacetimepredicts that event horizons emit Hawking radiation, with the same spectrum as a black body of a temperature inversely proportional to its mass. This temperature is on the order of billionths of a kelvin for black holes of stellar mass, making it essentially impossible to observe.

When was the picture taken?

This is what black holes really look like.

On April 10, 2019, the Event Horizon    Telescope collaboration released the first successful image of a black hole’s event horizon. The black hole in question comes from the galaxy Messier 87: the largest and most massive galaxy within our local supercluster of galaxies. The event horizon’s angular diameter was measured to be 42 micro-arc-seconds, implying that it would take 23 quadrillion black holes of equivalent size to fill the entire sky.

At a distance of 55 million light-years, the inferred mass for the black hole is 6.5 billion times as great as our Sun. Physically, that’s corresponds to a size greater than that of Pluto’s orbit around the Sun. If there were no black hole present, it would take light around a day to travel across the event horizon’s diameter. It’s only because:

• the Event Horizon Telescope has sufficient resolution to see this black hole,
• the black hole is a strong emitter of radio waves,
• and there’s very little foreground radio emissions to contaminate the signal,

Because of this, mankind were able to construct this first image of the black hole.
