Black Holes in 2020: what do we know



These holes are not black

With the Nobel Prize in Physics announced Tuesday, discoveries focused around black holes were given acknowledgment and awards. This year’s winners for the prestigious honors are Roger Penrose, the scientist. He proved that black holes are a physically observable part of cosmic reality; Reinhard Genzel and Andrea Ghez discover a supermassive black hole in the middle of the Milky Way galaxy. But with these discoveries, and these scientists still pushing boundaries for science, what do we know about these cosmic bodies?

Debunking Our Misconceptions

In an article last year by Metro, they featured that NASA revealed misconceptions about the cosmic giant that most people got stuck in regarding their understanding and definition of a black hole.

People thought that black holes are black, which is wrong. NASA explained that processes are happening around black holes wherein it emits light or glow.

Black holes are not one-size-fits-all. Sizes vary from a tiny hole with mass fewer than the sun up to massive sizes more than 60 billion times larger than the sun.

Black holes will not slurp you if you are close to it. A safe distance of tens of miles will keep you from its gravitational pull.

There is no way out once inside the monster. NASA answered that radiation could escape a black hole.

We could have seen too many movies and television shows depicting black hole as this huge soul-sucking void in outer space. It is better to get our facts straight.

Black Hole in A Nut Shell

As summarized in CNN’s report on the Nobel Prize for Physics in the light of the discoveries revolving around black holes, here is what we know now about these mysterious objects as defined according to NASA.

Black holes are a section in space where a matter has collapsed in on itself. It has a powerful gravitational pull that nothing can run away from it, not even light. They can be borne out of some massive stars after they exploded. Their size could go as big as a million times the size of the sun. Its existence in the center of galaxies and its form is still a puzzle to the science community. Black holes are detected through the way they influence their immediate environment.

With all this information available on the internet, it might still be quite challenging for an ordinary person to understand a black hole. Thus the scientist continues effort to inspire everyone always to ignite their curiosity about these things.
