WHAT ARE BLACKHOLES? - IS EARTH ENDANGERED?

Blackholes are spots in space where gravity pulls in so heavily even light can not escape. Matter is squeezed into tiny places causing the gravity to be greatly intensed. They are like places of no-return. Blackholes can be so small (small but definitely mighty) or so big, a millions times bigger than the Sun. The smallest blackholes can be as small as an atom but can consume a mountain, so you can imagine what the big Black-holes would do, if you’re thinking what I’m thinking, then ofcourse, it would swallow a whole galaxy.

HOW TRUE ARE THESE BLACKHOLES
Some might think that the idea and theory of blackholes might just be myths and hoax, well unfortunately, they are very true. A blackhole can not be seen easily because the light they are viewed with gets sapped into it so light can not detect it. Thanks to scientist who have made special telescopes that can view these mysterious outer space phenomenons. Black-holes are real and it’s no news.

HOW ARE BLACK-HOLES FORMED?
One would imagine the question, what in the world would create this space action? Well the answer is obviously way bigger than the world. Black-holes are created when center of huge stars give out, leading to a Supernova causing blackholes are formed. Supernovas are massive explosions of hugely astronomical stars. Even the Sun is not worthy enough to form a blackholes if it explodes, reason being that the Sun is so small compared to the massive stars that cause these great phenomenon of black-holes, so in clearer terms, the Sun is not big enough to form a blackhole.
There are two other mechanisms discovered to create astrophysical blackholes; when two neutron stars collide (or merge), if their combined post-merger mass is more than about 2.5-to-2.75 solar masses, black holes can be result.

Bringing us to the much awaited question.......
ARE WE SAFE FROM BLACKHOLES?
Yes we are safe, thanks to our solar system. Although we have a huge blackhole present in our Milky Way, called Sagittarius A and it is located at the very center of our Milky Way. But then we are no where close to it. And even if the Sun (which cannot form a blackhole) dies out and turn into a Blackhole, Earth is still going to revolve round it as it did with the Star (The Sun) itself and not get consumed by it.
