Black Hole: Let's Get To Know More About it!
Black holes are forged from the small, dense, remnant cores of dead stars. The black hole is fascinating, mysterious and deadly.
Something is chilling about the phrase "black hole". It incites feelings of danger; mentioning something that could pull us in and entrap us. A place where time means nothing with stunning qualities that we struggle to grasp
How are they made?
Black holes are made from the small, dense, remnant cores of dead stars. If the core's mass is more than about three times the mass of the Sun, the force of gravity overwhelms all the other forces, and the remaining collapses and produces a black hole.
Black holes are made from extreme density and the amount of mass they have means they have intense gravitational force even light gets trapped.
There are three types of black holes:
Steller-mass black holes are made when the centre of a big star falls in upon itself or collapsed. when this happens it causes a supernova.
Supernova is the explosion of a star, the centre of a larger star collapses.
The largest, known as supermassive black holes, can have masses that are millions if not billions of times the mass of the Sun. This type of black hole reaches its enormous size by merging with other black holes.
The largest, known as supermassive black holes, can have masses that are millions if not billions of times the mass of the Sun. It is thought that this type of black hole reaches its enormous size by merging with other black holes, as well as by subsuming stars.
Why are they important?
Black holes not only explain the seemingly chaotic movements of some stars and help make sense of our galaxy, but they represent a new realm of physics for scientists.
When we look at the centre of a black hole – the ‘singularity’ – it gets complicated. A black hole is so dense that it warps the spacetime that surrounds it.
Can we see them?
Black holes have such an immense gravitational force that not even light can escape, so they cannot be seen directly. As a result, huge radio telescopes and gravitational wave detectors are used instead of conventional telescopes.
Black holes can be located by the effect they have on what’s around them – they suck in gas, dust and stars, which become superheated and emits radiation that can then be ‘seen’ as a heat image.
What would happen if you fell into one?
So, the big question – what would happen if you fell into a black hole?
Well, the medical condition isn’t great, to be truthful, whichever sort of black hole you picked. The black hole’s gravity force would compress you from top to toe while stretching you at the same time.
A supermassive black hole has a slightly less horrendous effect.
Put simply, if a black hole sucks things in, then a white hole spits them out again – wherever that may be – and the two are connected via an inter-dimensional tunnel, known as a wormhole. Or, it’s also hypothesised, if you waited long enough, the black hole will turn into a white one, anyway.
This process is thought to take billions of years, but there’s no reason to be disheartened.
Reason?
Well, due to the intense gravitational forces within, time would be speeded up for you – so it would be over in a matter of milliseconds. Of course, at present, this is only a theory.
Conclusion: Considering our galaxy alone holds 100m stellar-mass black holes – and that our galaxy, the Milky Way, has a supermassive black hole at its centre so enormous that it would fit inside the orbit of Mercury maybe it’s time we started to learn more about these enigmatic phenomena. At least, just in case we ever find ourselves about to fall into one.
