Why Supermassive Black Hole Doesn’t Destroy The Universe


Supermassive Black holes are an extremely powerful object in the universe. Every galaxy has some black holes and a supermassive black hole in the center. We will know in this article Why Supermassive Black Hole Doesn’t Destroy The Universe.

A new theory of supermassive black hole

Leonard Susskind theorizes in a hypothesis that the expansion does indeed happen, but happens within the hole. When it is not translated to an exterior diameter, it means the growth will not encompass the whole universe. Furthermore, even if everything would fall in, the hole can then keep its exterior size, when its interior dimension increases. Do you follow?
However, the current general model describes how an increase in mass will deepen the gravity well, and extend the event horizon proportionally. This means we have vastly different sizes of black holes out there. But there is no guaranteed positive correlation to the mass thrown in.

Understanding supermassive black hole deeper

Imagine water well in the backyard. It will be scary the deeper it is (and you can fill in more, the deeper it is), but it won’t suck in the house no matter how deep it gets. As long as its diameter in your garden remains unchanged (or changes just marginally), it doesn’t matter how deep it may be. A black hole is sort of like that.

The most widespread and best-known form is what we call a “Stellar Black Hole”. We defined them as medium-sized, and their mass is around 20 times that of the sun, with a volume of about 16 km in diameter. Imagine that. Stellar Black Holes form when a massive star collapses in upon itself. This collapse will cause a supernova, that blasts part of the star into space. But, in its former center, you will find your friend.

The Real Fact

However, we also have so-called “Supermassive Black Holes”. Those are the guys you find in the center of most galaxies, and their size varies. They are significantly a lot larger than Stellar Black Holes – a minimum of one thing like a hundred thousand times a lot of large about, and can even be as large as a billion times more massive.

They are formed at the same time as their surrounding galaxy. But the mechanics of them are still not quite understood. Perhaps they begin similarly as “Stellar Black Holes”, and then rapidly keep on feeding on the surrounding chaos – but, as I say, it is still an open question.
The smallest kind we call “Primordial black holes”. We call them that because their heyday was at the beginning of the Big Bang. Their theoretical existence could be a consequence of all the mayhem that went on. They were no bigger than an atom in size; however, their mass was typically that of a large mountain, but could also be no more massive than the average human.


Anyway, a solution is that space geometric inflation can happen within a hole, so will not have an impact on us, hanging around except the hole. And generally understood, Black Holes are deepening their wall and stretching spacetime down with them. And this might change their event horizon to some extent, but not in any exponential out-of-control kind of way.

An example may help

Even though the sun has much weaker gravity and a much smaller gravity well than a neutron star or a black hole, all of those three examples have more or less the same diameter in spacetime. And this diameter is what matters because we live on the surface – like the house in my above example.
