Once, the famous astrophysicist Neil
de Grass Tyson put it briskly that if a black hole
visits us, the solar system would have a badday.
After all, there is hardly anything worse
than the ability to be broken into atoms.
But we are used to thinking that black holes are somewhere far away,
in other parts of the universe.
But what if one of them literally appearson our doorstep.
What happens if a “ uninvited guest ” with a size
of 1 mm “ settles ” near our Earth?
Physicists asked a similar question in 2008,
when the Large Hadron Collider was launched.
Then, many scientists among whom was also Stephen Hawking,
feared that this greatest invention of mankind could create a multitude
of microscopic black holes that would swallow
everything around and we would cease to exist… forever.
Moreover, these are far from the only problems
that were predicted by the opponents of the collider.
However, more than 10 years have passed since then,
and if you are watching this video,
it means that the Large Hadron Collider
works quietly away by itself
and doesn’t create any dangerous pieces capable of destroyingthe Earth.
Or is that just for now?
In fact, to produce a mini black hole,
you need 1015 times more energy than the Large
Hadron Collider can withstand.
But even if we manage to use such a huge amount of energy,
to create a micro black hole
we would need to work with the 4th dimension in space,
which in this context isn’t particularly
well studied or understood.
But suppose we miraculously manage to
create a microscopic black hole
in our limited and wretched 3D world.
I hasten to upset those who are looking forward to the apocalypse.
It would have to be postponed for some time.
Because in this case,
the mini black hole is most likely to instantly evaporate, thanks
to so-called Hawking radiation.
After all, black holes not only absorb energy,
but also give it away! So,
the Large Hadron Collider does not threatenus at all.
At least in any case,
until the time we learn to use a large amount of energy and fully
explore the 4th dimension in space. However,
microscopic black holes can occur even without the Large Hadron Collider.
The fact is that right now billions of black holes pervade our planet! So,
what is happening?
Are we doomed,
and the earth would soon be torn apart into small pieces by mysterious,
space objects? Relax, it’s not so bad.
At least for now…
After all, our multi-million army of black holes has been attacking our
home planet for billions of years!
At the same time,
the mass of individual black voraciousness’s could reach up to 100 tons,
but their size isn’t more than an atom!
Such a small diameter gives rise to a
correspondingly small “ event horizon ” —a hypothetical
line beyond which space and time are bent,
and matter begins to be absorbed and torn apart by atoms.
For this reason,
the mini black hole can’t devour even the bacteria on your dining table.
But even if it starts to eat our home planet,
it would take a very long time
-several billion years in fact.
By this time, humanity is likely to have become extinct,
or else it would have found another
place of residence in the universe.
不过 还有一个顾虑 如果迷你黑洞的直径
However, if the diameter of a mini black hole
increases to a size visible to the naked eye
events would turn out completely differently.
We won’t baffle your brains with complex calculations
from the strange world of higher physics,
but according to calculations,
a black hole with a diameter of 1 mm would have
a mass of more than five lunar masses combined,
which is about 11 % of the Earth’s mass.
The scale of the influence of a black holedepends on where it is located
on the surface of the earth,
or in the center of the planet
or for example, in the room of the guy you hate.
Suppose that a black monster, 1 mm in size,
is located on the surface of the Earth.
The sphere of influence of a black hole would be
about a third of the Earth’s radius,
about 1,320 miles (2124 kilometers).
This would lead to a noticeable increase in the overall gravity
of the Earth, which in turn would affect the orbit of the moon.
It would stray off the current course
and begin to move into an elliptical orbit. But,
if the Moon only changes its course and remains alive,
another and more terrible fate
would await us and all matter in close proximity to this monster.
If we were close, we would’ve been tornto pieces.
And it would happen so quickly
that we wouldn’t even have time to blink an eye.
Having settled with us,
the black hole would purposefully move to the center of the Earth
and nothing and no one can stop it.
Without common obstacles,
it would absorb everything and reach the center of the Earth in just 42 minutes.
An insatiable monster passing through the core of the earth and
in about the same time
it would reach the other side of the surface.
But the black hole, too, wouldn’t standstill.
If its relative speed is at least 12 km / s,
or 7.5 miles / s, it would rotate around the
Earth along with its sphere of gravitationalinfluence.
With each circle, the earth would losemass.
Thus, the black hole would begin its meal:
absorbing the crust and most of the mantle.
It means our complete destruction and destruction of all life
on the surface of the Earth.
But before absorbing all living things,
the black hole “ smoothes out the corners ”
Apparently, to make it easier to eat.
Thus, the gas would twist into a gravitational spiral,
like sugar during the creation of cotton candy.
And our planet would turn into just a broken disk of hot stone.
The material of the formed disk would produce a lot of heat
It is assumed that it would have
a temperature of six thousand Kelvin
like the Earth’s core or
the surface of the Sun.
Because the disk would be radiating, as if highlighting a black hole.
It would be an amazing and at the same time eerie sight,
because a black hole, like a vampire,
would suck the radiance of its energyfrom the planet.
Scientists believe that the space monsterwould take 5 billion years
to finally eat our home planet.
During this time, the mass of the Earth wouldincrease significantly.
But the shape of the planet familiar to us would change beyond recognition.
It would probably be similar to the fall of the legendary Pompeii
which was wiped out by burning lava
only on a cosmic scale.
In just a few hours,
the beautiful and densely populated Blue Planet would turn into
an uninhabited shred of space
where only the collapsing crust, lava and hot gases would reign.
Naturally the disappearance of the Earth wouldn’t pass without a trace
the asteroid belt would collapse
which would lead to frequent collisions for a million years
in the solar system.
To complete chaos, there would be no place for life,
which simply becomes impossible.
So far these are only terrible assumptions and theories,
but they are still far from us.
In any case, humanity still has a head start
in 5 billion years to build the Noah’s Ark
and move to some other planet.
And maybe in another galaxy,
because it’s far from fact
that the Solar System can live for so long.
But for now, you can safely allow billions
of mini black holes to permeate you
Without fear of breaking into atoms. Although…
it would look kind of spectacular!
