"Black Holes Explained - From Birth to Death" explains in a movie an easy-to-understand explanation from the birth of the black hole to the annihilation

BySteve Jurvetson

Although it is the "black hole" that appears in various fields such as SF works, games and animation, there are a lot of people who do not know the formation and "what kind of influence actually affects around?" In order to explain the black hole in detail, physics and other specialized knowledge are required, but a movie to explain the black hole with a pop illustration "Black Holes Explained - From Birth to DeathIt is very easy to understand.

Black Holes Explained - From Birth to Death - YouTube


Black holes are special, many are enveloped in mystery. What will happen if it enters this?


A star is a huge gathering of hydrogen ... ...


Gas is solidified by gravity.


At its center, hydrogen fuses to helium and releases a lot of energy.


The radiation generated at this time and the gravitational force balances to form a star.


As long as they are fused, the star's nucleus will stabilize, but if the star is heavier than the sun ......


Elementary heavy elements are made at the center of the stars in order, and finally iron is formed.


Unlike other elements, iron alone does not emit energy during fusion.


When the iron is made to the limit in the nucleus ...


The balance between radiation and gravity which had been stable until then ... collapsed ...


The core breaks and the stars shrink in a moment.


At this moment other heavy elements are made ......


Mass gathers in the nucleus at a rate of a quarter of the light.


And "star's death"Supernova explosionIt happens.


After the supernova explosion, the super high temperature ultra high density "neutron star" remains in the center of the star. If this neutron star is sufficiently heavy ......


A black hole is born.


However, what actually looks like is not black holes but "Earthquake of eventsWhat is called.


Because we need to go faster than light to pass here ...


It is practically impossible.


The plane of this event is pitchless as it does not emit any light. As the name suggests, it is "black".


Then what is the "hole" of the "black hole"?


This shows a singular point deep inside the black hole.


Although the substance of the singular point is unknown, it is thought that all masses are collected at one point with infinite density.


However, since everything is unknown, it is like dividing by 0.


Because the black hole does not inhale as anything as a vacuum cleaner ......


Even if you change the sun into a black hole ......



It seems that the earth only freezes, there is no other change.


So what happens when we enter the black hole?


Because the flow of time is different in the black hole ......


When going into ... ...


It gradually falls slowly, it stops at a certain point, the end turns red and disappears.



At this time, from the one who entered into the world seems to see the world fast forward.


There are two ways to go beyond that.


One is an instant death.


The black hole bends the space too much and the direction is gone ... ....


It can only proceed in one direction in the plane of the event.


It seems that this is like a narrow road to close.


Furthermore, due to mass concentration on one ... ...


Even with a width of several centimeters, tens of thousands of times different gravity will work ... ...


Cells are pulled apart and split ... ...


It will be broken down into atomic levels.


Another way is "super-instant death".


At the moment beyond the plane of the event ......


It strikes a wall and dies.


The speed of death depends on each mass ......


When the mass is small, it dies in front of the plane of the event ... ...


When it is big it is possible to travel inside.


It seems to be able to live for a certain distance from the singular point.


There are various sizes of black holes, varying from small mass to something smaller than the sun.


The super huge black hole has grown to hundreds of millions of years in the center of every galaxy ... ...


The largest one currently being observed ......


What is called "S5 0014 + 81". It has 40 billion times the mass of the sun ... ...


The diameter is 236.7 billion kilometers, 47 times the distance from the sun to Pluto.


The black hole evaporates from its strength with Hawting radiation.


Looking at the space in the sky ......


Here two pairs of virtual particles are generated and annihilated.


However, at the edge of the black hole, one of the virtual particles which was supposed to be generated and annihilated will be sucked in and the other escapes to the outside. As a result, energy is lost.


The smaller the mass of the black hole is, the faster this speed ... ...


Whereas the mass of an asteroid is about as high as room temperature, ....


If it is mass of mountains it will deliver as much heat as the sun.


And in the last moment ......


A large explosion on the scale of several billion times the nuclear explosion.


However, if this process is gentle and maximum it will be 1GoogolIt will take years.


This is too long, so life can not exist at the time of evaporation, so no one will be able to see it.
