Falling Into a Black Hole Creates Two Separate Realities
It could happen to anyone in the future. Maybe you will want to find a new habitable planet for the human species, or maybe you will crash your spaceship into a black hole.
For the purpose of this article, let’s assume that you somehow fall into a black hole:
What happens if you enter the event horizon of a black hole?
You might think you’d be crushed by the black hole’s powerful gravity, but in reality, stranger things will happen to you. Because the black hole splits reality in two.
In one, you fall into the black hole and burn up. On the other, you enter the black hole unharmed and feel no pain until you fall into the singularity at the center of the black hole.
Moreover, according to the principle of complementarity in physics, both physical realities are happening at the same time in the universe.
If you ask how two opposite realities can exist at the same time, the reason is that the laws of physics cease to work in the singularity at the center of the black hole.
Strange But True
Einstein taught us that gravity bends space. In this case, a sufficiently massive and dense celestial body can tear the spacetime that makes up the fabric of the Universe and tear a hole in the vacuum of space.
We call this a black hole.
Black holes are formed from the remnants of the cores of massive stars that end their lives in supernova explosions.
As the star collapses in on itself, it also collapses into space-time.
The strength of the star’s gravitational field becomes so strong that not even light can escape, creating a black hole.
Point Of No Return
The outer boundary of a black hole is called the event horizon, and to escape its gravitational pull, you have to go faster than light.
Since nothing can go faster than light, light cannot escape falling into the black hole. The event horizon marks the point of no return.
On the other hand, Stephen Hawking showed that the event horizon, though dark, generates a strong radiation field:
Quantum effects create power currents of hot particles flowing outward from the edge of the event horizon.
This is how black holes emit radiation into space. Hawking radiation, named after Stephen Hawking, causes black holes to lose mass and evaporate over time.
Space Flows Faster Than Light When Falling Into a Black Hole
Have you ever wondered why we have to go faster than light to escape after falling into a black hole?
The reason is that not objects, but space itself, flow into the black hole faster than light, dragging the objects above it with it, like a canoe falling down a waterfall.
Black holes bend space, creating a real hole. This causes space to fall into the black hole faster than light. At the center of the black hole, the bending coefficient of space reaches infinity.
Scientists call the infinity at the center of a black hole a singularity.
Space Disappears and Time Stops
What is in the singularity?
Is the Singularity a gateway to other universes?
Or is it the end of everything?
Is it God’s residence if you believe in the Creator, or is it the back of the book of mysteries?
We don’t know that.
But notice that in the first two steps, we tried to explain why we don’t know what will happen to you if you fall into a black hole, but that doesn’t stop scientists from speculating.
So let’s ask again what happens to an astronaut who falls into a black hole, and this time let’s speculate.
Do We Disintegrate Into Ashes As Soon As We Reach The Black Hole?
Just as it reaches the event horizon, we freeze.
It’s as if someone paused the camera recording. Our body stretches like chewing gum on the black hole’s round surface before its atoms are torn apart and shattered by the black hole’s powerful gravitational field.
Then the rapidly increasing heat begins to fry the astronaut. Since time freezes at the event horizon, we don’t see how it disappears at that moment.
But he sees in slow motion how she stretches and heats up like spaghetti until she reaches the event horizon.
We Fall Safely Into The Black Hole
But don’t rush to the funeral, and please put the bad ending out of your mind for a moment and remember what I wrote in step 2:
Black holes split physical reality in two. We have just described the end of Smurf in the first reality. Now let’s tell how she survived in the second reality, at least until she reached the singularity.
To make it easier for us, we have taken a round, stellar-mass black hole that does not rotate around itself.
Normally, it takes less than a second to cross the event horizon and reach the singularity in this kind of black hole, but as I said, we are slowing it down.
So we can tell what happened to Shirin in the second reality: Nothing. She crosses the event horizon and enters the black hole with nothing and unharmed.
Time Not Space, Attracts Singularity
Einstein’s theory of relativity says that matter can transform into energy and energy can transform into matter.
This is the meaning of the famous formula E=mc2.
On the other hand, this means that space can be expressed in time and time in space.
It means that the black hole that bends space also bends time.
And we cannot repeat it enough, the gravitational field inside a black hole is so strong that even light cannot escape.
That’s why space and time are geometrically displaced inside the black hole.
I won’t go into detail in this article, but the blue line in the picture is space and the gray surface is time.
This is why you have to go faster than light to escape the black hole. Going faster than light means going back in time.
But you can’t go faster than light, you can’t go back in time, the effects don’t precede the causes in causality, and you can’t get out of the black hole.
