The Universe...an Anomalous Bluster of Bosons
and Fermions, Protons and Neutrons all Bouncing
around in Ineffable Glory.
Its Home to Many Astounding Wonders Of Space
and Time.
Hey Guys...So Let's Explore one of these Cosmic
Stunners, Black Holes...
Large Cosmic Bodies like Stars are Collections
of mostly Hydrogen and Helium Atoms.
These Stars Burn up these Reserves Of Fuel
and Collapse Under their own Gravity.
In their Core, Nuclear Fusion Crushes Hydrogen
Atoms Into Helium Releasing a tremendous Amount
Of Energy which, in the form Of Radiation,
Pushes Against the Force of Gravity maintaining
a Delicate balance between the two Forces
and keeping the Star Stable.
But as time progresses, the Core Fuses Heavier
Elements like Carbon, Neon, Oxygen, Silicon
Until it Reaches Iron.
Iron Doesn't Fuse Further and Hence Emits
no Radiation.
It Slowly Builds Up in the Centre Of the Star
Until the Balance between Radiation and Gravity
becomes lopsided.
The Core Collapses and in the Fraction Of
a Fraction Of a Fraction of a second the Star
Implodes Into a Supernovae Explosion.
This Cosmic Phenomenon Produces Either Neutron
Stars, dense Celestial Objects Made up Of
Sub - Atomic Particles called Neutrons.
A Neutron star is so dense that one teaspoon
of its material would have a mass about 900
times the mass of the Great Pyramid of Giza.
Its density is therefore a hundred trillion
times the density of water; at that density,
all the people on Earth could be fit into
that Very Same teaspoon!
And Finally, If the Supernovae is Massive
Enough, It can Produce a Stellar Mass Black
Hole.
When you Look at a Black Hole, you'd be actually
seeing the Event Horizon.
A Boundary in Space time through which nothing,
not even Light, can Escape.
For any Information to Escape out Of the Event
Horizon, it needs to be travelling faster
than the Speed Of Light and, is therefore,
Impossible.
So we Just see a Black Sphere Reflecting Nothing.
Now, what is inside a Black Hole?
For most part, we don't really know.
At the Centre Of Each Black Hole, there Exists
a Singularity, a Reign Of Infinite Density.
Or, Maybe not.
It's Like a Schrodinger's Cat Situation.
To Really Know the Truth, you'll have to Pack
Up those New Sneakers your momma bought you
for Christmas, take a deep breath and Jump
Right Into a Black Hole to Find Out.
Not that it Would help, anyways.
The Experience Of Time around a Black Hole
is Completely Different.
To an Outside Observer, you Would Seem to
Slow Down, freeze in Time and Slowly Disappear.
While from Your Perspective, you Could see
the Outside World in Fast Forward, much like
seeing into the Future!
Anything Could Happen Next.
You'd be able to travel For Quite a While
inside the Event Horizon but Soon After that
you'll be Pulled Into a Firewall or an Infinite
Rollercoaster Of Space and Time or Be Pulled
into the Singularity to meet your Maker.
I Don't Highly Recommend the Experience.
The Idea that Black Holes Exist was First
Put up by Reverend John Mitchell in the Eighteenth
Century.
Modern Day Physicists Like Stephen Hawking
have Contributed Immensely in this Field Of
Astrophysics and Quantum Research.
Hawking now Hypothesizes that Instead Of Event
Horizons, there Exists Something known as
'Apparent Horizons.'
Anyways, Scientists claim that there are thousands
Of Millions Of Black Holes In Our Galaxy Alone.
They Can be detected as they Don't Let Light
Escape and also through Gravitational Waves,
which can Cause Ripples through the Very Fabric
Of Space and time.
Black Holes Come in all Kinds Of Sizes.
They Can be as Small as the Penny in Your
Pocket Right now, Or, they can be the Super
massive Black Holes Found at the Centre Of
Most Galaxies.
In Fact, at the Heart Of Our Very Own Milky
Way Galaxy lies a Super massive Black Hole.
Sagittarius-A, as it is called, is 14 Million
Miles across.
We Keep discovering New Ones Every day.
The Largest Black Holes We Have Found have
Masses more than 50 Billion Times that Of
Our Sun.
But as Amazing as these Black Holes are, they
will be Eventually be Wiped Out Someday.
This Happens Due to a Process called Hawking
Radiation.
To Understand this better, we need to take
a Look at Empty Space.
Empty Space Isn't Really Empty but Full Of
Virtual Particles, Transient Fluctuations
in Space-Time.
These Virtual Particles keep Popping into
Existence and Cancelling Out Each Other.
When this Happens at the Event Horizon of
a Black Hole, One Of the Particles( The Negative
One) Falls Into the Black Hole and One Escapes
Out.
This Causes Black Holes to Lose Mass.
But Don't worry-eh!
This Process is Extremely Slow and the Greatest
Of Super massive Black Holes may Take Googolians
Of years to Die Out.
Theoretically, anything can be Converted Into
a Black Hole, Even You.
You just needs to have your Mass Compressed
Enough.
So, at the End Of this all, what Really Is
a Black Hole, what-what purpose does it Serve
Even.
Is it just a Worm-Hole, a Gateway to Another
Universe.
Or Is it a Time Bomb Waiting to Explode and
Spawn a Universe Of its own.
We Don't Really Know.
Perhaps Our Very Own Big Bang Came Out Of
a Black Hole In another much Larger Universe.
There are Loads Of Crazy Ideas Out there,
and I'll be Sure to keep Exploring them now
and then.
