Nothing in the universe
moves at this speed
'cause infinity becomes their mass.
Everything around the black hole
gets sucked into it.
Black Holes have the escape velocity
faster than the speed of light!
The weather we experience on Earth
depends on the
distance of sun from us.
when a meteor enters our atmosphere
catches it fire, because of friction.
Friends, whatever I have just told you
all of them are "wrong"
and in this video we're gonna know why
and also the quantum origin of inertia
Number 1
Mass never increases.
yeah, you heard that right!
If you're in a car
and wanna travel at the speed of light
by accelerating it
then, your car can get
99.99999999999999
percent
or more closer
but will never achieve that speed of light!
Normal explanation for this,
goes something like this:
as the speed of car increases,
so does the mass
and using E = mc²
we need infinite energy
because the mass, at this speed
becomes infinite.
but wait,
it has one problem
this relativistic mass used here,
is pseudo concept
and this explanation is wrong.
The solution to this dilemma came 
400 years before
Einstein, from Sir Isaac Newton.
Law of Inertia
It says that
for any object to change it's speed
or direction of motion
it needs a "cause"
according to newton
this "cause" was the Force
which he described in
his second law of motion.
The textbook definition is simply
F = ma
in which you could substitute the
infinite value of mass
and prove mathematically that
see brother, you need infinite force
to travel at the speed of light
which is physically impossible
and because of that nothing
except light travels at this speed!
but wait, again all this calculation is
wrong
shocking right?
actually even the equation F = ma is wrong
it's the non-relativistic version
using which at high speed is illegal!
but for some reason, people still use it
which is the root of all this confusion and
misconception.
This is the relativistic version of force.
Looks ugly and complicated, doesn't it?
But essentially it tells us that
the inertia
i.e. the property of objects which makes it
resist the change 
in it's speed or direction
doesn't only depend on mass
but also on momentum or kinetic energy.
but if you're not satisfied
and wanna know,
what actually goes on at quantum level.
Answer to this was provided by 
"Balungi Francis"
in his book 
"Quantum Gravity in a Nutshell".
And he has also helped us alot
 in making this video,
So Big Thanks to him.
Mr Balungi believes that,
the inertia of a particle originates from
the electromagnetic interaction between
quantum fluctuation in zero point field and
that particle.
As the particle speeds up,
this electromagnetic interaction gets 
stronger
and as a result it builds up to a 
resistance
which we feel as
Inertia
Number 2
Everything doesn't get sucked into
 black hole
Nope
Black Holes only suck in those objects
which is at a certain maximum
distance from it's singularity.
This distance is known as event horizon
which is there in the form of a sphere.
Outside this event horizon, a black hole
behaves exactly like any 
other object of same mass.
So, for a moment
if you close your eyes
and try to find distinction between
a black hole and a star 
of the same mass.
Gravitationally, there won't be any 
difference!
Amazing right?
Number 3
Escape velocity of black hole is greater 
than the speed of light.
and because of that, even 
light can't escape.
Nope
Even the concept of black holes having 
an escape velocity is wrong.
For example
the escape velocity of our 
home planet Earth
is 11.2km/s.
It means, if you build a rocket engine
which somehow achieves this speed
and after that the engine fails or stops or
 whatever
even then, it will be able to escape 
earth's gravitational pull!
But sadly, none of our rocket engine 
is that fast or even close to it.
How then, ISRO did so many space missions?
Well guys, it's not at all important
that we move at this 
specific 11.2km/s speed.
There's another way,
Constant Thrust.
In which our rocket engine moves at a 
very particular speed
and try to maintain this speed.
But this is not at all 
the case with black hole.
Because the speed of light 
never changes here.
Instead this happens because the future 
of light (inside event horizon)
doesn't lie anywhere else but 
the singularity itself.
Number 4
weather change due to tilt
Our Earth moves around the sun 
in an elliptical orbit.
which is almost circular, because of which
the effective distance between 
the sun and earth never changes
Instead the weather change happens
is the 23.5° tilt
because of which when it's on this side
this part is closer to sun
and when it's on this side
this part is.
Number 5
Meteor doesn't catch fire because of 
Friction.
when a meteor enters our atmosphere
it always does this at very high speed.
because of which the air in front of it
doesn't get the change to escape
and gets compressed.
But since air is poor conductor of heat
all that heat goes directly to meteor
in turn increasing it's temperature.
which soon reaches it's ignition temp
and it catches fire.
Guys, wanna know a secret?
I also had this misconception,
which got cleared while creating this video.
Which one did you believe were actually true?
