Black
Holes: The Wonder of Cosmos
Hello,
its been a while since I have written a blog post. This time I am going to give
light on black holes that are so mysterious topics in advanced physics.
Black holes can be defined as a body with
immense gravity and where escape velocity is speed of light. Black holes are
formed when stars collapses and creates a super nova exerting immense amount of
radioactive energy from their core. They got their name black as light also
bend and is absorbed by the hole resulting in zero visibility.
Singularity
and Quantum Space
Black
has a center point where all of its mass is stacked and compressed to a size
smaller than atom. Black holes can only be formed when gravity of the star’s core greater enough to crush everything, it
crushes the hole stars mass and compresses it to the size of singularity. It is
believed that singularity may be small to the size of Plank’s length. The
tremendous energy of star is enough to squeeze the wavelength of every particle
to almost nothing.
Event
Horizon
Every
black hole is surrounded by the event horizon. It is a horizon surrounding the
black hole where the possibility of even small happenings becomes extinct. No
one can see what might happen inside the horizon. The escape velocity also
increases as we go deeper towards the horizon. At Event horizon the escape velocity
turns 1c that is speed of light. So we can say that singularity is the physical
grave where nothing physical can come out.
Tidal
forces
When
any object fall towards the black hole it stretches or compresses because of
the tidal gravity exerted by the hole. Well, of course no one can enter the
hole but still if we assume that a rocket is launched from the earth to nearest
black whole. This space rocket is super advanced that it can enter the black
hole, when it enters the horizon it starts moving faster towards the holes
center, it stretches and squeezes. As far as the travellers are concerned they
will may be get crumbled or Spaghettified (That’s what this stretching and
squeezing is called).
Time’s
Death
Inside
the black hole at it’s horizon the travellers inside our rocket feel as
that the time starts slowing, they will move as faster as they can towards the
hole but as soon as they reach the hole they will trapped as the time is
stopping because of black holes immense gravity.
