What Does The Inside Of A Black Hole Look Like
it would be the trip of a lifetime
one you surely could not survive
through
a point in space in which time has
no
meaning and even the fastest
particles
cannot escape you are of course
travelling into a black hole for
this
journey one assumption needs to be
made
you are merely an observer not a
physical being falling into the
black
hole
meaning the effects of gravity and
energy do not interrupt your
observation
with this unrealistic foundation
set
into place let's take a look at
what the
inside of a black hole really looks
like
starting off the approach would be
quite
beautiful although considered dark
spaces dotted with colorful faraway
worlds that seem to infinitely
illuminate space around you except
for
of course the ominous pitch-black
sphere
that is your destination the sphere
can
be considered a waterfall of light
the
edge of this waterfall where light
cannot even escape is crisp and
defined
only by the warping of light behind
it
as you accelerate toward the event
horizon you pass through the photon
sphere in this region the photons
reflecting off your body begin to
orbit
the black hole when they make a
complete
orbit they return back to your eyes
allowing you to see the back of
your
head the closer you approach the
more
distorted space appears behind you
until
it appears as if you are standing
at a
window to the universe by this time
of
course you have been accelerated to
a
meaningful fraction of the speed of
light but this is only the
beginning as
Charles Liu of the American Museum
of
Natural History's Hayden
Planetarium
describes it the faster you move
through
space the slower you move through
time
the farther you travel into the
black
hole the greater effect time
dilation
will have on you your time will
tick so
slowly that if you were to look
behind
you you would see everything that
will
ever fall into the black hole
behind you
similarly in front of you objects
experience higher time dilation
meaning
you can see everything that has
since
fallen into it in the past as
Charles
Liu stated you'll get to see the
entire
history of that spot in the
universe
simultaneously from the Big Bang
all the
way through the distant future
this is short-lived however as the
event
horizon begins to surround you
until
only a tiny point of light behind
gets
blue shifted through the
ultraviolet
spectrum and become
invisible at this point however
your
eyes will see no more this is when
things get incredibly interesting
or
incredibly dark since matter is
stretched and pulverized into their
fundamental building blocks the
properties of atoms that give them
texture shape structure and color
are
completely thrown out the window
the
quarks and gluons are compressed in
position space and expand
proportionally
in momentum space with all paths
pointing toward the singularity
there
are no properties that can describe
what
this would look like because the
properties we attribute to things
exist
in our space-time but not in the
space-time of a singularity it's
better
to consider black holes as a
feature of
space with a Planck length diameter
as
opposed to a traditional object so
if we
can't see what a black hole looks
like
from the inside why can't we see it
from
the outside aside from the fact
that
light exiting a black hole is
redshifted
into oblivion
the ultimate crunch of the black
hole
never really happened from an
outside
observer time is frozen at the
event
horizon relative to their clocks
anything beyond the event horizon
is no
longer a part of the timeline of
the
outside universe nothing occurs beyond
the event horizon so this is the
best
look at what the inside of a black
hole
looks like the truth is from the
outside
the singularity never occurs and
from
the inside the singularity does not
possess any meaningful properties
or
characteristics to a human observer
beyond its size although there is
no
meaningful answer to what the
inside of
a black hole looks like every year
space
agencies around the world are
discovering new and interesting
features
of the universe and answering our
questions in more detail
