EST and most mysterious phenomena in
science today is the black hole so
strange in fact that once you go through
one which would most certainly kill you
you will have left out the universe
entirely and enter someplace else that
can only be described as uncertain at
best it is a place where the laws of
physics as we know them break down and
if someone were watching you fall time
itself would appear to stop
at the center of most galaxies you will
find supermassive black holes the Milky
Way is no exception called Sagittarius
say this supermassive black hole lies
hidden in the shadows of the Galaxy's
Central core and while we've known about
its existence for some time the one
thing we've never been able to do is
take a picture of it or for that matter
any black hole we can theorize what they
might look like close up but even this
has been subject to change but the
current theory is that it should look
like a black dot surrounded by a Halo of
Light which represents the black holes
glowing accretion disk but from our
perspective Einstein predicted that it
may be more of a crescent than a ring
because one area of the disc appears
brighter than the rest due to a dramatic
Doppler effect on the light that's being
emitted but to know for sure what they
look like we must photograph a black
hole this has never been done they are
impossible to photograph the reason for
this is that they swallow light itself
leaving nothing but black but a radical
new telescope will be coming online in
April 2017 that may change that the
event horizon telescope isn't really a
single instrument but a network of radio
telescopes scattered across the world is
an array known as a very long baseline
interferometry or vlbi this technique
promises to provide unprecedented
resolution the telescope will go live
from the fifth through to the 14th of
April and intends to photograph the
black shadow of Sagittarius A
superimposed over its accretion disk
this is hard to do black holes for their
masks are very very small it's also very
far away at 26 000 light years and to
top it all off it's obscured by dust and
gas hoping to peek through the gas and
dust the telescopes will look at Radio
emissions from the black hole at a
wavelength of 1.3 millimeters or 230
gigahertz because there are so many
radio receivers focused on the black
hole the resolution will be
extraordinarily High allowing scientists
hopefully to Glimpse in the radio
spectrum of the Event Horizon of the
black hole think resolutions that could
spot a tennis ball at the distance of
the Moon
the vast amount of information gathered
will be processed and results are
expected to be available in early 2018.
in addition to Imaging the black hole in
radio Einstein's theory of general
relativity should predict the exact size
of the black hole based on how much it
bends space-time around it this will
either create yet another validation of
general relativity or throw the world of
physics into chaos if the prediction
ends up being wrong
