hello wonderful person this is Anton and honestly a few hours ago I got super
excited because I just heard that we've received one of the first images of the
area near the supermassive black hole at the center of the galaxy and the
scientists released the images of what they've discovered so the reason I got
excited is because for the longest time now we've been actually waiting for the
first ever image of the supermassive black hole and I actually thought the
news is coming from the famous event horizon telescope the telescope that for
about two years now has actually been analyzing the data collected from
several dozens of telescopes around the world in order for us to actually get
the first-ever image of the black hole but turns out it wasn't really coming
from that particular team so it kind of made me a little bit sad but
nevertheless though we actually now have a much better picture of what's
happening in the middle of our galaxy where the supermassive black hole is and
the image we've received has actually being the most accurate and also the
highest resolution of all of the images we have so far now let me actually tell
you what we've seen but before that let me tell you a little bit about what was
predicted to see so back in the seventies an astro physicist by the name
Jean Pierre Luminex predicted that the black holes at least massive black holes
that have an accretion disk would look something like this now this was
actually done way way before any computer simulations it was actually
done practically by hand although he did use a very interesting technique for
this he used an IBM punch card from 1960s
that was able to actually create this beautiful image based on the mathematics
that he had himself created now obviously today we have much better
simulations as a matter of fact one of the more recent black holes and probably
the most famous ones is from the movie interstellar the black hole that forms
pretty much the center of the movie very very impressive extremely extremely
beautiful but according to Luminex and also according to the scientists who
essentially created this for the movie Kip Thorne this is not really the most
realistic black hole in the world as a matter of fact it is very simplified and
very simplistic here is actually a much much more accurate representation of
what a supermassive black hole might look like and as you can see what's
important to notice here is that let me actually just remove the camera for a
second it's not symmetrical it has different sites that are actually
different in luminosity as a matter of fact this side here is brighter than
this side because the actual flow of matter goes this way and when the matter
comes toward you its luminosity is increased because of the Doppler effect
and when the matter moves away from you the luminosity decreases as does the
actual color so there's a water blue shifting going on on this side and a lot
of red shifting going on on the other side another good representation is
right here showing you how unsymmetrical or I guess not symmetrical a typical
supermassive black hole would be so this is what we actually expected to see in
the center of our own galaxy and this is what most scientists belief is probably
happening there on the other hand we also think that the size of the actual
supermassive black hole or at least the size of radiation around it would also
be very large and so it really surprised many scientists when the results that
were just released from a paper that you can find in the description below that
that's really not what we saw at all so um the actual paper is not super easy
and there's actually a lot of a lot of descriptions and explanations here that
don't really show you any actual photos of the black hole but the results in
essence show us this now ignore the actual rings here that's drawn by a
person and what this shows you is the radiation that was recreated in a little
radio wave frequency specifically 86 megahertz
in the center of our galaxy now it's sort of similar to what we expected
but there are two major differences first difference is that we thought this
would be much much bigger we thought it this is going to be huge it's much
smaller it's actually way smaller than we expected on the other hand we like I
previously showed you expected this to be a symmetrical part of it being bigger
the other part being smaller and that's also not what we see at all as a matter
of fact this is very very symmetrical and very unusually so and for this
reason this will create a lot of debates in the future this will probably create
new theories new speculations but what a lot of scientists think now is maybe
this can be explained in two different ways first way let me actually show you
using the actual black hole is that somehow the radiation is actually coming
straight from the disk itself but the disk is somehow not really spinning in
the way where we would see the actual red shifting and blue shifting in
other words it's basically either almost completely still and the matter just
basically Falls indirectly releasing the energy symmetrically but that make our
own supermassive black hole extremely rare and sort of not easily explainable
it's probably not really a good explanation the other explanation which
is also not super good is that we're actually staring at our black hole right
from this angle here basically from the top and what we're seeing is well we're
seeing the actual jet and that would be a pretty good explanation for why it's
so symmetrical but the chance of that happening the chance of us staring
directly at the jet is also very minimal and if we're staring at a jet that
actually means that there could be some serious percussions as a matter of fact
the fact that our actual solar system moves around the galaxy also means that
we're not always going to be staring directly at the jet unless it's
literally following us and that's also very unlikely
so in since we don't really know what's
happening there and we have definitely no idea why the images that we'll
receive so far don't look like this but instead look like this um at the same
time this is still not really the best most accurate study yet because the
event horizon will most likely beat all of this as soon as we get the results
but I guess not just yet also a little bit more about this particular study
well first of all these are actually the telescopes that participated here and as
you can see they basically connected together into this huge mega telescope
virtual mega telescope that was approximately eight thousand miles or
about twelve thousand kilometers in diameter and this obviously took a lot
of data analysis it took something like million gigabytes of data of analysis
and the biggest problem with this analysis was that these scientists
actually had to find a way to disregard the interstellar scattering basically
the effects of different stars because they usually blurred the data and also
make the data very difficult to read and once they found a technique to prevent
the stars from interfering and basically prevent any kind of interstellar
scattering they were able to actually create several relatively accurate
images that you see right here that were relatively easy to analyze and in some
of the future studies they're actually planning to do another observation at a
higher frequency and hopefully even see the shadow of the black hole as well but
I guess our biggest hope right now is that we're actually going to hear back
from the event horizon telescope sometime soon understandably it does
take a long long time to analyze all this data and this probably tons and
tons of problems that they have to deal with because of the amount of actual
data points that were collected and the fact that so many people that are
working on this basically don't even live in the same countries and don't
speak the same languages to make this slightly more difficult and slightly
harder to to deal with but nevertheless though we're gonna patiently wait for
the actual first-ever image of the black hole but for now well
we now have a slightly better understanding of what's happening at the
center of our galaxy and it's really not what we thought as a matter of fact um
it's kind of very interesting in somewhat mind-blowing because we really
thought we understood black holes at least mathematically but this image
right here looks pretty much nothing like what we predicted and for this
reason we might need to sit down and think about it once again and anyway on
that note that so I wanted to show you this video unfortunately maybe not the
best news we could have had about the actual image of the supermassive black
hole but honestly um the fact that we discovered a new mystery makes this
somewhat more interesting actually so let's wait and see on what's really
happening here because if we're literally staring at the jet of our
supermassive black hole that actually is somewhat concerning anyway thank you so
much for watching come back tomorrow to learn something else and make sure to
subscribe if you haven't because we're going to come back and talk about this
in a few more months because hopefully by then the event horizon telescope will
finally release that picture I've been waiting for anyway
I'll see you guys tomorrow space out and as always bye bye and thank you so much
