infinite nothingness completely cut off from the rest of the universe black holes continue
to entice and surprise astronomers with every new discovery about them astronomers
may have just added a new object to this list nearly undetectable free-floating black holes
thank you in June of 2022 astronomers led by a UC Berkeley team have possibly detected
the first free-floating black hole found in our galaxy there are an estimated one to two hundred
million black holes in our galaxy alone and some of them are thought to be Rogue black holes that
are much harder to spot due to a process first described by Stephen Hawking a black hole does
not emit any radiation itself due to its massive gravitational pull and is therefore invisible to
our normal forms of detection but luckily many black holes hold a ring of dust and gas around
their bodies with their extreme gravitational pull called an equation disc even some Rogue
black holes hold on to their accretion discs after breaking out of its system this secretion disc has
played a major role in the traditional search for and detection of black holes they have been found
by scanning the skies and finding the radiation being admitted by a black hole secretion disk
as gases and dust around the cloud matter begin their fall Beyond The Event Horizon they become
super heated and emit massive amounts of radiation we have all seen the famous pictures of the two
black holes taken for the first time in the last few years but these images aren't really of the
black hole itself rather it's a radio image of a matter surrounding the body black hole pitch
black Gap in the center where no light can escape but there are some black holes that do not have
an accretion disk making them more invisible as these Giants move stealthily through space
and astronomers may have just stumbled upon one of these elusive black holes in our own Galaxy
in the past scientists have been able to find some black holes by noting their influences on the
space and objects around them seeing Stars change trajectory or objects suddenly disappear from
view our telltale signs that a black hole may be lurking nearby scientists have seen these types of
disturbances in the center of the Milky Way There is a group of stars with erratic orbits whipping
around the supermassive black hole at the heart of our galaxy in a complex gravitational dance
but this type of detection doesn't work reliably for rogue black holes that may not pass by other
matter very often so this team of astronomers were more focused on detecting a special phenomenon
known as gravitational micro lensing in which an object with a massive gravitational force will
bend the light rays of light as it passes by it this is exactly what the astronomers saw as they
gazed into space by understanding and applying Einstein's theory of general relativity the
researchers were able to analyze the data they retrieved in order to understand what they were
seeing they had found an object quickly flying through the Galaxy that was massive enough to
warp the Rays of light as it passed in front of them they hope that this study would lead to the
development of a new method to search the skies for black holes will this object be confirmed
to be a black hole and become the first one detected solely by its ability to bend light waves
while the astronomers who made this discovery believe that this object is most likely a
black hole there is always the possibility that it could be another Super dense object
a few years ago one team of researchers working with gravitational micro lensing found that only
a small percent of micro lensing seen throughout the Universe are caused by black holes meaning
that there are many other sources that could produce a similar phenomena but when micro
lensing is caused by a black hole there will be certain features that will help astronomers
confirm what they have found the micro lensing detected in June showed a brief flare in the
brightness of a star as the object moved in front of it from our point of view two separate teams
took the data from the optical gravitational lensing experiment telescope and the micro
lensing observations in an astrophysics telescopes in Chile and New Zealand respectively and the
results they produced are somewhat conflicting with the different measures of the object's Mass
one team calculating that it was around two to four solar masses while the other team
found it to be around seven solar masses once more researchers can look at the data and the object is
found to have been two and four solemn masses it is likely too small to be a black hole and
would be most likely categorized as a neutron star but if it is found to be closer to seven
solar masses then the team can be rest assured that the object they found is a black hole what
would it mean for us if we can confirm this type of super elusive black holes do exist
based on recent studies there may be more Rogue black holes flying through our galaxy
than previously believed although Rogue black holes are rare compared to other types of black
holes astronomers do believe that there could be several dozen Rogue black holes stealthily moving
through the Milky Way alone distorting space and devouring any matter that gets in its way
hopefully this method of finding black holes will allow astronomers to more
easily detect this stealthy monsters but if there are more Rogue black holes inside
our own Galaxy do they pose a threat to Earth and the rest of our solar system
the concept of Rogue black holes may seem scary to you but before you start worrying
let's look at what the chances are Earth being in one's path first off the Milky Way
is gigantic compared to the scales that we are used to it stretches for more than 105
000 light years wide and our solar system inhabits a very small Corner taking up
Amiga 280 billion kilometers or roughly 0.03 light years wide not only that but the sum
of the largest black holes are thought to be around the size of our solar system and is in
extremely unlikely that one of that size would end up in this state all of this makes us an
extremely small Target for a black hole to pose any danger to us within this large Galaxy the
odds of a rogue black hole getting close enough to affect us in any way is very close to zero
while astronomers believe it is unlikely for a supermassive black hole to go Rogue and lose its
secretion disk there is still a chance that some unknown event could send supermassive
black holes flying through the universe what would happen if one of these theoretical Giants
came close enough to have an effect on our solar system or Galaxy would anything survive
thanks for watching comment down below and tell us if you think black holes pose
a problem to humanity or if you aren't too worried about them see you next time on Mata
