KNOW YOUR SPACE AGENCY.
I AM YOUR HOST SCOTT BEDNAR.
, TODAY IS ALL ABOUT BLACK
HOLES THEM IF YOU HAVE QUEEN
QUESTION ABOUT THE MUST TERROUS
COSMIC GY A THEN I HAVE HAVE
GOOD NEWS FOR YOU.
NASA LIVE IS A CHANCE TO SENIOR
QUESTION US TO.
USE THE HASHTAG NASA OUR CAN
LEAVE A QUESTION AND THE COME
MEN BOX WHEREVER ARE WATCHING
OK.
FIG ARE A OFLY.
ARE.
YOU HAVE WONDERED WHAT WOULD
HOLE?
OF THE TELESCOPE THAT FLIES THE
FRIENDLY SKIES.
BE SEATED, FASTEN THE SEAT BELT
AND TAKE NOTE OF THE NEARE
EXIT AS YOU GIVE ATTENTION TO
THE SHORT BLACK HOLE SAFETY
VIDEO.
YOU WANT TO VISIT BLACK HOLE?
PACK YOUR BAGS.
UPDATE THE POWER SOURCE.
YOU ARE READY TO BLAST OFF.
HOWEVER, BEFORE DO YOU THAT, I
ONE PIECE OF ADVICE.
DON'T.
OK.
IF YOU MUST GO, I SUPPOSE YOU
SHOULD AT LEAST KNOW A FEW
THINGS ABOUT BLACK HOLES BEFORE
YOU LEAVE.
NODE KNOW WHO A BLACK HOLE IS?
AMOUNT OF BLACK HOLE IS A
PHYSICAL OBJECT IN SPACE LIKE
EVERYTHING HE IS.
POINT WHERE BRAVE TY AND DENSITY
AND LIGHT CAN FALL INTO THAT AND
SOMETIMES OPENING AROUND IT AND
MAYBE SOME RADIATION.
SO BASICALLY, HERE IS REALLY
BAD.
THEY COME IN TWO SIZES.
DON'T ASK ME WHY.
HE WE'RE NOT SURE NOT SURE.
HOWEVER BLACK HOLE IS NOT A LOT
POPULATED BY UNICORNS AND SPACE.
ABSOLUTELY NOT A GOOD PLACE TO
VACATION.
OK.
SO NEXT YOU NEED NW LO KNOW HOW
TO FIN A BLACK HOLE.
ALTHOUGH TEG OF COURSECALLY THEY
THEY LIKELY WON'T.
THE NEAREST WITHIN IS 3,000
LIGHT-YEARS AWAY.
THERE ARE A COUPLE OF GOOD WAYS
TO FIND THEM.
S, BLACK HOLES TEN TO MESSES
WITH ENVIRONMENT SO YOU CAN
SOMETIMES USE INTERESTING CLUES
SUCH AS BUNCH OF STUFF ORBITING
WHAT PAIRS TO BE NOTHING.
SECOND AS WE MENTIONED BEFORE.
THERE IS STUFF OPENING AROUND US
CAUSE BY WHEN TH GET TO YOU.
SO MU THAT YOU FOUND A BLACK
HOLE AND CLEARLY ARE LISTENING
NOT TO GO.
CONSIDERATION.
BLACK HOMEHOLES ARE SET BACK.
HOWEVER YOU NEED TO KEEP FEW
THING MINE.
HOLE THE CHANCE OF ESCAPE IS
CLOSER YOU GET.
IN A GUY AND NOODLE AND GET
REALLY WIRED.
FIELDSND SPACESHIPS AND
COMPLETELY UNCOMFORTABLE, YOU
SHOULD PROBABLY STAY AWAY.
WELL, THAT SUMS UP BLACK HOLES
AT LEAST BEFORE THINGS START
GETTING REALLY COMPLICATE.
BEFORE YOU GO FOR REAL,
REFORETHE HANDY BROCHURE IN THE
SPACESHIP.
>> WOE, THAT WAS ADORBS.
AM OBSESSED MAYBE OUR ALIEN
FRIEND WILL JOIN US LATER.
OK.
GAIN WHEREVER NOT LITERALLY.
STRINESES BERNARD AND SIBASISH.
ALL RIGHT.
NOT BE COMPLETE ABOUT ASKING
WHAT IS A BRACKNELL.
MASSIVE OBJECT IN THE YA
VERSE.
VOLUMES THAT SPACE TIME AROUND
THIS IS IT WARPED SO MUCH NOT
EVEN LIGHT PHOTONS CAN COME OUT
OF IT?
IS COMPRESS, THE SUN IS
COMPRESSED TO VOLUME, A BLACK
HOLE.
VOLUME, IT WILL BECOME A BLACK
HOLE.
NOT EVEN LIGHT FO TONS CAN COME
OUT OF IT.
>> AS STROH PHYSICALLY, BLACK
HOLE IS USUALLY THE EN POINT OF
THE DEAD STAR AFTER IT USED UP
THE FUEL AND IT GETS
COMPRESSEDDEN TO A TINY TINY
SPACE.
>> SO I UNDERSTAND YOU HAVE A
HELP US BETTER YUN HE STAN.
WE HAVE A LOT TO UP PACK.
DO YOU WANT TO SHOW IT TO YOU.
SURE.
RAILROAD THAT YOU AT HOME CAN
SEN IN YOUR QUESTIONS.
USING THE #ASKNASA.
OR JUST TYPE THEM IN THE COMMENT
BOX WHEREVER ARE WATCHING THIS.
ALL RIGHT.
BERNARD, OVER TO.
IT IS THE WAY WE VISUALIZE HOW
IT WORKS YOU A AYE CONSIDERING
TO EINSTEIN.
OBJECT LIKE STARERS PLANET AND
IT WAS STRONG BECAUSE THEY WERE
QUITE CLOSE TOGETHER AND SO
MASSIVE AND DIRECT INTERACTION.
EINSTEINAYS THAT WAS NTE
RIGHT.
WHAT YOU THO SHOULD THINK IS
CENTRAL REL AND SPACE BEING
UNCHANGING SPACE IS KIND OF
DEFORMABLE AND BIND AND HAVE
EFFECT.
TRAVELING TO SPIS AND NOT NEAR
ANYTHING ELSE AND GO IN A
STRAIGHT LINE THROUGH SPACE.
SOMETHING VERY MASSIVE NEARBY.
SOME DENSE OBJECTS LIKE A BLACK
HOLE, SITTING IN SPACE SORT OF
DOES IT.
OBJECT TRYING TO MOVE IN A
STRAIGHT LINE CAN HOT MOVE IN A
STRAIGHT LINE ANY MOORE 
GOING AS STRAIGHT AS IT
CONDITION AND A CURVE LIKE THAT.
IF THE OBJECT IS LUCKY IT CAN
GET CAUGHT KIN ORBIT DESPITE
HAVING THE ORBIT OR A PATH
CONTINUOUSLY CURVED AROUND THE
CENTRAL OBJECT THAT IN FACT IS
HOW OUR OWN SOLAR SYSTEM WORKS
AND ORBIT AROUND THE SUN BECAUSE
THEY FEEL A SLIGHT CVEVEVEVEVEVT
THE SUN MAKES AROUND IT THAT'S
HOW PRF TY WORKS AND IT HAS
INTERESTING SIDE EFFECTS SO NOT
PLANET AND SMALL OBJECTS BUT
EVEN LIGHT ITSELF CAN BE
AFFECTED 1:00 IF I HAD A VERY
DISTANT OBJECT IN THE UNIVERSE
AND VERY, VERY BRIGHT DISTANT
OBJECT AND I AM TRYING TO LOOK
STRAIGHT OUT AND SOMETHING LIKE
A BLACK HOLE OR THE DENSE OBJECT
IN-BETWEEN THE LIGHT DOESN'T
ABSORBED BUT THE LIGHT THAT
WOULD GO PAST TO ME THOUGH RIGHT
OR THE LEFT  ACTUALLY BIN BACK
TOWARD ME SO INSTEAD OF SEEING
ONE IM MADGE I SEE A FEW OR EVEN
A WHOLE SMEARED OUT WING OF THE
ONE THING AND SOMETHING WE CALL
TATIONAL LENSING.
INSPECT THIS IS SHOWING HOW
BLACK HOLES INTERACT ANDHAT
HOIS WE KNOW THEY EXIST EVEN
THOUGH CAN YOU NOT SEE THEM.
>> THAT IS ONE WAY WE HAVE IT.
ANOTHER WAY KIND OF RELATED IF
INSTEAD OF THE BLACK HOLE BEING
FAR AWAY.
FITS PART OF THE STAR SYSTEM, IT
IS CONTINUOUSES WHICH MAY BE
NORMAL STAR BUT COME BRES
PRESSES  THE BLACK HELD AS
IT ORBIT AROUND.
THE OUTER LAYER CAN BE RIPPED
AWITH AND CAN END UP ORBIT THE
BLACK HOLE ITSELF IN THE DSK OF
GAS AND GAS IS VERY, VERY HOT
ANGLOS BRTLY AND THAT IS ALSOS
>> BUT THANK FOR CLEAR THAT YOU.
A BIT.
BLACK HOLE WAS REVEALED TO THE
WORLD.
SO IBASISH, BERNARD, HOW?
>> NOW WE CAN SEU.
SO THAT IS, THINK, IT IS STEW
PEN DUS ACHIEVE PRESIDENT ON THE
PART OF THE PHYSICISTS SO
ACTUALLY SEE BLACK HOLE SHADOW
SO WHAT YOU SEE IS ACTUALLY THE
DISK IN THE BACKGROUND AND THE
SHADOW OF BLACK HOLE AND IN THE
K SPOT AROUND IT.
SO IT IS THE BLACK HOLE AIN'T IS
CENTRAL ACTIVE ENGINE OF THE
GALAXY AND WHICH IS ELLIPTICAL
WHICH IS NARBY ACTIVE GALAXY
AND ACTIVE AND NOTE IT IT IS NOT
LOOK THE MERCURY FOR EXAMPLE.
MILKY WAS BLACK HOLE AT THE
CENTER BUT IT IS LESS ACTIVITY
SO IT IS NOT AS FAST AS M87 AND
REVERY BRIGHT IN THE CENTER.
IT IS BRIGHT.
BACKDROP OF CENTRA
NOT SUCH INCREDIBLE PHOTO.
FOR NOT IMPRESSED WITH W THE
FIRST PICTURE OF A BLACK HOLE
THEN CLEARLY YOU DON'TUND STARN
THE GRAPH THINK OF SITUATION.
ALL RIGHT.
AS YOU HAVE HEARD EARLIER IN OUR
BLACK HOLE SAFETY FID VIDEO, YOU
STAY FOR AWAY ENOUGH FROM BLACK
HOLES AND THEY ARE NOT THAT
HARMFUL WHICH IS LIGHT OR IS NOT
BEING SKED IN A POOHS
SUPERMASSIVE BLACK HOLE AS WE
SPEAK.
AND IN TECH NY CLOVER OUR OWN
ALIEN TRAVELER.
LITTLE BIT.
WELCOME.
THANK YOU FOR JOINING US TODAY.
SO YOU RECENTLY TAKE TRIP TO A
BLACK HOLE.
DID YOU SEE?
THAT DOWNEDS DANGEROUS.
WHAT DID YOU SEE?
THAT SOUNDS DANGEROUS.
WHAT ARE WE LOOKING AT?
LOOKS LIKE VERY CLOSES INDEED TO
A BLACK HOLE.
KIND OF ACTIVE ONE.
A DISK.
SOME KIND OF JETS COMING OUT TOP
AND BOTTOM SO IT IS MAKING IT
HAPPEN NEARBY.
>> SO TRAVELER   IT DID FEEL
DIFFERENT NEAR A BRACKNELL.
>> MORE PHOTOS.
>> WELL, SO IT HAS BEEN TO A
MILLION DEGREES SO IT MEAN
THAT'S THE BLACK HOLE IS VERY,
VERY VERY HIGH IN THE BLACK HOLE
SO TENS TO HAPPEN THAT SMALLER
BLACK HOLES AND THE BLACK HOMES
SO IT WOULD BE TENSE ARE DENSE
AND THE SUN AND  BLACK HOLES
LIKE SEMINAR.
YEAH.
BLACK HOLES GO.
YES.
WITH HA DOES THAT FEEL LIKE TIME
>> OH.
IT LOOKS LIKE HE WAS TAKING CARE
OF A PLANT BEFORE THE TRIP.
  EGOT BACK AFTER A DAY SORE.
HUGE TREE.
A LOT MORE TIME PAST OUT HERE
FAR FROM THE BLACK HOLE THAN
WHEN HE WAS CLOSE IN.
THE TIME IS ACTUALLY DIFFERENT.
IT TAILSLY DIFFERENT NAR THE
BLACK HOLE.
>> FOR TEN YEARS, THERE WOULD BE
CALLED TO SAVE THOUSANDS OF
YEARS ON OUR CEL AND YOU CAN TA
ACTUALLY LIVE LONGER IF YOU WANT
TO LIVE LONGER.
GO A BLACK HOLE.
>> ALL RIGHT.
TRAVELER THANKS SO MUCH FOR
JOINING.
ABSOLUTELY PLEASURE AND YOU CAN
LOOK FOR LESS DANGEROUS
VACATION.
>> I HAR THE CARIBBEANS NICE
TIME OF YEAR.
YOU AT HOME.
QUESTIONS IN.
THE COMMENT BOX WHEREVER ARE
WATCHING.
WHY IS IT THAT EVEN THE LIGHT
CAN ESCAPE FROM A BLACK MOLE WHY
CANNOT LIGHT ESCAPE FROM A BLACK
HOLE.
TRAVELER EXPERIENCED?
LIGHT TIM ACTUALLY TICKS MORE
SLOWLY AS YOU ARE CLOSE IN TO
THE BLACK HELL AND THE NATURE OF
BLACK HOLE SPACE TIM AND DNOUSLY
GETTING SLOWER AND SLOWER AND
THE EVENT IS RIGHT WHERE IT SLOW
DOWNS A STOP.
QUICKLY AND AS FAR AS ANYONE
DISTANT FROM YOU IN THE SAFE
YOONS HAVE IS CONCERNED YOU ARE
IT IS FROZEN.
SIGNAL YOU CAN PRODUCE GOEY
FURTHER.
COMES TO BLACK HOMES.
>> WELL, OK.
ERIC LAMONT ASKS A DEPICTION OF
BLACK HOLES ACCURATE WITH REGARD
TO HOLLY HOW IT ACTUALLY LOOK
E YES.
AND WE SHOULD REMIND EVERYBODY
THAT I WAS DONE BY NONE OTHER
THAN GIB SO IT HAS TO BE
ACCURATE, OF COURSE.
MAYBE THE BLACK HOLE VIDEOS THAT
WE SEE IN THECREEN.
>> SURE.
ACTUALLY VERY, VERY REALISTIC
IT IN FACT I WROTE A BOOK ABOUT
HOW THEY TOOK PAINS OVER THE
SIGNS TO GET IT WORKING RIGHT
AND WE DO LOVELY PRODUCED VIDEOS
THAT GO INTO A NITE IT AND GIVE
YOU A FLY BY OF THE WHAT IT
LOOKS FLUKE ARE KIND OF GETTING
OR SEEING THIS DISK AROUND A
BLACK HOLE THROUGH DIFFERENT
ANGLES SO NOT JUST ONE ANGLE AND
LOOKING AT JN AND YOU CAN SEE
THE WHOLE THING FLOWING AND AND
THE IMAGES DISTORTED DIFFERENTLY
AS YOU PASS ABOVE AND BELOW THE
PLAIN SO NOW WE'RE KIND OF, WE
ARE FACE ON AND NOW WE'RE KIND
OF GOING DOWN TO EDGE ON AND
FACE ON AGAIN.
IN KREB WE ARE WERE ABLE TO DO
THIS TOGETHER.
COMING UP LATER IN THE SHOW.
YOU AT HOME, KEEP SENG IN THE
QUESTIONS USING THE #ASKNASA.
WE TALKED ABOUT WHAT BLACK HOLES
ARE.
MISCONCEPTIONS ABOUT BLACK HOLES
AND TRUST ME I CANNOT DO THISWIH
I HONESLY DO IS THEY ARE GIANT
VACUUM CLEANERS IN SPACE SUCK
EVERYTHING UP.
THAT IS NOT TRUE.
>> THAT IS NOT RU.
SQUEEZED TO THIS VOLUME, IT
WOULD BECOME A BLACK HOLE.
AND THE AREA OF THIS ONE
COMPARED TO THE ART IS SO SO
SMALL THAT HEAD ON BEINGED INTO
IT.
TO HAVE A GRAVITY AND THE SAME
AS OTHER OBJECTS.
SO WHAT HAPPENS FALLING INTO IT
AND FORM A DISK AROUND IT.
IT GRADUALLY ALSOS MOMENTUM AND
GRAL GRADUALLY FALLS DOESN'T AND
TO GIVE NUMBERS LIKE $1 BILLION.
$1 BILLION BLACK HOLES LIKE THE
SUN.
SAY ONE AM OF THE SUN PER YEAR
SO AGRESION IS CRE CRE SLOW SO
NOTE IT A VACUUM LEAN CLEANER.
WHEN YOU SAY ACCRETION YOU SAY
THE MAT ARE WE ARE SEEING INTO
THE ACTIONS AROUND.
THE SURROUNDED SO THE MATTER
FALLS IN SLOWLY BY USING
MENTUM OF EVERY SPIS AND
TRANSFERRING AND OUTWARD AND IT
GOES GRADUALLY INTO IT AND JUST
FALLS INTO THE BLACK HOLE AND
THE BLACK HOLE MATTER IN CREASES
AND IT CLOSES BUT IT IS VERY,
VERY SLOW.
ENERGY EFFICIENT PROCESS.
>> ALL RIGHT.
STUMBLED IN A BLACK HOLE AND
FELL IN?
OBVIOUSLY THE WAY UNWHICH WOULD
YOU BE DED THAT YOU WOULD BE
STRETCHED.
CLOSE AND ENORMOUS TITLE
FORCESES AND MEANS  THE GRF TIN
DIFFERENT PARS OF THE BODIES
DIFFERENT AND GOING FEET IN.
THEN YOUR FEET ARE GOING TO
APPEAR OR EXPERIENCE GREATER
ASELL RIGS AND STRETCH YOU OUT
LAKE NOODLE.
>> YEAH.
>> NOTHINGING SO SOMETHING YOU
OK.
WHERE WE ARE ANSWERING YOUR
QUESTIONS FROM MOMENT.
LET'S SEE WHAT THE WORLDWIDE
WINS STIRRING UP NOW.
ALL RIGHT.
WE HAVE JUAN ON FACEBOOK ASKING
WHAT WILL BE ON THE OTHER SIDE
OF THE BLACK HOLE?
>> NO.
THAT YOU CAN THINK OF SO WE
DON'T KNOW WHAT IS SIGNED OF A
BLACK HOLE.
>> WE MAY NEVER KNOW.
AND SO OUR UNDERSTAING OF BLACK
HOLES IS A CLASSICAL SERIES.
WE KNOW WE WANT TO ANSWER THESE
QUESTIONS YOU HAVE TO HAVE A
SHEET THAT INVOLVES GENERAL
ACTIVITY, AND KINETIC PUT
TOGETHER AND IF WE GET THAT
PERHAPS WE'LL UNDERSTAND BIT
MORE OF WHAT COULD BE ON THE
OTHER SIDE.
SAYSst SAYING MY
FOUR-YEAR-OLD IS ASKING HAVE WE
SENT ANYTHING INA BLACK HOLE?
>> NO NOT YET.
SOMEHOW THOUSANDS OF LIGHT-YEARS
FROM US.
SO SENDING SOMETHING IS MORE
THAN THAT.
BUT CUE GET DISK OR SOMETHING.
YOU COULD GET FINDS OUT OF IT.
BUT THE SPACECRAFT IS NOT GOING
TO COME BACK AGAIN.
IF IT FALLS IN THEN WE'RE HOT
GETTING.
THOL LOWBY.
>> LET.
BEGIN?
BLACK HOLES WE EN COUNTER KERR
OFTEN ARE IN THE POINT OF A
LIFETIME SO A STAR HASES SPENT
ALL THE ACTIVE LIFE BURNING FUEL
AND GRAVITY PULLING BACK IN.
AND WHEN THE FEEL RUNS OUT.
THE GRAVITY STARTS WINNING THAN
WHOLE THING COLLAPSE AND
LARGE START TO BEGIN WITH AND
COLLAPSE THEN YOU END UP WITH A
BLACK HELL AT IN THE OF IT.
THAT IS HOW BLACK HOLE STARTS.
OK.
STELLAR BLACK HOLE.
HAVING A STAR.
LOTS OF MATTER PULLS INTO ONE
PLACE.
INTO THE GALAXIES TO SO STILL A
BIG BIG QUESTION.
>> AS FOR THE OTHER PART.
HAS IN THE OF ASFAR AS WE KNOW
DON'T END.
BACK HOLES ARE FORMED AND ONLY
CAN GET BARNING ABOUT EA
BIGGER.
GRAVITY WE MAY KNOW HOW THEY
COULD ACTUALLY EVAPORATE AWAY.
THIS IS SOMETHING STEPHEN
HAWKING CAME UP WITH IN THE
PAST.
MAY BE SMALL BLACK HOLES TO
EVAPORATE ANDS DID PAIR BUT WE
HAVE NOT VALID THAT YET.
IT IS STILL NOT.
>> AGAIN.
THE HASHTAG ASK SPACE OR
COMMENDING IN THIS STREET
KNOW ABOUT THEM?
LOTS OF MISSIONS THAT STUDY THEM
ONE OF THEM CALLED SOPHIA IS A
TELESCOPE THAT NIS IN AIRPLANE
AT 30,000 FEET.
COLD AND DISTANT REGIONS OF THE
UNIVERSE INCLUDING MATTER AROUND
BLACK HOLES WHILE SOPHIA CANNOT
DIRECTLY CAN UNCOVER BY STUDYING
MATERIALS AROUND THEM.
>> WE'RE HERE AT THE ARMSTRONG
PALMDALE FACILITY WHICH FLIES
AIRPLANES FORECA
AND BEHIND ME IS SOPHIA IT IS
747 AIRCRAFT AND PUT A TELESCOPE
INSIDE OF.
WE FLY INTO THE STRAT FER ABOUT
MOST OF THE WATER VAB SO WE GET
A CLEAR VIEW OF THE UNIVERSE IN
THE NER AND FAR INFRARED.
THINGS YOU HAVE TO GO INTO SPACE
TO DO OTHERWISE.
SO WE'RE ONLY NOW IN THE FIFTH
YEAR.
D AND FAR RE.
OK.
FLIGHT BUT LET'S GO OUT.
>> HOW WE ARE INSIDE OF THE
OBSERVATORY AND THE MOST
LESCOPE AND WHICH IS WAY IN
THE BACK THERE.
THAT'S WHY THEY ARE ALL FACING
THAT DIRECTION.
TELESCOPE TO MAKE SURE
EVERYTHING IS ALL RIGHT.
LET'S GO UP TO TALK ACTUALLY
TAKE A LOOK AT THE TELESCOPE
THIS IS THE SOPHIA TELESCOPE
ACTUALLY THE BACK SIDE OF THE
TELESCOPE.
REAL TELESCOPE THE MIRROR IS ON
THE OTHER SIDE OF THAT WHITE
BULKHEAD AND ONE OF THENGS THIS
THAT WE REALLY HAVE DEAN REALLY
GOOD JOB WITH ON SOPHIA IS
STUDYING THE RADIATION THAT IS
AROUND OUR BLACK HOLE THAT IS IN
THE CENTER OF THE MILKY WAY AND
4 MILLION BLACK HOLE AND WE
DON'T ACTUALLY STUDY TE BLACK
HOLE AND WE STUDY THE MATERIAL
AROUND THELACK HOL
A BLACK HOLE GOES INTO IT AND
THE LIGHT GUESS IN SO YOU NEVER
CAN SEE THE LIGHT INTO THE BLACK
HOLE.
YOU CAN SEE FALLING TON THE
BLACK HOLE AND WE WILL HAVE
OBSERVED IT WITH FOUR
INSTRUMENTANCE THE BEST PICTURE
OF WHAT IS HAPPENING GOING INTO
OUR MASSIVE BLACK HOLE.
AND INCLUDING MOST RECENTLY,
MEASUREMENTS OF THE MAGNETIC
FIELD THAT IS ASSOCIATED WITH
THE MATERIAL THAT IS FALLING ON
TO THE BLACK HOLE.
AND ONLY DONE WITH SOPHIA.
♪ ♪
♪ ♪
BUT THERE ARE MANY WAYS WE
OBSERVE THE TECHS OF THE
MISSISSIPPI TERROUS OBJECTS.
I AM COME BAGK TO.
OTHER THAN SOPHIA HOW IS MASSES
SA STUDYING.
MISSIONS.
MISSIONS SUCH AS HUBBLE SPACE
TELESCOPE AND DONE A LOT OF WORK
ON THAT PHYSICS OF THE MASSIVE
BLACK HOLES AND THE MASS BLACK
HOMANCE THE WINGS COMING FROM
THAT CUSHION AND HOW TO GIVE
FEEDBACK AND NOT ONLYT MORE
MISSIONS LIKE NEW STARS AND
SWIFT AND HOW NAS SASS MISSIONS
HAVE DONE RAN DOING A GREAT JOB
IN UNDERSTANDING THIS HE NATURE
OF THE BLACK HOLES AND THREE TO
GUFF INFORMATION, TODAY IS THE
15th ANDS HAVE ROU THE NAS
SASS SWIFT MISSION STUDYING BACK
HOLE AND TODAY AND I AM
COMMISSION MEMBER AND IT MAKE
MESS PROUD THAT WE ARE STILL
TRYING TO INVESTIGATE MORE TO
BLACK HOLES.
WELL CONGRATANK YOU.
YEAH.
HOLES TWO DIFFERENT BLACK HOLES
AND GALAXIES MERGE INTO ONE.
THAT IS POSSIBLE.
TIME EXCEPT SLOWLY AND GALAXIES
MERGE EVENTUALLY AND LONG TIME
FROM OUR OWN MILKY WAY A DROP
WITH THE GALAXY AND ANTICIPATE
OF THEM HAS SUPERMASSIVE BLACK
HOLE IN THIS CENTER AND
EVENTUALLY AFTER BILLIONS OF
YEARS THEY END UP IN THE KIND OF
BANARY ORBIT AROUND EACH OTHER
AND W WHEN THAT HAP THEY ARE GOG
TO GRADUALLY CONTRACT AND MERGE
BECAUSEHE WHOLE SYSTEM IS
EMYING GRFATIONAL WAYS AND THES
A JECT.
IT MAY HELP.
OK.
OK.
COULD BE WORKED BY SINGLE OB JEB
AND YOU CAN ACTUALLY CAUSE
LITTLE RIPPLE AND CAUSE OVER
MASSIVE OBJECTS AND ACCELERATED
THROUGH SPACE TIME AND HERE THIS
DEMONSTRATION WE HAVE GOT A TUB
OF YELLOW IS ACTING LIKE SPACE
TIME HERE AND THE LATER SHINING
THROUGH.
DROPPING THIS MASS HERE AND LIKE
A SECOND BLACK HOLE AND THE HOLE
MAKING THE JELLO WOBBLE LIKE
SPACE TIME AND THEN AS IT DOES
THAT.
GETS DEFLECTED AND GETS
DISTORTED AND WE HAVE YOU IN
STREW AM TCOULD DETECT V
VERY SMALL CHANGES AND THAT
TELLS YOU, ABOUT THE PRFTITIONAL
WAYS THAT WENT THROUGH SPACE
TIME.
>> OH.
FASCINATING.
GOV BH LESSON ALL RIGHT GOT BACK
TO THE QUESTIONS ON THE
INTERWEB.
ASKING CAN ANY OLD STAR OR
PLANET BECOME A BLACK HOL
>> A FORMER BLACK HOLE OF
COURSE.
THEN MA CHANGES ACTUALLY TRIED
TO CALL THEM LIKE PURCHASE SHEER
AND WHEN IT IS STAGE LIKE THIS.
AND PRESSURE ON THE DONE INIAL
STAR BUT THE STAR IS MASSIVE
ENOUGH THAT NONE OF THESE FORCES
ACTUALLY CAN HOL THE GRFSAL
EFFECT.
FORMED.
IS ALREADY FORMED SO PLANET
FORMING BLACK HOLES NOT
POSSIBLE.
TO BE INEFENT AND PRODU
FIVE FOOT ON THE BLACK HELL AND
LIKE A STAR.
CENTER IT BECOMES A BLACK HOLE
AND GET A SHOTOUT.
>> GIVE IT.
NUMBER OF BLACK HOLES IN THE
SINGLE GALAXY?
>> NO.
YEAH.
GALAXIES.
AND THERE ARE ALSO LIKE DEPENDS
ON HOW THE GALAXY IS AND GALAXY
AND SO AGAIN, IT COULD BE
ANYTHING.
AND THE BLACK HOLE AND AT THE
HOUSE.
YEAH.
YOU CAN SEE BEHIND.
I THAT IS A LITTLE BIT
GRAVITATIONAL LENS WE TA TALK
ABOUT HER TO GREAT PICTURES AND
THE SECRETION DISK AND YOU SEE
THIS PICTURE AND YOU SEE BEHIND
THE BACK HOLE AT THE SAME TIME.
DISTORT IT AND BEND AROUND IT IS
REALLY WEIRD WARPING SHORE SO
NOT SEEING THE BLACK HOLE AND
SEEING THE BLACK LO IN THE BLACK
DROP.
>> FASCINATING STUFF I, WE COULD
TALK MORE.
JOINING US.
THANKS.
HOLESES?
HOLES TO SEE THAT BEAST.
IF YOU ARE ABSOLUTELY OBSESSED
WITH BLACK HOLE LOOKS ME THEN
LIKELY FOR USES THERE 
OPPORTUNITY TO GET SUCKED IN.
THIS BLACK FRIDAY WHILE YOU ARE
BEING BOTH BY STRANGERS AND
FILING A TODDLER FOR THE LAST
DOOR-BUSTER DEAL CONSIDER THAT
BRATING BLACK HOLE FRIDAY.
P MORE SCIENCEY VERSION OF THE
POST THANKSGIVING HYSTERIA.
JUST FACEBOOK,
TWITTER, INSTAGRAM AND YOU KNOW
HOW IT WORKS TO GET SUCKED INTO
A SMORGASBORD.
UNTIL NEXT TIME, I AM YOUR HOSTS
SCOTT BERNARD THANKS SO MUCH FOR
FOR WATCHING NASA SCIENCE LIVE.
