Brian Greene Explains The Most Powerful Explosions In The Universe

, , 100 Comments


>>Stephen: WELCOME BACK,
EVERYBODY. MY NEXT GUEST IS A PROFESSOR OF
PHYSICS AND MATHEMATICS AT COLUMBIA UNIVERSITY. HE’S ALSO THE FOUNDER OF THE
WORLD SCIENCE FESTIVAL, HAPPENING NEXT WEEK RIGHT HERE
IN NEW YORK CITY. PLEASE WELCOME BRIAN GREENE. ♪ ♪ ♪
( APPLAUSE ) WELCOME BACK. COME ON UP. BRIAN, IT’S ALWAYS FUN TO TALK
TO YOU. LAST TIME YOU WERE HERE YOU WERE
TALKING ABOUT GRAVITATIONAL WAVES, THE DISCOVERY FINALLY OF
THE BENDING OF SPAIRKS THE FABRIC OF SPACE TIME. AND WHAT ARE WE EXCITED ABOUT
SCIENCE-WISE TONIGHT? WHAT ARE YOU EXPLAINING?>>TONIGHT, WE ARE BASICALLY THE
ONE-YEAR ANNIVERSARY OF AN AMAZING DISCOVERY IN ASTRONOMY,
THE MOST POWERFUL EXPLODING STAR, THE MOST POWERFUL
SUPERNOVA EVER DETECTED IN HUMAN HISTORY.>>Stephen: WHAT IS A SUPER
NOVA, FIRST OF ALL?>>A SUPERNOVA IS AN EXPLODING
STAR. AND THE ONE THAT WAS FOUND IS
570 BILLION TIMES BRIGHTER THAN THE SUN AT ITS PEAK LUMINOS ET. JUST IMAGINE THAT. A POINT OF LIGHT IN THE SKY HALF
A BILLION TIMES– YOU KNOW, 500 BILLION TIMES MORE POWERFUL THAN
THE SUN.>>Stephen: OKAY, AND WHEN DID
THIS HAPPEN?>>WELL, IT HAPPENED 3.8
BILLION YEARS AGO. BUT IT WAS DISCOVERED ONE YEAR
AGO. IT’S FUNNY HOW IT WORKS, TIME–
>>Stephen: IT IS, IT IS, IT IS, BECAUSE IT’S 3.8 BILLION
LIGHTYEARS AWAY.>>EXACTLY.>>Stephen: DO WE SEE A FLASH
OF LIGHT? IF IT’S THAT BRIGHT WHY DON’T I
LOOK UP AT NIGHT AND SEE THE SKY COMPLETELY BLOTTED OUT BY A
SUPERNOVA?>>IF IT WAS CLOSE ENOUGH TO US,
YOU WOULD HAVE. IN FACT, IF THIS SUPERNOVA
HAPPENS, SAY, AT THE DISTANCE OF PLUTO, IT WOULD HAVE WIPED
EVERYTHING OUT. WE WOULD ALL BE GONE. SO IT’S CEEND OF GOOD THAT IT
HAPPENED 3.8 BILLION LIGHTYEARS AWAY.>>Stephen: SURE, SURE. WHY WAS IT SO HUGE? WHY THIS– WHAT’S THE NAME,
HYPERNOVA.>>HYPERNOVA.>>Stephen: WHAT CAUSES ONE?>>LET’S LOOK AT A STAR BEFORE
IT EXPLODES TO GET A SENSE– YOU CAN BRING IT UP ON THE SCREEN
HERE. IF WE DIVE INTO A STAR RIGHT, WE
PENETRATE, SAY, INTO THE SURFACE, AND WE GO DEEPER, LAYER
BY LAYER, ULTIMATELY WE GET TO THE STAR’S CORE. AND THE CORE, BECAUSE OF ITS
ENORMOUS TEMPERATURE, TENS OF MILLIONS OF DEGREES, IS ACTUALLY
A NUCLEAR FURNACE, WHERE SIMPLE ATOMS FUSE TOGETHER TO BUILD THE
MORE COMPLICATED ONES, LIKE ONES NEEDED FOR LIFE. THE THING SAS THESE ATOMS FUSE,
THEY GIVE OFF ENERGY, AND THAT ENERGY STREAMED OUTWARD AND IT
PROMS THE STAR UP. THAT’S HOW THE STAR SUPPORTS ITS
OWN WEIGHT. AND THIS IS VITAL BECAUSE SOONER
OR LATER, A STAR USES UP ALL ITS NUCLEAR FUEL. NO MORE FUSION, NO MORE OUTWARD
FLOWING ENERGY. AND THEN, OF COURSE, WHAT
HAPPENS IS THE STAR WILL COLLAPSE IN ON ITSELF. MATTER RUSHES IN AND REBOUNDS
LIKE A BALL BOUNCING OFF A VERY STIFF SURFACE, SENDS A SHOCK
WAVE GOING THROUGH THE STAR, RIPPLES OUTWARD LAYER BY LAYER. AND THE STAR EXPLODES.>>Stephen: TOW IS COLLAPSES
IN AND THEN BURSTS BACK OUT WITH THE FORCE OF REBOUND.>>EXACTLY. AND IT’S AN INCREDIBLY POWERFUL
DISPLOAGZ. WE DO HAVE A DEMONSTRATION TO
GIVE A SENSE OF HOW THE ENERGY OF THE CORE IS TRANSMETTED LAYER
BY LAYER THROUGH THE STARS.>>Stephen: WHAT IS THIS
CALLED?>>THIS IS CALLED THE GAL LAYAN
CANNON.>>Stephen: DID GALILEO COME
UP WITH THIS?>>I DON’T THINK SO. BUT HE DROPPED A LOT OF STUFF,
AND WE’RE GOING TO CROP SOME STUFF HERE. THE IDEA HERE IS THAT EACH OF
THESE BALLS REPRESENTS A LAYER OF A STAR. SO THIS BIG ONE HERE IS THE
CORE, AND WHAT WE’RE GOING TO DO IS WE’RE GOING TO DROP THIS
STACK, AND THIS BALL BOUNCING OFF THE BASE HERE IS LIKE THE
CORE REBOUNDING AFTER THE STAR COLLAPSES.>>Stephen: OKAY.>>AND THEN AFTER IT BOUNCES UP,
IT’S GOING TO HET THE NEXT LAYER, WHICH IS GOING TO
TRANSMIT THAT ENERGY LAYER BY LAYER UNTIL WE GET TO THIS
LITTLE GUY OVER HERE. AND WE’LL SEE HOW ALL THE ENERGY
WILL BE CONCENTRATED IN THIS YELLOW BALL, AND WILL FLY UP
WITH –>>THIS REPRESENTS THE OUTER
LAYER OF THE STAR?>>THIS IS LIKE THE SURFACE OF
THE STAR. IF I JUST DROP THIS BY ITSELF,
NOT MUCH HAPPENS. BUT IF I DROP THE WHOLE STACK —
>>OKAY, BEFORE YOU DO THAT, BEFORE YOU DO, THAT I’VE BEEN
INFORMED THAT THIS GALILEOAN CANNON, THIS IS SOMETHING PEOPLE
HAVE DONE BEFORE BUT NO ONE HAS DONE A GALILEOAN CANNON THIS
TALL BEFORE AND WE HAVE SOMEONE HERE FROM THE GUINNESS RECORDS
PEOPLE RIGHT IN THE FRONT ROW. AND YOU’RE GOING TO DROP THE
TALLEST GALILEOAN CANNON OF ALL TIME, AND WE’LL KNOW YOU’VE
BROKEN THE RECORD IF THAT YELLOW BALL GOES THROUGH MY MOUTH UP
THERE.>>THAT’S RIGHT. ( LAUGHTER )
( APPLAUSE ).>>Stephen: OKAY?>>THAT’S OUR TARGET.>>Stephen: THAT’S OUR TARGET. ALL RIGHT, AND THIS– OKAY, SO,
LADIES AND GENTLEMEN, NOW, REPRESENTING A SUPERNOVA AND THE
RAPID EXPANSION OF THE OUTER SHELL OF A STAR AND BREAKING A
WORLD RECORD, MR. BRIAN GREEN. WOOOO! ( APPLAUSE )
>>Stephen: THE WORLD RECORD GALILEOAN CANNON, HYPERNOVEMBER. THE “WORLD SCIENCE FESTIVAL” IS
JUNE 1-5 IN NEW JUNE 1-5 IN NEW YORK CITY. TICKETS AVAILABLE AT

    When you have extreme twist or spin you get light. Gravitation waves the smallest twist. Ratio one in a million points of view.

    Stephen is awesome but his views on organized religion and God in particular are his own. I am glad he doesnt press them and he is willing to hear from others even though science is unintentionally disproving his own ideologies. For this I give Stephen the utmost respect.
    Take a lesson thiests, diests, and the likes. This is how you hold your beliefs without preventing others from learning the truth. Your cognitive dissonance and confirmation bias is your own and kids shouldnt be indoctrinated into God. Just like sex people should be a certain age until they are allowed to praise the lord.
    Parents dont own kids they are guardians and they have absolutly no right to legally brainwashing them with a self contradicting unproven book that actually seems to have more proof pointing towards it being fake.
    I blame organized religion for the level of cognitive dissonance we see in 38 percent of the country right now. Leave God out of schools, textbooks, and govt. and tax the churches until God shows himself to the IRS and the rest of us.

    Not a nerd but fussion energy is when you like fusion 2 helium atoms together and you will get carbon and btw if gravity and radiation if they aren't stable then the sun will emplode emplode is the oppisite of exsplosion.

    Can Brian break a world record by being the man to watch the brightest supernova man has ever seen and test out a welders mask on its ability to block out light and give a review on it

    When a scientist visits ‘Jimmy Fallen’, he says two words and Jimmy his mind blow and makes a joke of it…

    I’m glad to see there are actually intellectual talkshowhosts, in contrast to ‘dumbass’ Jimmy Fallen

    Notice how quiet the audience was when he was explaining everything? That’s because PEOPLE LOVE SCIENCE!! We’re all born curious, so this satisfies that thirst for knowledge of how things work.

    "This is called the Galilean cannon"
    "Did Galileo come up with it?"
    "Idk but he dropped a lot of stuff and we're gonna drop some stuff"
    One of the many reasons I love physics.

    I didn't realize as a kid when I would drop a basketball with a baseball balanced on top, I was actually performing the galilean cannon experiment. I just thought it was cool until the baseball hit me in the face.

    We live in a world of old economic drivers gone stale three times over. The illusion hiding the minions of the rich is gross and overstated and few are conceding to provide stability to the lower classes. The hidden persuaders are still the same old ice cubes and women and many have gone crazy from the illusion thinking they will exceed their class. Most of the rich who do provide anything provide soft exterminations like the churches and wise men of old times. The only solution is a vast rejection of the tools of the illusion, which is impossible. Hilarious?

    A light year is not a measurement of time but distance. The speed of light is not constant. The speed of light depends on the type of medium that it travels through. Lujan Wang accelerated the speed of light by 300x. Other physicists have slowed light to a bicycle ride.
    No one knows the medium that light traveled through in the beginning when the universe violently expanded and was densely packed. Now it has much empty space. Things have changed since that expansion. So don't preach billions of years.
