>> YOU NEED SOMETHING TO BLOW YOUR MIND, TAKE YOUR MIND OFF

>> Stephen: SOMETHING ABOUT THE UNIVERSE, SOMETHING THAT YOU
JUST FOUND OUT.
>> A BILLION YEARS AGO AGO TWO BLACK HOLES COLLIDED.
THEY RELEASED AS MUCH ENERGY IN A TENTH OF A SECOND AS 10 TIMES
ALL THE ENERGY RADIATED BY ALL THE STARS IN THE UNIVERSE AT
THAT TIME.
THAT CREATED A RIPPLE THROUGH THE FABRIC OF SPACE AND TIME,
MOVING AT THE SPEED OF LIGHT, A GRAVITATIONAL WAVE.
THERE IT WAS, A BILLION YEARS AGO ON EARTH, OUR LIFE ANCESTORS
WERE SINGLE-CELLED ORGANISMS, TRYING TO EVOLVE INTO SOMETHING
MORE AMBITIOUS THAN MICROORGANISMS.
A HALF A BILLION YEARS AGO, THE CAM BRIAN EXPLOSION OF LIFE,
LIFE GOT INTERESTING.
IT DEVELOPED LIMB LIMBS, EYES, L MOTION.
AFTER THAT, FAST FORWARD, WE HAVE THE DINOSAURS.
BY THE WAY, THIS RIPPLE THROUGH THE FABRIC OF SPACE AND TIME IS
STILL MOVING THROUGH SPACE AT THE SPEED OF LIGHT.
65 MILLION YEARS ANOTHER THE GIANT LIZARDS WE CALL DINOSAURS
WENT AND I THINK WHEN THE ASTEROID HIT, AND THE MAMALIAN
ANCESTORS, CAN CAN NOW RISE UP AND OCCUPY THIS NICHE, FRESHLY
PRIED OPEN BY THIS ASTEROID.
SO THIS MAMMAL BRANCH WOULD CREATE A SUBSET OF ITSELF KNOWN
AS PRIMATES.
AND AMONG THOSE PRIMATES BECAME-- SOME OF THEM BECAME
HUMAN.
AND IN THE COMMUNITY OF HUMANS, WE DEVELOPED BIG BRAINS,
CAPACITY TO COMMUNICATE, CIVILIZATION, AND WE BIRTHED
SOMEONE CALLED ALBERT EINSTEIN.
AND IN 1916, HE ADVANCED THE GENERAL THEORY OF RELATIVITY,
PREDICTING THE EXISTENCE OF THESE GRAVITY WAVES.
AT THAT POINT, THAT GRAVITY WAVE WAS 100 LIGHT-YEARS FROM EARTH
AND STILL HEADED OUR WAY.
100 YEARS LATER, LAST YEAR, AT THE END OF LAST YEAR, THAT WAVE
WASHED OVER THE EARTH, JUST WHEN WE WERE ABLE TO TURN ON
DETECTORS TO NOTICE THAT THAT WOULD HAPPEN IN THE FIRST PLACE.
AND WE USED LASERS TO DO SO, THAT WERE FIRST PREDICTED BY
EINSTEIN BACK IN-- ( LAUGHTER ).
>> Stephen: 19... 16.
>> EINSTEIN LAID DOWN THE EQUATIONS FOR THE DEVELOPMENT OF
THE LASER, AND 100 YEARS LATER, WE DISCOVER GRAVITATIONAL WAVES
USING LASERS.
AND SO -- >> NEIL, NEIL?
I JUST HAVE TO STOP YOU FOR A SECOND.
BECAUSE I WANT TO POINT OUT ABOUT 30 SECONDS AGO, I THINK
YOU BLEW YOUR OWN MIND THERE.
( LAUGHTER ) ( APPLAUSE )
I'M SORRY.
I GOTTA-- I GOTTA CALL SELF-MIND BLOWN.
WE'VE GOT TO GO BECAUSE WE'RE LIVE.
BUT THANK YOU SO MUCH FOR BEING HERE.
>> THANK YOU "STAR TALK" THE SHOW IS ON
NATIONAL GEOGRAPHIC, AND "STAR TALK" THE BOOK IS IN STORES.
WELCOME TO THE YMPS.
NEIL DEGRASSE TYSON, EVERYBODY!
WE'LL BE RIGHT BACK WITH TRUMPH THE INSULT COMIC DOG.
