Narrator: A GROWING NUMBER OF PHYSICISTS ARE REACHING

AN ASTONISHING CONCLUSION --

THAT ARE UNIVERSE IS A HOLOGRAM,

AND OUR TRUE LIVES PLAY OUT ON A FLAT BUBBLE

THAT SURROUNDS SPACE AND TIME.

NOW WE MAY FINALLY BE GLIMPSING THAT NEXT REVOLUTION IN PHYSICS.

Narrator: TODAY, PIONEERING TECHNOLOGY

IS TAKING THESE IDEAS OFF THE BLACKBOARD

AND TESTING THEM IN THE REAL WORLD.

WHAT IF THE HOLOGRAPHIC UNIVERSE HAD, KIND OF, GLITCHES,

AND THOSE GLITCHES COULD BE OUR OBSERVABLES?

Narrator: AS SCIENTISTS PUT

THE WEIRDEST IDEAS IN PHYSICS TO THE TEST...

Greene: THAT WOULD BE ONE OF THE MOST SPECTACULAR DISCOVERIES

THAT OUR SPECIES HAS EVER ACCOMPLISHED.

...THEIR QUEST TAKES THEM TO PLACES THAT BEND REALITY

TO BREAKING POINTS,

PROBING THE FIRST SECONDS OF THE BIG BANG,

AND HUNTING FOR THE GLITCHES

THAT COULD REVEAL WE'RE ALL JUST HOLOGRAMS.

WE'RE ON THE VERGE OF UNLOCKING THE SECRETS

OF THE HOLOGRAPHIC UNIVERSE,

A THEORY THAT COULD CHANGE THE WAY WE PERCEIVE EVERYTHING.

SCIENTISTS AROUND THE WORLD

ARE RACING TO ANSWER AND UNUSUAL QUESTION...

ARE WE LIVING IN A HOLOGRAM?

THE WORLD AROUND US LOOKS AND FEEL REAL,

BUT THE COSMOS COULD BE PLAYING AN ASTONISHING TRICK ON US.

I THINK EVERYONE OUT THERE IS FAMILIAR

WITH THE IDEA OF A HOLOGRAM.

WE EVEN HAVE THEM ON OUR CREDIT CARDS.

AND WHAT YOU CAN SEE WHEN YOU LOOK INTO A HOLOGRAM

IS 3-DIMENSIONAL IMAGE,

SOMETHING THAT SEEMS TO HAVE VOLUME.

BUT A HOLOGRAM ITSELF IS JUST 2-DIMENSIONAL.

IT'S JUST A SHEET OF LITTLE FILM.

Narrator: THE IDEA SOUNDS CRAZY AT FIRST,

BUT AS PHYSICISTS DIG DEEPER

INTO THE MATH THAT DESCRIBES THE COSMOS,

IT IS BEGINNING TO TELL THEM SOMETHING SERIOUSLY STRANGE --

THAT THE UNIVERSE IS NOTHING LIKE WE THINK IT IS.

SO IS IT POSSIBLE THAT WE'VE BEEN FOOLED THIS WHOLE TIME?

Narrator: IF THE UNIVERSE IS A HOLOGRAM,

IT MEANS TRUE REALITY IS 2-DIMENSIONAL,

AND OUR 3-DIMENSIONAL WORLD IS JUST AN ILLUSION.

COULD SUCH A WILD IDEA BE TRUE?

LEGENDARY PHYSICIST LEONARD SUSSKIND

WAS PART OF A GROUP OF THEORISTS

WHO BEGAN TO SUSPECT THERE'S MORE TO OUR UNIVERSE

THAN THE REALITY WE SEE.

THEY WERE TRYING TO SOLVE ONE OF THE GREATEST DILEMMAS

IN THE WORLD OF PHYSICS.

GRAVITY AND QUANTUM MECHANICS

WERE AT EACH OTHER'S THROATS, SO TO SPEAK.

PUTTING THESE IDEAS LIKE THIS TOGETHER

HAS BECOME THE CENTRAL QUESTION OF PHYSICS.

Narrator: THE LAWS OF GRAVITY THAT DESCRIBE

HOW BIG THINGS LIKE PLANETS, MOVE,

SEEM TO CONFLICT WITH THE LAWS OF QUANTUM PHYSICS

THAT DESCRIBE HOW VERY SMALL THINGS, LIKE ELECTRONS, BEHAVE.

LEONARD EXPERIMENTED WITH THE MATH

TO TRY TO MAKE THE TWO THEORIES WORK BETTER TOGETHER.

HE BEGAN TO IMAGINE EVERYTHING IN THE UNIVERSE EXISTING

IN TWO PLACES SIMULTANEOUSLY.

AND WHEN HE DID, ALL THE PROBLEMS

WITH THE MATHEMATICS DISSOLVED AWAY.

I HAD THOUGHT VERY HARD ABOUT THIS PROBLEM

AND EVENTUALLY CAME TO THE CONCLUSION

THAT EVERYTHING IS REALLY STORED

ON THE BOUNDARIES OF THE UNIVERSE

FAR AWAY ON SOME LARGE SPHERE,

FAR FROM WHERE EVERYTHING IS TAKING PLACE.

Narrator: ACCORDING TO LEONARD'S THEORY,

EVERYTHING WE SEE IN THE UNIVERSE,

FROM THE PLANET WE LIVE ON

TO THE STAR THAT BRINGS US WARMTH

AND THE BILLION NEIGHBORING STARS

THAT MAKE UP THE GALAXY THAT WE CALL HOME...

...ARE ALL HIGHLY ELABORATE PROJECTIONS.

EVERYTHING WE PERCEIVE IN THREE DIMENSIONS

COULD ORIGINATE FROM A GIGANTIC BUBBLE

THAT WRAPS AROUND OUR COSMOS,

A BLUEPRINT FOR BUILDING A UNIVERSE

MAPPED OUT IN TWO DIMENSIONS

THAT WE EXPERIENCE AS A 3-DIMENSIONAL HOLOGRAM.

TO THINK THAT OUR 3-D REALITY IS REALLY ARISEN

FROM A 2-D TRUE REALITY, NOW THAT'S REALLY MIND-BLOWING.

Narrator: THE IDEA THAT OUR REALITY

IS HOLOGRAPHIC PROJECTION FROM THE EDGE OF THE UNIVERSE,

LEAVES THE WORLD OF PHYSICS REELING.

MANY PEOPLE THOUGHT WERE NUTS.

I REMEMBER ONE OF MY FRIENDS COMING AND SAYING,

HALF-JOKINGLY, "YOU USED TO BE A GOOD PHYSICIST,

BUT YOU'VE LOST YOUR MARBLES."

Narrator: BUT AS SCIENTISTS AROUND THE WORLD

WORK ON THE MATH OF THIS IDEA, THE NUMBERS BEGIN TO ADD UP.

THE HOLOGRAPHIC PRINCIPLE APPEARS TO BE THE THEORY

THAT MAKES ALL OUR PHYSICS WORK TOGETHER.

WE HAVE MANY DIFFERENT WAYS OF UNDERSTANDING THE UNIVERSE.

AND IT'S GENERALLY ACCEPTED IN SCIENCE

THAT WHAT WE ACCEPT AS BEING TRUE

IS WHAT WE OBSERVE AS BEING TRUE.

BUT SOMETIMES THE MATH IS SO COMPELLING

THAT YOU JUST CAN'T IGNORE IT.

Narrator: SCIENTISTS HAVE LEARNED TO TAKE

EVEN THE MOST UNLIKELY THEORY SERIOUSLY

IF THE MATH STACKS UP.

100 YEARS AGO, EINSTEIN'S THEORY OF RELATIVITY SOUNDED CRAZY.

BUT THE ATOMIC BOMB SHOWED THAT IT WORKS.

TODAY, THE EQUATIONS THAT DESCRIBE THE UNIVERSE

AS A HOLOGRAM ADD UP.

SO SCIENTISTS HAVE TO TAKE THEM SERIOUSLY.

MATHEMATICS GIVES US A SUPERPOWER.

IT CAN ENVISION THE POSSIBILITY THAT OUR ENTIRE EXISTENCE

IS NOTHING MORE THAN A HOLOGRAPHIC SIMULATION.

IT REALLY IS THE ENGINE OF OUR GREATEST ACHIEVEMENTS.

IT REALLY DOES SOUNDS COMPLETELY NUTTY,

BUT OUR UNIVERSE COULD, IN FACT, BE ONE BIG HOLOGRAM.

WE SCIENTISTS HAVE TO FOLLOW THE EVIDENCE

NO MATTER THE CRAZY PLACES THAT IT WILL TAKE US.

THAT'S WHAT IT MEANS TO DO SCIENCE.

Narrator: IS OUR EXISTENCE REALLY BEING PLAYED OUT

IN TWO DIMENSIONS SOMEWHERE ELSE?

AND IF SO, WHY DOES IT FEEL SO REAL TO US?

IN THE CITY OF PROVO, UTAH, PHYSICIST DANIEL SMALLEY

USES A PRACTICAL APPROACH TO INVESTIGATE THIS MYSTERY.

HE BUILDS HOLOGRAMS FROM SCRATCH IN HIS LAB.

THE MAGIC OF A HOLOGRAM IS THAT IT A CONTAINS

A 3-D INFORMATION FOR A VOLUME IN A 2-D SURFACE.

HERE WE SEE THAT THE 2-D PATTERN OF LINES

IS ACTUALLY RECREATING A 3-DIMENSIONAL IMAGE

THAT APPEARS TO BE BEHIND THE PLATE.

Narrator: COULD OUR UNIVERSE BE PLAYING A SIMILAR TRICK,

MANIPULATING LIGHT TO CREATE OUR GALAXIES?

DANIEL THINKS A GLASS HOLOGRAM, LIKE THIS ONE, IS TOO SIMPLE.

IT ONLY WORKS WHEN YOU VIEW IT FROM THE CORRECT ANGLE.

THEIR LIMITATION IS THAT THEY CAN'T GO

BEYOND THESE BOUNDARIES,

THE BOUNDARIES CREATED BY THE PLATE.

IF WE'RE NOT LOOKING DIRECTLY INTO THAT PATTERN OF LINES,

WE'RE NOT GONNA SEE AN IMAGE.

IF OUR UNIVERSE IS A HOLOGRAM LIKE THIS,

THE COSMOS WOULD APPEAR TO FLASH

IN AND OUT OF EXISTENCE AS OUR GALAXY SPINS.

♪

BUT THIS BEHAVIOR HAS NEVER BEEN OBSERVED.

A GLASS HOLOGRAM ISN'T THE ANSWER.

DANIEL IS WORKING ON A NEW GENERATION OF HOLOGRAM

THAT GETS US MUCH CLOSER.

IT MANIPULATES SOLID MATTER INSTEAD OF LIGHT.

Smalley: OUR TEAM HERE HAS BEEN WORKING ON A NEW TYPE

OF 3-DIMENSIONAL DISPLAY

THAT ACTUALLY USES NOT JUST LIGHT

BUT ALSO PHYSICAL, MATERIAL OBJECTS TO CREATE 3-D IMAGES

THAT ENABLE US TO BE ABLE TO SEE THOSE 3-D IMAGES

FROM EVERY DIRECTION.

Narrator: ONE LASER MOVES A PARTICLE OF CELLULOSE

THROUGH SPACE,

AND ANOTHER SHINES COLORFUL LIGHT ONTO IT,

CREATING A PICTURE IN MID-AIR.

AND THEN POINT BY POINT, WE'RE ABLE TO BUILD A 3-D IMAGE.

Narrator: DANIEL'S TEAM CREATES A MINIATURE HOLOGRAM

THAT YOU CAN TOUCH AND CAN BE SEEN FROM ANY ANGLE.

THIS IS A GIANT LEAP CLOSER TO A HOLOGRAM

THAT FEELS LIKE THE REALITY WE SEE AROUND US.

BUT THIS ISN'T CONCRETE PROOF.

THE HOLOGRAPHIC LIGHT SOURCE CAN BE BLOCKED.

LIGHT IS ENTERING THE SYSTEM,

AND IF WE BLOCK THAT DIRECTION WITH OUT HANDS,

OUR UNIVERSE DISAPPEARS.

AND THIS, OF COURSE,

IS NOT HOW WE EXPECT OUR REAL UNIVERSE TO BEHAVE.

SO EVEN THIS TECHNOLOGY IS NOT QUITE PERFECT

FOR BUILDING A MINIATURE UNIVERSE.

Narrator: DANIEL'S HOLOGRAMS ARE A POOR FIT

FOR THE REALITY WE EXPERIENCE.

SO IS IT GAME OVER FOR THE HOLOGRAPHIC PRINCIPLE?

IT'S EXTRAORDINARILY DIFFICULT TO TEST THESE IDEAS.

IT DOESN'T MEAN THAT IT'S IMPOSSIBLE TO TEST THESE IDEAS.

IT JUST MEANS IT IS A GRAND CHALLENGE.

YOU HAVE TO REALIZE THAT

THERE HAVE BEEN MANY TIMES IN OUR HISTORY

WHERE PHYSICS HAS CONFRONTED US

WITH SOMETHING THAT JUST DIDN'T MAKE SENSE.

Narrator: SCIENTISTS DON'T WANT TO GIVE UP

ON THE HOLOGRAPHIC PRINCIPLE EASILY

BECAUSE THE MATH ADDS UP.

BUT IF THIS RADICAL IDEA IS CORRECT,

THERE MUST BE EVIDENCE IN OUR OWN UNIVERSE THAT CONFIRMS IT.

THE HOLOGRAPHIC PRINCIPLE COULD BE A GAME CHANGER

AND SOLVE A REALLY FUNDAMENTAL PROBLEM

IN OUR UNDERSTANDING OF THE COSMOS,

SO THE STAKES ARE REALLY HIGH.

Narrator: THE HUNT IS NOW ON TO FIND CLUES

TO THE HOLOGRAPHIC NATURE OF REALITY.

THE SEARCH TAKES SCIENTISTS INTO THE PHYSICS

OF THE MOST EXTREME OBJECTS IN THE UNIVERSE.

COULD BLACK HOLES PROVE THAT THE UNIVERSE WE LIVE IN

IS A HOLOGRAM?

NOT EVEN LIGHT CAN ESCAPE THEIR CLUTCHES.

BLACK HOLES FASCINATE PHYSICISTS

BECAUSE THE LAWS OF PHYSICS SEEM TO BREAK DOWN INSIDE THEM.

AT NOTTINGHAM UNIVERSITY IN ENGLAND,

SILKE WEINFURTNER INVESTIGATES

HOW BLACK HOLES BEND THE LAWS OF PHYSICS.

I THINK BLACK HOLES ARE THE GUIDE TO NEW PHYSICS.

I SEE THEM AS THIS HUGE OPPORTUNITY.

Narrator: SILKE SIMULATES BLACK HOLES IN THE LAB

BY CREATING POWERFUL VORTICES IN TANKS OF WATER.

YOU CAN THINK OF A BLACK HOLE AT THE EDGE OF THE UNIVERSE,

AND THE QUESTION IS, WHAT HAPPENS

IF YOU COME CLOSE TO THE EDGE,

AND WHAT HAPPENS IF YOU ACTUALLY FALL OVER THE EDGE?

AND WHAT WE TRY TO DO IS TO ATTACK THE PROBLEM

FROM A VERY DIFFERENT ANGLE.

Narrator: IT'S IMPOSSIBLE TO UNDERTAKE EXPERIMENTS

WITH REAL BLACK HOLES,

SO SILKE TURNS THIS WATER TANK INTO THE NEXT BEST THING.

THE VORTEX SPINNING AT THE CENTER OF THE TANK

SIMULATES THE ACTION OF A ROTATING BLACK HOLE.

Weinfurtner: WE HAVE A GIGANTIC TANK

FILLED WITH 2000 LITERS OF WATER,

AND WHAT WE'RE GOING TO DO IS SET UP A BIG VORTEX FLOW.

AND THAT IS SITTING AT THE CENTER OF OUR SETUP.

Narrator: SILKE INTRODUCES FLOATING MATERIAL TO THE TANK.

THE PROJECTED GRID ALLOWS HER TO MEASURE HOW CLOSE MATERIAL

CAN GET TO THE VORTEX BEFORE ITS FATE IS SEALED.

YOU CAN SEE, ANYTHING THAT COMES CLOSER THAN AROUND HERE

SLOWLY STARTS TO GET SUCKED IN.

Narrator: AT A CERTAIN DISTANCE,

THE STRENGTH OF THE VORTEX IS SO GREAT

THAT GETTING SUCKED IN IS INEVITABLE.

IT'S BASICALLY -- IT'S BEING PUSHED

OVER THE EDGE OF OUR UNIVERSE.

Narrator: THIS POINT OF NO RETURN AROUND A BLACK HOLE

IS CALLED AN EVENT HORIZON.

BLACK HOLES ARE INFINITESIMALLY SMALL POINTS IN SPACE,

BUT THERE EVENT HORIZONS CAN STRETCH OUT

OVER MILLIONS OF MILES.

THEY APPEAR AS A BLACK BUBBLE AROUND THE BLACK HOLE.

THIS DARK FRONTIER IS LIKE THE EDGE OF A WATERFALL.

NOTHING CAN COME BACK ONCE IT'S PASSED OVER THE EVENT HORIZON.

BUT WHAT HAPPENS TO OBJECTS INSIDE THE EVENT HORIZON?

AND ARE THEY TRULY PUSHED OFF THE EDGE OF THE UNIVERSE?

Weinfurtner: WELL, THE PROBLEM IS IF YOU THINK OF A BLACK HOLE

THAT SWALLOWS EVERYTHING UP, RIGHT?

AND WHATEVER YOU THROW INTO THAT BLACK HOLE, IT CAN BE A CHAIR,

IT CAN BE A MOBILE PHONE, IT CAN BE FUNDAMENTAL PARTICLES,

WHATEVER YOU GIVE INTO IT, THAT'S BASICALLY LOST.

Narrator: BUT THIS FUNDAMENTAL DESTRUCTIVE PROPERTY

CREATES A HUGE PROBLEM FOR PHYSICISTS.

THIS BEHAVIOR IS INCOMPATIBLE, IN A SENSE,

TO QUANTUM MECHANICS.

Narrator: THE LAWS OF QUANTUM PHYSICS SAY

THAT EVERY PARTICLE OF MATTER IN THE UNIVERSE

CARRIES INFORMATION ABOUT ITS PROPERTIES,

AND THAT THIS INFORMATION CAN NEVER BE LOST.

BLACK HOLES APPEAR TO BREAK THIS ESSENTIAL RULE.

BLACK HOLE, YOU THROW SOMETHING AND THE CONVENTIONAL WISDOM

SAYS IT HAS DISAPPEARED.

BUT IF IT DISAPPEARS, THAT MEANS IT TAKES ALL OF THE INFORMATION

THAT IT CARRIES WITH IT.

WHERE DOES THE INFORMATION GO?

IF YOU LOSE INFORMATION, YOU LOSE THE ABILITY TO PREDICT,

AND IF YOU LOSE THAT, THEN PHYSICS IS IN

A COMPLETELY DIFFERENT PLACE.

Narrator: IT SEEMS LIKE BLACK HOLES AND QUANTUM PHYSICS

CAN'T EXIST TOGETHER IN THE SAME UNIVERSE.

BUT THERE MAY BE ONE WAY TO SOLVE THIS PROBLEM --

THE HOLOGRAPHIC PRINCIPLE.

Narrator: ACCORDING TO ONE VERSION

OF THE HOLOGRAPHIC PRINCIPLE,

BLACK HOLES MAY ACT AS STORAGE DEVICES.

AS AN OBJECT IS SUCKED THROUGH THE EVENT HORIZON,

ITS INFORMATION MIGHT BE STRIPPED FROM ITS PARTICLES

THIS VIRTUAL SNAPSHOT OF INFORMATION

IS HELD AS A PERMANENT RECORD.

IF THIS IS TRUE, NO OBJECT FULLY LEAVES THE UNIVERSE.

INSTEAD, ITS INFORMATION REMAINS IN ARCHIVE FORM,

FLATTENED ONTO THE 2-DIMENSIONAL BUBBLE

THIS HOLOGRAPHIC PRINCIPLE HELPS BLACK HOLES MAKE SENSE

SO, IS IT POSSIBLE THAT WHAT AN EVENT HORIZON REALLY IS

IS SOME TYPE OF 2-DIMENSIONAL MEMBRANE

AND ALL THE INFORMATION ABOUT ANYTHING

THAT'S EVER FALLEN INTO THE BLACK HOLE

THAT OUR UNIVERSE MAY BE HOLOGRAPHIC.

BECAUSE WHEN WE STUDY THE MOTION OF STARS IN ORBITING GALAXIES,

THEY'RE NOT TRAVELLING AT THE RIGHT SPEED.

IT'S THE HOLOGRAPHIC HORIZON THAT PROVIDES THE EXTRA GLUE.

THE TWO DIMENSIONAL GALAXY ON THE HOLOGRAPHIC BUBBLE

PROVIDES A 3-DIMENSIONAL FRAMEWORK

THAT EXTENDS THROUGH OUR UNIVERSE,

LIKE COSMIC PUPPET STRINGS.

THESE HOLOGRAPHIC TETHERS HOLD ON

TO FAST-ROTATING GALAXIES LIKE ANCHORS,

PREVENTING THEIR SPEEDING STARS FROM FLYING OFF

INTO INTERGALACTIC SPACE.

WE'VE BEEN ASSUMING THAT THE UNIVERSE

IS MORE AND MORE STRANGE,

IN FORMS THAT WE CAN'T EVEN REACT TO.

INSTEAD, WE MAY HAVE MISSED THE UNDERLYING NATURE

OF THE HOLOGRAPHIC UNIVERSE.

Narrator: ERIK'S THEORY MIGHT STACK UP ON PAPER,

BUT COULD IT REALLY BE TRUE?

♪

♪

Narrator: THEORETICAL PHYSICIST ERIK VERLINDE'S

HOLOGRAPHIC VISION OF GRAVITY

CHALLENGES OVER 300 YEARS OF SCIENTIFIC THINKING.

AND EXTRAORDINARY CLAIMS REQUIRE EXTRAORDINARY PROOF.

SO, ERIK SEARCHES FOR EVIDENCE.

IN ORDER TO SEE WHAT HAPPENS IN THESE GALAXIES,

YOU NEED TELESCOPES OR OTHER WAYS OF OBSERVING

WHAT THE GRAVITATIONAL FIELD LOOKS LIKE AROUND THE GALAXY.

AND THEN IT'S THE ASTRONOMERS THAT NEED TO TEST THESE IDEAS.

♪

Narrator: ERIK'S THEORIES PREDICT

HOW THE STRENGTH OF GRAVITY VARIES

ACROSS THE DISK OF A GALAXY.

IF THE UNIVERSE IS HOLOGRAPHIC,

THIS VARIATION SHOULD BE OBSERVABLE THROUGH TELESCOPES.

BUT ERIK CAN'T DO IT ALONE.

WE REALLY NEED, LITERALLY, MILLIONS OF BACKGROUND GALAXIES.

YEAH.

Narrator: ASTROPHYSICIST MARGOT BROUWER

SCOURS THE UNIVERSE TO MEASURE THE VARIATION OF GRAVITY

IN DIFFERENT GALAXIES.

ERIK HAS MADE THE PREDICTION HOW THE STRENGTH OF GRAVITY

IN A GALAXY VARIES FROM ITS CENTER,

UP TO VERY LARGE DISTANCES.

SO WE'VE USED THE DATA FROM THESE GALAXIES

TO PUT ERIK VERLINDE'S THEORY TO THE TEST.

Narrator: MEASURING THE GRAVITY ACROSS DISTANT GALAXIES

IS A HUGE CHALLENGE FOR MARGOT.

LUCKILY, THE COSMOS CREATES A WEIRD OPTICAL ILLUSION

TO HELP HER.

SOME GALAXIES ARE SO MASSIVE,

THEY BEND LIGHT AROUND THEM,

AN EFFECT CALLED GRAVITATIONAL LENSING.

THE STRONGER THE GRAVITY,

THE MORE THE BACKGROUND APPEARS TO WARP.

IT'S A PRICELESS TOOL FOR MARGOT'S STUDIES.

YOU NEED A CERTAIN AMOUNT OF GALAXIES

TO GET A SIGNIFICANT SIGNAL. -OKAY.

Narrator: MARGOT NEEDS TO TRAWL VAST AREAS OF THE COSMOS

FOR DATA TO EVALUATE THIS RADICAL IDEA.

TO TEST ERIK VERLINDE'S THEORY

WE STUDIED MORE THAN 33,000 GALAXIES.

♪

Narrator: MARGOT MAPS THE DISTRIBUTION OF GRAVITY

IN THESE GALAXIES BY LOOKING AT HOW THEY DISTORT THE LIGHT

FROM MILLIONS OF GALAXIES BEHIND THEM.

SHE THEN COMPARES THE RESULTS

TO THE PREDICTIONS MADE BY ERIK'S FORMULAS.

INCREDIBLY, ERIK'S THEORY IS AN ALMOST PERFECT FIT

FOR THE UNIVERSE WE SEE AROUND US.

THE SPIRAL GALAXIES THAT HAVE MYSTIFIED ASTRONOMERS

FOR DECADES COULD JUST BE A NATURAL FEATURE

OF THE HOLOGRAPHIC UNIVERSE.

ERIK VERLINDE'S THEORY

GIVES A SLIGHTLY MORE ELEGANT SOLUTION.

BUT WHERE WE HAVE TO ADJUST THE THEORIES OF GRAVITY

TOWARDS THIS-- YEAH, QUITE EXTRAORDINARY.

Narrator: ASTRONOMERS NOW HAVE AN ALTERNATIVE WAY

OF UNDERSTANDING THE COSMOS,

ONE THAT DOESN'T REQUIRE DARK MATTER.

I KNEW, IMMEDIATELY, WHEN I SAW IT,

THAT THIS WAS SOMETHING SIGNIFICANT,

THAT THIS WAS SOMETHING SPECIAL,

AND THAT I WAS THE FIRST ONE TO SEE IT,

AND THAT FELT AMAZING.

Thaller: ISAAC NEWTON USED THE LAWS OF MATHEMATICS

TO WONDERFULLY DESCRIBE HOW OBJECTS ACCELERATE,

HOW PLANETS ORBIT AROUND STARS.

BUT THERE WERE SOME THINGS THAT WEREN'T QUITE RIGHT.

AND THEN HE NEEDED EINSTEIN.

EINSTEIN DIDN'T PROVE NEWTON WRONG.

HE TOOK NEWTON'S IDEAS AND EXPANDED THEM

TO DIFFERENT CIRCUMSTANCES.

HOLOGRAPHIC UNIVERSE NOW TAKES US ONE STEP FURTHER.

SOMETIMES OUR IDEAS ARE FLAT OUT WRONG.

BUT THE AMAZING THING OF THE LAST 100 YEARS

IS THAT WE'VE SEEN THAT MANY OF THESE NUTTY,

CRAZY-SOUNDING IDEAS HAVE BEEN BORNE OUT BY OBSERVATION.

Narrator: MORE EVIDENCE WILL BE NEEDED

BEFORE THE SCIENTIFIC COMMUNITY IS CONVINCED.

BUT WITH GROUND-BREAKING THEORETICAL WORK,

AND INNOVATIVE EXPERIMENTAL TESTS

TAKING PLACE ACROSS THE WORLD,

THE EVIDENCE MIGHT SOON PROVE IF WE ARE LIVING IN A HOLOGRAM.

I AM A GREAT FAN OF THE HOLOGRAPHIC IDEAS,

THE HOLOGRAPHIC PRINCIPLE.

IT NATURALLY EMERGES FROM THE EQUATIONS

THAT WE'VE BEEN STUDYING FOR 30-40 YEARS.

AND IT ALSO FEELS RIGHT.

IT REALLY FEELS LIKE IT CAPTURES THE CURIOUS QUALITY OF GRAVITY

IN A MANNER THAT REALLY BEFITS BOTH THE DATA

AND OUR THEORETICAL PREJUDICES.

SO I THINK THERE'S A VERY, VERY GOOD CHANCE

THAT THE HOLOGRAPHIC PRINCIPLE IS CORRECT.

THE HOLOGRAPHIC UNIVERSE IS AN INTERESTING IDEA.

IT MAY EVEN BE RIGHT. IT MAY NOT. WE DON'T KNOW YET.

WE'RE STILL FIGURING THIS STUFF OUT.

BUT I THINK WHAT IT'S TELLING US IS THAT OUR KNOWLEDGE

OF THE UNIVERSE, RIGHT NOW, IS INCOMPLETE.

WE'RE PRETTY SMART AND WE'VE COME A LONG WAY.

THERE'S STILL A LONG WAY TO GO.

IF, HYPOTHETICALLY, THE HOLOGRAPHIC UNIVERSE

WERE SHOWN TO BE TRUE,

THAT'S SAYING THAT THIS 4-DIMENSIONAL SPACE/TIME

THAT WE LIVE IN ISN'T ACTUALLY REAL,

IT'S MORE OF A SIMULATION.

I CAN'T THINK OF ANY MORE, YOU KNOW,

TRANSFORMATIONAL, LIKE, "WHOA!" MOMENT IN SCIENCE THAN THAT.

♪

Narrator: THE HOLOGRAPHIC THEORY

STILL SITS ON THE FRINGES OF PHYSICS.

BUT IT'S BOLD IDEAS HAVE ALREADY SENT SHOCK WAVES

THROUGH THE WORLD OF SCIENCE.

I DO BELIEVE THAT THE HOLOGRAPHIC PRINCIPLE

HAS COMPLETELY CHANGED THE WAY WE THINK

ABOUT ALMOST ALL FUNDAMENTAL PHYSICS.

ONLY TIME WILL TELL

IF THE HOLOGRAPHIC UNIVERSE IS REAL.

EVERYTHING WE THOUGHT WE KNEW ABOUT THE UNIVERSE.
