"Physics of the Future" author Michio Kaku talks about the Apophis asteroid, set to skim by Earth in 2029 and possibly hit in 2036. (5:55)

>> Stephen: WELCOME BACK, EVERYBODY.

MY GUEST TONIGHT IS A THEORETICAL PHYSICIST WHO'S WRITTEN A NEWSWEEK ARTICLE ENTITLED "ASTEROID

APOCOLYPSE." SHOCKING STUFF-- THERE'S STILL A "NEWSWEEK"!

PLEASE WELCOME MICHIO KAKU!

[CHEERS AND APPLAUSE]

THANK YOU FOR COMING BACK.

GOOD TO SEE YOU AGAIN.

>> GLAD TO BE ON IT.

>> Stephen: EVERYBODY KNOWS YOU ARE THE AUTHOR OF THE NATIONAL BEST SELLER THE PHYSICS

OF FUTURE.

YOU ARE THE PROFESSOR OF THEORETICAL FIZZISTS IN NEW YORK.

YOU AWJERRED THE COVER STORY ON "THE NEWSWEEK" LET'S CALL IT MAGAZINE, WILL AFTER THE ROVES

DESTROY THE EARTH.

OKAY.

WHAT ARE THE THEORETICAL PHYSICISTS KNOW ABOUT ACTUAL ASTEROIDS?

>> WELL, WE LOOK AT THE EVIDENCE.

IN 1908 WE HAD A CITY THAT FELL ON SIGH BEERA, WIPED OUT 830 SQUARE MILES OF SIBERIAN REAL ESTATE.

>> Stephen: THE TUNGASTA EVENT.

>> THAT'S RIGHT.

IT COULD HAVE HAPPENED LAST WEEK.

IT SCIMED THE EARTH.

WE DODGED A BULLET AND THEN ANOTHER ASTEROID HIT RUSSIA.

AND IF THAT METEOR WAS DELAYED BY TWO OR THREE SECONDS, IT WOULD HAVE BEEN A GROUND BURST

RATHER THAN AN AIR BURST AND AT 40,000 MILES PER HOUR DO THE MATH IT'S 20 HERO SHEEMA BOMBS.

-- HER -- HIROSHIMA BOMBS.

>> Stephen: I'M HAPPY DO YOU THE MATH.

HOW OFTEN IS THIS HAPPEN SOMETHING IN.

>> WE DIDN'T HAVE LARGE METROPOLISES HUNDREDS OF YEARS AGO, WE HAD FISHING VIL YANLZ

THEY HIT THE EARTH BEFORE.

WE WERE OBLIVIOUS, BLISSFULLY UNAWARE THAT WE HAD NEAR MISSES AND ACTUAL COLLISIONS WITH

OBJECTS ABOUT THE SIZE OF AN APARTMENT BUILDING.

THESE ARE CITY BUSES.

AND THEN WE HAVE A NATION BUSTER WHICH IS GOING TO COME GRAZING PAST THE EARTH AND MAY EVEN HIT

THE EARTH.

THAT'S CALLED THE ASTEROID APOFET.

IT'S TEN TIMES BIGGER THAN THE ASTEROID THAT SCIMED THE EARTH LAST WEEK.

>> Stephen: WHAT DO YOU MEAN MAY HIT?

WHAT IS THE -- DO THE MATH.

[ LAUGHTER ]

WHAT IS THE MATH ON THAT ONE?

>> WELL, FIRST IT'S GOING TO SKIM BY THE EARTH IN 2029 AND IT'S GOING TO GRAZE THE ATMOSPHERE.

THAT'S THE QUESTION MARK.

WE DON'T KNOW HOW MUCH FRICTION IT'S GOING TO ENCOUNTER.

THAT CANNOT BE FACTORED RELYIBLY.

WHEN IT GRAZES THE ATMOSPHERE ON THE SECOND PASS IN 2036 THERE'S A WINDOW OF OPPORTUNITY WHERE

THE THING COULD ACTUALLY HIT THE EARTH EVEN THOUGH IT'S STILL VERY SMALL.

>> Stephen: BECAUSE OF THE FRICTION IT ENCOUNTERS ON 2029.

>> THAT'S RIGHT IN THE SECOND PASS.

>> Stephen: CAN WE LUBRICATE THE EARTH IN SOME WAY SO THERE'S NOT SO MUCH FRICTION?

[CHEERS AND APPLAUSE]

AND JUST DUZ --

[CHEERS AND APPLAUSE]

>> THE RUSSIANS HAVE TAKEN THIS SERIOUSLY.

>> Stephen: OF COURSE, THEY WOULD.

THEY ALMOST GOT TAGGED.

>> THEY SAID WE HAVE TO MAINTAIN SERIOUS PROPALS.

MAYBE IN 2029 --

>> Steve: WHERE DO YOU STAND IN SPACE TO DO THE NUDGING?

>> FIRST YOU HAVE TO LAND ON IT, PUT A ROCKET ON IT AND THE ROCKET WILL PUSH IT SLIGHTLY OUT

OF THE WAY SO IN THE SECOND PASS IT WILL MISS THE EARTH.

>> Stephen: I ASSUME THIS IS LIKE BRUCE WILLIS AND A TEAM OF MINERS WHO GET TRAINED TO BE

ASTRONAUTS FOR SOME REASON.

>> PRESIDENT OBAMA HAS STATED THAT THE NEXT GOAL NOW THAT HE CANCELED THE MOON AND MARS

MISSION IS TO LAND ON AN ASTEROID, IN WHICH CASE IF WE LAND ON ONE, IT WILL BE A DRESS REHEARSAL.

BLOWING IT UP ALA BRUCE WILLIS THERE'S BABY ASTEROIDS COMING AT YOU.

>> Stephen: IT TURNS A BULLET SHOTGUN PELLETS.

>> YES, UP WANT TO KEEP IT IN TAFNLGT WE'RE GOING TO BE LOOKING AT IT VERY CAREFULLY TO

SEE THE STRUCTURAL INTEGRITY F.

IT'S HELD TOGETHER BY GRAVEITY OR A SOLID PIECE OF ROCK THAT WE COULD PUSH WITH A HYDRO AGAIN

BOMB OR A ROCKET.

>> Stephen: THE COMET IS COMING BY?

>> PERHAPS THE END OF THIS YEAR THE COMET OF THE CENTURY WILL COME BY.

THEY ARE RARER THAN METEORS.

SHOOTING STARS --

>> Stephen: THOSE ARE METEORS.

>> HOWEVER ATOMIC CAN LINGER IN THE NIGHT SKY FOR WEEKS AT A TIME SCARING THE PANLTS OFF

EVERYONE AND THAT'S WHY EVERYONE THINKS THE KINGS IS FORETOLD BY THE COMING OF COMET AND THE

COMET OF CENTURY IS.

COG LATER THIS YEAR IN NOVEMBER.

>> Stephen: DO YOU KNOW WHAT IT'S CALLED?

>> NO, I HAVE TO LOOK IT UP ON THE INTERNET.

>> Stephen: WE CAN LOOK IT UP RIGHT HERE.

THANK YOU SO MUCH FOR JOINING ME.
