"SO HERE'S ANOTHER OBJECT THAT'S MOVING NEARBY," "OUR MASS THAT HAS BENT SPACE-TIME" "AND, AS IT GOES PAST, IT BENDS TOWARDS THE MASSIVE OBJECT." "BUT A NEGATIVE MASS WOULD BE, IN OUR ANALOGY HERE," "SOMETHING LIKE A MOUND, INSTEAD OF A DEPRESSION." "AND THEN YOU RUN INTO PROBLEMS." "¶¶" "Narrator:" "THE PROBLEM, ACCORDING TO EINSTEIN," "IS THAT USING A NEGATIVE MASS WOULD MEAN INVERTING SPACE-TIME," "EFFECTIVELY TURNING THE FABRIC OF THE UNIVERSE INSIDE-OUT." "Johnson:" "AND WHAT YOU END UP WITH IS SOMETHING" "THAT'S CALLED A RUNAWAY PROBLEM." "YOU HAVE PHYSICS THAT IS JUST RUNNING OUT OF CONTROL." "IT'LL ACCELERATE AWAY ARBITRARILY" "WITH ZERO COST OF ENERGY AND, IF THAT WERE REALLY" "HAPPENING ANYWHERE IN THE UNIVERSE," "WE'D SEE IT SPECTACULARLY BECOMING AN UNSTABLE SITUATION." "¶¶" "[ MELANCHOLY TUNE PLAYS ]" "Narrator:" "IF CLIFFORD JOHNSON" "AND OTHER THEORETICAL PHYSICISTS ARE RIGHT," "ANTIGRAVITY PROPULSION WILL REMAIN AN UNWORKABLE DREAM." "IT SEEMS THE LAWS OF PHYSICS SIMPLY DON'T ALLOW IT." "AT LEAST, NOT AS WE UNDERSTAND THOSE LAWS TODAY." "BECAUSE, JUST AS GALILEO GAVE WAY TO NEWTON" "AND NEWTON GAVE WAY TO EINSTEIN, THEORIES DO CHANGE." "[ MUSIC CLIMBS ]" "¶¶" "AND, IN THE MEANTIME, WELL," "THE ENGINEERS GET ON WITH DOING WHAT ENGINEERS DO:" "BUILDING NEW KINDS OF PROPULSION." "TODAY, THAT INCLUDES NASA." "AT THE GLENN RESEARCH LABORATORY IN OHIO," "WORK IS UNDERWAY TO PRODUCE NEW FORMS OF SPACE ENGINES," "ONES THAT REALLY COULD TAKE US WHERE ROCKETS CAN'T:" "BEYOND OUR SOLAR SYSTEM." "WHAT WE HAVE HERE IS A HIGH-POWERED ION THRUSTER" "AND THE WAY IT PRODUCES THRUST ARE" "IONS ARE CREATED INSIDE THIS RING" "AND THEN, WE ESTABLISH ELECTROSTATIC POTENTIAL" "THAT ACCELERATES THESE IONS OUT AND PRODUCES LARGE VELOCITIES." "AND WHAT THAT DOES IS" "IT GIVES US VERY EFFICIENT PRODUCTION OF THRUST." "Narrator:" "THIS IS AN ION THRUSTER UNDER TEST," "POURING OUT A CONSTANT STREAM OF CHARGED PARTICLES." "IT'S LESS POWERFUL THAN A ROCKET, BUT CAPABLE" "OF ACCELERATING A SPACECRAFT ALMOST INDEFINITELY." "THESE SYSTEMS ARE IDEAL FOR IN SPACE, YOU KNOW." "WE OPERATE THEM PURELY IN SPACE BECAUSE IT'S VERY GENTLE." "YOU KNOW, THE THRUST LEVEL IS LOW," "BUT, OVER TIME, YOU CAN DEVELOP MUCH HIGHER VELOCITIES" "THAN YOU CAN WITH CHEMICAL ROCKETS." "¶¶" "Narrator:" "NASA'S FOCUS IS ON SPACE PROPULSION" "BEYOND THE EARTH'S GRAVITATION," "YET THERE IS A PROPULSION CONCEPT" "THAT AIMS TO REVOLUTIONIZE ALL OF AEROSPACE," "RESURRECTED FROM THE DAYS OF PROJECT GREENGLOW." "10 YEARS AGO, PROJECT GREENGLOW ENDED" "AND RON EVANS THOUGHT" "OFFICIALLY GRAVITY RESEARCH HAD ENDED WITH IT." "BUT, TODAY, HE'S BEEN INVITED" "TO WITNESS A UNIQUE GRAVITATIONAL BREAKTHROUGH." "WHEN RON FIRST BEGAN HIS GRAVITY RESEARCH," "IT STARTED WITH A QUESTION:" "COULD GRAVITY BE USED" "TO DETECT AIRCRAFT THAT WERE INVISIBLE TO RADAR?" "IN THE 1980s, OUR COMPLETE INABILITY" "TO WORK WITH GRAVITY MADE IT IMPOSSIBLE," "BUT, TODAY, RON IS MEETING SOMEONE WHO SAYS HE'S DONE IT." "THIS TIME, THERE ARE NO COVERT MEETINGS." "HE'S GOING INSIDE ENGLAND'S MINISTRY OF DEFENCE" "RESEARCH LABORATORY AT PORTON DOWN." "RON, GOOD MORNING." "WELCOME TO DEFENCE SCIENCE AND TECHNOLOGY." "NEIL STANSFIELD HEADS A DEPARTMENT HERE" "THAT LOOKS AT WHAT THEY CALL DISRUPTIVE TECHNOLOGY." "¶¶" "AND THEY'VE TAKEN A POTENTIAL STEP" "ON THE ROAD TO GRAVITY CONTROL USING QUANTUM ENGINEERING." "SO WHAT WE HAVE HERE IS" "OUR QUANTUM GRAVITY GRADIOMETER." "IT'S A SMALL SYSTEM." "AT THE HEART OF THE DEVICE," "WE HAVE A VACUUM CHAMBER." "THE SENSOR USES LASERS TO FREEZE A CLOUD OF ATOMS." "THIS CLOUD RESPONDS TO DISTURBANCES" "IN THE EARTH'S GRAVITATIONAL FIELD" "CAUSED BY A MOVING MASS." "THE ATOMS ARE SENSITIVE ENOUGH" "TO DETECT THE MASS OF MY BODY" "AT A RANGE OF ABOUT 1 METER." "SO YOUR GRAVITATIONAL FIELD IS AFFECTING THIS DEVICE?" "YES." "THIS IS THE FIRST TIME" "RON HAS SEEN ANYONE ACTUALLY USING GRAVITY." "TO ME, THIS IS AMAZING TECHNOLOGY." "GETTING INTO THE QUANTUM, THAT'S REALLY ALLOWING US" "TO DO THINGS THAT" "WERE JUST UNBELIEVABLE 30 YEARS AGO." "YES, SOME PEOPLE USE THE PHRASE" ""THEY BREAK THE LAWS OF PHYSICS."" "I PREFER TO SAY THEY BREAK THE LAWS OF PHYSICS" "AS WE UNDERSTAND THEM TODAY." "A HUNDRED YEARS AGO," "WE DIDN'T UNDERSTAND THE QUANTUM PHYSICS." "THE IDEA OF BEING ABLE TO MEASURE CHANGES" "IN GRAVITY?" "SCIENCE-FICTION." "COULD NEVER HAPPEN." "TODAY, WE CAN." "YES." "¶¶" "AAAAAAAAAAAAAH!" "Narrator:" "RON EVANS'S MISSION TO CONTROL GRAVITY BEGAN HERE," "IN A COLD, WET CORNER OF LANCASHIRE," "WHERE PEOPLE GO TO LIVE THEIR DREAMS," "WHERE NO ONE EVER WORRIED ABOUT THE WORD "IMPOSSIBLE"." "AAAAAH!" "FOR RON EVANS, GRAVITY CONTROL IS JUST SOMETHING" "WE HAVEN'T LEARNED TO DO." "YET." "I'M SURE WE WILL, ONE DAY." "IT'S JUST A MATTER OF TIME." "AAAH!"
