Could Anti-gravity Really be Possible?

over the decades antigravity has been the stuff of science fiction bova have been many inventions purporting to be anti-gravity devices from gyroscopic lifters to superconducting magnets so far there has been nothing that is truly capable of nullifying shielding or modifying what we know as gravity so could a form of anti-gravity even be possible given our current understanding [Music] [Applause] [Music] just to be clear what I'm referring to when I say anti-gravity is a way to even nullify or modify the effect of gravity that does not rely upon other forces like electromagnetism or some form of thrust for example whether this would be some kind of local effect that creates a negative form of gravity or modifies gravity so its effect is either increased or decreased almost everything so far which has been claimed to be a form of anti-gravity is really just using other known forces though there is a very interesting effect which if verified could be the closest we have come so far and we will look at that later a plane might be called an antigravity machine because it can lift you up and away from the surface of the earth but it's actually using the pressure differential of a wing traveling through the air at speed to create lift a rocket does a similar thing but by burning fuel which expands rapidly creating thrust and pushing it along and we're gonna thrust it can overcome the pull of Earth's gravity but it's nothing more than a chemical reaction in the 1980s and 90s gyroscopic inertial thrusters were seen as potential sources of reaction less thrust when seen in action they appear to be able to generate lift and defy gravity they use various methods of leverage against for support of a large gyroscope or flywheel this appears to generate lift when the angle of the gyroscope is changed but after years of theoretical and laboratory testing by NASA and others no thrust or anti-gravity forces in free space were found to be produced other so-called anti-gravity lifters using the Byfield Braun effect are in fact using the propulsive force of ion flow by charging a very lightweight object or lifter usually with a high positive voltage the surrounding areas iein eyes as the ions are attracted to the opposite negative electrode usually on the ground they interact with neutral air molecules in between creating an airflow with enough force to levitate the lifter while some claim that the effect worked in a vacuum and therefore must be some form of interaction between the electric field and the Earth's gravitational field and implying but it could be used to create an anti-gravity effect when NASA tested it in a vacuum equivalent to that found at low Earth orbit the effect disappeared proving that it was caused by the propulsive force of ions pushing on the air although gravity is one of the fundamental forces and thus anti-gravity would be theoretically impossible it has been proposed that if another force could attract matter or repel it like a theoretical anti-gravity there may be a machine could be made to simulate that effect in scientific papers published between 1991 and 93 American scientist ning lee claimed that anti-gravity effects could be achieved if the ions in a bose-einstein condensate that's a state of matter where all the atoms in it can act like one could be trapped into a high-temperature superconducting disc of a time-varying magnetic field a huge amount of energy could be stored in its lattice structure as each ion would spin rapidly it would create a tiny gravitational field however because all the ions fermi bose-einstein condensate would be aligned together the effect will be magnified by the billions of ions in the disk the theory is that this would create a gravity like field that could either increase or decrease the effect of gravity which ning lee called AC gravity because it could either be attractive or repulsive in nature she said that that experiments in the lab had created a beam like effect above the disc which affected matter for some distance and backed up the theories even though it created a lot of interest at the time in 1997 she published another paper saying that new measurements with a more sensitive gravimeter it's affect to be either very small or non-existent in 2000 Ling Li left the University of Alabama and set up her own company AC gravity LLC and in 2001 was awarded a grant worth just under four hundred and fifty thousand dollars from the Department of Defense to investigate it further since then she has all but disappeared and nothing more has been heard about her research but the company AC gravity LLC is apparently still in business experiments carried out by yevgenii pod cut north in early 1990s using rotating superconducting discs in a magnetic field claimed to decrease the effective gravity by about 2% on objects placed above a disc and again it appeared to act like a beam above the disc for a considerable distance however these results had not been able to be verified by other scientists he claimed that the other researchers had not used the same setup and that's why they couldn't reproduce four results and when NASA was about to complete the experiments they ran out of funding and a research was taken over by the Department of Defense and he was shut out of any further research in the u.s. because of these russian citizenship this and Ning Lee's work is said to have prompted Boeing to investigate the effect of rotating superconductors with project grasped gravity research for advanced space propulsion with potential uses including space launches artificial gravity on spacecraft aircraft propulsion and fuel less electricity generation though others have pointed out that if the effect could be proven and directed into a beam then it would be able to be weaponized creating a steerable artificial gravity force to destabilize missiles planes and satellites since the information has been released boeing has backtracked a bit and said that it was offered for proposal but chose not to fund it with company money but refused to comment if it was a black project on the company books these and other experiments are based on the idea of graph electromagnetism which looks at analogies between Maxwell's equations for electromagnetism and Einstein's equation for a relativistic gravitation basically the premise is but just as a spinning electron creates a magnetic field then a massive spinning object like the earth would create a drag on space-time a bit like when you spin a ball in a viscous fluid like oil although this drag was predicted nearly a hundred years ago I Stein called it frame dragging it's taken the best part of a century to prove if it actually existed with several independent satellite missions which did indeed measure a small but noticeable dragging effect this is important because our current theories of gravity are the mass curves otherwise flat space-time and this deforming of space-time is gravity this is shown quite well with the weighting of rubber sheet experiment which represents the Sun which pulls a sheet down in the center a ball rolling in a straight line follows the curve of the surface and this is like the earth which is traveling in a straight line but is caught in the curve of space-time created by the sun's mass and so long as the Earth's speed is constant it orbits the Sun if a dragging effect is real then it is affecting gravity and a moving object near a massive rotating object would experience acceleration not predicted by Newtonian laws it's been suggested that this is the effect is what might be behind the massive jets of gas which are ejected from quasars and galactic nuclei rotating supermassive black holes at the Centers of galaxies would also create enormous frame dragging effects this is where of a spinning superconducting disk sinning lees and project grasp experiments come in to simulate this frame dragging and the gravitational warping effect but on a very much smaller scale but the elephant in the room is that we still don't know what gravity really is yes we have Newton and Einsteins laws which predict with amazing accuracy the effects of gravity but these theories don't tell us how gravity works or what the mechanism is that makes mass bend space-time all we know is that gravity is a consequence of mass the greater the mass for greater for bending of space time and hence the greater for gravity although gravity works over huge distances on the grand scale of planets stars and galaxies we don't know how it really works on the very small things at distances on the atomic scale because the effect them is so weak and difficult to measure conversely we don't know how it works where gravity is incredibly strong such as in a black hole there are many theories as to how gravity actually works but none have been proven in quantum mechanics there is a prediction that a force carrying particle called a graviton might exist even though we have found no proof of very existence so far but as all the other three fundamental forces a strong nuclear force the weak nuclear force and the electromagnetic force have at least one force carrying particle it's believed there must be one for gravity too if gravity is a true force gravity appears to have a virtually no interaction with any of the other fundamental forces and works on any form of matter even ones which we currently cannot detect namely the still unknown dark matter there is also no known way to shield against it because it's bending space-time which is the underlying fabric of the universe and as such it's not really a force we only feel its effects when we are stopped from moving when we are standing on the ground for example and being pulled by the mass of the earth below if we were free-falling in space above the earth we wouldn't feel effects at all then there are the observations of the physical universe that show that the rate of expansion from the Big Bang is speeding up instead of the expected slowing down under the effects of gravity so either we have a major problem with our theories of gravity or there is something else that he's providing a yet unknown force which is overpowering gravity and pushing the universe apart in all directions which we currently call dark energy and like dark matter we cannot detect directly but can only see the effect it has a bit like gravity itself so given all of this is true anti-gravity or some form of gravity modification a realistic proposition we still don't know if anything has really come from the research by Ning Li and project grasp it's being rather quiet on that front in recent years despite the internet rumors a source at NASA said that the science appeared sound but the difficulty wasn't scaling it up maybe at some point in the future when we have a much better understanding what gravity is and how it really works will we find a way to manipulate it as we want but unless a new breakthrough is announced it still appears to be in the realm of science fiction although we might not have a complete theory of gravity
