The Alcubierre Warp Field and Anti Matter [2020]

hello guys just a quick shout out to engineered labs today's sponsor they make these really cool acrylic periodic tables and they even have element 115 well not really but they have all known radioactive ones check them out link in the description trouble is to the nearest stars in this century as possible but only if we managed to achieve one of two things a proportion system that is able to burn for long periods of time at a minimum acceleration of 1g or some sort of warp drive just to put this into perspective if we had a ship like in the expence universe we could reach speeds in the millions of kilometers per hour think about this at a 1g of constant acceleration and burning for about nineteen point two hours we could reach Mars at its closest distance to earth or 55 million eight hundred thousand kilometers in just thirty 2.5 hours compared to the current time which is in between six to eight months that's a huge gain just to show you how much this really matters the same acceleration would grant us a trip to Pluto in just seventy three point seven days it took the new Horizons probe nine point five years to get there so Rockets will help us a lot with the exploration of our own solar system and it is a topic that I will be exploring in later videos but what about other stars like Proxima Centauri which is 4.2 light years away well to reach Proxima Centauri at 40 point 14 trillion kilometers away it would take about six hundred eighty three thousand four hundred sixty five days or 1,873 years to be exact but then again taking to account all other problems related to traveling this far let's face it it's just not viable the Alcubierre warp field would help us surpass the speed of light many times which means that if we had a ship that could go 10 times the speed of light it would take only 153 days to get to Proxima Centauri much more reasonable of it but building a warp drive is not an easy task hello everyone subject zero here Miguel Alcubierre is a theoretical physicist famous for the warp field theory in May 1994 he published a paper titled the warp drive hyper fast travel within general relativity however his goal of this paper contrary to popular belief had little to do with warp drives it was to show that a distortion of space-time is indeed possible within the realms of general relativity and therefore we could travel faster than the speed of light his objective was simple he wanted to verify if there was a way to deform space in such a manner that its contraction and expansion would provide movement to a body inside the space-time warp bubble the idea was to form a bubble around the ship and at the same time the inside of the bubble would remain untouched or flat as they say we all know that huge masses can warp space so the idea came from two factors the ability for space to contract like what happens with large concentrations of matter and expand which is what is happening with the universe the only problem with his idea is that the transition from contraction to expansion requires a massive amount of energy mainly focus on what they call exotic matter with negative mass as complex as it may appear to be in this case since normal matter warp space inwards is why we have gravity negative mass would warp space outwards this is the key of his warp field theory to better visualize this think of it as the path of the ship inside a tube in order for the warp field to work it would contract the front of the tube towards the ship bringing some distant point of space-time closer to it and as it approaches the center it slowly transitions to an expansion behind it so space-time moves around the ship and inside the bubble nothing is moving or space-time remains flat since there is no known limit to how space-time can contract or expand in theory anything inside the bubble can travel faster than the speed of light all you need to do is increase the warp field about ten years later NASA picked up on this project and dr. Harold white from Eagle Works stepped in to verify if the amount of energy necessary for the work field to work could be brought down to something more realistic his great insight was to oscillate in between states or from contraction to expansion by using a thoris around the ship he derived his calculation from the Alcubierre metric and described three main functions the warp bubble shaping function york time which is the measure of expansion and contraction of space and energy density this is when we get this chart what he proposed was that to decrease the mass necessary to make this work and have your ship traveling at 10 times the speed of light you could in turn increase the oscillation of the torus using the york time function but that comes at a cost with a mass equivalence of Jupiter you would have the optimal work bubble conformation that would enable a ship to be located inside the bubble without any distortion or any harm to the ship as you increase the oscillation you diminish the total exotic mass requirements up to a point where all you need is about 700 kilograms of exotic matter but the bubble would be so thick pretty much destroying anything inside the bubble that is when the second torus is introduced with two oscillating Tauri the thickness of the warp bubble can be controlled allowing for flat space to exist inside the bubble keeping everything intact even if we managed to make that ship we still have to deal with other external factors like for instance all the trap energy in front of the bubble anything that is on the way of the ship route would get stuck in front of the bubble so when you stop the ship the energy would be released forward with high intensity so one thing to avoid at all time would be to point your ship at the planet or whenever you arrive you'll pretty much destroy the planet then again this is getting more and more complex by the minute and in the same fashion as a queer all dr. white attempted to do here was to bring the war field theory to of the realm of maybe plausible and that is exactly what he achieved one thing almost all scientists discussing this topic agree is that warping space is possible or at least the numbers tells us that is possible nevertheless what is most likely to happen is work field achieving subliminal speeds like 10% of the speed of light that is by far the most plausible scenario for the next 80 years and 10% of the speed of light is a big deal after all to achieve the same speed using rocket technology you would have to burn at 1g of constant acceleration for 35 days think about that what could change everything though is antimatter there is something about antimatter that we don't know and most likely it will take years for us to acquire a definitive answer for it that is how does it react with gravity is it repelled or is it attracted by it like anything else or better yet what kind of gravitational field would large quantities produce the thing is we really don't know but tests at the CERN facility with G bar experiments will give us some clues this decade how antimatter behaves with gravity is still a mystery and so far no experimental direct measure has ever been successfully performed the goal of G bar is to test the Einstein weak equivalence principle which states that the trajectory of a test particle is independent of its composition and internal structure when it is only submitted to gravitational forces this fundamental principle has never been directly tested with antimatter G bar will directly measure the freefall acceleration note a G of neutral anti hydrogen atoms in the terrestrial gravitational field then again it will take years for us to gather enough quantities anyway whatever they will be able to produce this year although helpful will most likely be inconclusive in many aspects but remember what we are looking for is a concentration of mass that will allow us to expend space but if the experiment is successful and antimatter turns out to be repelled by gravity aside from revolutionising everything it could in theory be used as the exotic matter that al Kabeer described or at least open the door to a completely new field of physics alright folks that's it we're done here [Music] Oh [Music]
