The Alcubierre Drive: How It (Theoretically) Works ... How NASA Found a 'Workaround' for the Warp Drive. Is the idea that "Everything is energy" even coherent? So there's an upper limit for you. Warp speed! Tempted to do a little more reading around the subject before I reiterate them. In 1994, physicist Miguel Alcubierre proposed a radical technology that would allow faster than light travel: the warp drive, a hypothetical way to skirt around the universe’s ultimate speed limit by bending the fabric of reality..

Our theoretical description of space is the entire observable universe which extends to 13.8 Billion Lightyears (because the universe is 13.8 Billion Years old) through whichever direction we look at it (and is the same from any point of observation in the universe, since the universe is infinite). The Alcubierre Drive, a representative concept of "warp-drive" engines that could exceed light-speed, is referenced to … His idea is now called the Alcubierre Drive. Take this journey with me from the Office to th Ocean, in beautiful Costa Rica! The biggest car show in the Southeast is set to kick off this fall at the 2021 Summit Racing Equipment Atlanta Motorama presented by American Force Wheels. It was an intriguing idea – even NASA has been researching it at the Eagleworks laboratory – but Alcubierre’s proposal contained problems that … Is it simply (not that this is a "simple" matter...) a function of how much energy we can put into it, or does it have its own theoretical limits? You'll learn how to get back in the driver seat of your mental, physical and spiritual … The energy fields required for the Alcubierre warp drive is primarily required for creating the space-time warp but not in accelerating the space vessel and to create those energy fields, would require a significant amount of exotic matter elements like Tachyons. Alcubierre developed a model (metric) within the domain of general relativity that uses this physics loop hole and has almost all of the desired characteristics of a true interstellar space drive, much like what is routinely depicted in science fiction as a “warp drive”. In the mid 1990s, Miguel Alcubierre developed a theoretical way in which a spacecraft might conceivably travel faster than the speed of light without breaking any of the fundamental laws of physics. Why is an airfoil shaped like a teardrop? 668 views. Physicists’ current understanding of spacetime comes from Albert Einstein’s theory of General Relativity. finding the angle for an isosceles triangle roof. Found insideLawrence M. Krauss boldly goes where Star Trek has gone-and beyond. To learn more, see our tips on writing great answers. Why is net worth a recommended minimum for insurance coverage. The Alcubierre warp drive is one of those concepts. Starship bloopers. There is no theoretical limit to the speed allowed by an Alcubierre drive. I understand (or at least think I do) that the craft does not exceed c within its local space-time "bubble", but I also understand that the contraction/expansion of the surrounding space-time results in the craft "breaking" that speed limit relative to other bodies around it, and I'm interested in knowing what that speed could be -- hence the multiple phrasings of the question, because I'm not entirely sure what the "correct" way to phrase this question is. Why does G# sound right when my melody is in C major? But for a warp drive to generate enough negative energy, you would need a lot of matter. The Alcubierre warp drive is one of those concepts. Proposed by Mexican theoretical physicist Miguel Alcubierre in 1994, the drive would propel a ship at superluminal speeds by creating a bubble of negative energy around it, expanding space (and time) behind the ship while compressing space in front of it. Things happen … For example, warp factor w = 9.9999 is equal to nearly 200,000 c. 3 At that speed you could hypothetically travel right across the galaxy in only six months. Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Harold White's work on the Alcubierre warp drive. The Alcubierre Warp Drive by John G. Cramer. The Alcubierre drive, proposed in 1994 by Miguel Alcubierre, suggests that is is possible for a spaceship to travel faster than the speed of light. The quantum drive array (or simply the quantum drive) was the main propulsion system of Planetary Union spaceships, including the USS Orville, the Krill, and likely many other space-flight capable species. Can we speed up spacecraft to suitable interstellar travel speed using oscillating gravity assists on planets on opposite sides of the solar system? But then if contract a large enough proportion of space I would guess there would be problems with potentially creating a miniature black hole. This deformation moves around, and there are no upper speeds dictated by general relativity. NASA’s Harold White has been working since 2010 … Those numbers should certainly encourage scientists to work on the warp drive project. By clicking “Post Your Answer”, you agree to our terms of service, privacy policy and cookie policy. A discussion of the Cauchy problem for General Relativity is also included in this 1973 book. Alcubierre estimated that a warp drive with a 100-meter bubble would require the mass of the entire visible universe . Alcubierre Warp Drive. • Placing a craft within a space that is moving faster than the speed of light is known as the ‘Alcubierre Drive’. The Alcubierre Drive is the human name for the FTL drives, sometimes also called warp drives. Found inside – Page 1"The Physics of Star Wars reveals the very real-life science behind the fantastical galaxy of Star Wars"--Back cover. If not, then why? The Alcubierre drive, at its core, is just a deformation added on flat spacetime as a bump function (it is everywhere flat except for a compact region of spacetime). The warp drive space-time field is described by what is called the Alcubierre Metric which is defined in the General Relativistic context. Comments are not for answers, please convert this into a post. It does this by moving the space around a craft rather than moving the craft itself. Maximum relative velocity within a warp field bubble approaches the limit of c. A warp field is an inertial reference frame. But “Warp Drive” or any other term for … (We'll ignore the other observers overtaking John from the left who see you exiting your Alcubierre craft, $B$, before you turned it on, $A$.). All Rights Reserved. Found insideThe fourth book in the epic saga of humankind's war of transcendence Humanity had appeared to fend off the Sh'daar assault once and for all, though they never learned why the alien empire was driven to halt Earth's advancement toward ... Instead of beating the speed of light, it might be possible for the Alcubierre warp drive to go around the speed of light by warping space-time, just like in the series ‘Star Trek.’. While superluminal, this is often brought up as an argument why such a drive, even if it were to turn out to be viable and possible to construct, would still provide only limited usefulness for interstellar travel. I've done a bit of research and it seems the current thinking is that even though the physics of an Alcubierre drive don't break relativity they do not work in thermodynamics. March 19, 2021. Early calculations for the creation of a warp bubble resulted in quite a grim figure equivalent to the energy equivalent to the mass of the planet Jupiter (1.9 x 1027 Kg). Describes the origins and evolution of stars and the phenomena of black holes--collapsed stars that create a hole in the universe and where time ceases to exist That being said there might be a way of syncing the thermal load out of the bubble. Is it possible for a planet to heat up its moon to habitable temperatures solely through infrared radiation. John and I agree about spacetime intervals between events, but we disagree about time intervals and space intervals. One question which would arise is what effect will be there inside the bubble where the spaceship and crew be present? If sufficient energy is supplied, the drive can push through space time at theoretically … A warp drive doesn’t move what is inside the bubble. But that is all science-fiction. Bobrick and Martire show that any warp drive must be a shell of material in … The Alcubierre drive (Alcubierre warp drive or Alcubierre metric) is a fascinating idea that would allow a spaceship to travel faster than light which seems to … In 1994 he wrote up a paper showing a high speed interstellar travel method, that could go faster than light and still remain inside the restrictions of General Relativity. Background and objectives Sickle cell disease (SCD) is an inherited anemia that afflicts millions worldwide. An Alcubierre Drive is a theoretical (and I mean very theoretical) device that would enable faster than light travel without specifically breaking relativity. When coordinates are processed, a Quantum Shift Drive-integrated Alcubierre Drive starts to engage, and accelerates the spacecraft to a speed of twice the speed of light to escape the gravity well of a large celestial body. One of the most advanced pieces of technology in Serva, it allows … Alcubierre’s warp drive would use this negative energy to create the spacetime bubble. In the "Alcubierre metric," a … That article mentions "arbitrarily large velocities", which I interpret as meaning there's no theoretical limit -- but that statement's from Alcubierre, so White's modifications (and the apparent source of the 10c claim) may have rendered that obsolete.

The Alcubierre Drive would require negative energy to work, and negative energy probably doesn’t exist — or, at least, it isn’t accounted for by today’s models of physics. 15 min read. 1: Image Showing the Alcubierre Warp Drive. Found insideThis script envisions the future use of the Alcubierre drive to reach the center of the galaxy with a means of traveling faster than the speed of light. Theoretically, the Alcubierre drive does not violate Einstein's special theory of ... In effect the spaceship would traverse the distance at superluminal speeds which would help us greatly in achieving interstellar travel. The concept was first proposed by Mexican physicist Miguel Alcubierre. Since John and I disagree on what your actual speed is, we must also disagree on the parameter that explains it, based only on our perspective based on how we happen to be moving when we observe you. Alcubierre Metric. The Alcubierre drive, Alcubierre warp drive, or Alcubierre metric (referring to metric tensor) is a speculative warp drive idea based on a solution of Einstein's field equations in general relativity as proposed by theoretical physicist Miguel Alcubierre during his PhD study at the University of Wales, Cardiff, by which a spacecraft could achieve apparent faster-than-light travel if a configurable energ… Rather than … This book pulls all of that material together from various sources, updates and revises it, and presents it in a coherent form so that those interested will be able to find everything of relevance all in one place. But for a warp drive to generate enough negative energy, you would need a lot of matter. Found insideFazekas compares the Federation's technology with our own, and provides scientifically accurate accounts of the realms and star charts that the Enterprise uses to explore the solar system, nebulae, and more. An Alcubierre Warp Drive stretches spacetime in a wave causing the fabric of space ahead of a spacecraft to contract and the space behind it to expand. Found inside – Page i"--Frans Pretorius, Princeton University "This book is considered the Bible for everyone in the field of gravitation."--Alberto Vecchio, University of Birmingham The closest I have been able to find is Wikipedia's discussion on how, at $10c$, a wall thickness of less than $10^{-32}$ meters (versus the Planck length $1.6 \times 10^{-35}$ meters) would be required, but it is not clear to me whether or not this would impose an upper speed limit for the Alcubierre drive as there are no comparable calculations quoted for other velocities. Does this change at other percentages? The Alcubierre drive uses a huge amount of energy to make a sort of fold-like pocket dimension. The Alcubierre drive is, of course, still highly speculative. In a paper titled “The Warp Drive: Hyper-fast travel within general relativity” published in science journal Classical and Quantum Gravity in May 1994, physicist Miguel Alcubierre suggested a mechanism for getting an object from one point to another at faster-than-light speeds without running afoul of Einsteinian relativity. Gripping novel of hard science fiction by physicist author recounts discovery of the Twistor Effect, which opens doors into countless alternate universes and draws dangerous attention from industrial spies and corporate killers.
