Physicist: In a word: no. A reactionless drive is basically a closed box with the ability to just start moving, on its own, without touching or exuding anything.
How does a Dean Drive work?
Analysts conclude that the motion seen in Dean’s device demonstrations was likely reliant on asymmetrical frictional resistance between the device and the surface on which the device was set (“stick and slip”), resulting in the device moving in one direction when in operation, driven by the vibrations of the apparatus.
What is a Reactionless engine?
By definition, a reactionless drive or inertia propulsion engine is any form of propulsion not based around the expulsion of fuel or reaction mass. The name “reaction mass” comes from Newton’s Third Law of Motion, usually expressed as, “For every action, there is an equal and opposite reaction.”
What is a non reactionary propulsion system?
A reactionless drive is a hypothetical device producing motion without the exhaust of a propellant. … Reactionless drives are often considered similar to a perpetual motion machine. The name comes from Newton’s third law, often expressed as: “For every action, there is an equal and opposite reaction.”
Is warp drive faster than light?
A spacecraft equipped with a warp drive may travel at speeds greater than that of light by many orders of magnitude. … In contrast to hyperspace, spacecraft at warp velocity would continue to interact with objects in “normal space”.
Can you move in space without a propellant?
A NASA study has recently concluded that the “Cannae Drive,” a disruptive new method of space propulsion, can produce small amounts of thrust without the use of propellant, in apparent discordance with Newton’s third law.
Does the EM drive work?
After failing critical thrust tests, the “impossible” engine has proven to be just that. The “impossible” EmDrive has failed international testing in three new papers. The idea was always far out, but that’s part of how science moves forward.
What is inertial propulsion?
Inertial Propulsion requires no propellant or jets to produce motion. Motion is produced by what Dr. Eric Laithwaite termed Motion-by-Mass-Transfer (MMT) (Horizontal Motion=HMT, Vertical=VMT). … Each rotor moves with Uniform-Circular-Motion (UCM)-no jerking.
Has the EmDrive been debunked?
In March 2021, physicists at the Dresden University of Technology published three papers claiming that all results showing thrust were false positives, explained by outside forces: When power flows into the EmDrive, the engine warms up. … Our measurements refute all EmDrive claims by at least 3 orders of magnitude.
Is NASA working on warp drive?
NASA is obviously still working out the kinks of their warp drive, but perhaps it’s only a matter of time before at least neighboring star systems, like Proxima Centauri, will be in reach for human crews. Until then, we can only look at the furthest stars using our telescopes.
Does the EmDrive work in salvation?
Last night (July 19) in the fictional television show “Salvation” on CBS, where an asteroid is on its way to slam into the Earth in six months, engineers talked about the EmDrive — an experimental engine that is supposed to break the laws of physics. While the plot is fully fictional, the EmDrive is not.
What is the fastest propulsion system?
Laser beam powered lithium-ion drives ten times faster than any previous ion drive. A spacecraft with this system would take less than a year to get to Pluto. JPL is building and proving out the various components of this system.
What is Quantum drive?
A quantum drive is a type of engine that generates a Chan-Eisen field, enabling spacecraft to travel at approximately 20% of the speed of light.
How rocket engines work NASA?
In a rocket engine , fuel and a source of oxygen, called an oxidizer, are mixed and exploded in a combustion chamber. The combustion produces hot exhaust which is passed through a nozzle to accelerate the flow and produce thrust.
How many mph is Warp 1?
If you are referring to Warp Factor 1 from the Star Trek universe, this is equivalent to the speed of light. The speed of light, and hence Warp Factor 1, is roughly 670,616,629 mph.
Why is warp 10 Impossible?
You can’t go faster than warp 10 because it is infinite velocity where you occupy all points in the universe at the same time. In TOS when they did so, it was on the old warp scsle where warp 14 is not warp 9 on the new scale. In Voyager, they discovered a new forn of dilithium that remained stable at transwarp speeds.
Do wormholes in space exist?
Wormholes — shortcuts in space and time — have long been a staple of science fiction. But some scientists believe we may soon be able to prove that they are a real part of the universe—as real as the sun and the stars or you and I.
How does a spaceship propel itself in space?
In space, rockets zoom around with no air to push against. … Rockets and engines in space behave according to Isaac Newton’s third law of motion: Every action produces an equal and opposite reaction. When a rocket shoots fuel out one end, this propels the rocket forward — no air is required.
Do engines work in space?
On Earth, air tends to inhibit the exhaust gases getting out of the engine. This reduces the thrust. However, in space since there is no atmosphere, the exhaust gases can exit much easier and faster, thus increasing the thrust. Therefore, the rocket engine actually works better in space than here on Earth.
Can you turn yourself in space?
If you are stationary in space with nothing around you to push off on, you cannot move yourself by pushing on yourself. But you can twist your body around its center of gravity – you just can’t move your center of gravity. On Earth, we can walk forward because we push on the Earth and it pushes back on us.
Is the EmDrive dead?
The EmDrive Isn’t Dead Yet … Says the Guy Who Invented the EmDrive. … Roger Shawyer, who created the EmDrive in 1998, said competing researchers got the whole design wrong, leading to recent failed tests. Shawyer is currently working on the third-generation EmDrive design.
How fast can an EmDrive go?
EmDrive: NASA Engineer Says Physics-defying Engine Could Go 99% the Speed of Light.
How fast is nuclear pulse propulsion?
velocity of 13,411 km/s, at a distance of 4.5 light years, equivalent to 4.5% of light speed).
Can gyroscopes create lift?
But there is no physical way for a gyroscope to cause lift, or linear thrust. Gyroscopes can only produce torques, not linear forces. They are commonly used to rotate or stabilize spacecraft for example.
How does the Alcubierre drive work?
Objects cannot accelerate to the speed of light within normal spacetime; instead, the Alcubierre drive shifts space around an object so that the object would arrive at its destination more quickly than light would in normal space without breaking any physical laws.
What is anti gravity technology?
“Anti-gravity” is often used to refer to devices that look as if they reverse gravity even though they operate through other means, such as lifters, which fly in the air by moving air with electromagnetic fields.
Is magnetic propulsion real?
The present state of modern technology allows the use of magnetic propulsion systems as orbital microthrusters in the near-to-earth space. The current thrust-to mass ratios of these systems are relatively low. Nevertheless, since they do not require propulsive mass, the vehicle mass is constant.
Are solar sails real?
Since the failed Cosmos 1 mission, solar sails have been successfully built and launched by the Japanese Aerospace Exploration Agency (JAXA) with their IKAROS spacecraft that first demonstrated controlled solar sailing, by NASA with their NanoSail-D spacecraft, and by The Planetary Society with our LightSail 1 …
How does a Hall effect thruster work?
Hall-effect thrusters use a magnetic field to limit the electrons’ axial motion and then use them to ionize propellant, efficiently accelerate the ions to produce thrust, and neutralize the ions in the plume. … Hall thrusters operate on a variety of propellants, the most common being xenon and krypton.
Will Lightspeed ever be possible?
So will it ever be possible for us to travel at light speed? Based on our current understanding of physics and the limits of the natural world, the answer, sadly, is no. … So, light-speed travel and faster-than-light travel are physical impossibilities, especially for anything with mass, such as spacecraft and humans.
Is warp drive faster than hyperdrive?
If this is a Star Trek vs. Star Wars question, then hyperdrive is faster than warp drive. It took a warp drive ship 7 years and a lot of cheating to cross a quarter of the galaxy. Hyperdrive ships routinely cross the entire galaxy in a matter of days.
Is warp speed possible in real life?
Seriously. Humans are one step closer to traveling at faster-than-light speeds. A new paper proposes a fully physically realized model for warp drive.
Is EmDrive real?
The “EmDrive” claims to make the impossible possible: a method of pushing spacecraft around without the need for — well, pushing. No propulsion. … But the EmDrive doesn’t just violate our fundamental understanding of the universe; the experiments that claim to measure an effect haven’t been replicated.
How fast can a human go without dying?
This is a well documented field, and the average maximum survivable g-force is about 16g (157m/s) sustained for 1 minute. However this limit depends on the individual, whether the acceleration is applied to one’s entire body or just individual parts and the time in which the acceleration is endured over.
What fuel do satellites use?
The current standard propellant for satellites is hydrazine-based fuel, which is highly toxic.
Why is hydrogen used in rocket fuel?
Liquid Hydrogen (LH2) Rocket Fuel.
Liquid hydrogen fuel has many benefits, including its low molecular weight and high energy output when burned together with liquid oxygen. … Hydrogen also provides low-density liquid fuel for navigation thrusters in orbit. The main engine of the space shuttle used liquid hydrogen fuel.
How fast can the Orville go?
The drive configuration on the Orville provided the ship with speeds over 10 light-years per hour – more than 87,660 times the speed of light.
Why does the Orville have 3 engines?
A quantum engine in each torus lassoed ships like the Orville. Each engine compressed and expanded space by using a pair of phase inducers, one for compression and one for expansion. Thus, the Orville’s quantum drive consisted of three quantum engines and six phase inducers.
