You can’t have spontaneous, created momentum without an explicable push, which is why many scientists don’t take the EmDrive seriously. If the EmDrive works, then it invalidates much of what physicists know about the universe. This content is imported from embed-name.
How fast can EmDrive go?
EmDrive: NASA Engineer Says Physics-defying Engine Could Go 99% the Speed of Light.
Does EmDrive exist?
In theory, the microwaves can exert force against the walls of the chamber to produce enough thrust to propel a spacecraft once it’s in space. At this point, however, the EmDrive exists only as a laboratory prototype, and it’s still unclear whether it’s able to produce thrust at all.
What is NASA EmDrive?
The EmDrive is a concept for a thruster for spacecraft, first written about in 2001. It is purported to generate thrust by reflecting microwaves inside the device, in a way that would violate the law of conservation of momentum and other laws of physics.
What is the most advanced propulsion system?
Plasma propulsion engine The most powerful plasma rocket in the world is currently the Variable Specific Impulse Magnetoplasma Rocket (VASIMR), being developed by the Ad Astra Rocket Company in Texas. Ad Astra calculates it could power a spacecraft to Mars in 39 days.
Is a Reactionless drive possible?
The reactionless drive is supposed to be impossible. Until now it has been science fiction. While NASA has tried to measure thrust using their version of an electromagnetic engine even their device requires intricate measuring devices to reach conclusions as to whether it functions.
Is the Mach effect real?
James Woodward Mach Effect Gravity Assist (MEGA) drive propulsion is based on peer-reviewed, technically credible physics. Mach effects are transient variations in the rest masses of objects that simultaneously experience accelerations and internal energy changes.
Is NASA building a warp drive?
According to Popular Mechanics, the NASA warp drive will expend a massive amount of energy that will “warp” (contract and twist) space time behind the spacecraft, which will create a space time “bubble.” This bubble, which will be created around the ship and curved behind it, will theoretically reduce the distance that …
Can an engine run in space?
While it is possible to run an internal combustion engine in the vacuum and cold environment of space, the reality is that it’s just not feasible. The weight of carrying the fuel and oxidant is the main burden, followed by the challenge of replenishing both when off Earth.
Can you create thrust with just electricity?
Electric propulsion technologies generate thrust via electrical energy that may be derived either from a solar source, such as solar photovoltaic arrays, which convert solar radiation to electrical power, or from a nuclear source, such as a space-based fission drive, which splits atomic nuclei to release large amounts …
Is warp bubble real?
Or at least it was science fiction until the world’s first warp bubble was accidentally discovered by DARPA funded researchers, according to the scientists report. It was discovered by the Limitless Space Institute (LS) team led by former NASA warp drive expert Dr. Harold G “Sonny” White.
Can you create thrust without fuel?
It sounds impossible, but scientists at NASA’s Eagleworks Laboratories have been building and testing just such a thing. Called an EmDrive, the physics-defying contraption ostensibly produces thrust simply by bouncing microwaves around inside a closed, cone-shaped cavity, no fuel required.
Is space travel possible without combustion?
Some parts of space travel are already electrified and present advantages over chemical propulsion. Moreover, hydrogen, the fuel for the main engines , can be produced with electricity.
How is thrust possible in space?
As the exhaust gases go in one direction, the rocket goes in the other to keep the total momentum of the system constant. This momentum change of the gases gives the rocket the “push” to go forward. We call this push, the thrust of the rocket, i.e. the force exerted on the rocket.
What would happen if a spaceship ran out of fuel in space?
Even when the thrust that comes from the fuel runs out, the space ship will still move forward thanks to the momentum that came from the fuel. This momentum will then carry the space ship forward on the same trajectory that it was already travelling, even when the fuel runs out and the engine shuts off.
How fast can an antimatter engine go?
Nasa spacecraft are currently powered by ion thrusters, which have top speeds of 200,000mph. The antimatter rocket could hit speeds of 72 million mph, Weed claimed. The long term goal is interstellar travel, but before that there are more practical, lower-orbit applications for Positron Dynamics’ engine.
How fast will rockets go in 2050?
Spacecraft have been stuck at slow chemical rocket speeds for years and weak ion drive for decades. However, speeds over one million miles per hour before 2050 are possible. There are surprising new innovations with technically feasible projects.
Can magnets create propulsion?
A: Electromagnetic propulsion is a new kind of technology which uses a magnet’s natual ability to push another magnet away. When controlled, the magnet’s push can be used to propel another magnetic object. Maglev trains use this technology.
What is the fastest engine for space travel?
The fastest chemical rocket ever, the Star-48 engine was built to launch satellites and was recently incorporated into the New Horizons probe, which took off in 2006. Powered by burning a mixture of ammonium perchlorate and aluminum, it boosted the Pluto-bound probe to approximately 36,000 miles per hour.
Is warp drive Reactionless?
Although the warp motion itself is inertialess, the electromagnetic coupling between the nodes and ship is not, so the warp drive can best be described as reactionless, rather than inertialess.
What is a gravity drive?
Gravity Drives are essentially portable jumpgates, allowing ships equipped with them to open a jump point and cross between real space and hyperspace whenever and wherever they want. More advanced gravity drives can also generate powerful gravity shields and allow ships to travel at incredibly high speeds.
Does interstellar space have gravity?
Here are the key points: There is still gravity in space. Astronauts feel weightless when both they and their spacecraft are accelerated only by gravity. To the astronauts, it feels just like there is no gravity.
What is a Reactionless engine?
Reactionless propulsion, “support-less propulsion”, or “inertial propulsion” are all names of a technological concept of an engine that moves a spacecraft without using any external body to push from, and without jettisoning any of its parts.
Do you age at the speed of light?
Changes to time and distance. Perhaps one of the most famous effects of special relativity is that for a human moving near the speed of light, time slows down. In this scenario, a person moving at near light speed would age more slowly. This effect is called time dilation.
Is warp 1 the speed of light?
Warp one, a veritable snail’s pace in the world of Trek, is equal to the speed of light. Warp speeds exceeding warp one equal a multiple of C (the speed of light), but the exact speeds are variable, depending on the source material. It seems the Federation altered its scale as time went on.
