Why does the EmDrive not work?
No energy is going in or coming out, so how are the waves initialized, how do they continue to move, and where is their momentum coming from? You can’t have spontaneous, created momentum without an explicable push, which is why many scientists don’t take the EmDrive seriously.
How does an EmDrive work?
The design of the EmDrive, copyrighted by its parent company SPR Ltd, works by trapping microwaves in a shaped chamber where their bouncing produces thrust. The chamber is closed, meaning from the outside, it will appear to simply move without any fuel input or any thrust output.
Is the EmDrive real?
The EmDrive Isn’t Dead Yet Says the Guy Who Invented the EmDrive. The inventor of the physics-defying EmDrive defended his controversial propulsion device. Roger Shawyer, who created the EmDrive in 1998, said competing researchers got the whole design wrong, leading to recent failed tests.
Are EM drives possible?
Side stepping that Earth shattering possibility, the EM Drive, through rigorous peer review does indeed work. Not only does it work but because it doesn’t require fuel it’s lighter, cheaper, safer and far more efficient than current space rockets. It also doesn’t explode. It’s also fast.
Why is FTL impossible?
Because the concept of “speed” requires measuring a certain amount of distance traveled in space during a certain period of time, the concept of speed does not even physically exist beyond the speed of light. In fact, the phrase “faster than light” is physically meaningless.
What is an EM Drive and how does it work?
The EM Drive was invented by Roger Shawyer around the turn of the century, and involves a large, tapered metal cylinder that’s closed at both ends. Microwaves are generated inside the cylinder and bounce back and forth. That’s pretty much it, and yet somehow this device actually seems to produce a small amount of thrust.
What is the EmDrive and why is it so controversial?
The EmDrive first drew attention, both credulous and dismissive, when New Scientist wrote about it as an “impossible” drive in 2006. Media outlets were later criticised for misleading claims that a resonant cavity thruster had been “validated by NASA” following White’s first tentative test reports in 2014.
How does the EmDrive violate the conservation of momentum?
Conservation of momentum. The proposed theory for how the EmDrive works violates the conservation of momentum, which states any interaction cannot have a net force; a consequence of the conservation of momentum is Newton’s third law, where for every action there is an equal and opposite reaction.
Does the EM Drive break the laws of Physics?
One of the most controversial stories in science right now is the EM Drive, a hypothetical new type of spacecraft engine that seems to break the laws of physics.
