Does the EmDrive actually work?

In major international tests, the physics-defying EmDrive has failed to produce the amount of thrust proponents were expecting. In fact, in one test at Germany’s Dresden University, it didn’t produce any thrust at all.

How does an electromagnetic drive work?

But the EM Drive works without any fuel or propellants at all. It works by simply bouncing microwave photons back and forth inside a cone-shaped closed metal cavity. That motion causes the ‘pointy end’ of the EM Drive to generate thrust, and propel the drive in the opposite direction.

Is Reactionless drive possible?

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.

Can magnetic propulsion work in space?

Electromagnetic propulsion could take us to the heliopause at a speed unachievable by conventional spacecraft. A new type of spacecraft that lacks any propellant is also being proposed. This type of spacecraft, which would be jolted through space by electromagnets, could take us farther than any of these other methods.

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.

How propulsion works 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.

Can electricity be used for propulsion?

Electric Propulsion (EP) is a class of space propulsion which makes use of electrical power to accelerate a propellant by different possible electrical and/or magnetic means. The use of electrical power enhances the propulsive performances of the EP thrusters compared with conventional chemical thrusters.

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 Quantum drive possible?

Although this concept may be allowed by the currently accepted laws of physics, it remains unproven; implementation would require a negative energy density, and possibly a better understanding of quantum gravity.

What is actually warped by a warp drive?

Physics has scoffed at the idea of a real warp drive because it suggests travel faster than light. However, as the drive’s name suggests, such an engine did not push the spacecraft faster than the speed of light; instead, it merely warped space-time in a way that allowed for using a shortcut.

What propulsion works in space?

Interplanetary vehicles mostly use chemical rockets as well, although a few have used ion thrusters and Hall-effect thrusters (two different types of electric propulsion) to great success.
