An Update on Gravity Drives
Fountainhead News: Apr 27, 2017
About 6 months ago, we published an analysis of cutting edge components that could help propel us reach interstellar space. More specifically, Quantum Computers, Biologic Intelligence, Gravity Drives, and Skutterudites.
In one section, we posited something a few folks have talked about, called a Gravity Drive:
There is a more formal definition for something like this. It’s called an Alcubierre Drive. In it’s most basic terms, it shifts spacetime around the craft thereby allowing it to “travel” faster than the speed of light because it’s not actually traveling, but is a bit more like a skipping stone on top of the water instead of traveling through it.
Since then, there has been a weird paper making its way through the space-based scientific community that offers a real approach to a new type of space travel. It talks about an “impossible” form of propulsion that now, has been proven by other researchers.
The basic concept is it produces thrust without pushing something out the other side. That, ladies and gentleman, is some wacky witchcraft.
You remember back to high school physics, right? Every action has an equal and opposite reaction? Push on this thing in space, and it will send you in one direction while pushing that thing in another direction. The directional forces can be added together and shown that no energy is lost.
We only borrow energy, right.
But this new thing, called an Electromagnetic (EM) Drive, could theoretically get us to Mars in just a hair over 2 months, much faster than the 6 to 8 months typically quoted with current propulsion methods.
The weird thing about this is nobody is entirely certain quite how the new system works. The proposal is an off-shoot of something called the Pilot Wave Theory. It takes us all the way down to Quantum Mechanics.
The debate here is whether a particle has a determined place in space before you observe it. For example, once you look inside the box, you know right where something is. But before you open the box, the object could be anywhere inside it. Schrödinger’s Cat could be dead or alive before you observe it and know for sure.
What this new theory states is that every particle actually does have a precise place in space. That means other strange stuff happens but starts adding more and more complexity which is why people don’t quite believe that’s the right approach.
Only time will tell as we move this EM Drive into space and test it there in zero gravity in a vacuum. Until then, the universe just keeps getting stranger and stranger.
Here’s to the crazy ones?
P.S. If light is a wave and a particle, then could that particle just be carried along upon a wave across the universe? Much like a string of pearls that you whip up and down. The pearls on the end will go flying off. If you find a way to catch this Dark Energy wave, like a surfer, it could also propel you along as well, only using the energy it requires to “catch it”?
