Produce and detect gravitational fields at will using magnetic fields, control them for studying them, work with them to produce new technologies — it sounds daring, but Prof. André Füzfa of Namur University has proposed just that in an article published in the scientific journal Physical Review D. If followed, this proposal could transform physics and shake up Einstein’s theory of general relativity.

At present, scientists study gravitational fields passively: they observe and try to understand existing gravitational fields produced by large inertial masses, such as stars or Earth, without being able to change them as is done, for example, with magnetic fields. It was this frustration that led Füzfa to attempt a revolutionary approach: creating gravitational fields at will from well-controlled magnetic fields and observing how these magnetic fields could bend space-time.

In his article, Füzfa has proposed, with supporting mathematical proof, a device with which to create detectable gravitational fields. This device is based on superconducting electromagnets and therefore relies on technologies routinely used, for example, at CERN or the ITER reactor.

“You’re way too low. You need to get back on course!” I’m soaring through space high above Mars, steering my way towards the ship that’s going to take me back to Earth after hundreds of days stranded on the Red Planet. I’m changing direction using the air escaping from my pierced left glove, which I’m holding behind my back so I can move forward. I look over my shoulder and see the rocket I used to escape hanging against a Martian backdrop; above and around me, there’s only the void. My return home might be in jeopardy.

I change my left hand’s angle and approach a white beam of light, where my commander is waiting to drag me onto her waiting spacecraft. She wraps me in her arms, and I feel a little jolt when our helmets clunk together. Having finally achieved relative safety, I drop the controllers I’ve been holding and lift the Oculus Rift headset I’ve been wearing for the last 20 minutes into the hands of a nearby attendant. I’ve just finished The Martian VR Experience, which is coming to a virtual reality headset near you sometime this year, and the moments I just spent hurtling through the solar system are giving me a new appreciation for the solid footing of this Las Vegas nightclub.

DNA is similar to a hard drive or storage device, in that contains the memory of each cell of every living, and has the instructions on how to make that cell. DNA is four molecules combined in any order to make a chain of one larger molecule. And if you can read that chain of four molecules, then you have a sequence of characters, like a digital code. Over the years the price of sequencing a human genome has dropped significantly, much to the delight of scientists. And since DNA is a sequence of four letters, and if we can manipulate DNA, we could insert a message and use DNA as the storage device.

At this point in time, we are at the height of the information age. And computers have had an enormous impact on all of our lives. Any information is able to be represented as a collection of bits. And with Moore’s law, which states that computing power doubles every 18 months, our ability to manipulate and store these bits has continued to grow and grow. Moore’s law has been driven by scientists being able to make transistors and integrated circuits continuously smaller and smaller, but there eventually comes a point we reach in which these transistors and integrated circuits cannot be made any smaller than they already are, since some are already at the size of a single atom. This inevitably leads us into the quantum world. Quantum mechanics has rules which are, in many ways, hard for us to truly comprehend, yet are nevertheless tested. Quantum computing looks to make use of these strange rules of quantum physics, and process information in a totally different way. Quantum computing looks to replace the classical bits which are either a 0 or a 1, with quantum bits, or qubits, which can be both a 0 and a 1 at the same time. This ability to be two different things at the same time is referred to as a superposition. 200 qubits hold more bits of information than there are particles in the universe. A useful quantum computer will require thousands or even millions of physical qubits. Anything such as an atom can serve as a quantum bit for making a quantum computer, then you can use a superconducting circuit to build two artificial atoms. So at this point in time we have a few working quantum transistors, but scientists are working on developing the quantum integrated circuit. Quantum error correction is the biggest problem encountered in development of the quantum computer. Quantum computer science is a field that right now is in its very early stages, since scientists have yet been able to develop any quantum hardware.
