Simulations back up theory that Universe is a hologram

Nature

A team of physicists has provided some of the clearest evidence yet that our Universe could be just one big projection.

In 1997, theoretical physicist Juan Maldacena proposed¹ that an audacious model of the Universe in which gravity arises from infinitesimally thin, vibrating strings could be reinterpreted in terms of well-established physics. The mathematically intricate world of strings, which exist in nine dimensions of space plus one of time, would be merely a hologram: the real action would play out in a simpler, flatter cosmos where there is no gravity.

3D holograms that can be touched and felt

Immersive, highly visual, 3D environments are now on the horizon after British scientists managed to recreate mid-air sensory experiences by controlling sound waves to project 3-D haptic holograms that can be seen and felt.

A team from the University of Bristol’s Interaction and Graphics research group, using the UltraHaptics, a system for creating haptic feedback in mid-air, were successful in testing several shapes, including spheres and pyramids.

'Impossible' rocket drive works and could get to Moon in four hours

Telegraph

Interplanetary travel could be a step closer after scientists confirmed that an electromagnetic propulsion drive, which is fast enough to get to the Moon in four hours, actually works.

The EM Drive was developed by the British inventor Roger Shawyer nearly 15 years ago but was ridiculed at the time as being scientifically impossible.

It produces thrust by using solar power to generate multiple microwaves that move back and forth in an enclosed chamber. This means that until something fails or wears down, theoretically the engine could keep running forever without the need for rocket fuel.

Space Tech Makes Everything Better, Even Wind Farms

Wired

The history of innovation is full of happy accidents. The World Wide Web? Came from particle physicists at CERN who wanted easier internal communication. Wi-Fi? Invented by radio astronomers in Australia trying to detect pulses of radio waves from exploding black holes. And it took a failed space mission to fix the one of the biggest problems in green energy: The awful grinding noise of a wind farm at work.
