It has been predicted that particles with imaginary mass, called tachyons, would be able to travel faster than the speed of light. There has not been any experimental evidence for tachyons occurring naturally. Here, we propose how to experimentally simulate Dirac tachyons with trapped ions. Quantum measurement on a Dirac particle simulated by a trapped ion causes it to have an imaginary mass so that it may travel faster than the effective speed of light. We show that a Dirac tachyon must have spinor-motion correlation in order to be superluminal. We also show that it exhibits significantly more Klein tunneling than a normal Dirac particle. We provide numerical simulations of realistic ion systems and show that our scheme is feasible with current technology.

Radically often it seems like something out of science fiction. But every day that passes we get closer to the technological singularity.

Physicists can now simulate the interiors of black holes using high-powered computers–and it looks like science fiction authors were right: black holes could be portals for space travel.
Arca Space Corporation in New Mexico has developed an electronic flying vehicle that can hover over any terrain, including water. The design can hold up to 243 lbs and flies a foot above the ground.
The ArcaBoard’s creators are calling it the first revolutionary breakthrough in motion since the bicycle, automobile, and airplane, and say it will allow every person to fly whenever they want.

At the rate of 21st century technological innovation, each year brings new breakthroughs across industries. Advances in quantum computers, human genome sequencing for under $1,000, lab-grown meat, harnessing our body’s microbes as drugs, and bionic eye implants that give vision to the blind —the list is long.
As new technologies push the boundaries of their respective industries, fields are now maturing, growing, and colliding with one another. This cross-pollination of ideas across industries and countries has changed the world—and will continue to—and it’s one of the reasons Singularity University exists.
At a time when the global technology giants are set to leverage the benefits of AI for your daily lives, India seems to be reluctant to get on to this bus.
The Milky Way and hundreds of galaxies surrounding it are being drawn toward a mysterious force scientists call the “Great Attractor”.
And it took the Commonwealth Scientific and Industrial Research Organisation’s (CSIRO) Parkes telescope to see them.
The force was first revealed back in the 1970s, when it was discovered that the Milky Way was one of hundreds of galaxies deviating from the “universe is expanding” model.
“There’s a reason the only robot a person is likely to have in their home today is a cleaning robot,” founder Shlomo Schwarz tells me during a recent call. “It gives added value to the person. You buy a cleaning robot because it cleans your house. You’re not buying a friend.” — when we say value; how do we know for sure. I know many consumers who bought the iRobot vacuums and don’t use them because for many of the women in my own family found it was limited in its usage.
An Israeli startup is modeling its Linux-based, Raspberry Pi-powered robot on the smartphone developer ecosystem.
