You’d be instantly where you want to be if you moved at the speed of light. Indeed, light-speed travel has been a fantasy of many scientists and aerospace engineers who look for ways to achieve it.
And now, it seems Elon Musk and NASA have broken that fantasy code to build a light-speed engine that defies the laws of physics.

It’s said that the clock is always ticking, but there’s a chance that it isn’t. The theory of “presentism” states that the current moment is the only thing that’s real, while “eternalism” is the belief that all existence in time is equally real. Find out if the future is really out there and predictable—just don’t tell us who wins the big game next year.

This video is episode two from the series “Mysteries of Modern Physics: Time”, Presented by Sean Carroll.

Researchers at the Department of Energy’s Oak Ridge National Laboratory are teaching microscopes to drive discoveries with an intuitive algorithm, developed at the lab’s Center for Nanophase Materials Sciences, that could guide breakthroughs in new materials for energy technologies, sensing and computing.

“There are so many potential materials, some of which we cannot study at all with conventional tools, that need more efficient and systematic approaches to design and synthesize,” said Maxim Ziatdinov of ORNL’s Computational Sciences and Engineering Division and the CNMS. “We can use smart automation to access unexplored materials as well as create a shareable, reproducible path to discoveries that have not previously been possible.”

The approach, published in Nature Machine Intelligence, combines physics and machine learning to automate microscopy experiments designed to study materials’ functional properties at the nanoscale.

Australian mining company Fortescue is looking to reduce the carbon footprint of its operations by allowing a specially designed electric “Infinity Train” to roll down a hill to recharge its massive batteries — without ever relying on an external charging system.

“The Infinity Train has the capacity to be the world’s most efficient battery electric locomotive,” Fortescue CEO Elizabeth Gaines said in a statement. “The regeneration of electricity on the downhill loaded sections will remove the need for the installation of renewable energy generation and recharging infrastructure, making it a capital efficient solution for eliminating diesel and emissions from our rail operations.”

It’s a cleverly designed system: since the train is far lighter on the way up, it will generate enough energy fully loaded with iron ore on the way down to make it back up to the mine. In other words, it might sound like a perpetual motion machine — which is impossible, of course — but in reality it’s just an ingenious exploit of conventional physics.

When researchers simulated the exhaust from a Falcon 9 rocket launch, they found that it releases high concentrations of CO₂ in the upper atmosphere.

If there was a wormhole in the center of our galaxy, how could we tell? Two physicists propose that carefully watching the motions of a star orbiting the Milky Way’s supermassive black hole might help scientists start to check. The researchers published the idea in a recent paper in the journal Physical Review D.

A wormhole is a hypothetical concept that connects two separate areas of space-time. Wormholes often appear in science fiction narratives like the 2014 film Interstellar as a convenient way to get from point A to point B in the vast universe. Physicists have many theories that describe how wormholes might behave, if they exist, but haven’t yet found any.

Though her experiments defied long-held laws about symmetry in the physical world, Wu was not regarded as a peer of those whose work she enabled.
