Dark matter’s effect on stellar streams should be measurable, says astrophysicist.

Introducing a slow-light medium into an optical microresonator extends the lifetime of a photon circulating in the device by several orders of magnitude.

The EMPT thruster, funded by NASA, is a 1 kW-class RMF thruster, operates on the same physics principles as the ELF thruster. This device, less than 4 inches in diameter, has proven that pulsed inductive technolgoies can be succesfully miniaturized. Indeed, this thruster has demonstrated operation from 0.5 to 5 Joules, as well as the first pulsed inductive steady state operation. The EMPT has demonstrated greater than 1E8 continuous plasma discharges.

Are parallel universes real?
Right now there might be a whole other universe where instead of brown hair you have red hair, or a universe where you’re a classical pianist, not an engineer. In fact, an infinite number of versions of you may exist in an infinite number of other universes.

The idea sounds like science fiction, but multiverse theories — especially those that are actually testable — are gaining traction among physicists. Here are three of the most compelling theories:

If the universe is infinite, multiple universes probably exist.

The black holes that kicked off the first detection of gravitational waves seem to be the right size and frequency to be long-sought primordial black holes.

Going back to the start, how did you come to studying Theoretical Physics?

As with most people my path was determined by a series of choices involving random factors. I liked mathematics and physics at school, and did well in the olympiads, but I liked also literature, history, etc. At the age of fourteen I choose a technical-type high school oriented at nuclear disciplines, as popular then as they are despised by many these days, probably because it was one of the most difficult and challenging ones.

The way from there to the Technical University was straightforward. Since I have the need to understand things from the first principles, I drifted gradually towards theoretical physics and it was only natural that in the middle of my studies, corresponding roughly to the bachelor degree nowadays, I ended up at the Theoretical Physics Department of the Charles University, where I subsequently graduated.

Physicists say a supercomputer simulation of blood flow around the entire human body is showing promise, based on an experimental test.

Directed by Carl Loeffler, The Networked Virtual Art Museum was a pioneering project that investigated telecommunications and virtual reality, and provided a basis for multiple users located in distant geographical locations to be conjoined in the same virtual, immersion environment. The project employed telecommunication hardware, as well as the hardware associated with virtual reality: data eyephones and multi-directional navigation devices. The immersion environment was an art museum with galleries offering various exhibitions.
