Elon Musk, head of SpaceX, has announced via Twitter that the company's SN8 rocket will take a test flight sometime next week. The plan is for the rocket is to soar up to 60,000 feet (18,300 meters) and then return to Earth ...

Scientists interpret physics behind invisibility cloaks

Is a perfect invisible cloak theoretically possible? Are there certain wavelengths—such as those in the visible spectrum—that can’t be made invisible? How will using imperfect materials affect the performance of a cloak? ...

Does the quantum wave function represent reality?

(Phys.org) -- At the heart of quantum mechanics lies the wave function, a probability function used by physicists to understand the nanoscale world. Using the wave function, physicists can calculate a system's future behavior, ...

Spacetime May Have Fractal Properties on a Quantum Scale

(PhysOrg.com) -- Usually, we think of spacetime as being four-dimensional, with three dimensions of space and one dimension of time. However, this Euclidean perspective is just one of many possible multi-dimensional varieties ...

Speed of light drops to zero at 'exceptional points'

Light, which travels at a speed of 300,000 km/sec in a vacuum, can be slowed down and even stopped completely by methods that involve trapping the light inside crystals or ultracold clouds of atoms. Now in a new study, researchers ...

Wind-powered car goes down wind faster than the wind

(PhysOrg.com) -- A wind-powered car has been clocked in the US traveling down wind faster than the wind. In a recent run at New Jerusalem in Tracy, California, the car reached a top speed of more than 2.85 times faster than ...
