A massive galaxy that appeared less than two billion years after the Big Bang does not rotate on itself. This specimen, named XMM-VID1-2075, contradicts all astronomers' expectations. According ...

Almost all measurements of motion in astronomy make use of a law of physics called the Doppler effect. This change in the wavelength (or frequency, color, or pitch) of a wave emitted by a moving ...

Scientists have directly watched angular momentum move through a crystal for the very first time — and discovered a bizarre ...

The vibrations of atoms in a crystal generate one type of rotation, an intrinsic spin-like trait called angular momentum. For ...

Researchers discovered that atomic rotations inside a crystal can unexpectedly flip direction while still obeying the laws of ...

Everyone loves perpetual motion machines. They are a representation of the highest level of creativity in finding loopholes in the laws of physics. Let's take a look at this one. What is a perpetual ...
