Scientists suspect lightweight dark matter might ionize hydrogen in the Milky Way’s core. This could also explain the 511-keV ...

At any temperature, the particles (atoms and molecules) of a substance, in this case a gas, move at different speeds. If energy is added by heating, the particles move faster. If energy is removed by ...

Scientists have transformed light into a supersolid, a breakthrough merging solid and liquid properties in quantum physics.

Where there's water, there are waves. But what if you could bend water waves to your will to move floating objects? Scientists have now developed a technique to merge waves in a water tank to produce ...

To moving particles, the electric field appears as a strong magnetic field (~10 3 Tesla), enabling photons to convert into axions, and back again. An opaque titanium sheet inserted between the ...

Physicists use mathematical assumptions in many situations that forbid time from moving backwards – but that isn’t necessarily a reflection of quantum reality ...

They have a fixed shape and cannot flow The particles cannot move from place to place They cannot be compressed (squashed) The particles are close together and have no space to move into Have ...

TULELA: Solids have a fixed shape and fixed volume and cannot be compressed because in this model, there is no space for the particles to move into. Let’s add some energy to the solid.
