The universe is continuously expanding, yet the exact rate at which it does so remains unclear, and has so far only been approximated using NASA's Hubble Space Telescope and other similar instruments. Moreover, in recent ...
The way electrons flow in a material determines its electronic properties. For example, when a voltage is sustained across a conducting material, electrons start flowing, generating an electrical current. These electrons ...

(PhysOrg.com) -- To improve transmission speeds, the Internet has transitioned over the years from one using copper to fiber optic cabling. Unfortunately, this has caused a bottleneck to occur where the light signals meet ...
It's the biggest problem in physics: the matter we can see in the universe accounts for just five per cent of the observed gravity that holds galaxies together.
