In a groundbreaking study published in Physical Review Letters, physicists from ETH Zurich, in collaboration with teams from ...

Matter is defined as that which 1) has mass and 2) has volume or takes up space. Mass is an intrinsic property whose base SI unit is the kilogram (kg).

The invisible dark matter is one of the universe's biggest mysteries, and its existence is confirmed only by the ...

Inspired by superconductivity, a strange new theory that seeks to explain dark matter might explain dark energy, too ...

Despite decades of searching, scientists still haven’t found the elusive substance that holds galaxies together: dark matter.

Around 68 percent of the remaining mass is dark energy, with just five percent left to ordinary “baryonic” matter, which are the objects we can directly observe.

M ost of the matter in our universe is invisible. We can measure the gravitational pull of this “dark matter” on the orbits of stars and galaxies. We can see the way it bends light around ...

Albert Einstein’s famous formula established the interchangeability of mass (matter) and energy in 1905. In 1945, this equivalency was demonstrated to all with the detonation of the first atomic ...

The latest measurement pushes the possible mass of the neutrino lower than the previous limit set in 2022 by the KATRIN collaboration, of no more than 0.8 electronvolts. It is also nearly twice as ...

But as usual in science, there's more to the story. Forces and Fields On human scales of mass and distance, matter obeys the laws of motion described by Sir Isaac Newton.
