Quintessence is an energy field that can change over time. It changes slowly and almost constantly. It is a property of space itself. During its slow walk, gravity ties the galaxies together into gigantic pods. When gravity can no longer hold things...
HOT AND COLD MATTER DARK ENERGY In cosmology, quintessence is a natural form of energy distinct from any ordinary matter or radiation or even “dark matter.” Its bulk properties – energy density, pressure, and so forth – lead to novel behavior and unusual astrophysical...
Gravity’s gentle tug on the cosmos: Newton’s law of universal gravitation is that every particle attracts every other particle in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the...
The matter is anything that has mass and takes up space (volume). It made all matter up of atoms. The atom has a nucleus containing particles of positive charge (protons) and particles of neutral charge (neutrons). Surrounding the nucleus of an atom are shells...
