He ranks among history's most influential mathematicians and has ...
22 hours ago · Careful measurement of a range of phenomena, from the motion of enormous clusters of galaxies to the rate at which individual galaxies spin, have indicated that all the stuff astronomers can see – the trillions of stars dotted across the night sky – contributes just a fraction of the total mass of the universe.
22 hours ago · History Early history. The hypothesis of dark matter has an elaborate history. In the appendices of the book Baltimore lectures on molecular dynamics and the wave theory of light where the main text was based on a series of lectures given in 1884, Lord Kelvin discussed the potential number of stars around the Sun from the observed velocity dispersion of the stars near the Sun, assuming that ...
22 hours ago · Zero-point energy ( ZPE) is the lowest possible energy that a quantum mechanical system may have. Unlike in classical mechanics, quantum systems constantly fluctuate in their lowest energy state as described by the Heisenberg uncertainty principle. [1] Therefore, even at absolute zero, atoms and molecules retain some vibrational motion.

22 hours ago · The brighter concentration, designated as P1, is offset from the center of the galaxy. The dimmer concentration, P2, falls at the true center of the galaxy and contains a black hole measured at 3–5 × 10 7 M ☉ in 1993, and at 1.1–2.3 × 10 8 M ☉ in 2005. The velocity dispersion of material around it is measured to be ≈ 160 km/s (100 ...
