1 day 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 ...
4 days ago · A singularity hints at the fact that general relativity can’t be a complete description of the basic rules of physics. Efforts to form such a description, which would require reconciling general relativity with quantum mechanics, are ongoing. Ling said he sees the new paper as a steppingstone to such a theory.
3 days ago · Special Theory of Relativity: Perhaps his most famous contribution, the special theory of relativity, introduced the revolutionary concept that the laws of physics are the same for all non-accelerating observers. This theory led to the iconic equation 𝐸 = 𝑚 𝑐 2 E=mc 2 , which describes the equivalence of mass and energy.
5 days ago · The team of scientists — from the Research Center for the Early Universe (RESCEU) and Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU, WPI) at the University of Tokyo — applied a theoretical framework combining classical field theory, Einstein's special relativity theory, and quantum mechanics to the early universe.
4 days ago · The hypothesis, therefore, is that if massive, distant objects (known as delocalized states) can be entangled, then gravity must be quantum. Revealing gravity’s quantum nature without generating entanglement. The problem is that it is extremely difficult to make large objects behave as quantum particles.
3 days ago · 1 other. contributed. Quantum entanglement occurs when a system of multiple particles in quantum mechanics interact in such a way so that the particles cannot be described as independent systems but only as one system as a whole. Measurement (e.g. of the spin of an entangled electron) may instantaneously affect another electron's spin at an ...
4 days ago · This resulted in Einstein's theory superseding Newtonian physics. Thereafter, German mathematician Theodor Kaluza promoted the idea of general relativity with a fifth dimension, which in 1921 Swedish physicist Oskar Klein gave a physical interpretation of in a prototypical string theory , a possible model of quantum gravity and potential theory ...
