This is a timeline of subatomic particle discoveries, including all particles thus far discovered which appear to be elementary (that is, indivisible) given the best available evidence. It also includes the discovery of composite particles and antiparticles that were of particular historical importance.
2000 scientists at Fermilab announce the first direct evidence for the tau neutrino, the third kind of neutrino in particle physics. [30] 2000 CERN announced quark-gluon plasma, a new phase of matter. [34] 2001 the Sudbury Neutrino Observatory (Canada) confirm the existence of neutrino oscillations.
This also means it is the first elementary scalar particle discovered in nature. [32] By March 2013, the existence of the Higgs boson was confirmed, and therefore the concept of some type of Higgs field throughout space is strongly supported.
1964 - First black hole, Cygnus X-1, discovered; 1964 – CP violation discovered by James Cronin and Val Fitch. 1965 – Arno Penzias and Robert Wilson: Cosmic Microwave Background (CMB) discovered; 1967 – Unification of weak interaction and electromagnetism (electroweak theory) 1967 – Solar neutrino problem found
While the “Epoch of Reionization” sounds like the title of a sci-fi novel destined for a Hugo award, this very real era of the universe featured the first light from the very first stars.
The neutrino [a] was postulated first by Wolfgang Pauli in 1930 to explain how beta decay could conserve energy, momentum, and angular momentum ().In contrast to Niels Bohr, who proposed a statistical version of the conservation laws to explain the observed continuous energy spectra in beta decay, Pauli hypothesized an undetected particle that he called a "neutron", using the same -on ending ...
But unlike the jet formed by J1601+3102, Porphyrion was found 7.5 billion light-years away from Earth in what’s called the “nearby” universe, rather than the early universe, according to the ...
