WebThe recombination epoch begins at around 18,000 years, as electrons are combining with helium nuclei to form He+ . At around 47,000 years, [2] as the universe cools, its behavior begins to be dominated by matter rather than radiation. At around 100,000 years, after the neutral helium atoms form, helium hydride is the first molecule. WebThe timeline of the Era of Atoms is between 500,000 years to 1 billion years after the Big Bang. Within this timeline, the fully ionized particles combined with the free electrons; and the photons with specific line energies were absorbed by matter. In …
WebThe Particle Era follows the Electroweak Era. This era occurs between 10^-12 and 10 seconds after the Big Bang.

The global fit of the Standard Model to electroweak precision data, routinely performed by the LEP electroweak working groups and others, has been revisited in view of (i) the development of the new generic fitting package, Gfitter, (ii) the insertion of constraints from direct Higgs searches at LEP and Tevatron, and (iii) a more thorough …
WebIn the 1960s, the electroweak theory was developed by Steven Weinberg, Sheldon Glashow, and Abdus Salam. This theory proposed that the electromagnetic and weak nuclear forces are identical at sufficiently high energies. At lower energies, like those in our present-day universe, the two forces remain united but manifest themselves in different ways.
