In the Large Hadron Collider, or LHC, scientists smashed together beams of protons and looked for the Higgs boson. On July 4, 2012, they announced that that Higgs boson had been finally found. […]
With the discovery of W and Z bosons, much of electroweak theory had been confirmed. In 1991, the CERN laboratory turned on a much bigger accelerator, called LEP, to look for Higgs boson. […]
Modern electroweak theory predicted that there should be a massless photon, a massive neutral particle called Z boson, two massive electrically charged particles called W bosons, and a massive and neutral particle called Higgs boson. […]
Electromagnetism and weak nuclear force were unified into a combined force called the electroweak force. The electroweak unification predicted four particles that carried the electroweak force and had zero mass. […]
The fears regarding subatomic black holes are not founded. Physicists like Stephen Hawking believe that even if subatomic black holes are real, they evaporate away before becoming dangerous. […]
Though they are certain worries vis-à-vis the particle accelerators, they are not backed by science. One of the concerns is that large accelerators might make subatomic particles, called ‘strangelets’. […]
Nuclear fusion is an astronomically powerful source of energy. If harnessed, it could prove unimaginably useful for humanity’s purposes. How does nuclear fusion make energy? […]
0.6 microns is the most popular wavelength to have in sunlight. When we measure the flux density of the Sun, as a function of wavelength, we find it’s a pretty good fit to a theoretical Planck spectrum. […]
Photons and particles have different properties. Photons sail right through each other and don’t collide. Also, they appear out of nowhere whenever a charged particle accelerates, while a particle can’t spontaneously appear or vanish. […]
When some particles are put in a sealed box and energy is injected into it, after a while their positions and velocities will become randomized and they will share the total energy more-or-less equally. […]
