6) In quantum physics, a subatomic particle appears only when it is observed or measured.
On the other hand, at the same time, this model introduces these new simple elements: the idea that space is a-temporal and has a granular structure at the Planck scale and the fact that the state of each subatomic particle can be always seen as the consequence of the vibration of one or more QS at appropriate frequencies.
One German molecular physicist told me many years ago that the subatomic particles being studied by physicists, using very strong microscopic instrument, behave very strangely.
While Americans spent part of Wednesday watching small explosions of color in the sky, an elite group of scientists spent the day announcing their conclusions from months of studying collisions of subatomic particles on colorful computer screens.
A subatomic particle can also move forward in time-faster than light, or backward, which is impossible under classical physics.
The basic theory of the Higgs boson is the simplest way to account for the masses of subatomic particles. But there are other ways that the Higgs boson could work.
It was the year 2000, and scientists at a European particle collider observed possible traces of the subatomic particle known as the Higgs boson--the presumed origin of mass itself and the most-wanted quarry in high-energy physics today.
For the first time, physicists have measured the planet's mass using neutrinos, minuscule subatomic particles that can pass straight through the entire planet.
Installed on the International Space Station in 2011, the Alpha Magnetic Spectrometer collects and identifies cosmic rays, charged subatomic particles that permeate the galaxy (SN: 3/21/15, p.
In 1964, John Bell developed a theorem to support EinsteinAEs supposition of ospooky actions at a distance,o or unexpected behaviors of subatomic particles. In this collection of papers, author Christian demonstrates that BellAEs theorem is flawed and argues that long-distance actions between subatomic particles have another explanation.
Higgs "for the theoretical discovery of a mechanism that contributes to our understanding of the origin of mass of subatomic particles, and which recently was confirmed through the discovery of the predicted fundamental particle, by the ATLAS and CMS experiments at CERN's Large Hadron Collider".
