  • The intrinsic angular momentum of a particle is its spin. Its angular momentum results in the particle’s motion in space. (It’s orbital angular momentum). The conservation of energy rule applies to particle spin as well.
    The conservation laws include conservation of mass (now conservation of mass and energy after Einstein’s Theory of Relativity), conservation of linear momentum, conservation of angular momentum, and conservation of electric charge.
    Is the law of conservation of energy valid at a quantum level? - Quora
    The principle of energy conservation states that energy is neither created nor destroyed. It may transform from one type to another.
    As objects move around over time, the energy associated with them, e.g., kinetic, gravitational potential, heat, might change forms, but if energy is conserved, then the total will remain the same. Conservation of energy applies only to isolated systems.
  • Space and time don’t exist without matter, they exist only related to matter. Therefore, space and time are not quantities, but qualities of reality. Matter tells space how to curve, and curved space tells matter how to move. 
  • Image result
  • Quantum mechanics tells us that there is no such thing as empty space. A roiling cloud of particles and antiparticles, which flare into existence and almost instantaneously fade back into nothingness, actually filled even the most perfect vacuum.
  • Space is not empty. A point in outer space is filled with gas, dust, a wind of charged particles from the stars, light from stars, cosmic rays, radiation left over from the Big Bang, gravity, electric and magnetic fields, and neutrinos from nuclear reactions.
  • Bosons and fermions, fundamental particles - for beginners: from fizzics.org - YouTube
  • A fermion is any particle that has an odd half-integer (like 1/2, 3/2, and so forth) spin. … Bosons are those particles that have an integer spin (0, 1, 2…). All the force carrier particles are bosons, as are those composite particles with an even number of fermion particles (like mesons).
  • Fermions include particles in the class of leptons (e.g., electrons, muons), baryons (e.g., neutrons, protons, lambda particles), and nuclei of odd mass number (e.g., tritium, helium-3, uranium-233).
  • Physics tells us that fundamental particles come in two basic varieties: bosons, which have integer values of intrinsic angular momentum or “spin”, and fermions, which have half-integer spin. Bosons include force-carrying particles such as the photon, W, and Z and follow Bose-Einstein statistics. Bosons are force-carrying particles.
  • Chapter 16 The Sun Our Star The Sun
  •  About 100 trillion neutrinos pass through your body every second. Most of those neutrinos come from the sun, which releases a constant stream of low-energy neutrinos out into space.
  • Cooling of a trapped ion to the quantum regime
  • Image result for fermions and bosons
    They usually associate fermions with matter while Bosons are the force carriers. Examples of Fermions: Leptons (Electrons, Neutrinos) Quarks (Up, Down.), Baryons (Protons, Neutrons).
