- (a) Estimate the mass of the luminous matter in the known universe, given there are 1011 galaxies, each containing 1011 stars of average mass 1.5 times that of our Sun. (b) How many protons (the most abundant nuclide) are there in this mates? (c) Estimate the total number of particles in the observable universe by multiplying the answer to (b) by two, since there is an electron for each proton, and then by 109, since there are far more particles (such as photons and neutrinos) in space than in luminous matter.arrow_forwardMore than 60 years ago, future Nobel laureate Sheldon Glashow predicted that if an antineutrino — the antimatter answer to the nearly massless neutrino — collided with an electron, it could produce a cascade of other particles. The Glashow resonance phenomenon is hard to detect, in large part because the antineutrino needs about 1,000 times more energy than what's produced in the most powerful colliders on Earth. 1. What is the threshold antineutrino energy for the Glashow resonance in peta electronvolts (PeV)? 2. What is this threshold energy in units of joules? 3.Now consider a baseball with the same kinetic energy as that of the Glashow resonance. What speed in m/s would correspond to this energy? 4.What is this rate in units of inches/second?arrow_forwardI need the answer quicklyarrow_forward

What is the mass (calculate both in kg and unified mass units, u) ofthe β -particle? Which particle (α or β) is more massive? Which particle has agreater amount of charge (α or β)?

What is the threshold energy needed to produce a Higg's Boson. Use the following estimates of the masses: m, = 1 [GeV] and mH = 125 [GeV]. The Higgs boson will eventually decay into leptons and protons (a particle physicist will tell you that the Higgs boson will decay through different channels).
