What two major limitations prevent us from building highenergy accelerators that are physically small?
The decay of one type of Kmeson is cited as evidence that nature favors matter over antimatter. Since mesons are composed of a quark and an antiquark, is it surprising that they would preferentially decay to one type over another? Is this an asymmetry in nature? Is the predominance of matter over antimatter an asymmetry?
(a) A particle and its antiparticle are at rest relative to an observer and annihilate (completely destroying both masses), creating two (rays of equal energy. What is the characteristic (ray energy you would look for if searching for evidence of protonantiproton annihilation? (The fact that such radiation is rarely observed is evidence that here is very little antimatter in the universe.) (b) How does this compare with the 0.511MeV energy associated with electronpositron annihilation?
If some unknown cause of red shiftsuch as light becoming "?red" from traveling long distances through empty spaceis discovered, what effect would there be on cosmology?
The peak intensity of the CMBR occurs at a wavelength of 1.1 mm. (a) What is the energy in eV at a 1.1mm photon? (b) There are approximately 109 photons for each massive particle in deep space. Calculate the energy of 109 such photons. (c) If the average massive particle in space has a mass half that of a proton, what energy would be created by convening its mass to enemy? (d) Does this imply that space is “matter dominated”? Explain briefly.
(a) What Hubble constant corresponds to an approximate age of the universe of 1010 y? To get an approximate value, assume the expansion rate is constant and calculate the speed at which two galaxies must move apart to be separated by 1 Mly (present average galactic separation) in a time of 1010 y. (b) Similarly, what Hubble constant corresponding to a universe approximately old?
(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.
