Strange Posted July 25, 2015 Share Posted July 25, 2015 Does the distribution of elementary particles in the Universe presage the age of the Universe ? I'm not quite sure what you mean. The relative quantities of hydrogen and helium which make up pretty much all the matter in the universe are exactly what is predicted by the big bang model. So that is good confirmatory evidence for the model and the age of the universe. Link to comment Share on other sites More sharing options...

So that is good confirmatory evidence for the model and the age of the universe. Neutrinos are ubiquitous. Protons (H+) are essentially the raw material of stars and as you rightly point out they are a good indicator of stellar processes and age of the Universe. Neutrinos on the other hand are less likely to be pointers in this direction. Are there any other particles that indirectly correlate to the age of the Universe ?

Strange Posted July 27, 2015 Share Posted July 27, 2015 Neutrinos are ubiquitous. Protons (H+) are essentially the raw material of stars and as you rightly point out they are a good indicator of stellar processes and age of the Universe. Neutrinos on the other hand are less likely to be pointers in this direction. As with hydrogen, pretty much all the neutrinos in existence were created in the big bang. In the same way that there is the cosmic microwave background (which is one of the best indicators of the age and nature of the universe) there should also be a cosmic microwave background. This would have emerged about 380,000 years ealier and would probably tell us a lot about the early universe. Unfortunately, we are (currently) unable to detect such low energy neutrinos. https://en.wikipedia.org/wiki/Cosmic_neutrino_background Link to comment Share on other sites More sharing options...
