How long will star formation endure before the eventual heat death of
In article ,
James Goetz writes: Lord Kelvin's prediction of heat death indicates the eventual end to star formation in the observable universe. Have any astrophysicists made any predictions for the endurance of star formation in the observable universe? Or does anybody here want to take a crack at predicting it? [[Mod. note -- 1. This is really an astronomy question rather than a general physics question, so I have set the Followup-To header to point to our sister newsgroup sci.astro.research . 2. As to answering your question: Trying to understand/model the star formation rate of the universe has been a major research area for decades (e.g., try the search term "star formation history of the universe" in google scholar or the ADS). But most of this focuses on the *past* star formation rate. I'm sure there are studies trying to forecast this into the future, but I don't have references handy. -- jt]] Star formation is heavily influenced by galaxy interactions. Thus, one would at least need to run galaxy-evolution simulations into the future, but no-one does this. One reason is that one can't check the simulations by comparing to observations. The other is that with time matter become more and more clumped, so more dynamic range is needed for realistic simulations. (I had never seen this discussed in the literature, but a few years ago I asked some of the main players in the field why this is the case.) |
