Universal Big Bang Lithium Deficit Confirmed

An anonymous reader writes New observations of the star cluster Messier 54 show that it is just as deficient in lithium as our own galaxy, furthering a mystery about the element's big bang origins. "Most of the light chemical element lithium now present in the Universe was produced during the Big Bang, along with hydrogen and helium, but in much smaller quantities. Astronomers can calculate quite accurately how much lithium they expect to find in the early Universe, and from this work out how much they should see in old stars. But the numbers don't match — there is about three times less lithium in stars than expected. This mystery remains unsolved, despite several decades of work."

      "Solved" isn't a term properly used in the sciences, and your quite legitimate confusion here is a nice example of why.

      Science is the discipline of publicly testing ideas by systematic observation, controlled experiment, and Bayesian inference. It does not produce certainty, but rather knowledge. Unfortunately, because science is still a very young discipline (only three hundred years old) we have yet to really update our language to accommodate it, so we still talk in terms of "solution" and "proof" and the like, as if we were philosophers seeking after some chimeral goal like "certainty" or the ability to turn base metals into gold.

      The questions scientists are interested in here are:

      1) "Which is more plausible given the evidence we have: that we are computing something wrong in our Big Bang nucleo-synthesis calculations using existing physics; that our measurements of lithium abundance are wrong; that there is new physics that affects lithium production in the Big Bang; that our chemical evolution calculations are wrong for some reason; or that something else entirely is going on that we are missing?"

      and:

      2) "What new evidence might we gather to clarify the situation given we currently don't have a stand-out idea that is sufficiently more plausible than the rest that no one can be bothered to do further investigations?"

      Science is a human discipline, and as such is never "settled" except insofar as no on can be arsed to look at some question more deeply because the plausibility of the currently-best answer is so high (for example, while I think it very likely the Earth is heating up, I support further research like better satellite measurements of albedo: http://www.washington.edu/alum...)

      With regard to lithium, we have a pretty good handle on Big Bang production assuming there is no new physics, but lithium has a number of characteristics that make it more strongly subject to the forces of what cosmologists call "chemical evolution"--the way the chemical composition of the universe changes through time due to stellar and other processes. The Korn et al work points to one particular way primoridal lithium could be hidden away. In the '90's there was similar work being done to show that various other processes could actually break lithium nuclei up over the course of the history of the universe.

      Then there is also the problem that the whole "missing lithium" thing could be a result of a local anomaly in lithium abundance: after all, we have only sampled a small part of the universe. The work this /. post is about focuses on extending the reach of measurements to other galaxies, which is a start, although one could also imagine large-scale enrichment processes in the early universe that put us in a lithium-poor bubble, so no-doubt "additional work is required" to reach a sufficiently strong consensus that the missing lithium has been explained well enough to be not worth bothering with any more.

    Go ahead, celebrate your ignorance. It's funny, so laugh it up.

    This is talking about big bang nucleosynthesis. The energies in question are reachable by our current particle accelerators, which gives us a relatively good understanding of the physics involved. Lithium was theorized to be a relatively small percentage of the mass created during this period, and this study gives evidence that it is smaller than previously calculated. Generally, when one is looking at physical discrepancies, the ultimate prize would be to find evidence of new physical phenomenae, these days usually referred to as 'Beyond the Standard Model' (BtSM). However, in this case it's more of a refinement to the theory -- just trying to better understand natural history. None of the work involved has been useless, and I don't know where you get that idea; this study is confirming previous results, not forging any new ground. Expecting practical results from astrophysics doesn't make a great deal of sense to me unless you're in the habit of dragging new stars home as pets.

    I'm tempted to say something snarky about the possibility of converting Christians to science, but frankly those kind of biases don't deserve promotion, even in jest.

  43. Precision vs. accuracy by GPS+Pilot · · Score: 1

    Another journalist misuses the word "accurately."

    Astronomers can calculate quite accurately how much lithium they expect to find in the early Universe

    They can calculate it quite precisely; but if the number doesn't match observations, the model is not accurate.
