Animations showing the various stages after the Big Bang can be found at these websites: http://expositions.bnf.fr/ciel/elf/1big/big.htm and http://superstringtheory.com/cosmo/cosmo3.html. What are the major stages? What is the evidence for each of these stages?

Go to the website for the Dark Energy Survey, an international project beginning in 2012 (https://www.darkenergysurvey.org/index.shtml). What observations will be made for this project? What will it tell scientists about dark energy? Click on “News.” What is the status of this project? Are there any results yet?

Go to the website of the European Organization for Nuclear Research (CERN—http://public.web.cern.ch/public/en/Science/Recipe-en.html) and read through the pages indexed on the left. What was the role of the Higgs boson after the Big Bang? Go to CERN’s press release page (http://press.web.cern.ch/) to see what’s new in the search for the Higgs boson. (Note: The World Wide Web was invented at CERN.)

Scientists debate whether there ever can be scientific evidence for a multiverse. A good example is a discussion in the journal Scientific American. Read the article “Does the Multiverse Really Exist?” in the August 2011 issue (it is probably accessible online through your school library) and the response at http://scientificamerican.com/article.cfm?id=multiverse-the-case-for-parallel-universe. What are some of the arguments for and against multiverses?

Clips from a four-part episode of the public television series Nova called “The Fabric of the Cosmos” can be accessed on PBS’s website (http://pbs.org/wgbh/nova/physics/fabric-of-cosmos.html), and complete episodes can be viewed on the Top Documentary Films website (http://topdocumentaryfilms.com/the-fabric-of-the-cosmos). Watch the clips or at least one of the episodes. Are the arguments made in these programs compelling? Is the science explained in a way that makes sense to a general audience?
