B I B G B A N G O N L I N E . O R G is your WWW resource for simulating the creation of light elements in the Early Universe. This site hosts an online Big Bang Nucleosynthesis code and provides extensive resources for studies of the Big Bang.

C O M P U T E
The bigbangonline suite of codes is a cloud computing system that enables researchers to set up, execute, and visualize a custom Big Bang Nucleosynthesis calculation, and compare the results to observations of the primordial light element abundances to constrain the baryon density. Monte Carlo simulations can also be run wherein uncertainties in the input thermonuclear reaction rates are propagated through the simulation to give uncertainties in primordial abundance predictions, and the corresponding uncertainties in the baryon density constraint.

R E S O U R C E S
We provide links to information on thermonuclear reaction rates of the light elements, the latest revisions of Big Bang Nucleosynthesis calculations, general information on Cosmology and the Big Bang, and much more.
