Abstract

The discovery of the accelerated expansion of the universe through observations of High-Redshift supernovae and its implication for the existence of Dark Energy as the dominant component of our universe, surely counts as one of the most important moments in the entire history of physics and astronomy. This discovery has great appeal to the general public, both because of the heroic lore to observe distant supernovae and because of the strange relativistic properties of the Dark Energy. To bring this development to the non-professionals, the Cal State L.A. Science Visualization project developed an easy to use Java based tool, which may be used in college, pre-college or public science education. The tool utilizes multimedia presentations, such as graphs or images, to simulate the search for and observations of high-redshift supernovae, and interactively leads to the discovery of the created universe fluid content. Model universes are selected in a semi-random manner, which displays range of interesting possibilities for the effective equation of state, the shape of the Hubble diagram, or the nature of the expansion. The Java-based tool is deployed through Java webstart for both high-end and low-end terminal users across platforms.
