Evolution of the Universe - GigaPan Time Machine Jump to: From GigaPan Time Machine Direct Cosmological Simulations of the Growth of Black Holes and Galaxies This timelapse shows the distribution of matter in a simulated universe on large scales. The computer simulation was carried out using the cosmological hydrodynamic simulation code P-Gadget on facilities provided by the Moore Foundation in the McWilliams Center for Cosmology at Carnegie Mellon University. The density of matter is shown on a false color scale, with the densest regions in yellow and the least dense in red and black. As the universe evolves from early times (it starts at an age of 10 million years after the Big Bang) the initially small fluctuations grow through the action of gravity until in the last frame (which represents the universe 14 billion years later, at redshift z=0, the present day) there are large clusters of galaxies present with vast, mostly empty spaces in between. Galaxy cluster Watch a time warp of the formation of a cluster of galaxies. Void
HyperPhysics Concepts About HyperPhysics Rationale for Development HyperPhysics is an exploration environment for concepts in physics which employs concept maps and other linking strategies to facilitate smooth navigation. For the most part, it is laid out in small segments or "cards", true to its original development in HyperCard. Part of the intent for this exploration environment is to provide many opportunities for numerical exploration in the form of active formuli and standard problems implemented in Javascript. New content for HyperPhysics will be posted as it is developed. A resource that was initiated as a resource for local high school physics teachers whom I had taught has expanded into an intensively used website worldwide. CD or DVD versions have been sent to 86 countries to date, and translations into German, Italian, Chinese, and Español have been licensed and are underway.
