Researchers at Caltech have come up with a new way to visualize the warping of space and time using what they call ‘Tendex’ lines, a clever way to visualize these fields similar to electric and magnetic forces.

Tendex and vortex lines provide a powerful new way to understand black holes, gravity, and the nature of the universe. “Using these tools, we can now make much better sense of the tremendous amount of data that’s produced in our computer simulations,” says Dr. Mark Scheel, a senior researcher at Caltech and leader of the team’s simulation work.

At the recent CCGrid09, a conference for cluster and grid computing, the LSU Center for Computation and Technology (CCT) won the SCALE2009 challence with an interactive system to simulate and visualize black holes and their gravitational physics.

The demonstration showed live, interactive images of the black hole data using a scientific visualization system distributed across LONI. The CCT group built tangible interaction devices, which they provided on the show floor in Shanghai, allowing observers to interact in real-time with the visualization process.

They ran the simulation on TACC’s Ranger system, using 2048 cores.  As an extra “fun” bonus, they managed to connect the simulation to social networks so that it could announce runtime information via Twitter and post real-time images of the simulation to Flickr.  Videos of the simulation can be seen at the CactusCode site.
