A new way to visualize warped space and time

Attempts to understand the warping of space and time is room sizes and positions, so something like a scene from Alice where change visualization's adventures in Wonderland. The most common description of the warping of space-time is distorted like a heavy object a stretched elastic sheet. But in fact, physicists say, they are forgiven it is the details of what really able to understand, so complicated, is to have been. But combined offer new conceptual tools, theory and computer simulations a better way for scientists, what takes place when the fabric of space changes gravity of an object or event to make visible.

Researchers at Caltech, Cornell University and the National Institute for theoretical physics in South Africa developed conceptual tools, which they call Tendex lines and vortex lines represent the gravitational waves. The researchers say that Tendex and vortex caused describe the gravitational forces lines by warped space-time and are analogous to the electric and magnetic field lines, describing the electric and magnetic forces.

"Tendex lines describe the stretching force that moved exercises on all space and time which it encounters," said David Nichols, Caltech of graduate of student from one who came with the term "Tendex." says. "Tendex lines sticking out of the Moon raise would apart the tides on Earth oceans and the stretching force of these lines an astronaut ribs, falling into a black hole."

Describe Vortex lines, on the other hand, the twisting of space. So, if an astronaut body with a vortex line is, it would get abgepresst like a wet towel.

She tried the tools specifically on computer simulated black hole collisions and saw that ring-shaped Vortex would lead such impact lines, flying from the merged black hole like smoke rings. The researchers found that a bunch of vortex lines spiral from the black hole such as water from a rotating sprinkler. Depending on the angles and speeds of the collisions, lines - or gravitational waves - Vortex and Tendex would behave differently.

"Although we have developed these tools to black hole collision, they are applied can anywhere where space and time has moved," says Dr. Geoffrey Lovelace, a member of the team of Cornell. "For example, I expect that people Vortex and Tendex are lines cosmology, black holes tear stars rated, and singularities in black holes life." "You will become standard tools in the entire general theory of relativity."

The researchers say that the rows are Tendex and vortex a powerful new way to understand the nature of the universe. "By using these tools we now can make much better sense of the enormous amount of data that are produced in our computer simulations," says Dr. Mark Scheel, a senior researcher at Caltech and leader of the simulation of teamwork.

Their paper was published in the April 11 in the physical review letters.
