Spacetime. Tiny elements create bizar universes.

Thimothy Budd, of the Niels Bohr Institute (NBI) of Copenhagen University, does research on models of quantum grafity. He tries to find connections between microscopic models of space-time and Einstein’s classical theory of general relativity. The pictures represent the development of space and time according to special mathematical computations. From one startingpoint tiny elements of spacetime, …

Outbursts of the Sun better understood with new pictures

New high res pictures of the Big_Bear_Solar_Obsevatory in California show how sunspots arise from flares. Very detailed observations of scientists of the New Jersey Institute of Technology are presented at the 224th meeting of the American Astronomical Society in Boston. The 1,6-meter New Solar Telescope (NST) has made the sharpest pictures of the sun ever, by compensating …
