NASA SDO - Lovely Loops

The Lovely Loops A close-up view of the Sun's edge shows vast loop structures made of superheated plasma, just one of which is the size of several Earths. These loops can have a wide range of temperatures, many reaching several million degrees Kelvin. The upper one of a pair of new, solar active regions that just rotated into view offered a beautiful profile view of those cascading loops spiraling above it (Jan. 15-16, 2012) following a solar flare eruption. With its ability to capture the Sun in amazing detail, SDO observed it all in extreme ultraviolet light. This particular video clip used an image every minutes to present the motion.

Loop quantum gravity 01

A lecture from the CERN website by Carlo Rovelli (who initially introduced the theory of loop quantum gravity in 1988). Date- 21.08.2008. Source- http://cdsweb.cern.ch/record/1121957?ln=en slides- http://indico.cern.ch/getFile.py/access?contribId=30&resId=0&materialId=slides&confId=21917 From wiki- 'Loop quantum gravity (LQG), also known as loop gravity and quantum geometry, is a proposed quantum theory of spacetime which attempts to reconcile the theories of quantum mechanics and general relativity. It preserves many of the important features of general relativity, while at the same time employing quantization of both space and time at the Planck scale in the tradition of quantum mechanics. The technique of loop quantization was developed for the nonperturbative quantization of diffeomorphism-invariant gauge theory. Roughly, LQG tries to establish a quantum theory of gravity in which the very space, where all other physical phenomena occurs, becomes quantized.'
