What if the Universe was in fact a simulation? A product of some information processor, creating space and time, energy and matter? What if the Big Bang was the whole simulation booting up, beginning billions of years of space and time calculations? Can we possibly understand our consciousness as a subroutine in an advanced number crunching machine? A new paper published by the Centre for Discrete Mathematics and Theoretical Computer Science, University of Auckland, asks us to keep an open mind and suggests if we look at the complexity of physical laws of our known universe, many paradoxes may be explained if we view our physical reality as a virtual reality.

Hinode Discovers the Sun’s Hidden Sparkle

Blinking spots of intense light are being observed all over the lower atmosphere of the Sun. Not just in the active regions, but in polar regions, quiet regions, sunspots, coronal holes and loops. These small explosions fire elegant jets of hot solar matter into space, generating X-rays as they go. Although X-ray jets are known to have existed for many years, the Japanese Hinode observatory is seeing these small flares with unprecedented clarity, showing us that X-ray jets may yet hold the answers to some of the most puzzling questions about the Sun and its hot corona.
