“This has been happening ever since I realized how often it feels as though I know something just because I can find it with Google. Technically, of course, I don’t know it. But when there’s a smartphone or… read more

Big Bang or Big Chill? The ‘Quantum Graphity’ theory

Is this the hidden granular structure from lensing-like effects? (Credit: James Q. Quach et al./

The start of the Universe should be modeled not as a Big Bang but more like water freezing into ice, according to a team of theoretical physicists at the University of Melbourne and RMIT University.

They suggest that by investigating the cracks and crevices common to all crystals — including ice — our understanding of the nature of the Universe could be revolutionized.

New NASA data challenges global warming theory

July 29, 2011

Particles in upper atmosphere slow down global warming, says NASA (credit: NASA)

NASA satellite data show the Earth’s atmosphere is allowing far more heat to be released into space than current computer models have predicted, according to a new study in the peer-reviewed science journal Remote Sensing.

Data from NASA’s Terra satellite shows that when the climate warms, Earth’s atmosphere is apparently more efficient at releasing energy to space than models used to forecast climate change have been programmed to… read more
