Experiment confirms quantum theory weirdness
The bizarre nature of reality as laid out by quantum theory has survived another test, with scientists performing a famous experiment and proving that reality does not exist until it is measured.
Explainer: How do satellites orbit the Earth?
Take a look at the moon and it isn't hard to imagine it as a planet. A 3,476 kilometres-in-diameter ball of rock, with basalt plains and mountain ranges, whose gravitational pull produces tides here on Earth.
Should your driverless car kill you to save a child's life?
Robots have already taken over the world. It may not seem so because it hasn't happened in the way science fiction author Isaac Asmiov imagined it in his book I, Robot. City streets are not crowded by humanoid ...

Can light orbit a black hole?
Since black holes are the most powerful gravitational spots in the entire Universe, can they distort light so much that it actually goes into orbit? And what would it look like if you could survive and follow ...
Beyond the Higgs boson: Five reasons physics is still interesting
Would physics be "far more interesting" if the Higgs boson had not been found? Stephen Hawking thinks so. He made this bold claim, possibly with his tongue slightly in his cheek, at the opening of a new ex ...
Extending Einstein: Researchers demonstrate a new kind of quantum entanglement
Physicists at the University of Calgary and at the Institute for Quantum Computing in Waterloo have published new research in Nature Physics which builds on the original ideas of Einstein and adds a new ingredient: a thir ...
Physicist suggests Einstein could have beaten Bohr in famous thought experiment
Quantum cats are hard to see
Are there parallel universes? And how will we know? This is one of many fascinations people hold about quantum physics. Researchers from the universities of Calgary and Waterloo in Canada and the University ...
Researchers consider ancestry of recent fossil finds
(PhysOrg.com) -- Someday a future intelligent organism could sweep away a million years of dust and find the bones of a Homo sapiens and wonder what he was.
