Physicists develop new theory to answer fundamental questions about black holes

When stars collapse, they can create black holes, which are everywhere throughout the universe and therefore important to be studied.

Illinois engineers protect artifacts by graphene gilding

Gilding is the process of coating intricate artifacts with precious metals. Ancient Egyptians and Chinese coated their sculptures with thin metal films using gilding--and these golden sculptures have resisted corrosion, wear, and environmental degradation for thousands of years.

Study reveals the Great Pyramid of Giza can focus electromagnetic energy

An international research group applied methods of theoretical physics to investigate the electromagnetic response of the Great Pyramid to radio waves.

Taming the multiverse: Stephen Hawking’s final theory about the big bang

The theory, which was submitted in collaboration with Professor Thomas Hertog from KU Leuven for publication before Hawking’s death earlier this year, is based...

Scientists calculate radiation dose in bone from victim of Hiroshima bombing

The bombing of the Japanese cities Hiroshima and Nagasaki by the United States in 1945 was the first and only use of nuclear weapons against civilian targets.

Underground neutrino experiment sets the stage for deep discovery about matter

If equal amounts of matter and antimatter had formed in the Big Bang more than 13 billion years ago, one would have annihilated the other upon meeting, and today's universe would be full of energy but no matter to form stars, planets and life. Yet matter exists now.

New confirmation of Einstein’s General Theory of Relativity

Albert Einstein predicted that whenever light from a distant star passes by a closer object, gravity acts as a kind of magnifying lens, brightening and bending the distant starlight. Yet, in a 1936 article in the journal Science, he added that because stars are so far apart "there is no hope of observing this phenomenon directly."

‘Ghost particles’ could improve understanding the universe

Trillions of neutrinos, or ghost particles, are passing through us every second. While scientists know this fact, they don't know what role neutrinos play in the universe because they are devilishly hard to measure.

Theory that challenges Einstein’s physics could soon be put to the test

Scientists behind a theory that the speed of light is variable – and not constant as Einstein suggested – have made a prediction that could be tested.
