Beyond energy, matter, time and space

New particles may yet be discovered, and even new laws. But it is almost taken for granted that everything from physics to biology, including the mind, ultimately comes down to four fundamental concepts: matter and energy interacting in an arena of space and time. (Credit: Carl Wiens)

‘Quantum Bounce’ theory claims black holes explode

Kepler's Supernova Remnant "On October 9, 1604, sky watchers -- including astronomer Johannes Kepler, spotted a "new star" in the western sky, rivaling the brilliance of nearby planets. "Kepler's supernova" was the last exploding supernova seen in our Milky Way galaxy.

Physicists succeed in revealing the scaling behaviour of exotic giant molecules

According to Efimov's prediction, bound states of three atoms can be universally described under certain conditions. The scientist found that infinitely many quantum mechanical bound states for the "ménage à trois" exist, even if two of the atoms cannot bind together.

Let me ask you this: ‘Are bananas radioactive and is it true that eating too many can kill you?’

Yes, you will certainly die from radiation poisoning if you are able to eat 10,000,000 bananas at once. You may also witness chronic symptoms if you eat 274 bananas a day for seven years. — Yes, you will certainly die from radiation poisoning if you are able to eat 10,000,000 bananas at once.
