The rise of fascism shaped Schrödinger’s cat fable.
Quantum entanglement is thought to be one of the trickiest concepts in science, but the core issues are simple. And once understood, entanglement opens up a richer understanding of concepts such as the “many worlds” of quantum theory.
And you thought there were just solids, liquids, gases and plasma
The laws of physics work both forward and backward in time. So why does time seem to move in only one direction? One potential answer may also reveal the secrets of the universe’s missing mass.
Alan Alda and Brian Greene discuss Einstein's relationship with the "unruly child" of quantum mechanics. Einstein founded the field in 1905, and then spent his life searching for a theory that would supercede it.
If you jump into a black hole, your mass energy will be returned to our universe but in a mangled form which contains the information about what you were like but in a state where it can not be easily recognized. It is like burning an encyclopedia. Information is not lost, if one keeps the smoke and the ashes.
The Standard Model is a physical theory of a spectacularly successful sort. It is built on beautiful and deep mathematics, covers almost all known physical phenomena, and agrees precisely with the result of every single experiment ever done to test it. It leaves open a very small number of questions: why this specific combination of groups? What determines the parameters of the model? What about gravity? Does it need to be extended to account for dark matter?
