Dissolving Quantum Paradoxes
The impossibility of building a perfect clock could help explain away microscale weirdness.

Constructing a Theory of Life
An all-encompassing framework of physics could help to explain the evolution of consciousness, intelligence, and free will.

Usurping Quantum Theory
The search is on for a fundamental framework that allows for even stranger links between particles than quantum theory—which could lead us to a theory of everything.

Fuzzballs v Black Holes
A radical theory replaces the cosmic crunchers with fuzzy quantum spheres, potentially solving the black-hole information paradox and explaining away the Big Bang and the origin of time.

Whose Physics Is It Anyway? Q&A with Chanda Prescod-Weinstein
Why physics and astronomy communities must take diversity issues seriously in order to do good science.

A Cosmic Test for Time
A solar-system-sized experiment to test the nature of time: is time malleable, as general relativity suggests, or uncertain, as quantum mechanics asserts? SETI scientist Laurance Doyle describes his plans to bounce radar from the moons of Jupiter to reporter John Farrell.

Existential Risk
Nick Bostrom of the Future of Humanity Institute assesses the risks of a global catastrophe that could wipe out life, either from natural or human-induced environmental disasters or machine intelligence, synthetic biology, or nanotechnology that has got out of hand. With reporter Carinne Piekema.

Yes : ), I have never tried the computer screen thing but I will take your word for it.

Steve and Georgina,

Colors, like "red", cannot be measured at all; they are purely subjective responses to the objective properties of light. The best that we can do is measure properties like amplitudes and frequencies, and then deduce, rather than measure, that a normal human visual system, will produce the perception of the color, in response to those objective properties.

The difference is important. When you see the color yellow, on your computer screen, you are not "seeing"...


RE: "The Pound-Rebka experiment is compatible with Newton's emission theory of light", and "in general relativity, the speed of light falling towards the source of gravity idiotically DECREASES (in the gravitational field of the Earth the acceleration of falling photons is NEGATIVE, -2g)"

Have you actually read the paper? If you have not go to the second to the last paragraph and study the Plus and Minus signage before talking of compatibility or not with...
