A View From the Top
Thinking of causation as a "two-way street"—along which the passage of information can be inverted—could have implications for the origin of life.
Classic Article: Black Holes, Paradox Regained
In 2004, Stephen Hawking famously conceded that black holes do not devour all information when they swallow matter—seemingly resolving the "black hole information paradox" that had perplexed physicists for decades. But some argue that the paradox remains open, and we must abandon our simple picture of spacetime to unravel it.
Quantum Biology: Making Waves in the Natural World
Could quantum effects explain the mechanisms behind smell, photosynthesis and bird navigation?
The Accidental Universe
Have we been fooled into seeing one form of reality, with particular fundamental forces and laws, based on the peculiar way that we have chosen to measure time?
The Cosmic Hologram
Is our universe an illusion projected backward in time from the future?

So these two men get along well and enjoy a cup of coffee together. This article took a long while to get going but in the end was quite interesting.
I agree that there are problems with mathematics but to throw logic out of the door to fix it sounds a bit extreme. If it just boils down to making the mathematics more flexible that is a different matter but picking and choosing when to be flexible and when not is a bit arbitrary.It doesn't sound right to just pick the mathematics that...

Physics postulates isotropic vacuum for Einstein's elevator (GR) and angular momentum conservation (QFT) through Noether's theorem. Parity is the only non-Noetherian external symmetry. Physics choked on parity (Yang and Lee). Any symmetric body gaplessly dissects into homochiral halves (La Coupe du Roi; Ashtekar and GR). Quantized gravitation is not predictive. Therefore...
