Why Time Might Not Be an Illusion
Einstein’s relativity pushes physicists towards a picture of the universe as a block, in which the past, present, and future all exist on the same footing; but maybe that shift in thinking has gone too far.

The Complexity Conundrum
Resolving the black hole firewall paradox—by calculating what a real astronaut would compute at the black hole's edge.

Quantum Dream Time
Defining a ‘quantum clock’ and a 'quantum ruler' could help those attempting to unify physics—and solve the mystery of vanishing time.

Our Place in the Multiverse
Calculating the odds that intelligent observers arise in parallel universes—and working out what they might see.

Sounding the Drums to Listen for Gravity’s Effect on Quantum Phenomena
A bench-top experiment could test the notion that gravity breaks delicate quantum superpositions.

Please continue this great work and I look forward to more of your awesome blog posts.

Dear Physicists,

Only Nature could provide the simplest reality. The real visible Universe must consist only of a unified infinite surface occurring in one infinite dimension that am always illuminated by infinite non-surface light.

The physicists claim that the strongest evidence for there having been a finite commencement of the universe was their belief that the “(complex) laws of Physics are universal and don’t change with time and location in space.”

You do...

:) it is fqxi which merits these thanks, me I just share this information.

Regards jedi of the SPHERE :)
