**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.

**Watching the Observers**

Accounting for quantum fuzziness could help us measure space and time—and the cosmos—more accurately.

Spacetime Squids

Quantum physicist Sorin Paraoanu talks about building an artificial spacetime in the lab from SQUIDs--to test inflation and quantum gravity. In this extended interview he also talks testing the Landau-Zener formula beyond its limits and amplifying the vacuum. Recorded at the quantum foundations meeting in Erice, Italy, sponsored by COST.

a bridge in geometrical algebras ???? :)

all my net is checked even here ....for the prize in algebras ??? It is not cool in fact , I have seen the nobel prize in maths .what is this story ??? Perhaps Mr Tyson and Tegmark can explain me ??? I am not parano I know just the human nature but I am christian also, so I can pardon .... respect me and I will respect you .
