Purifying Physics: The Quest to Explain Why the “Quantum” Exists
A new framework for the laws underlying reality could explain why nature obeys quantum rules, the origin of time’s arrow, and the power of quantum computing.

Searching for the Impossible
A quest to discover which computational tasks can never be resolved.

Six Degrees to the Emergence of Reality
Physicists are racing to complete a new model of "quantum complex networks" that tackles the physical nature of time and paradoxical features of emergence of classical reality from the quantum world

Quantum in Context
An untapped resource could provide the magic needed for quantum computation—and perhaps even open the door to time travel.

Spot the Difference to Reveal Exotic Particles
Questioning the symmetrization postulate of quantum mechanics and the notion that electrons are indistinguishable could reveal whether hypothetical new particles exist.

The radio signals most likely to be detectable would be those emitted by scientific probes or even communications between space ships (for space traveling civilizations).

Such signals would of necessity have more power behind them and thus be more likely to be detectable over long distances. Normal intraplanatary communications only need sufficient power to travel at most a distance measured in kilometers. Communications to distant probes need power and frequencies that can travel...
