Australia’s Quantum Battery Turns a Strange Idea Into Electricity
An Australian quantum battery prototype can charge, briefly store energy and deliver electrical output. Its most intriguing feature is what happens as more units work together.

Australia’s Next Big Battery Could Be Two Reservoirs on a Hill
A proposed NSW project would store electricity by pumping water uphill, then release it to deliver power for ten hours. Wala Wala shows why gravity still has a place in the battery race—and why the hardest questions are about the land, water and construction.

Time Travel Is Real—But Only in One Direction So Far
Physics already lets clocks and people move into the future at unequal rates. Travelling backwards is far stranger: some equations permit it, but nature has supplied no wormholes, time loops or messages from tomorrow.

NuScale vs Oklo: Two Very Different Routes to Small Nuclear Power
NuScale is pursuing a regulator-approved light-water module for multi-reactor plants. Oklo is developing smaller sodium-cooled powerhouses that it plans to own and operate. Here is what each company has actually achieved—and what remains unproven.

Can Anti-Gravity Ever Be Real? What Physics Actually Allows
Antimatter falls down, magnetic fields can levitate living tissue, and astronauts float while still under Earth’s pull. Here is where anti-gravity science ends and imitation begins.
