Eternal clock proposed

4D Space-time Crystal A 4D space-time crystal, researchers say, could run a clock that would be able to keep time forever.

From the article:

“…the scientists would aim to create a ring of charged particles, with the resulting electromagnetic forces causing the structure to rotate perpetually. At its lowest quantum-energy state, also known as its ground state, the system has no disorder, or entropy, and there is no way for its entropy to increase over time. Thus, the crystal’s temporal structure and timekeeping ability would continue even after the universe reached a state of ‘heat death,’ also known as thermodynamic equilibrium, when it had devolved into entropy.”

The clock would apparently keep time even after the universe itself has ceased to exist.

Warp drive more feasible than previously thought

Warp Drive StarshipA ‘warp drive’ to achieve faster than light travel may not be as unrealistic as previously thought (early calculations determined that such a device would consume prohibitive amounts of energy). Physicists now say “that adjustments can be made to the proposed warp drive that would enable it to run on significantly less energy, potentially bringing the idea back from the realm of science fiction into science.”
