The famous fish doorbell season is back! How to help
- In Utrecht, Netherlands, fish are swimming upstream to their spawning grounds but are prevented from reaching their destinations due to a boat lock.
- To assist the fish, a live stream camera has been set up at the boat lock. Viewers can ring the doorbell when they spot a fish, which alerts the lock operator to open the lock and allow the fish to swim through.
- The quicker the fish are able to pass through the lock, the higher their chances of survival as they are vulnerable to predators while waiting.
- By participating in the fish doorbell project, viewers can contribute to improving water quality and freshwater marine life in the canals of Utrecht.

How the Spatial Oscillation Model Replaces Time
- Time is not a fundamental quantity, but a derived concept from spatial oscillations.
- 1 OSC (one spatial oscillation) is the distance light travels in the time of one oscillation of a cesium atom.
- Physics can be entirely rewritten in terms of spatial oscillations instead of time.
- Time dilation is a shift in spatial oscillations, not a fundamental effect.

New telescope captures stunning images of baby planets
- Astronomers at the University of Arizona have captured stunning images of young planetary systems using the Magellan Adaptive Optics Xtreme (MagAO-X) telescope.
- MagAO-X, with its adaptive optics system, provides clear and sharp images of planets forming around the young star PDS 70, located 370 light-years away.
- Key discoveries include dust rings surrounding the planets, which are expected to collapse and form moons, and significant changes in brightness believed to be caused by variations in hydrogen gas falling onto the planets.
- Studying these young planets can help scientists understand the formation and evolution of our own solar system.

Gravity from Entropy: Breakthrough Theory Links Quantum Mechanics and Relativity
- Recent research proposes a framework linking gravity to quantum relative entropy, bridging quantum mechanics and general relativity.
- By treating spacetime as a quantum system, this approach offers new insights into black holes, dark matter, and the fabric of the universe.
- The model introduces the G-field, a Lagrangian multiplier enforcing constraints on matter-induced metrics affecting spacetime curvature.
- It predicts a small cosmological constant, aligning with the universe's accelerated expansion, and offers a natural connection between classical and quantum physics.
- Unlike discrete gravity models, this continuum approach maintains Lorentz invariance and combines principles of quantum field theory.
- The theory sidesteps challenges of describing spacetime at microscopic scales, leveraging tools from quantum information theory.
- By building gravity from entropy, the model may explain black hole thermodynamics and the preservation of information in extreme gravitational environments.
- The hypothesis suggests spacetime curvature emerges from quantum principles, potentially reshaping theories of the early universe and gravitational waves.
- Future research will test the model's predictions and explore implications for dark matter, black hole thermodynamics, and quantum information science.
- If successful, this approach could revolutionize physics by offering new insights into the fundamental forces governing the universe.
