A new experiment shows that two observers can experience divergent realities (if they go subatomic).
- In 1961, Nobel Prize-winning physicist Eugene Wigner proposed a thought experiment by which the reality of two observers can diverge by measuring a single photon.
- Researchers recently tested Wigner's thought experiment and concluded that realities can be made irreconcilable.
- Do these results put the entire scientific method at risk? Let's not get ahead of ourselves.
Do you have a magnetic compass in your head?
Sounds wild, but it may well be so.
- Birds' navigation using Earth's very faint magnetic fields suggests an incredible level of sensitivity.
- There's reason to think that sensitivity may be based on quantum entanglement in cryptochrome in their eyes.
- Identifying the role of quantum physics in biology could lead, well, who knows where?
It's all about holding on to the heat you have.
Whether waiting for a bus, playing outside or walking the dog – during the colder winter season, everyone is looking for ways to stay warm. Luckily, the process your body uses to break down foods serves as an internal heater.
On Friday, NASA's InSight Mars lander captured and transmitted historic audio from the red planet.
- The audio captured by the lander is of Martian winds blowing at an estimated 10 to 15 mph.
- It was taken by the InSight Mars lander, which is designed to help scientists learn more about the formation of rocky planets, and possibly discover liquid water on Mars.
- Microphones are essentially an "extra sense" that scientists can use during experiments on other planets.
