You are kind of proving my point though. With fog, you can see the laser because photons are bouncing off the fog and hitting your eye. This article isn't saying that photons are bouncing the magnetic fields and then hitting their eyes, they are saying the eyes can literally detect magnetic fields. If the birds were seeing magnetic fields via how they interact with photons, then everyone would be able to 'see' magnetic fields because we can all see photons. This is saying that the magnetic fields are directly visible by birds.
- mygo 9y agoI’m aware that photons have to physically interface with the retina to be seen. You’re missing my point. Earth’s atmosphere acts like the fog as a laser travels through it — it diffuses the vectors, making them visible to an observer not along the path from the light source. When you look up at the clear sky during the day you don’t see the sun and then pure black space (and stars). Likewise the effects of the magnetic field interface with earth’s atmosphere. For example Earth's magnetic field deflects solar wind. The solar wind interacting with the magnetic field transfers some of its energy into earth’s atmosphere.
