I was told here that light didn't have an attractive/repulsive force (charge)?

Light by light scattering does not occur only at tree level. Basically, you can have the photons fluctuating simultaneously into two fermion pairs. That forms a closed loop (box) diagram. It's quite interesting and challenging.

Thanks humanino.
Sorry I didn't realize you were answering my question until I looked up what a fermion was.
 

FAQ: Does Light Have a Charge? Mystery Explored

What is light charge?

Light charge is a term used to describe the electric charge of photons, which are the fundamental particles of light. This charge is extremely small and is often considered to be zero.

How is light charge measured?

Light charge is measured using a device called a photon counter, which can detect individual photons and measure their energy. The results are then used to calculate the electric charge of light.

What is the significance of understanding light charge?

Understanding light charge is crucial in many areas of science, including quantum mechanics and electromagnetism. It helps us understand the behavior of light and its interactions with matter.

Can light charge be manipulated?

Yes, light charge can be manipulated through various methods such as using electric and magnetic fields. This is important in technologies such as lasers and optical communication systems.

Why is the mystery of light charge important?

The mystery of light charge has been a topic of scientific interest for decades. Solving this mystery can lead to a better understanding of the fundamental nature of light and could potentially lead to new technologies and applications.
