Light bending around neutron and bound photon

In summary, the neutron is a particle with finite size and is a single particle without any further structure or components, like a nucleus. It is also electrically neutral. The neutron has a rest mass similar to that of a hydrogen atom and is approximately the size of a nucleus. When a photon interacts with a neutron, it is attracted by the mass of the neutron, but this gravitational attraction is too weak to bind the photon. There is also a magnetic force between the two, but this is also too weak to bind the photon. The paper gr-qc/0412064 discusses this topic further. The neutron-photon interaction can result in interesting consequences, but it is not strong enough to affect space-time. There are ways to access the

I assume that the neutron is a particle with finite size and is <really> a single particle (that is that it does not have any further structure or components-like nucleus) and lastly it is electric nutral. I hope that these assumptions are close to the experimental observations. I am making life simple by not assuming subatomic particles or gluons etc.

We know tht a neutron is a fairly heavy particle with rest mass of about that of hydrogen atom and the size is as small as the nuclus (Fermi). Consider that a photon interacts with a nutron. As the photon gets attracted by the mass of nutron, it should feel a central force field. It is likely that this filed shuld trap the photon.

If that doesn't happen, why does that not happen?

If that happens, what happens to the space time? It should result in a number of interesting consequences. I wish the readers to enumerate them. (Is every neutron a black hole?)

The gravitational attraction between a photon and a neutron is much too weak to measure, much less bind the photon.
There is a magnetic force between a photon and a neutron due to the neutron having a magnetic moment. This interaction is also much too weak to bind the photon, but is observed in scattering of a photon by a neutron.

that's a paper index for arxiv.org. google it for example.
 

1. How does light bend around a neutron and bound photon?

Light bends around a neutron and bound photon due to the warping of space-time caused by their mass. This bending is known as gravitational lensing and was first predicted by Einstein's theory of general relativity.

2. What is the significance of light bending around these particles?

The bending of light around a neutron and bound photon allows us to study and observe these particles, which are otherwise invisible to us. It also confirms the validity of Einstein's theory of general relativity.

3. Can light bend around other particles besides neutrons and bound photons?

Yes, light can bend around any massive object. However, the amount of bending depends on the mass of the object. The greater the mass, the greater the bending of light.

4. How is light bending around neutrons and bound photons observed?

Light bending around these particles can be observed through telescopes, where the bending causes a distortion or magnification of the image of a background object. This effect can also be seen during astronomical events such as solar eclipses.

5. What implications does light bending around particles have for our understanding of the universe?

The phenomenon of light bending around particles provides evidence for the existence of dark matter, which is thought to be responsible for the majority of the gravitational lensing observed in the universe. It also helps us to better understand the structure and dynamics of the universe.
