Like what are the chances that dark matter can be described with electromagnetism instead?

I confess that this statement might have it's own flaws, but it manages to answer your question. If not satisfied with this one, just the second resource found by google (search for "dark matter" naturally) says:Dark matter is called dark because it does not appear to interact with observable electromagnetic radiation, such as light, and is thus invisible to the entire electromagnetic spectrum, making it extremely difficult to detect using usual astronomical equipment.

This means it does not absorb, reflect or emit light, making it extremely hard to spot. In fact, researchers have been able to infer the existence of dark matter only from the gravitational effect it seems to have on visible matter.
You seem to be asking, "can the effects attributable to "dark matter" be due to some sort of electromagnetic process instead?", am I right? A reasonable assumption, however very tricky observations of the splitting of spectral lines finds that the magnetic fields of galaxies are very, very weak, so unfortunately this idea doesn't seem to be supported by observations.Blinked said:Like what are the chances that dark matter can be described with electromagnetism instead?
None. The motion described by dark matter is measured by the light from stars. Bulky objects like planets and stars do not hold much electric charge per unit of mass.Blinked said:Like what are the chances that dark matter can be described with electromagnetism instead?
The electromagnetic force does not directly affect the motion of stars in a galaxy. Gravity is the dominant force that governs the motion of celestial bodies in a galaxy. However, the electromagnetic force does play a role in the formation and evolution of galaxies through its interaction with matter and radiation.
Yes, the electromagnetic force can indirectly cause galaxies to collide. When two galaxies come close to each other, their gravitational attraction causes them to interact and eventually collide. During this process, the electromagnetic force plays a role in the heating and ionization of gas particles, which can lead to the formation of new stars.
The electromagnetic force does not directly influence the shape of a galaxy. The overall shape of a galaxy is primarily determined by its mass distribution and the gravitational forces acting on it. However, the electromagnetic force can affect the gas and dust within a galaxy, which can contribute to the formation of structures such as spiral arms.
No, the rotation of a galaxy is mainly due to the conservation of angular momentum, which is a property of all objects in motion. The electromagnetic force does not directly contribute to the rotation of a galaxy, but it can influence the motion of gas and dust particles, which can affect the overall rotation of a galaxy.
Yes, the electromagnetic force can play a significant role in the rate of star formation in a galaxy. It can compress gas clouds, triggering the collapse and formation of new stars. It can also affect the temperature and density of gas, which can impact the conditions necessary for star formation to occur.
