Are there forces around us that are invisible, for example, magnetism? Are there aspects of matter that are ‘invisible’ or not visible to the naked eye? What would the world be like if you could see such forces or such aspects of matter?

Yes, the forces like magnetic, gravitational, electric, etc. are present around us which are invisible. We can feel these forces but cannot see. It is existence of such forces which has help the planets, stars, galaxies, etc. in their respective position. Due to gravitation force, things always fall to the Earth. In the absence of these forces, we would have been floating in the atmosphere. Some heavenly bodies can be seen with the help of naked eyes, while there are some stars which cannot be seen with the help of naked eyes.
If we could see such forces, the world would be seen surrounded by various rays which will be crossing each other like a maze. The confusion will be so great that one will not be able to understand which path to follow or which is restricted.
