Light --> matter<quoted text>There are many things we have not explained. That doesn't mean they cannot be explained. In fact, many things were once thought impossible to explain that have actually been explained. What makes you think the things you are thinking about *cannot* be explained? Can you give an example?
Einstein's discovery of the law of photoelectric effect and E=MC2. There are explanations to them.
But no explanation how light affected matter in the beginning of time when matter was formed. Like I said poly, I have such imagination. lol
