Does mass really exist or is it just a property of energy?
That's mind-boggling to think about. How does this relate to the concept of dark matter?
Dark matter is a hypothetical form of matter that doesn't interact with light or other forms of electromagnetic radiation. It's postulated to exist based on its observed gravitational effects on visible matter. Scientists believe that dark matter is five times more abundant in the universe than visible matter, and it's thought to play a crucial role in the structure and evolution of the universe.
