Okay so I've been searching the internet for this answer, but I have not yet found it. What is dark matter/dark energy? What is the difference between the two? On a website that I was on earlier, someone described dark matter as a cluster of dark energy, which would make no sense because matter has mass and takes up space. I also learned that it's what holds galaxies together with gravity (theoretically), but energy has no mass so it cannot have a gravitational pull. Another thing I was wondering was if it is a solid, liquid, or gas? Or maybe something completely different? If dark matter makes up most of the universe... Why can't we find any? Thank you for answering this and sorry if I seem dumb.
