Dark Matter
We came up as a species not understanding a lot of science. Just making fire was considered a breakthrough. However, as we grew more and more intelligent, we began to understand more and more. It led to advancements in multiple fields, from healthcare to technology. We then perfected those concepts and made them better while continuing to learn and advance.

Therefore, when you consider all we’ve done in human history, it’s a lot to hear about “matter” itself. The planets and stars are all part of the normal matter that we can not only see but comprehend when it relates to those outside our own galaxy too. Yet all of the matter we know to be normal makes up roughly 5% of all known matter. Dark matter makes up 85% of all matter in the universe.
