Dark Energy will possibly always be something that lands in the area of science rabbit holes. Even scientists claim it is literally “an unknown form of energy” that af
fects the universe on extremely large scales. We actually did not even know it existed and found out by accident. Scientists discovered it when measuring supernovae. They found that the universe does not expand at a constant rate, but rather, the universe is expanding at an accelerated rate.
Before this, we did not know a lot of things. We tend to think, as humans, that we know more than we do. However, the discovery of dark energy proved how ignorant we truly were without realizing it. Before its discovery, we only knew of regular matter and dark matter, along with radiation.
