The current theoretical model for the composition of the universe is that it's made of normal matter, dark energy and dark matter. A new University of Ottawa study challenges this.
Coles notes: scientists made calculations on the universe and it didn’t make sense because the math says there should be more mass and energy than what they know exists. So they called the missing mass dark matter and the missing energy, dark energy.
Now some guy in Ottawa figured out better math that doesn’t need the “dark” stuff to make the math make sense.
My understanding of dark energy is a little different. As I understand it, we figured gravity pulls things together, right? So everything should be kinda slowly falling back together from the big bang. It was theorized to end in a ‘big crunch’ where the universe collapses back and then explodes again in a cycle.
Only when they tried to measure how fast distant objects were moving relative to us, they found that things were still moving away from each other. More than that, the farther away things were, the faster they were moving. Meaning distant objects were accelerating.
Acceleration requires energy, but we don’t know the mechanism behind this, or where the energy comes from. Hence, dark energy.
kinda, dark energy is the unknown explanation for the expansion of the universe. Once we understand it enough to know what it is responsible for it’ll no longer be dark.
You humans and your primitive knowledge. The rest of the universe knows that this dark energy you haven’t found out yet is called Mana and allows miracles to be made. /S

Maybe, we don’t know.
Just to be clear, there are lots and lots of different observations that are all explained by dark matter; it’s not just a single term in “the math”. Furthermore, the hypothesis presented in this article is not “better math” because it does not do as good a job as dark matter in explaining all of these observations.
