"It turns out that roughly 68% of the universe is dark energy. Dark matter makes up about 27%. The rest - everything on Earth, everything ever observed with all of our instruments, all normal matter - adds up to less than 5% of the universe."

Imagine waves of spacetime, like the surface of an ocean. The waves are typical, with peaks and troughs. But these are very big waves. The waves are so big that whole galaxies can fall into the troughs between each peak. The total mass-energy equivalence of the troughs is equal to the mass of ordinary matter (5 percent), plus the equivalent mass of the trough itself (27 percent). The total is 32 percent of the mass-energy of the universe. The mass-energy equivalence of the peaks is 68 percent. The equation representing this ratio is:

y = sin(x) + 0.235

To get these ratios, all you have to do is find the area under the curve represented by the trough and peak. The area under the trough is the sum of dark and ordinary matter. The area under the peak corresponds to dark energy.

So... both dark energy and dark matter are described as the peak and trough of a simple sine wave, vertically translated by 0.235.

The equation of the universe is incredibly simple.
