These two pie charts clearly show that the ratio dark matter / normal matter is bigger today than it was in the past.
But why? How is it possible?
And does it mean that the amount of dark matter increased or that the amount of normal matter decreased?
The only explanation that I could come up with is that there are extra dimensions and dark matter contrary to normal matter can freely move in these extra dimensions. So dark matter outside our 3D universe came inside our universe, which made the amount of dark matter in our universe increase.
