Neither does it try to explain what.

Since light takes time to travel, the farther out into space we look, the further back in time we see. When we flip a switch, the light from the light bulb reaches us in a few nanoseconds (a billionth of a second), but sunlight is 8 minutes old, light from nearby stars has taken.

Perhaps unsurprisingly, our universe has just the right mass-energy density, equivalent to about 5 protons per cubic metre, which has allowed it to expand for the last 13.8 billion years, giving time to form the universe as observed today. There are dynamical forces acting on the particles in the universe which affect the expansion rate. Before 1998, it was expected that the expansion rate.
