And also, he said, okay, if the universe is expanding now what if we just look back.

But in that sense, universe will always look the same, keep expanding but always look the same.

Now, if we look at the background universe, which continues expanding, its density go, keeps going down.

You may remember that energy is not conserved in an expanding universe. Well, here is an obvious case.

And it has the well familiar solution of universe expanding at time, it's time to the third power.
