Scientists proposed a model in which the mysterious force (dark energy) possesses something like inertia: it needs time to respond, like a heavy pendulum. Because of this, the expansion of the Universe doesn’t accelerate forever, but instead decays, like a pendulum in thick honey.

The birth of the universe is often compared to inflating a balloon: in the first moments, it stretched rapidly. But the very "rubber" of this balloon was probably not perfectly smooth — rather, it was covered with the finest ripples.
