They won't see cosmic background radiation, and they won't be able to learn about the Big Bang.

In a process called cosmic inflation, the observable universe expanded rapidly, from the size of a marble to trillions of kilometers, in a trillionth of a second.

Instead, astronomers use the Cosmic Microwave Background, or CMB, an echo of the early universe, which involves low-energy photons bouncing around everywhere in all directions, all the time.

We’ve once again attempted to find a respite from cosmic alienation and failed.

So things that are close and are very massive are more attractive, winning the cosmic tug-of-war.

In today's universe, only the most violent cosmic events can create the necessary conditions, such as the merger of neutron stars or when the core of a very massive star collapses in a supernova.
