Why do popular science news keep offering new theories about the basic shape of our universe every week?

Planck has given us more precise measurements of how the universe works, but mostly confirms what we know.

For inflation to remain cosmology's top theory of how the universe grew into what we see today, we need to find the right gravitational waves in experiments ramping up to do just that.

Penrose and Gurzadyan respond to their critics without offering anything new for the debate.

Roger Penrose thinks he discovered traces of previous Big Bangs in the Cosmic Microwave Background Radiation, but his evidence for it seem thin and the consequences are left unaddressed.

Two astronomers think they found evidence in the Cosmic Microwave Background Radiation that the amount of dark matter in the universe is far smaller than currently thought.
