"This discovery poses a challenge to the Lambda Cold Dark Matter model, which may struggle to account for the formation of such small, aligned groups of galaxies in isolated environments." ...

It has also uncovered many shortcomings of our current models of the universe. While we are refining our models to account for the shortcomings, we are, at the same time, excited about the ...

One of the challenges in doing so is that the model does help explain many other elements of the universe with high certainty. “The Hubble constant is one of the basic constants that you can put ...

In the zoom-in section, the underlying structure of matter in our Universe is easy to see. Their results confirm the validity of Einstein's theory of gravity, general relativity, on cosmological ...
