It’s one of the leading puzzles in cosmology. Why two different approaches used to calculate the rate at which the cosmos is expanding don’t produce the same result. Branded as the Hubble tension, the conundrum suggests that there could be
Read Full ArticleMizzou researchers are peering into the past and revealing new clues about the early cosmos. Since light takes a very long time to travel through space, they have the opportunity to see how galaxies looked billions of years ago.In a

Read Full ArticleFor as long as humans have envisioned the Universe, we’ve gaped at the vastness of it all. Was our Cosmos infinite? Was it eternal? Or did it come into being a finite amount of time ago? Over the 20th and
Read Full ArticleAbout 2,500 years ago humanity began to recognize that our planet earth is round—though a few “flat Earth” supporters still refute this today. The shape of our cosmos is not clear, however. Previous studies have proposed that the universe probably
