From Live Science, April 29, 2020: One of the deepest mysteries in physics could be explained by a long-since vanished form of dark matter. Fermilab scientist Dan Hooper is one of the authors of the new result. If an ancient form of dark matter decayed out of existence, that loss would have decreased the mass of the universe, which would have led to less gravity holding the universe together, which would have affected the speed at which the universe expands — helping explain the disagreement between measurements of the universe’s expansion.

With this six-minute video, Fermilab scientist Don Lincoln launches a special series called Subatomic Stories. You will learn a little bit about both the exciting subatomic world and the entire cosmos — and see how the two are inextricably linked. Each episode will focus on a specific topic, but the series will tell a much broader story.

Understanding how the universe began has been a goal for scientists, philosophers, and theologians for millennia. In this 14-minute video, Fermilab scientist Don Lincoln describes the scientific view on this topic. He covers what we know, what we think and what we may forever never know.

From Five Books, March 30, 2020: Fermilab scientist Dan Hooper gives his recommendations for books on the Big Bang and talks about whether our entire understanding of the universe is about to be turned upside down.

From Kane County Chronicle, Feb. 24, 2020: Join Fermilab scientist emeritus Paul Mantsch at the St. Charles Public Library on Tuesday, Feb. 25, at 7 p.m. as he explains how the realms of the atom and the cosmos are intimately connected to each other – and to us. This special presentation will feature the story of discovery at Fermilab: past, present, future.

From The Guardian’s Science Weekly podcast, Feb. 14, 2020: What happened at the dawn of the universe, just trillionths of a second after the start of the big bang, remains a mystery. Revisiting these moments in his new book, “At the Edge of Time,” Fermilab scientist Dan Hooper explores many of the unknowns in cosmology. Hooper guides Ian Sample through the birth of our universe to its enigmatic constituents of dark matter and dark energy in this 22-minute podcast episode.

Reina Reyes made headlines for her research at Princeton testing Einstein’s theory of general relativity; now she’s home in the Philippines, using her physics background to make her mark in different ways.
