Einstein’s equation E = mc2and the theory of the Big Bang are both generally accepted physics theories, and yet, between them, they make an unphysical prediction. They predict that matter and antimatter should be observed in equal quantities. Yet the universe is made only of matter. Why is that? In this 11-minute episode of Subatomic Stories, Fermilab scientist Don Lincoln explains what is going on.

Mysteries abound in the universe, including the universe’s ultimate fate. In this episode of Subatomic Stories, Fermilab scientist Don Lincoln talks about the observation of a new form of energy called dark energy, which will determine the future of the cosmos.

We know very little about what happened in the first seconds after the Big Bang. In this public lecture, author and Fermilab physicist Dan Hooper examines how physicists are using the Large Hadron Collider and other experiments to re-create the conditions of the Big Bang and to address mysteries such as how our universe came to contain so much matter and so little antimatter.

There are mysteries in the cosmos that general relativity can’t explain, such as how galaxies rotate and how clusters of galaxies move. Scientists have ideas as to possible explanations. In this 13-minute episode of Subatomic Stories, Fermilab scientist Don Lincoln lists some of the most pressing mysteries.

Black holes live up to their name. They emit no light and they’re usually very far away. This makes it hard to take pictures of them, and indeed, some people claimed that they might not exist. But that’s no longer true. In episode 19 of Subatomic Stories, Fermilab scientist Don Lincoln tells us how we are quite sure that black holes are real.

Black holes seem to be timeless, lurking in the cosmos, forever eating and growing. However, astronomers believe that there is a way for black holes to shrink in size and eventually evaporate away. In episode 18 of Subatomic Stories, Fermilab scientist Don Lincoln talks about Hawking radiation, the ultimate fate of black holes.

Scientists on the Dark Energy Survey have used observations of the smallest known galaxies to better understand dark matter, the mysterious substance that makes up 85% of the matter in the universe. The smallest galaxies can contain hundreds to thousands of times more dark matter than normal visible matter, making them ideal laboratories for studying this mysterious substance. By performing a rigorous census of small galaxies surrounding our Milky Way, scientists on the Dark Energy Survey have been able to constrain the fundamental particle physics that governs dark matter.

This 4-minute animation takes you on a flight that starts on Earth and travels one billion light years into space and back. It features data recorded by the Sloan Digital Sky Survey collaboration. Using the data recorded over the last 20 years, the SDSS collaboration has created the most detailed three-dimensional maps of the universe ever made, with deep multicolor images of one third of the sky, and spectra for more than three million astronomical objects.
