From Big Think, Jan. 25, 2023: How old is the universe? Don Lincoln discusses the Methuselah Star measure versus the Big Bang theory.

From Big Think, Jan. 6, 2023: While astronomers debate the existence of dark matter, Don Lincoln breaks down a new paper published in Nature Astronomy that claims to debunk a key observation that strengthens the case that the Universe is full of unseen matter.

From the University of Chicago News, Dec. 8, 2022: A new study in Nature Astronomy proposes sending an atomic clock onboard a spacecraft to fly close to the sun in order to detect the mysterious substance known as dark matter. By finding dark matter and understanding its properties, we might then understand the evolution of our universe.

From the Big Think, Nov. 30, 2022: Don Lincoln discusses that while the Universe we see is made solely of matter, there is no explanation for this fundamental asymmetry.
Understanding why the Universe was created with more matter than antimatter is key to understanding why anything exists.

From the Big Think, November 14, 2022: Gaia BH1 is the closest black hole to Earth that scientists have ever discovered at just 1,600 light years away. Fermilab’s Don Lincoln examines that by looking at the behavior of a star near the black hole, how astronomers might be able to determine the black hole was there, despite never seeing it directly.

From CNET, November 13, 2022: View new photos of radiant galaxies released by NASA using the Dark Energy Camera, developed and tested by Fermilab, and the Hubble Space Telescope. These new images show galaxies scattered across the universe some 200 million light-years away.

From Big Think, Nov. 2, 2022: Don Lincoln explores Hubble tension, two very precise yet conflicting estimates of the rate at which the Universe is expanding. While the of Universe expansion is consistent, the two ways in which this is measured begs the question if something is missing in cosmology theory.

From Big Think, September 28, 2022: 13.8 billion years ago when the Big Bang exploded expanding and resulting in the universe we see today. Don Lincoln examines the expansion of the universe and how it is still evolving today.

From CNN, September 26, 2022: Don Lincoln discusses how NASA and researchers slammed a 570 kilogram spacecraft called Double Asteroid Redirection Test (DART) into the Dimorphos asteroid to test if the impact will change the asteroid’s trajectory and help scientists understand if potentially dangerous space rocks can be diverted before they endanger the Earth.

From the Big Think, September 20, 2022: Don Lincoln ponders the size of the Universe. That is the hypothetical Universe versus the actual Universe. Read more about what we don’t know and what we do know about the Universe that began almost 14 billion years ago.
