The international collaboration, including Fermilab, the National Center for Supercomputing Applications, NOIRLab and others, releases a massive, public collection of astronomical data and calibrated images from six years of surveys. This data release is one of the largest astronomical catalogs issued to date.
From Forbes, Jan. 5, 2021: Two measurements of the speed at which the universe is currently expanding disagree. It could be the first signs that cosmologists will have to make significant changes to their understanding of the cosmos. Fermilab scientist Don Lincoln explains.
From CNN, Dec. 18, 2020: Fermilab scientist Don Lincoln summarizes the results of a group of researchers who, through simulation, reconstruct the family tree of the Milky Way, including the merging of the previously unknown dwarf galaxy Kraken.
Many provocative ideas have been proposed about the ultimate nature of our universe. In this 14-minute episode of Subatomic Stories, Fermilab scientist Don Lincoln discusses the possibility that our universe might actually be a simulation.
There are many ideas rattling around the theoretical physics community that sound outlandish, and one stands out — the idea that our universe is actually a hologram. In this 12-minute episode of Subatomic Stories, Fermilab scientist Don Lincoln sketches the theory of the holographic universe.
One of the great unanswered questions of science is why the laws of the universe seem so carefully tuned to allow for the existence of stars, galaxies, even humans. Scientists, philosophers and theologians have long mulled over this mystery. In this 15-minute episode of Subatomic Stories, Fermilab scientist Don Lincoln talks about the multiverse, which is a highly speculative possible answer to the question.
The universe seems eternal, but it has a future and an eventual death. In this video of Subatomic Stories, Fermilab scientist Don Lincoln talks about how the universe will expand and evolve.
The moment our universe came into existence fits one part of the definition of a miracle very well, as does the appearance of the imbalance between matter and antimatter.
Scientists have long called the expanding universe “the Big Bang,” but the term is confusing. Many people think the Big Bang is the name of the moment of the creation of the universe, but it’s really just the expanding phase. In this episode of Subatomic Stories, Fermilab scientist Don Lincoln explains some of the speculative ideas that have been proposed about the actual and literal moment of creation.
The first moments of the universe are still not well understood by modern science. While the theory of the Big Bang covers the big picture, it doesn’t address some detailed questions. In this episode of Subatomic Stories, Fermilab scientist Don Lincoln describes the idea of inflation, which is an addition to the Big Bang. Together, the two theories appear to be another step forward in our understanding of the origins of the cosmos.
