cosmology

From MIT news, April 12, 2023: MIT News talks with Brian Nord about continuing his research at MIT as part of the Martin Luther King Jr. Visiting Scholars and Professors Program.
While using AI machines to explore the cosmos, he is also dedicated to creating equity in academic and research environments.

From Physics, Jan. 31, 2023: Fermilab scientists are part of a group of researchers using cross-correlation measurements combining data from the Dark Energy Survey and the South Pole Telescope to determine cosmological parameters with greater precision. The analysis involved more than 150 researchers with results published as a set of three articles in Physical Review D.

Perhaps the grandest questions of all are those of how the universe came to be, how it has evolved, and how it will end. While modern science does not have all the answers, the scientific community has discovered many facts that allow us to understand much of this story. In this public lecture, presented on Dec. 9, 2022, Don Lincoln explains what we know — and what we don’t know — about these ageless questions.

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.

The cosmic microwave background has been a treasure trove of information about the universe, as well as a source of questions that have not yet been resolved. In this video, Don Lincoln describes two unsolved mysteries of the CMB. The first makes you ask if the solar system has a special place in the universe, and the second is a giant cold spot that could be the signature of a giant void or, much more unlikely, of colliding universes.

The cosmic microwave background is the fossil remnant of the fireball of the Big Bang. Aside from demonstrating that the Big Bang happened, it can tell us how big the universe is and how much dark matter and energy the universe contains. In this video, Fermilab’s Don Lincoln guides you through this interesting topic.
