Don Lincoln explores if spaghettification is real and will an object get stretched as it falls into a black hole?

Don Lincoln explores the mysteries of black holes and if we will ever really know what lies in the center of these enormous cosmic regions in space.

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.

Astronomers have unveiled the first image of the supermassive black hole at the center of our own Milky Way galaxy. This result provides overwhelming evidence that the object is indeed a black hole and yields valuable clues about the workings of such giants, which are thought to reside at the center of most galaxies.

A new computer program called MARLEY simulates supernova neutrino interactions in argon-based particle detectors.

Researchers make progress on a vexing problem about how black holes evolve.

From Forbes, Jan. 19, 2021: Fermilab scientist Don Lincoln contextualizes the discovery of the most distant (and therefore oldest) supermassive black hole found thus far, which is 10 trillion times brighter than our sun.

Until recently, scientists had never detected black holes in the “mass gap.” Now, particle physicists are exploring ideas beyond the Standard Model that could explain them.

The NOvA experiment, best known for its measurements of neutrino oscillations using particle beams from Fermilab accelerators, has been turning its attention to measurements of cosmic phenomena. In a series of results, NOvA reports on neutrinos from supernovae, gravitational-wave events from black hole mergers, muons from cosmic rays, and its search for the elusive monopole.

In recent years, scientists have found ways to study black holes, listening to the gravitational waves they unleash when they collide and even creating an image of one by combining information from radio telescopes around the world. But our knowledge of black holes remains limited. So scientists are figuring out how to make do with substitutes — analogs to black holes that may hold answers to mysteries about gravity and quantum mechanics.
