Why hasn’t matter fallen apart over billions of years? The mystery might start with protons. Scientists continue to conduct experiments that have yet detected proton decay but discovering it would reveal new insights into the fundamental laws of nature.

A repost of the U.S. Department of Energy’s Office of Science. Now that the excavation of the LBNF-DUNE project is complete, science and engineering teams are developing the detectors and systems DUNE will use to study neutrinos. The launch of LBNF/DUNE will bring a new era in understanding neutrinos and knowing more about our universe as a whole.

In a trillion or so years’ time, the Universe will have exhausted all of its star-forming material. The last star will be born and from thereon the Universe will face a slow death as gradually each and every star burns out. Fermilab’s Dan Hooper discusses how life will struggle to survive into the deep future but dark energy is intent on stealing the stars 100–150 billion years into the future.

NPR’s Short Wave host spoke with Fermilab Cosmologist Brian Nord about what dark energy could be and what it implies about the end of our universe.

Here’s what recent DESI measurements suggest — and why it’s too early to update conventional predictions about the Universe’s distant future.

Researchers have used the Dark Energy Spectroscopic Instrument to make the largest 3D map of our universe and world-leading measurements of dark energy, the mysterious cause of its accelerating expansion.

Physicists use particle accelerators to replicate the early Universe’s conditions, revealing insights from the Big Bang to the formation of atoms. Data generated in particle physics experiments and theoretical physics can offer a glimpse into the earliest moments of the cosmos.

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

Kmele Foster, host of Dispatches from The Well, visited Fermilab last spring to speak with scientists about how exploring the mysteries at the heart of particle physics can help us better understand some of the most profound mysteries of our universe. This Big Think production features Bonnie Fleming, Don Lincoln, Doga Kurkcuoglu and Rachel Pfaff.

Don Lincoln explores Einstein’s theory of general relativity as introducing the concept of space having a shape. So, what is the shape of space?
