The discovery of the cosmic acceleration problem truly inspired me as a teenage physics nerd. Recent, related revelations about dark energy will hopefully capture the interest of today’s young science geeks,

A study by Dartmouth researchers proposes a new theory about the origin of dark matter, the mysterious and invisible substance thought to give the universe its shape and structure. They say the hypothetical force shaping the universe sprang from particles that rapidly condensed,

Astronomers have made an intriguing discovery that could upend everything we know about the structure of the universe and its expansion.

Shocking’ results from a major astronomical study have raised doubts about the standard model of cosmology, forcing scientists to consider new ways of understanding dark energy and gravity

What is the other 95 percent? Dark Universe examines the invisible dark matter underlying galaxies that, together with dark energy, accounts for that other 95 percent of the universe’s total energy and mass. Narrated by astrophysicist Neil deGrasse Tyson.

If dark energy ebbs with time, which now seems plausible, the universe could one day stop expanding and then eventually collapse on itself in what is called the Big Crunch. It might not seem like the cheeriest fate, but it offers some closure, said cosmologist and study collaborator Mustapha Ishak-Boushaki of the University of Texas at Dallas.

"This shocking result means that we now need to revisit the very foundations of everything we know about cosmology," said the reseachers.

Adam Riess, winner of the Nobel Prize in Physics, discussed how his research rewrote the fundamental story of the universe.

Dark matter, though invisible, weighs heavily on how we understand the universe. Its gravity sculpts galaxies, holds clusters together, and shapes cosmic evolution—yet we still don’t know what it is.
