A new study shows dark matter falls into cosmic gravity wells much like ordinary matter, narrowing one of astronomy’s biggest mysteries. Researchers say any unknown force acting on dark matter must be very weak, though future missions could detect smaller effects. The findings bring scientists closer to understanding how the universe’s unseen mass behaves.

Astronomers from Yonsei University and DESI data analyses indicate dark energy, long believed constant, may be weakening. Corrected supernova results hint that cosmic acceleration is slowing—a possible “cosmic slowdown.” If true, this could help resolve the Hubble tension and redefine how the universe’s expansion and ultimate fate are understood.

Researchers have created a new fiber that surpasses Kevlar in bullet-stopping power while being much thinner. Made by aligning advanced aramid chains with carbon nanotubes, the material absorbs over twice as much energy as previous record-holding fibers. The breakthrough could lead to lighter, stronger armor for military, law enforcement and personal safety uses.
