Dec. 28 (UPI) Scientists have found most of the universe s missing matter and explained how the early universe became reionized. Yet several of the cosmos mysteries remained unsolved like why the universe continues to expand faster and faster over time.
The force explaining the universe s accelerating expansion has long been considered one of the cosmos most important missing components the missing link in the currently not-quite-right theory of the universe.
UChicago scientist lays out how LIGO gravitational waves could be scrambled, yielding information
There’s something a little off about our theory of the universe. Almost everything fits, but there’s a fly in the cosmic ointment, a particle of sand in the infinite sandwich. Some scientists think the culprit might be gravity and that subtle ripples in the fabric of space-time could help us find the missing piece.
A new paper co-authored by a University of Chicago scientist lays out how this might work. Published Dec. 21 in
Physical Review D, the method depends on finding such ripples that have been bent by traveling through supermassive black holes or large galaxies on their way to Earth.
