Gravitational wave 'memories' could help us find elusive cosmic strings
Many theories of the early universe predict that the cosmos should be flooded with cracks in space-time, called cosmic strings, but no cosmic strings have been detected yet.
'Exotic compact objects' could soon break physics, new study suggests
Gravitational wave detectors could soon uncover hints of new physics from exotic compact objects.
Black holes, string theory and more: Q&A with physicist Brian Greene
Space.com caught up with Greene to discuss the importance of science education, why black holes are so interesting and whether a "theory of everything" breakthrough could be on the horizon.
'Dark sirens' could solve one of the greatest mysteries in cosmology
A team has offered a way for gravitational wave events called dark sirens to resolve a crisis in cosmology
Dark matter could be made of black holes from the beginning of time
Evidence of collisions between black holes and neutron stars suggests dark matter might consist of concentrations of primordial black holes.
A tiny crystal device could boost gravitational wave detectors to reveal the birth cries of black holes
In 2017, astronomers witnessed the birth of a black hole for the first time.
A mission to Uranus and Neptune could act as massive gravitational-wave detector
What if one mission could study the gravitational ripples triggered by some of the most violent events in the universe — on the way to observing the least-known planets of our solar system?
Superpowerful 'oscillon' particles could have dominated the infant universe, then vanished
A weird, super-powerful particle that's not truly a particle could have dominated the universe when it was just a second old, releasing a flood of ripples that permeated all of space-time.
