How fast is the universe expanding? Scientists may soon find an answer as a new study reveals the rate of the universe's expansion could potentially be measured by gravitational waves from black holes and neutron stars.
Black holes remain to be one the most perplexing objects in the night sky as they constantly appear to be contradicting the very laws of physics. However, recent data suggests there is really more to black holes than meets the eye, and it can shake the foundation of a lot of theories.
Scientists have said that LIGO's first detection of gravitational waves from two merging black holes is 12 billion years in the making, and there will be thousands of collisions to occur in the future.
Scientists from LIGO has detected a second batch of gravitational waves from two colliding black holes, disproving a previous assumption that collisions produce bursts of radiations.
A team of researchers, scientists, and engineers from Laser Interferometer Gravitational-Wave Observatory (LIGO) announced last February the discovery of tiny ripples in space and time caused by two merging black holes, as theorized by Einstein, using a pair of giant laser detectors.
