Binary black holes release energy in the form of gravitational waves – ripples in space-time that specialized observatories can detect. According to Einstein’s general relativity theory, these ripples ...
Binary black holes release energy in the form of gravitational ... kind of like a wave. Pulsar timing arrays use pulsars, which are the dense, bright cores of collapsed stars.
Pulsar timing arrays use pulsars ... And even the most powerful telescopes can’t image these binary black holes directly. So, astronomers have to use clever indirect methods to figure out ...
