Is this accepted throughout the science community now? Is there any doubt that LIGO actually detected gravity in the form of waves?
.. we report correlations in the detector noise which, at the time of the event, happen to be maximized for the same time lag as that found for the event itself ... A clear distinction between signal and noise therefore remains to be established in order to determine the contribution of gravitational waves to the detected signals.
Gravitational waves are ripples in the fabric of space-time caused by the acceleration of massive objects, such as black holes or neutron stars. They were first predicted by Albert Einstein in his theory of general relativity.
Gravitational waves were first directly detected in 2015 by the Laser Interferometer Gravitational-Wave Observatory (LIGO). This involved using laser interferometry to measure tiny distortions in space-time caused by passing gravitational waves.
The confirmation of gravitational waves provides further evidence for Einstein's theory of general relativity and opens up a new way of observing and understanding the universe. It also allows us to study and learn more about objects in the universe that emit gravitational waves, such as black holes and neutron stars.
Yes, there are other methods being developed to detect gravitational waves, such as using pulsar timing arrays or space-based interferometers. These methods may allow us to detect gravitational waves from different sources and at different frequencies.
At this time, gravitational waves do not have any practical applications. However, as our understanding of them grows, they may potentially be used for things such as precision measurements or studying the early universe.
