Gravitational waves / Elementary Tour: Conclusion
Gravitational waves promise a glimpse into regions of our cosmos that are inaccessible to regular astronomical observation. In the past, whenever astronomers have opened a new window to the universe (for example, at the beginning of radio astronomy or X-ray astronomy), this has brought about new, and often unexpected, results for astrophysics. With gravitational waves, researchers hope for a similar leap forward.
With the first direct detection of gravitational waves in 2015, the gateway to gravitational wave astronomy was opened. Now an exciting time begins for astrophysics in which the new window to the cosmos can be explored in practice.
Elementary Einstein continues with a look at some compact objects that make promising sources for gravitational waves:
