Einstein’s theory of relativity passes major test

The video discusses pulsars, which are dense neutron stars emitting radiation from their magnetic poles. Researchers observed a double pulsar system for 16 years to study changes in timing of flashes visible from Earth. They aimed to compare these observations with Einstein's theory of general relativity, which predicts that such systems emit gravitational waves that drain orbital energy. The study found that the energy loss measured matched the predictions of general relativity.

What are pulsars and how do they emit radiation?

What does Einstein's general relativity predict about the double-pulsar system?

What are the implications of the gravitational ripples sent away by the double-pulsar system?

How do researchers measure the energy taken away by gravitational waves?
