What are the predictions of general theory of relativity?

General relativity predicts that the path of light will follow the curvature of spacetime as it passes near a star. This effect was initially confirmed by observing the light of stars or distant quasars being deflected as it passes the Sun.

What are the main conclusions of general relativity?

The equations of general relativity predict a number of phenomena, many of which have been confirmed: bending of light around massive objects (gravitational lensing) a slow evolution in the orbit of the planet Mercury (perihelion precession) frame dragging of space-time around rotating bodies.

What is robust prediction of the general theory of relativity?

“for the discovery that black hole formation is a robust prediction of the general theory of relativity”

What are the assumptions of general relativity?

Assumptions that Einstein used to develop his General Theory of Relativity: The laws of nature are the same in different frames of reference (where acceleration is taken into consideration). Gravitational mass is equivalent to inertial mass.

What are three of the main conclusions of general relativity?

Conclusion

• There is no such thing as an absolute (completely stationary) frame of reference.
• The laws of physics apply equally to all frames of reference.
• The speed of light is constant in all frames of reference.
• There is no simultaneity of events between separate frames of reference.
• You are never too old to learn.

Who discovered black holes Stephen Hawking?

Hawking is best known for his discovery that black holes emit radiation which can be detected by special instrumentation. His discovery has made the detailed study of black holes possible. Stephen Hawking was born in Oxford, England on January 8, 1942. At the age of 17, he enrolled at University College, Oxford.

How black holes are discovered?

Most known black holes have been found by searching for the x-rays emitted when the invisible object pulls material off an orbiting companion star. As that material heats up in a dense ring around the black hole, known as an accretion disk, it emits radiation that can be detected with x-ray telescopes.

How does general relativity predict black holes?

Black holes are regions of spacetime where gravity’s pull is so strong that nothing, not even light, can escape from being dragged in and “eaten.” Einstein’s theory of general relativity predicted the existence of black holes and that, no matter what such an object “eats,” black holes are characterized only by their …
