How accurate is general relativity?

Recently, these telescopes have measured the deflection of radio waves by the Sun to extremely high precision, confirming the amount of deflection predicted by general relativity aspect to the 0.03\% level.

What was Einstein’s theory of general relativity in simple terms?

What is general relativity? Essentially, it’s a theory of gravity. The basic idea is that instead of being an invisible force that attracts objects to one another, gravity is a curving or warping of space. The more massive an object, the more it warps the space around it.

What conclusion did Einstein make about gravitation?

After years of struggle, Einstein succeeded in showing that matter and spacetime mutually interact to mimic Newton’s naïve idea that masses attract each other. Gravity, said Einstein, actually moved matter along the curving pathways embodied in spacetime — paths imprinted by mass and energy themselves.

When was the general theory of relativity proven true?

Subsequently, Arthur Stanley Eddington’s 1919 expedition confirmed Einstein’s prediction of the deflection of light by the Sun during the total solar eclipse of 29 May 1919, which helped to cement the status of general relativity as a viable theory.

What is the elusive theory of Everything about?

In a new book, The Grand Design, Hawking and Caltech physicist Leonard Mlodinow argue that the quest to discover a final theory may in fact never lead to a unique set of equations. Every scientific theory, they write, comes with its own model of reality, and it may not make sense to talk of what reality actually is.

What proved that the general theory of relativity was accurate?

Their objective was to see whether the stars around the blackened disc of the Sun appeared displaced—an indication that massive objects would indeed bend the course of light, as Einstein had predicted in his general theory of relativity. …
