What is the evidence for general relativity?
Gravitational-wave astronomy can test general relativity by verifying that the observed waves are of the form predicted (for example, that they only have two transverse polarizations), and by checking that black holes are the objects described by solutions of the Einstein field equations.
How has relativity been proven?
Tests of general relativity General relativity has also been confirmed many times, the classic experiments being the perihelion precession of Mercury’s orbit, the deflection of light by the Sun, and the gravitational redshift of light. Other tests confirmed the equivalence principle and frame dragging.
What is the proof of time dilation?
There are several direct proofs of time dilation. Extremely accurate clocks have been flown on jet aircraft. When compared to identical clocks at rest, the difference found in their respective readings has confirmed Einstein’s prediction.
How time dilation is experimentally verified?
Time dilation as predicted by special relativity is often verified by means of particle lifetime experiments. According to special relativity, the rate of a clock C traveling between two synchronized laboratory clocks A and B, as seen by a laboratory observer, is slowed relative to the laboratory clock rates.
How was Einstein’s theory of relativity supported by experimental evidence?
This experimental support for his general theory of relativity garnered him instant worldwide acclaim. Further evidence came from the planet Mercury. In the 19th century, it was found that Mercury does not return to exactly the same spot every time it completes its elliptical orbit.
What is the Best Experimental Test of special relativity?
If you’re asking for experimental tests of special relativity, arguably the first one is the Michelson-Morley experiment. Subsequent to that, there have been an enormous number of tests that verify it to incredible precision – a comprehensive account with references can be found here:
What are the manifestations of general relativity?
One manifestation of general relativity is gravitational waves, depicted here as created by two colliding black holes. the fabric of space-time. (Image credit: R. Hurt/Caltech-JPL)
What is the most striking prediction of general relativity?
The most striking prediction of general relativity is that of gravitational waves. Electromagnetic waves are caused by accelerated electrical charges and are detected when they put other charges into motion. Similarly, gravitational waves would be caused by masses in motion and are detected when they initiate motion in other masses.
