✨Theory of relativity

  Language Theory of relativity The theory of relativity usually encompasses two interrelated theories by Albert Einstein: special relativity and general relativity.  Special relativity applies to all physical phenomena in the absence of gravity. General relativity explains the law of gravitation and its relation to other forces of nature.  It applies to the cosmological and astrophysical realm, including astronomy. Two-dimensional projection of a three-dimensional analogy of spacetime curvature described in general relativity The theory transformed theoretical physics and astronomy during the 20th century, superseding a 200-year-old theory of mechanics created primarily by Isaac Newton.    It introduced concepts including spacetime as a unified entity of space and time, relativity of simultaneity, kinematic and gravitational time dilation, and length contraction. In the field of physics, relativity improved the science of elementary particles and their fun...

💥The Sun Helped Prove Einstein Right for his General Relativity theory.

As any good scientist knows, an unproven theory isn’t science, it’s philosophy. Einstein needed his equations to make accurate predictions about the behavior of objects in space.  One of his conjectures held that light traveling near a large gravitational field should curve. To test it, Einstein needed the help of a solar eclipse, which would facilitate the view of starlight passing through the sun’s gravitational field. On May 29, 1919, in a test conceived by astronomer Sir Frank Watson Dyson, and with the help of Sir Arthur Eddington, astronomers were able to take pictures to compare with their "true" location and measure the bend of light of 1.75 arcseconds—the very number Einstein’s theories predicated. “LIGHTS ALL ASKEW IN THE HEAVENS” read the November New York Times headline. From that moment on, Einstein was a superstar. @SciSujan
