21st august is going to be an experimental day for sky watchers as well as for researchers. It’s going to be total solar eclipse on 21st august 2017. The same experiment was performed before also in 20th century by an astrophysicist. His name was Arthur Eddington, who wants to prove that gravity could bend light also. It’s a principle of Albert Einstein’s theory of general theory. Don Bruns, an amateur astronomer who again want to perform the experiment. In an interview given to live science he told that two year before only he planned about it. He knew that others may have also tried it before. But since 1973 no one had thought about it. In Einstein’s theory of general relativity that was published in 1915, he state that light will bend around massive objects because space itself becomes curved around such objects. After several years of publication, researchers got opportunity to test the theory on 29th may 1919, when total solar eclipse formed.
Under the experiment, deflection of light was to be measured that was emitting from stars near the sun in the solar system. Eddington and his team were observing simultaneously from Brazil and Africa. The observed that star position those were close to solar limb deviate from small amount from their listed position. Success of the experiment became the issue of debate for many other scientists. That’s why bruns wants to perform it again. Bruns stated that this time modern instruments and accurate measurements will help to repeat Eddingtons experiment without any error. Bruns plan is to observe clear skies from high altitude site in Wyoming.
Brun is not alone in the lab of experiments. Richard berry is also experimenting from Alpaca Meadous Observatory (own observatory). He was also an editor in chief of astronomy magazine. In reply to a query he told live science through email that he is working on the project along with four students and a college. It’s a Toby Dittrich of Portland Community College. He also showcased his experiment plans that on Oregon one of the physics students will be there and he with two students will capture pictures of the experiment.
Professor of astronomy at Louisiana state university, Bradley Schaefer have given detailed information about the equipment that sky watchers are going to use for modern Eddington experiment. It’s a warning for all those people who don’t know that serious eye damage or blindness could be occurred if anybody looks directly at the sun (covered partially by moon).
