| Abstract Title: |
W05: Modern Eddington Experiment |
| Abstract: |
History was made and Einstein became famous in 1919 when Eddington and Dyson measured the Einstein Coefficient. Between 1919 and 1957 several additional experiments were performed with varying success, but the images obtained were entirely beyond twice the radius of the sun, and the data was very limited (7 stars for 1919 and only a total of about 100). At this distance the gravitational deflection is very small and lies out in the tail of the hyperbolic curve (1/r) for photon deflections. This makes a curve fit verification questionable. After no experiments being performed until 2017, two experiments were successful one by Don Bruns and one by Dittrich/Berry (involving four undergraduate students who became the first to ever measure the curvature of space). The modern CCD cameras used captured hundreds of images. For the April 2024 eclipse, Professor Dittrich has organized more than 10 teams using new CMOS cameras that will be able to capture hundreds of thousands of images, many between R = 1-2 solar radii. This will enable the creation of the first ever adequate curve fit verification of Einstein's hyperbolic deflection relationship. This Modern Eddington Experiment will involve many colleges and undergraduates as well as amateur astronomers from around the world. This workshop will discuss the MEE2024 project. |
