General Relativity
Scientists are proposing a method to test Einstein's general theory of relativity by analyzing high-resolution images of black hole shadows. Their new simulations suggest that future telescope advancements could reveal if alternative gravity theories hold true. The work, led by researchers from Goethe University Frankfurt and the Tsung-Dao Lee Institute, appears in Nature Astronomy.
