General Relativity

Researchers have pinpointed why planets orbiting two stars, like Tatooine in Star Wars, are rarer than expected. Einstein's general theory of relativity causes orbital instabilities that eject or destroy most such planets around tight binary stars. Only 14 confirmed circumbinary exoplanets exist among over 6,000 discovered.

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.
