MOND vs. Dark Matter: Research suggests that the rotation curves of galaxies remain flat indefinitely

by

The main technique Mistele used in his research, gravitational lensing, is a phenomenon predicted by Einstein’s general theory of relativity. As part of the research, Mistele plotted the so-called Tully-Fisher relationship on a map to highlight the empirical relationship between a galaxy’s visible mass and its rotation rate. In a discovery that challenges conventional understanding … Read more

The clashing galaxies NGC 4568 (bottom) and NGC 4567 (top) as seen by the Gemini North telescope in Hawai‘i

Eventually, all galaxies, including our own Milky Way, will come to an end. But how do galaxies die? If you’re in the mood to destroy an entire galaxy, you have several options depending on the level of destructiveness you want.

Simulated Roman image full of synthetic galaxies

Researchers delve into a synthetic universe to help us better understand the real universe. Using supercomputers at the Department of Energy’s Argonne National Laboratory in Illinois, scientists have created nearly 4 million simulated images of the cosmos from NASA’s Nancy Grace Roman Space Telescope and the Vera C. Rubin Observatory, jointly funded by NSF (the … Read more
