A proposed census rule would exclude undocumented immigrants from being counted and omit questions on race and sexual orientation to prevent 'distortions'.
기초과학연구원(IBS) 연구팀이 암흑물질 후보인 액시온 탐색 연구에서 1.036㎓ 액시온 후보 신호를 검증했으나, 독립적인 실험과 재탐색을 통해 실제 액시온 신호가 아닌 것으로 결론 내렸다. 연구팀은 이를 통해 액시온 후보 영역을 더 정밀하게 규명했다.
A third galaxy, DF9, has been found to be missing dark matter, joining DF2 and DF4 along the NGC 1052 trail. Observations suggest DF9's mass is almost entirely from its stars, challenging the assumption that galaxies are dominated by dark matter. This discovery strengthens the theory that a single disruptive event created these unusual galaxies.
Astronomers using the James Webb Space Telescope have discovered supermassive black holes that formed within the first billion years of the universe, challenging existing theories. Researchers now propose that decaying dark matter particles with masses between 24-27 electronvolts may have released enough energy to prevent gas cloud fragmentation, causing direct collapse into massive black holes instead of star formation.
