The next sea-level monitoring satellite, Copernicus Sentinel-6B, has begun its journey from Europe to the Vandenberg Space Force Base in California, where it is scheduled to launch in November. Carefully packed into a climate-controlled container, the satellite is currently crossing the Atlantic Ocean aboard the cargo ship Industrial Dolphin.
Astrophysicists don't know if direct-collapse black holes are real. They were hypothesized to explain how the Universe could contain supermassive black holes (SMBH) so early. They don't require a stellar progenitor, nor do they require hierarchical merging. Instead, they collapse due to instability in a gas cloud, much like stars do.
