The Universe Is Expanding Too Fast and Scientists Can’t Explain Why
The most precise measurement yet shows the Universe is expanding faster than expected, deepening the Hubble tension. The result hints that something may be missing from our current understanding of the cosmos.
An international team of astronomers has produced one of the most accurate measurements so far of how quickly the nearby Universe is expanding. Rather than settling a long-standing debate, the new result intensifies one of the biggest unresolved problems in cosmology. The collaboration includes John Blakeslee of NSF NOIRLab, which is funded by the U.S. National Science Foundation, and draws on data from telescopes across two NSF NOIRLab Programs.
Two competing ways to measure cosmic expansion.
Toxic Combinations: When Cross-App Permissions Stack into Risk
Moltbook’s agents sat at that bridge, carrying credentials for their host platform and for the outside services their users had wired them into, in a place that neither platform owner had line of sight into. Most SaaS access reviews still examine one application at a time, which is the blind spot attackers are learning to target.
How Toxic Combinations Form
Toxic combinations are rarely the product of a single bad decision. They appear when an AI agent, an integration, or an MCP server bridges two or more applications through OAuth grants, API scopes, or tool-use chains, and each side of the bridge looks fine on its own because the bridge itself is what no one reviewed.
