Search results are ranked mostly by popularity and relevance signals, not by actual accuracy, letting false but engaging content rise to the top. A better system needs to weigh truthfulness, not just engagement.

Even experienced teams regularly introduce bugs into complex software, some of which cause expensive failures. Languages or tools that can mathematically guarantee certain classes of bugs can't exist would be a major step forward.

Millions of applications depend on open-source code maintained by volunteers, and a single hidden change can spread unnoticed to countless systems. A trustworthy verification system remains a major unsolved need.

These particles carry more energy than anything we can produce on Earth, and we still don't know exactly what cosmic event launches them our way. Identifying the source could reveal entirely new astrophysical processes.

Cosmic radiation gradually damages electronics, and there's no way to send a repair technician to fix something millions of miles away. More radiation-hardy systems are essential for missions lasting a decade or more.

This period, known as cosmic inflation, is widely accepted as a concept but the exact physical mechanism driving it remains unproven. Confirming it would close a major gap in our understanding of the universe's first moments.

The leading theory involves a massive collision with early Earth, but several details still don't perfectly match the evidence we've collected from lunar samples. A fuller explanation would clarify Earth's own early history too.
