物理学中一项巨大的未解难堪
牛顿提出引力理论已有340年，但科学家至今仍未完全破解引力的奥秘。这一问题被称为物理学中最令人尴尬的未解难题之一。尽管相对论和量子力学取得了巨大成功，引力却始终拒绝与其他基本力统一，让物理学家们苦苦思索。文章探讨了引力的本质、它与量子理论的矛盾，以及科学家们为解开这一谜团所做的种种努力。

A new paper by Thomas Bloom, Will Sawin, Carl Schildkraut and Dmitrii Zhelezov disproves a well-known conjecture in additive combinatorics. The result shows there exist arbitrarily large finite sets A of real numbers where max(|A+A|,|AA|) ≤ |A|^{2-c}. The solution was achieved by humans using methods related to an earlier AI solution to the unit distance conjecture.
