论文摘要
将黑洞的热力学从地平线扩展到肌肉发达的高度，并建立了爱因斯坦方程与热力学之间的一般关系。从通过Bekenstein-Hawking熵概括的微不足道的熵开始，物质的熵质量与未温度自然出现。关键的思想是，质量形成的原因归结为微不足道的熵，而质量密度只是质量的外部表现。带有宇宙常数的完整爱因斯坦方程来自熵质量和适当质量等效的要求。这种观点表明，引起重力质量的琐碎熵可能是时空几何起源的最佳选择。
Expanding the black hole thermodynamics from the horizon to achronal Cauchy hypersurface, the general relation between the Einstein equation and thermodynamics is established. Starting from trivial entropy that is generalized by Bekenstein-Hawking entropy, the entropic mass of matter emerges naturally together with Unruh temperature. The key idea is that the cause of mass formation comes down to trivial entropy, and mass density is just the external manifestation of mass. The full Einstein equation with the cosmological constant is derived from the requirement that entropic mass and proper mass are equivalent. This perspective suggests that trivial entropy that causes mass in gravitation may be the best choice for the origin of space-time geometry.
