【摘要】 利用经广义测不准关系改进的薄层brick wall方法计算了deSitter时空背景下宇宙的熵.结果表明,用这种方法得到的宇宙熵与视界面积成正比,与人们预期的结果相符.从中揭示了宇宙的熵与视界面积之间的内在联系,也进一步表明了宇宙的熵是视界面上量子态的熵,是一种量子效应.更多还原

【Abstract】 The entropy of universe is calculated by the improved brick-wall method due to the generalized uncertainty relation.The entropy of this system includes the contribution of the universe horizon.It is found that there is an internal relation between the event horizon and the entropy.更多还原
