论文摘要
在对弹跳宇宙学的正统解释上，在``弹跳''之前被压缩到一个小尺寸，以形成当前扩展的宇宙。威廉·莱恩·克雷格（William Lane Craig）和詹姆斯·辛克莱（James Sinclair）认为，如果熵在弹跳时达到最低限度，正统的解释是不正确的。他们认为，宇宙之间的界面代表了两个扩展的宇宙的诞生，即``double bang''而不是``大弹跳''。在这里，我回复了克雷格和辛克莱，以捍卫东正教解释。与它们的解释相反，一个宇宙的特征解释了另一个宇宙的特征，因此必须及时在另一个宇宙之前。此外，与克雷格（Craig）和辛克莱（Sinclair）的解释的关键部分相反，有一些弹跳宇宙学，即使熵在弹跳中``熵''，即使熵是``重置''，即使时间的热力学箭头是连续的。
On the orthodox interpretation of bounce cosmologies, a preceding universe was compressed to a small size before ``bouncing'' to form the present expanding universe. William Lane Craig and James Sinclair have argued that the orthodox interpretation is incorrect if the entropy reaches a minimum at the bounce. In their view, the interface between universes represents the birth of two expanding universes, i.e., a ``double bang'' instead of a ``big bounce''. Here, I reply to Craig and Sinclair in defense of the orthodox interpretation. Contrary to their interpretation, features of one universe explain features of the other universe and so must precede the other universe in time. Moreover, contrary to a crucial part of Craig and Sinclair's interpretation, there are bounce cosmologies in which the thermodynamic arrow of time is continuous through the bounce even though the entropy is ``reset'' at the bounce.
