论文摘要
这是计划中的专着“无处不在：量子重力理论中时空的出现”的一章，由尼克·休格特（Nick Huggett）和克里斯蒂安·瓦特里奇（ChristianWüthrich）合着，并与牛津大学出版社（Oxford University Press）合同。 （更多信息，请访问www.beyondspacetime.net。）本章介绍了因果集理论，并在该理论中识别和阐明了“空间问题”。
This is a chapter of the planned monograph "Out of Nowhere: The Emergence of Spacetime in Quantum Theories of Gravity", co-authored by Nick Huggett and Christian Wüthrich and under contract with Oxford University Press. (More information at www.beyondspacetime.net.) This chapter introduces causal set theory and identifies and articulates a 'problem of space' in this theory.
