论文摘要
时间,空间和物质是我们推理的类别,其属性似乎是基本的。但是,这些需要进行审查,就像原始宇宙的极端状态一样,这些当前的量子特性。量子的时间意味着什么?这对太空意味着什么?空间和时间消失了吗,或者消失的只是我们一直在用来理解它们的类别?因果结构的叠加或空间的量子粒度等概念需要我们的注意,应澄清以了解原始宇宙的物理学。这带来的新颖性需要我们反思物质:在颗粒空间上如何定义物质?量子重力是否暗示我们要考虑新类型的物质?这些问题的答案,即触及物理基础的基础以及我们组织对现实的理解的概念,在与自己面对经验数据的过程结束时需要。为此,宇宙本身为我们提供了最好的实验室。
Time, space, and matter are categories of our reasoning, whose properties appear to be fundamental. However, these require a scrutiny as in the extreme regime of the primordial universe these present quantum properties. What does it mean for time to be quantum? What does it mean for space? Are space and time disappearing, or what is disappearing are simply the categories we have been using to understand them? Concepts such as the superposition of causal structures or the quantum granularity of space require our attention and should be clarified to understand the physics of the primordial universe. The novelty that this brings requires us to reflect on matter as well: How can matter be defined on a granular space? Is quantum gravity hinting us toward considering new types of matter? The answers to these questions, that touch the foundations of physics and the very concepts with which we organize our understanding of reality, require in the end of the journey to confront ourselves with empirical data. And for that, the universe itself provides us with the best of possible laboratories.
