科学拓展了我们对现实的认知 Science Expands Our Vision of Reality
多重宇宙理论正是这一趋势的又一重要进展 The multiverse is another step in this direction
布雷特：许多科学家和哲学家都曾探讨过多重宇宙的概念，但我们讨论的是一个严格而严谨的理解——这个多重宇宙是什么？
Brett: Many scientists and philosophers have talked about the concept of a multiverse. But we’re talking about a very strict, very sober understanding of what a multiverse is.
这个多重宇宙中的所有宇宙都遵循相同的物理定律。我们讨论的不是存在不同物理法则的宇宙，而是基于现有认知的扩展。
All of these universes in this multiverse obey the same laws of physics. We’re not talking about universes where there are other laws of physics.
过去我们认为宇宙中的一切——其他行星、恒星、太阳、月亮——都在围绕地球运转，而人类只是这颗小小星球上的居民。
We used to think that everything in our universe—other planets, stars, the sun, the moon—orbited around us. We existed on this tiny planet.
接着我们的认知逐渐扩展，意识到太阳才是宇宙中心，同时发现太阳与木星、土星等气态巨行星的体积远超地球。于是宇宙的规模被无限拉大
Then our vision of reality got expanded a little bit. We realized that, in fact, we were not the center of the universe—the sun was the center. We also realized the sun and some of the other planets—Jupiter, Saturn and the other gas giants—were bigger than our planet. So our universe became larger.
接着我们意识到自己不过是浩瀚星系中的一颗，再后来这个星系是数千亿个星系中的一个。
Then we realized that we were just one star system among many in a huge galaxy of hundreds of billions of stars. Later we realized that this galaxy is one of hundreds of billions of galaxies.
思想与科学的发展史，本质上是人类不断拓展对物理现实广度认知的历程。
The history of ideas and science is a history of us broadening our vision of exactly how large physical reality is.
多重宇宙理论正是这一趋势的延续，我们有理由相信这种认知将持续深化。要让人们接受这种理解方式并不难。
The multiverse is another step in that general trend, and we should expect it to continue. It shouldn’t be that hard for people to accept that this is the way to understand things.
难道我们已经完全掌握了量子理论和多重宇宙的运作机制？答案显然是否定的。多重宇宙尚未与广义相对论完美统一，我们仍需构建其时空结构或几何体系。
Do we know everything about quantum theory and how this multiverse works? No. We haven’t united the multiverse with general relativity. We still need a space-time or a geometry of the multiverse.
马丽：随着科学的发展，人类认知到宇宙是无穷的，是无限大的。人类不过是这个虚无空间中的一粒尘埃，作为一颗尘埃，也有他/她的蝴蝶效应，在我思故我在的存在价值观众，只要我们思想在颤动着它的翅膀，无限大的宇宙也会随着这个微小的振动而产生多米诺效应。
此刻，我竟然想起中学时，那些阳光温暖的周末，阅读过的那本书《约翰.克里斯多夫》。思想是多么奇妙。
