量子力学、引力与多元宇宙

Quantum Mechanics, Gravity, and the Multiverse

Yasunori Nomura

摘要:

宇宙加速膨胀的发现使我们产生了一种戏剧性的观点,即我们的宇宙可能是低能物理定律以不同形式存在的众多宇宙之一:多元宇宙。我解释了为什么/如何在观测和理论上支持这个观点,特别是弦论和永恒暴胀。然后,我描述了量子力学如何在理解多重宇宙中发挥至关重要的作用,即使是在最大的距离尺度上。由此产生的图像导致了我们对时空和引力的看法的革命性变化,并将永恒膨胀的多元宇宙的范式与量子力学的多世界解释完全统一起来。这幅图还为永恒暴胀中一个长期存在的问题提供了一个解决方案,这个问题被称为测度问题,我简要地描述一下。

英文摘要:

The discovery of accelerating expansion of the universe has led us to take the dramatic view that our universe may be one of the many universes in which low energy physical laws take different forms: the multiverse. I explain why/how this view is supported both observationally and theoretically, especially by string theory and eternal inflation. I then describe how quantum mechanics plays a crucial role in understanding the multiverse, even at the largest distance scales. The resulting picture leads to a revolutionary change of our view of spacetime and gravity, and completely unifies the paradigm of the eternally inflating multiverse with the many worlds interpretation of quantum mechanics. The picture also provides a solution to a long-standing problem in eternal inflation, called the measure problem, which I briefly describe.
