Regina Barber: 我认为虫洞是科幻作品中一个非常吸引人的概念，它基于爱因斯坦的广义相对论，为我们提供了一种在宇宙中快速旅行的可能性。虽然我们还没有直接观察到虫洞，但理论上它们是存在的，并且可能连接着黑洞和白洞，形成宇宙中的快速通道。如果真的发现了虫洞，那将是一个非常令人兴奋的发现，可能意味着我们找到了其他文明存在的证据。 Ron Gamble: 作为一名理论物理学家，我认为虫洞是广义相对论的一个有趣的解，它描述了时空本身的弯曲。虫洞就像一个地铁隧道，通过超空间连接着宇宙中遥远的两点。虽然虫洞的存在需要奇异物质，这使得它们难以自然形成，但我们不能排除它们存在的可能性。研究虫洞不仅可以帮助我们更好地理解宇宙的结构，还可以激发我们对未来技术的想象。我始终认为，即使我们现在无法测试虫洞，但研究它们仍然具有重要的意义，因为曾经的许多科幻概念，如太空旅行和手机，都成为了现实。

Chapters
This chapter introduces wormholes as a possible solution to Einstein's equations, explaining their function as theoretical cosmic portals that could shorten long space trips. It uses the analogy of a folded paper with a hole to illustrate the concept.
  • Wormholes are a possible solution to Einstein's equations.
  • They are theoretical cosmic portals that can shorten space travel.
  • They can be visualized as a connection between two points in space-time.

In science fiction, wormholes are hyperspace subway tubes linking one part of a galaxy directly to another, distant point. But could they actually exist? To find out, we talk to theoretical physicist Ron Gamble), who says wormholes aren't just a matter of science fiction — and they have big implications about the shape of space itself.*Want to hear about more hypotheticals physicists have to confront in their work?
