Topics
Neil deGrasse Tyson: 本期节目讨论了《星际迷航》中的科技设定,其中一些设定,例如自动门,在当时看来并不令人信服,而其他一些设定,例如通讯器和三录仪,则更具未来感。科技发展并非线性,而是呈指数级增长,因此预测未来科技发展趋势存在困难。在《星际迷航》中,大部分星际旅行发生在银河系内,宇宙膨胀对星际旅行的影响可以忽略不计。根据爱因斯坦的相对论,任何物体都不能超过光速,但通过弯曲空间,可以实现超光速旅行,但这在能量需求上存在巨大挑战。科幻作品不仅反映了现实的挑战,也代表了对未来的美好憧憬,并激励人们为创造更美好的未来而努力。 Charles Liu: 《星际迷航》激发了人们的想象力,促使人们去设想未来可能实现的技术,例如超光速旅行、远程通讯和自动门。在《星际迷航》中,自动门是当时最难以置信的未来科技。一些科技设定是为了叙事方便,而非基于科学的合理推测。曲速引擎的概念是《星际迷航》中一个重要的科技设定,它暗示了超光速旅行的可能性,但同时也引出了许多科学上的难题。爱因斯坦的广义相对论提供了超光速旅行的数学可能性,但实现它需要克服巨大的能量障碍。反物质可以通过磁场进行约束,防止其与物质接触发生湮灭。目前许多《星际迷航》中展现的科技需要我们尚未理解的物理学原理来实现。在未来200年内,实现《星际迷航》中描绘的大部分先进科技的可能性很低。 Chuck Nice: 在《星际迷航》中,瞬时通讯技术在原剧中并未得到解释,但在后续系列中引入了亚空间通讯的概念。阿尔库别雷曲速引擎的概念在科学界引起了兴趣,但也受到了科幻作品的广泛运用。《星际迷航》中一些科技设定,例如相位器,在科学上存在不合理之处,需要进行后设解释。小型设备的能量来源,例如相位器,在剧中并未得到合理的解释,电容器可以快速释放大量电能,这可能是小型设备能量来源的一种可能性。

Deep Dive

Key Insights

Why did Star Trek's creators introduce the concept of warp drive instead of simply saying they traveled faster than light?

Star Trek's creators respected Einstein's theory of relativity, which prohibits objects from traveling faster than light. Instead, they introduced the warp drive concept, which warps space-time, allowing faster-than-light travel without violating the speed limit.

What year does the original Star Trek series take place in?

The original Star Trek series is set around the year 2260, approximately 200 years in the future from when the show was created.

What technological advancements from Star Trek have already become reality?

Several technologies from Star Trek, such as tablet computers, handheld communicators (like smartphones), and telepresence (video calls), have already become part of our daily lives.

What is the significance of dilithium crystals in Star Trek's warp drive technology?

Dilithium crystals are essential in Star Trek's warp drive technology as they regulate the matter-antimatter reactions necessary for faster-than-light travel. They ensure the energy produced is stable and controllable.

How does the transporter technology in Star Trek work, and why was it introduced?

The transporter was introduced to avoid the time-consuming process of landing and taking off from planets. It allows characters to instantly move from one location to another by disassembling and reassembling their molecules, though the exact science behind it was never fully explained.

What is the Alcubierre warp drive, and how does it relate to Star Trek's warp technology?

The Alcubierre warp drive is a theoretical concept where space-time is warped to allow faster-than-light travel without breaking the speed limit. It involves pulling space behind a ship and pushing it in front, similar to how Star Trek's warp drive operates.

How does antimatter containment work in Star Trek, and why is it necessary?

Antimatter must be contained in a magnetic field to prevent it from annihilating with matter. A magnetic bottle, created by a charged magnetic field, keeps antimatter suspended without direct contact, ensuring it doesn't interact with surrounding matter.

What percentage of Star Trek's futuristic technology do Neil deGrasse Tyson and Charles Liu believe will be realized by the year 2260?

Neil deGrasse Tyson predicts that only about 1% of the futuristic technologies depicted in Star Trek will be realized by the year 2260, based on current scientific understanding and technological progress.

Why did Star Trek's creators avoid calling their handheld communication devices 'lasers'?

The creators avoided using the term 'laser' because they wanted to future-proof the technology. Lasers were already a known technology at the time, and they wanted to create something more futuristic and distinct.

What is the significance of the mycelium network in Star Trek: Discovery, and how does it relate to real-world science?

The mycelium network in Star Trek: Discovery is inspired by real-world mycology, the study of fungi. It represents a vast, interconnected network similar to the mycelium found in mushrooms, which plays a role in the show's plot for communication and transportation.

Shownotes Transcript

Could we create warp drive someday? Neil deGrasse Tyson and co-host Chuck Nice team up with astrophysicist Charles Liu to dive into the science, technology, and legacy of one of the most influential sci-fi franchises of all time: Star Trek.
