這是一個極其動人且充滿哲學意涵的組合。
貝多芬的**《降B大調第13號弦樂四重奏，作品130》第五樂章〈抒情短歌〉（Cavatina），不僅是貝多芬晚年最珍視、甚至曾邊聽邊流淚的作品，它也被正式選入了隨旅行者二號**（Voyager 2）飛往外太空的**「航行者金唱片」**（Golden Record）中。
這首曲子與這艘太空船的結合，被譽為「人類送給宇宙最深沉的一封情書」。
1. 為什麼是這首曲子？
在金唱片的 27 首樂曲中，這首〈抒情短歌〉被安排在最後，作為壓軸曲目。當時的負責人、天文學家卡爾·薩根（Carl Sagan）與其團隊認為，這首曲子最能代表人類情感中的「孤獨與渴望」。
痛苦中的昇華： 貝多芬在創作此曲時已完全失聰，深陷孤獨。樂譜中有一段標註為 "beklemmt"（意為「沉重、窒息、痛苦」），小提琴的旋律像是人在哽咽、斷斷續續地哭泣，但隨後又展現出一種超脫塵世的平靜。
靈魂的自白： 貝多芬曾對朋友說，這首曲子是他寫過最令他感動的音樂，「光是回想旋律都會讓我流淚」。
2. 旅行者二號：漂泊在外的孤獨觀測者
旅行者二號於 1977 年發射，它在 2018 年正式穿過了日球層頂（Heliopause），進入了星際空間。它現在與地球的距離超過了 200 億公里。
當這首曲子隨著旅行者二號在冰冷、真空、無聲的宇宙中穿行時，它產生了一種強烈的對比：
極度的孤獨： 貝多芬在失聰的寂靜中寫下這段旋律，而這段旋律現在正處於宇宙真正的寂靜中。
永恆的生命： 雖然旅行者二號的電力預計在 2020 年代後期耗盡，屆時它將成為一顆漂流的「死星」，但這張金唱片即便過了 10 億年，依然能保持完好。
3. 跨越時空的訊息
如果有一天，外星文明攔截了旅行者二號並播放了這張金唱片，當他們聽到這首〈抒情短歌〉時：
他們聽到的將不是人類的科技成就（如數學或物理公式），而是人類這個物種最脆弱也最美麗的時刻。他們會知道，在銀河系的某個角落，曾有一群生命透過悲傷與平靜，去理解宇宙的廣大。
總結：一種「星際式的浪漫」
這首曲子就是人類靈魂的代碼。當旅行者二號飛向遙遠的恆星系時，它帶著貝多芬的眼淚與希望。正如卡爾·薩根所說，這張唱片是我們投向宇宙深處的一封「瓶中信」，而這首〈抒情短歌〉就是信中最溫柔的落款。
That is a beautiful and poetic connection. When we talk about Voyager 2 (旅行者二號) and its journey into deep space, we are talking about one of humanity's greatest "messages in a bottle."
Since you mentioned a "music piece" in relation to Voyager 2, you are likely referring to the Golden Record, or perhaps the famous "Dark Was the Night, Cold Was the Ground" by Blind Willie Johnson, which is often cited as the most hauntingly beautiful track representing human emotion on that craft.
The Loneliest Concert in the Universe
Voyager 2 was launched in 1977. Tucked inside is a 12-inch gold-plated copper disk containing sounds and images selected to portray the diversity of life and culture on Earth.
If an extraterrestrial civilization ever finds Voyager 2, the "music piece" they hear will be our legacy. Here is how that music connects to its journey:
The Selection: The record includes everything from Bach and Beethoven to Chuck Berry and traditional music from around the world (including Chinese guqin music, "Flowing Streams" / 《流水》).
The Purpose: It wasn’t just to show we are smart; it was to show we have soul. The music acts as a bridge across the vacuum of space, expressing feelings that math and physics cannot.
The Journey: Voyager 2 is currently in interstellar space (the space between stars). It passed the heliopause in 2018, meaning it has left the "bubble" of our sun and is drifting in the true dark of the cosmos.
Why this Music Matters Now
As Voyager 2 moves further away (it's currently over 20 billion kilometers from Earth), its power sources are slowly fading. Eventually, the craft will go "silent" and stop transmitting data to NASA.
However, the Golden Record will last for billions of years. Even after our sun dies and the Earth is gone, that music piece will still be out there, etched in gold, traveling through the stars.
"The spacecraft will be encountered and the record played only if there are advanced spacefaring civilizations in interstellar space. But the launching of this bottle into the cosmic ocean says something very hopeful about life on this planet." — Carl Sagan
A Shared Sentiment
Whether the music is a grand symphony or a lonely blues guitar, it represents a "hello" from a small blue planet to the vast unknown. It makes the coldness of outer space feel a little warmer.
