    想像一隻方塊牛,活在方塊山丘上,在方塊雲之下,

  • Consider a cubic cow, living on a cubic hillside, under cubic clouds, on a cube

    在這方塊世界裡。Minecraft星球是否可能存在?

  • world. Could planet Minecraft actually exist?

    發行超過七千萬份、擁有超過一億玩家,Minecraft世界

  • [MUSIC]

    極其巨大......但絕非無限。

  • With over 70 million copies sold and more than 100,000,000 players, the world of Minecraft

    由於電腦數學編碼的某種特性,整個Minecraft世界

  • is huge. But it’s not infinite.

    被限制在長寬約687億公尺,區域總共約包含4700兆

  • Thanks to some quirks of your computer’s mathematical code, the Minecraft Overworld

    平方公里,約是地球表面積的

  • is limited to a width of 68.7 billion meters, for a total area of 4.7 quadrillion

    九百萬倍。

  • square kilometers or about 9 million times the surface area

    當然這還只是一面。Minecraft星球的六面包括超過

  • of Earth.

    兩萬八千兆平方公里,超過太陽表面積的四千倍!

  • Of course, that’s just one face. All six sides would have an area of over 28 quadrillion

    當接近世界邊緣, 離任一張Minecraft地圖中心約三千萬公尺處,

  • square kilometers, more than 4,000 times the surface area of the sun.

    事情會變得相當古怪。所有東西都消失了。

  • Near the World Border, about 30,000,000 meters from the center of any Minecraft landscape,

    在方塊行星上確實有道理。重力被限制只能在每一面的

  • things start to get very weird. Living stuff just sort of disappears.

    中心朝下。當你越靠近任一道邊緣,越多的質量會在

  • On a cubic planet, this makes sense. Gravity would only be oriented straight up and down

    我們後頭的地底下,雖然這會讓重力到達邊緣時

  • at the center of each face. The closer we get to any horizon, the more of the planet’s

    因距離稍微減弱,我們卻會莫名感覺到像在爬坡。

  • mass that would be under and behind us, and although that would make gravity slightly

    這種有角度的重力會把空氣和水拉離邊緣。 從環繞行星的軌道上

  • weaker towards the edge, we’d get the odd sensation that we were walking uphill.

    看看我們的方塊星球, 會看到六個大氣層泡泡,位在每一面中央。

  • That angled gravity would end up drawing air and water away from the edges. Viewing our

    在表面上,我們只能不斷走動直到

  • cubic planet from orbit, we’d see six bubble atmospheres, one in the center of each face.

    掉進太空。

  • On the surface, we’d only be able to travel so far before we simply walked right out into

    啊,世上已無美景能夠與方塊夕照相比。不像地球,

  • space.

    這世界的日月運行只是簡單地保持在相反位置。

  • [MUSIC]

    那假想月球其實就是鄰近的立方星體,被鎖定在

  • Ah, there’s nothing quite as beautiful as a cubic sunset. Unlike on Earth, the Overworld’s

    和方塊太陽同步的軌道。但這無法解釋群星。

  • sun and moon are always oriented directly opposite of each other. One explanation is

    地球夜空中,眾星和月球的相對位置在每晚改變

  • that the Overmoon is actually a neighboring cubic planet, locked in its own synchronous

    因為繞太陽公轉之故。但在Minecraft,夜空永遠相同。

  • orbit with the Cubesun but that doesn’t explain the stars.

    這只能說方塊世界在該宇宙的中心,被互相鎖定的日月

  • In Earth’s night sky, the relative positions of the stars and moon change each night as

    和群星所環繞。顯然哥白尼不會是個死忠玩家。

  • we travel around the sun. But in Minecraft, the night sky always looks the same. This

    由於太陽和月亮每天都通過正頭頂,我們斷言方塊行星

  • can only mean the Overworld is at the center of its universe, orbited by a fixed sun, moon,

    的旋轉軸直接穿越其中兩面。

  • and stars. Clearly, Copernicus would not be a ‘crafter.

    這兩極面注定只能見到微弱暮光, 而它們的泡泡生物群系很可能是

  • Since the sun and moon pass directly overhead each day, we can conclude that the polar axis

    冰凍荒原,缺乏複雜生命。但其他多彩的面

  • of our cubic planet passes directly through the center of two of the six faces. These

    還能多生成三個各獨立的虛擬世界呢。

  • polar faces would only ever see dim twilight, and their bubble biomes are most likely frozen

    1884年某瑞士天文學家聲稱,發現了這種方塊世界,

  • wastelands, devoid of complex life. But the other illuminated faces of our world could

    在海王星外公轉。據透:他錯了。大錯特錯。

  • be home to three unique Overworlds of their own.

    向超人、畢沙羅和一切Minecraft玩家致上真誠歉意,

  • In 1884 a Swiss astronomer claimed to have discovered a cube world just like this, orbiting

    物理法則表示方塊行星和方塊鴨(雞) 很可惜,無法實現。

  • beyond Neptune. Spoiler: he was wrong. Very, very wrong.

    有足夠的重力迫使自己成為球形乃是行星的

  • With my sincerest apologies to Superman, Bizarro and Minecraft players everywhere, the laws

    其中一項標準。 重力會儘可能把一個物體的質量拉進最小的體積,而

  • of physics say cubic planets and cubic ducks are sadly impossible.

    儘可能使拉力平均發散。最佳形狀是什麼?

  • Having enough gravity to rearrange into a sphere is one of the criteria for being a

    球形。

  • planet. Gravity wants to pull an object’s mass into the smallest volume possible, and

    一顆氣體行星,如木星,大多由氫氣組成, 如果其質量比現在

  • to distribute that gravity as evenly as possible among that mass. The best shape for that? A

    多80倍,便不再是行星。其重力和內部壓力會高到

  • sphere.

    讓氫在其核心進行核融合而變成氦。

  • If a gas planet like Jupiter, made mostly of hydrogen, were just 80 times more massive

    它將成為恆星。

  • than it is, it wouldn’t be a planet anymore. Its gravity and internal pressure would be

    若岩石行星想成為恆星,為了融合更重的元素,如矽,

  • so high that elements like hydrogen would begin to fuse to helium at its core it

    它需要比太陽質量多8~11倍。

  • would turn into a star.

    我們的方塊世界體積是 3.2 x 10^23立方公里,且密度

  • For a rocky planet to turn into a star, to fuse heavier elements like silicon, it would

    接近地球,其整體質量近太陽的九十萬倍。

  • have to be about 8 to 11 times more massive than our sun.

    我們宇宙中唯一能夠匹敵的天體是......超大質量黑洞。

  • Our cube world’s volume would be 3.2 x 10^23 cubic kilometers, and at a density similar

    這些巨大的黑洞在大多數星系的中心都很容易找到, 環繞著不可勝數的

  • to Earth’s, its hexahedral mass would be nearly 900,000 times that of our sun. The

    熱能和輻射。一如所有黑洞,它們包含的質量

  • only things that massive in our universe are - supermassive - black holes.

    如此巨大,重力之強連光線都插翅難飛。

  • These large black holes are likely found at the center of most galaxies, surrounded by

    因此一個方塊世界在這個宇宙中

  • incredible amounts of heat and radiation. Like all black holes, they contain so much

    應該不可行,但若Minecraft有教我們任何事, 那就是它自身所在的宇宙。

  • mass, so much gravity, that even light can’t escape.

    在那裡,誰知道有什麼可能?保持好奇心吧。

  • So, a cubic Overworld might be impossible
