  • Spider-man has some pretty sweet abilities, but let us take a scientific look to see how well this superhero stacks up to reality.

    蜘蛛人有一些很讚的能力,但讓我們從科學的角度看看這位超級英雄跟現實相符的程度。

  • For Spider-man to become genetically modified, the spider that bit him would have to release a retrovirus into his body.

    為了修改蜘蛛人的基因,咬他的蜘蛛必須在他身體中釋放出一種反轉錄病毒。

  • Retroviruses carry genetic information which gets inserted into the DNA of cells.

    反轉錄病毒攜帶著基因資訊,嵌入細胞中的DNA。

  • The cell then reads the new DNA to create specific functions and proteins for that cell.

    接著細胞會讀取新的DNA而產生特殊功能和蛋白質。

  • But this retrovirus would have to make its way to nearly every cell and have the ability to code for new and different functions in each cell.

    然而這反轉錄病毒得散布到每一個細胞,而且還要能細胞中為不同的新功能編碼。

  • So while it's theoretically possible, it would also be pretty "amazing".

    所以儘管理論上來說是有可能的,它依然非常「神奇」。

  • Silk: it's actually proportionately stronger and more flexible than steel.

    絲,其實按比例來說它比鋼鐵更堅固、柔韌。

  • Spider webs, one tenth the size of a piece of hair, are able to catch insects flying upwards of 15 miles an hour.

    蜘蛛網,尺寸是頭髮的1/10,可以抓住以15英里(24公里)時速向上飛的昆蟲。

  • And, believe it or not, if a web were an inch thick in diameter, it could actually stop a fighter jet.

    而且,信不信由你,如果蜘蛛網的直徑有一英吋(2.54公分)厚,它其實可以攔下一架噴射戰鬥機。

  • Strength: some spiders can lift up to 50 times their body weight. This muscle strength is directly related to size.

    力量,有些蜘蛛能舉起比自己重50倍的東西, 這樣的肌力跟尺寸有直接的關係。

  • Think about your bicep. When you work out, it increases in height and width but not length.

    想想看你的二頭肌,當你健身時,它會增加高度和寬度,而不是長度。

  • In this way, the strength of an organism increases as a square, or by 2 on the scale factor.

    這樣一來,生物的力量是以二次方、或是二度空間比例尺增長。

  • But as organisms get bigger, their volume increases in height, width and length, as a cube, or by 3 on the scale factor.

    但是當生物變大,它們的體積在高度、寬度和長度上,以三次方、或是三度空間比例尺增長。

  • This creates a ratio of 2:3, meaning the bigger the organism, the smaller its proportional strength.

    這形成 2:3 的比例,意思是生物越大,相對力量就越小。

  • But because Spider-man is human shaped and sized, the retrovirus would have to encode for the creation of more actin and myosin proteins.

    但因為蜘蛛人具有人類的外型和尺寸,反轉錄病毒得編碼創造出更多肌動和肌凝蛋白。

  • These proteins affect the contraction abilities of muscles, and in effect could make a human stronger.

    這些蛋白影響肌肉收縮的能力,還能有效地強化人體。

  • Climbing walls? Not a problem for spiders, they have tiny hairs on each leg.

    爬牆?對蜘蛛來說是小菜一疊,它們每隻腳上都有細毛。

  • And these hairs have tons of even smaller hairs with triangular ends, which interact within nanometers of the atoms on the surface.

    而這些毛上還有無數更細的毛,末端呈現三角狀,它們和物體表面幾奈米大小範圍內的原子相互作用。

  • This creates electrostatic forces, allowing them to stick with a strength of 170 times their own weight.

    這會產生靜電力,讓它們能以自身重量 170 倍的力量黏附上去。

  • To capture this ability, Spider-man would need permanently hairy hands and feet, which may not overly impress his damsels in distress.

    想要獲得這能力,蜘蛛人永遠需要「毛手毛腳」,這可能不會讓等待救援的少女留下好印象。

  • And finally, what about the Spidey Sense?

    還有最後一點,「蜘蛛感應」呢?

  • Well, spider hairs are extremely sensitive to vibration and air pressure changes.

    蜘蛛的毛對震動和氣壓的改變極度敏感。

  • But this means that Spider-man could only perceive things that are near him, and not events at a distance.

    但這意味著蜘蛛人僅能感知到身邊的東西,而不是遠方的事件。

  • Got a burning question you want answered?

    你有燃眉之急的問題想要答案嗎?

  • Ask it in the comments, or on Facebook and Twitter, and subscribe for more weekly science videos.
