A mathematician recently calculated that eBook readers "gain weight" when you add new books to your library. Now a YouTube science channel has used the same mathematics to calculate the mass of the entire internet.
Surprisingly, the whole thing weighs just 50g - around the weight of a single (large) strawberry.
But the actual information in it weighs less than a speck of dust.
Vsauce says that the 50g figure is the weight of all the electrons in the electricity required to make the internet work - assuming 75-100 million servers supporting the internet, and not including the home PCs running it.
The whole lot equates to around 40 billion watts - which weighs in around the same as a plump strawberry.
If you include all the home PCs using the net, the figure is roughly three strawberries.
The weight if you're just counting the data stored in the internet is much less.
The entire weight of that information would work out, Vsauce estimates, to 0.02 millionths of an ounce.




据英国《每日邮报》11月3日报道,近日,一位数学家计算出当往电子书阅读器中添加新文档时,阅读器会增重。现在YouTube 的一个科学频道利用同样的运算方法算出了整个互联网的重量。

令人惊讶的是,整个互联网的重量仅有50g,相当于一颗大草莓的重量。
但网络包含的实际信息的重量却不及一粒灰尘。

Vsauce(YouTobe科学频道)说假设不包括家用个人电脑,有7500万至1亿台服务器在支持网络运营,这个50g的数据就是互联网工作时所需要电力的重量。

整个互联网的用电量相当于400亿瓦特左右,换算成质量的话和一颗饱满的草莓称重差不多。

如果算上所有使用网络的家用个人电脑,互联网的重量就大约等同于三颗草莓。
如果仅仅计算互联网上所贮存的数据重量,得到的数据就会小很多。
Vsauce估计,互联网所包含的信息重量等同于一盎司(约28g)的五千万分之一。
