The Eater of Worlds. Despite being given this epic moniker since
literally the inception of the game, the Eater of Worlds has never actually been able to
eat worlds. Even his lesser spawn, the Eater of Souls,
manage to live up their name - as really annoying flying enemies they are pretty good at eating
your soul. However, the head honcho himself doesn't actually
eat worlds, because the developers never gave him the ability to destroy blocks. But, let's say the Eater of Worlds could actually
"eat" worlds, and destroy blocks. How long would it take for it to eat a world,
and would it be any good at it? Well, let's see. Firstly, let's define "eat". By saying the Eater of Worlds "eats" something,
we say that the Eater of Worlds can basically destroys ("eats") every block that comes into
contact with the front of his head. After all, that's where his one and only mouth
is. A world is completely "eaten" when the entire
world is gone, and every block has been graciously devoured by our wormy friend. So, essentially, the problem boils down to
looking at how long it'd take for the Eater to touch every part of the world with his
head. In order to do that, I need to know how fast
the Eater of Worlds moves. Problem is, the Eater is very hard to measure
in terms of speed, since he speeds up and slows down a lot, especially in the air. To solve this, I created a world entirely
made of Ebonstone, where I can observe the Eater tunneling in ideal conditions. After making a small air gap so that he could
actually spawn, I lead him away and turned noclip on so that I could go through blocks,
much like him. My goal is to see how long it takes him to
reach me in the center of the screen from the edge of the screen, which would allow
me to calculate his speed. There we go. From that recording, that time would be 78
frames, or 1.3 seconds. Specifically 78 frames from the edge of my
screen to this line on my wings right here, which if we measure in-game comes out to 58
2/3 blocks, since that one block right here doesn't count. That makes out to be about 45.13 blocks per
second, 90.26 feet per second, or about 165,354 furlongs per fortnight. For the metrically enlightened, that's 27.5
meters per second or right around 99 kilometers per hour - roughly highway speed in most countries. I'll also round this 99 up to a nice even
100 kilometers per hour to account for possible measuring error as well as the fact the Eater
might not be perfectly straight in my observations. These calculations are by no means going to
be perfectly accurate, but we don't need microscopic precision anyway, so that's fine in this scenario. So, knowing that the Eater of Worlds' head
is 23 pixels or 1.75 meters wide, that means at 100 km/h the Eater is able to cover an
area 1.75 meters x 100 km wide in one hour of eating. That's 175,000 square meters of eat per hour. Meanwhile, a large Terraria world filled in
with blocks has an area of 7,491,701.1456 square meters if you include out of bounds
areas, meaning that this would theoretically take the eater around 42 hours and 48 minutes
to eat an entire Large Terraria world, if it were entirely filled in. Since most Terraria worlds are not entirely
filled in, it would generally take less time. For example, a world that is, say, 80% filled
in, would only take 34 hours and 14 minutes to eat. And that's counting all those redundant caves
he has to pass through without eating anything. I also haven't yet counted all the corners
he has to make. After all, he's not just moving in a straight
line and eating, he has to turn at the world border because our Terraria world is both
flat and bounded. To say the Eater is quite slow at turning
around would be an understatement, and he has to slow down quite a lot to make a 180
degree turn. If he takes a zigzag pattern, the amount of
turns he has to take at the world border equals the height of the world divided by his own
width, and in this case, that equals 836 turns. If we assume the Eater is a slow bastard and
each turn takes him around 3 seconds, that's another roughly 2,500 seconds we have to add
to his time, making the worst case scenario for him 43 hours and 30 minutes, and the 80%
filled scenario (which also has 80% the turns) take 32 hours and 47 minutes. Essentially, the answer to this question for
a Large Terraria world is somewhere between 1.3 days and 1.8 days in real life time, depending
on how full the world is. Seems fast, right? Well, if we convert this real life time value
to Terraria time, which the Eater would presumably live on, then we get a number from 78 days
to 108a days. So, a few months. Honestly, that's quite slow, actually. Compared to the Eater of Souls, who take mere
seconds or Terrarian minutes to feast on a soul, the Eater of Worlds takes days or Terrarian
months to do so. What's even sadder is that Terraria's "world"
isn't even the "world". If you go to the ocean, you can see other
islands off in the distance. So, your world isn't really a "world", more
than it is just an "island". But I guess "Eater of Islands" doesn't sound
as cool as "Eater of Worlds". It would probably take the Eater of Worlds
a literal eon to eat an actual world, like the Earth, a object slightly larger than a
Terraria world. Also, actual worlds like the Earth are 3D,
and the Eater of Worlds either 2D or of of unknown thickness, so it's basically impossible
to say how long it would take for him to eat an actual world. But all of this is just a theoretical calculation. Back in reality-land, it can't even destroy
blocks, nor the world that you give it. It's not even an "Eater of Islands", like
I said before, it's an Eater of Nothing. No wonder some shortie in a tin can can defeat
it using some bottles of dollar store liquor. If there's anything to learn about the Eater,
it's that it really needs to get good. Because it kinda sucks. At its job. Hello, if you enjoy my content, a subscription
