PokeScience: Wailord is lighter than air?

So everyone knows what the largest pokemon is, Wailord, the massive leviathan of a pokemon that towers over all other pokemon. At a massive 14.5m (47'07") it would be the 6th largest animal (on physical dimensions) if it existed on our planet (beaten by 5 species of whale).




So surely this must be the heaviest pokemon as well? I mean, humpback whales are a very similar size and they weigh around 35 metric tonnes (80000 pounds).

Well no.
It barely scrapes the top 10.
There are 9 other pokemon (10 if you count primal Kyogre) that have more weight than this behemoth of a whale.
Weighing in at just 398kg (877.4lbs), Wailord is impossibly light.
But just how light is it? Could it even swim?

Warning, Science and Math ahead

Now, we have enough information to estimate the volume of a Wailord. We know it's mass and it's length and can estimate other dimensions from these measurements.

Now, pokemon only gives us one dimension of length in the pokedex, labelled height. Now I'm going to assume that this refers to the longest length of Wailord, giving it the specs of a whale which it is based off. Therefore, the length from nose to tail is 14.5m.

Now, from comparative measurements from pictures, I found a ratio of about 2.54 from height to length, giving it's other dimension as 5.71m

We can estimate Wailord as an ellipsoid (a 3D oval, pill, blimp shape), we can estimate it's volume to be about 247.54 cubic metres. [V=(4/3)(pi)abc].

Density = mass/volume, therefore we can calculate that density = 398/247.54
density = 1.61kg/cubic metre.

Now, for an object to float or sink in water, it's density must be less than or greater than the density of water respectively.
So if we have lead which is far more dense than water, it will sink, while a filled balloon which has less density that water will actively float and may be difficult to submerge.
The density of water at 20°C is 998.21 kg/m3. Which means, not only will Wailord float, it is almost impossible to submerge.

For that matter, lets check in on the density of air.
Air has a density of around 1.207kg/m3 at 20°C, which means our Wailord will almost float in air. However, consider that we have made a pessimistic estimation of Wailord's volume. Wailord is not an ellipsoid but is more like a cylinder with rounded ends.

If, instead we use the same dimensions but use a cylinder as the base shape (giving us an overestimated optimistic volume). We get Wailord's volume to come out as 371.3m3 and therefore his density as 1.07kg/m3. Therefore, Wailord's real density lies somewhere between these numbers and quite potentially, Wailord may be less dense than air.

I guess that's what you get from the float whale pokemon!

Now, lets quickly assume that height is the other dimension and therefore Wailord is 36.83m long making it larger than a blue whale. It's ellipsoid density is 0.0982 and it's cylinder density is 0.0654.
To put that in perspective, the least dense thing on our planet is hydrogen gas and that has a density of 0.082 meaning that Wailord could very well be less dense than hydrogen, and definitely less dense than air.

Hoenn Confirmed?

Well with the release of a few new Black and White 2 images, including the map, the internet has started talking and they believe there is going to be a Hoenn in the new games.

First, lets have a look at the map differences revealed so far.

So far, apart from the bottom left, it doesn't look like there are any major changes to the map, of course, most of the map has been covered in ice to hide the new things Nintendo doesn't want you to see, much the same way they used clouds on other maps to hide areas.

One of the speculations is about the ice itself, it seems to cover the edges of the map. Some people are saying that the ice is covering some of the transition areas between this region and the next.

So far there has been the release that the regional dex will have 300 pokemon, the most of any regional dex to date. I think this helps the speculation. I think that 300 pokemon in one region does sound a little compressed and one way they could spread out the species would be to expand the playable area, ie. Hoenn.

One thing to remember in this is that the gen 3 games (R/S/E) occurred in the same timeline as the gen 1 games, then several years later we have gen 2 and gen 4 occurring side by side and then finally we have the first two gen 5 games several years after that. The new games are set to take place a few years after the prequels, therefore, there is a massive time gap since we last saw Hoenn. Can you imagine going back after all this time, the changes that would have happened would be massive.

Remember that airport in Mistralton City?
That single airport?
It looks like that is a new airport on the mountain at the right of the new map. But why else is it there? Why do we need a plane to where we can fly to? Speculation says it will take us to Hoenn (much like the magnet train took us between Kanto and Johto.), which by now may have an airport of it's own. Although, I'm thinking it's more likely that this will take us to the battle frontier or some small island rather than a region.

A direct quote from Black and white after you find all the Seven Sages for Looker: "On a topic I must speak to you. Having received such a report, of someone far from here, who has seen a person like N and...a dragon Pokémon. I am on my way to verify the veracity of this information. We will meet again one day!"It appears that N has traveled to a different region with the legendary he has captured, could he have traveled to Hoenn?
