I bet you thought Godzilla was godzilla-sized. Well, you are wrong. Godzilla is BIGGER THAN GODZILLA. Check out the new poster from the next version of Godzilla movie.

That's a big Godzilla. BIG. io9 has an interesting post that includes a graphic of the size of Godzilla as a function of year. Of course, the exact size of Godzilla is difficult to determine, so most of the times it's just an estimate. In fact, the Wikipedia page on Godzilla has a short discussion of the inconsistent size of Godzilla.

How Big Will Godzilla Be in the 2025 Movie? ——————————————-

Instead of re-estimating the Godzilla sizes, let me just start with the values posted in the io9 graph. From that, get the following plot.

These are mostly guesses for the years. I could have looked up the actual movie dates, but I'm too lazy. So, this is just an approximation of Godzilla's size not the size of the actual and REAL Godzilla.

Actually, I plotted the natural log of height as a function of time. Why? Well, this is a more generic plot that I can then add a linear function to. Otherwise, I am assuming that Godzilla grows linearly with time. Why would anyone think that? And yes, I cheated. You can't take the natural log of "50 meters". Really this is the natural log of the height per meter (so that the stuff inside has no units).

Now, when I fit a linear function to this data I get the following (where a and b are the fit parameters from plotly).

That's it. I have a, I have b so I get use this function to get the Godzilla height for any year. Now, let's just plug in the year of t = 2025 (yes, t is in years). This gives:

That is 121.6 meters but I left off the meters because of my mathematical cheat above. Yes, that's not so big. The reason is that although the 2014 Godzilla is 140 meters, this is bigger than the other trend. Really, it's too big. A better value would be around 100 meters (this is based on the fit that includes the 140 m height though).

What about the year 2050? In this year, Godzilla would be 170 meters tall. Also, in this year Godzilla 2050 will be in 3D and include the much anticipated smell-o-vision (we have been promised this since the 1960s).

Of course having a ginormous Godzilla brings in other problems. Big things aren't the same as small things. If you double the height of an object, but keep the same shape you will increase the mass by a factor of 8.
