Is It Scientifically Possible for Godzilla to Exist?

Thanks to the newest iteration of the Godzilla franchise, there's been quite a bit of chatter recently about everyone's favorite giant, murderous lizard. But isn't being able to take on the beast a moot point if he can't technically exist in the first place? Thanks to a little help from science, Vsauce has our answer.


As it turns out, Godzilla would be way more high maintenance in real life than he seems on screen—even by actors' standards. Taking account for his size, Godzilla would need about 215 million calories a day. And with one human only supplying about 110,000 of those calories, he wouldn't just need one measly human to satisfy his hunger; he'd need about 2,000 of them. Which, as Jake Roper points out, would increase the human mortality rate by a good 1.3%.

It's not just his ravenous appetite that could cause problems, it's the body all those calories would be fueling. Because at 90,000 tons, Godzilla would weigh the same as a little over half of all the gold that humanity has ever mined. In other words, the second Godzilla emerged from his watery lair, gravity would crush him like a little glass bug. No military required. [Vsauce3]

What is the maximum size for a creature before bone couldn't support it? I believe the only way a creature could become that large, and still be able to support itself without buoyancy, would be an exoskeleton with multiple legs - probably like a centipede.. but I think the only reasonable way an organism could grow that large is if it were a culture, like a single large fungus or blob
