The Unlikely Battle: Ant-Man vs. Thanos

The concept of Ant-Man shrinking down and entering Thanos's body, and then expanding to defeat him, is a humorous and outlandish idea often discussed among fans of the Marvel Cinematic Universe (MCU). However, from a scientific perspective, this scenario has several significant issues.

Biochemical Realities and Challenges

The human body, including Thanos, is a complex system of cells, tissues, and organs. If Ant-Man were to shrink down and enter, he would face immense challenges navigating through the body without being attacked by the immune system or causing harm to internal organs.

Expansion Effects and Catastrophic Consequences

If Ant-Man were to expand inside Thanos, the sudden increase in size would likely cause catastrophic damage. The expansion would not only crush internal organs but also create a massive pressure differential that could rupture tissues, leading to immediate and fatal consequences for Thanos.

Physics of Shrinking and Expanding

The mechanics of how Ant-Man's Pym Particles work are fictional. In reality, if something were to shrink and then suddenly expand, the laws of physics would suggest that the energy released would be destructive. This indicates that Ant-Man's method of entering and exiting Thanos would be both dangerous and highly improbable.

Narrative Device: Entertainment Value over Scientific Plausibility

In the context of the MCU, this idea serves as a comedic plot device rather than a scientifically plausible strategy. The films often play with the absurdity of superhero powers for entertainment, making such scenarios a fun and exciting discussion among fans.

While it's a fun idea to think about, the scenario wouldn't work in a realistic context and fundamentally relies on the suspension of disbelief typical of comic book storytelling.

The Ultimate Duel: Antz Boi vs. Snappy Boi

Let's ignore the fact that Ant-Man would have to wait around for ages until Thanos goes to the bathroom because I swear the dude never takes a bathroom break in any of the movies or comics. If we consider the physical attributes of the characters, we can see that Thanos is significantly taller than Iron-Man.

Furthermore, Scott Lang, who is known as Ant-Man, is a little bit shorter than Tony Stark at his normal size. This means that if Ant-Man were to venture inside of Thanos's butthole, he wouldn't do much damage if he was standing upright at the same angle as the Titan. The body would severely hurt and would definitely result in the breaking of the bowels and misplacement of several different organs. However, given Thanos's immense power, he could likely overcome such injuries.

If Ant-Man were to regrow to his normal size, positioning himself sideways to target the lower regions and stomach of Thanos, the impact would be more severe. Coming out at an angle would definitely rip up more skin, but it's highly unlikely this would kill Thanos if he has the Infinity Gauntlet and can regenerate his body after seeing the damage.

No matter the angle or method, if Ant-Man regrew to this size, the end result would be a serious injury, but likely not fatal. The phrase 'No more Snappy Boi' encapsulates the irreparability of such actions.

Conclusion: While the idea is entertaining, it doesn't hold up to scientific scrutiny and relies on the comic book storytelling tradition of pushing the boundaries of reality for the sake of an exciting storyline.
