A giant radioactive creature stomping through coastal cities sounds like pure fiction. But what would actually happen if Godzilla were real? To mark the arrival of Apple TV+’s “Monarch: Legacy of Monsters” Season 2, a series that deepens the lore of the clandestine Monarch organisation and its Titan connections, Space.com posed that question to a group of working scientists. Their answers are more grounded than expected.
A Biome-Destroying Event
The physical consequences of a creature Godzilla’s size would be immediate and sweeping. “Godzilla’s presence would definitely be a biome-destroying event,” says Dr. Emily Zarka, monster scholar and host of “Monstrum.” “Due to the size of Godzilla and the other kaiju, there would be physical effects. I think that it would completely change life as we know it.”
Dr. Hans-Dieter Sues, senior research geologist and curator of vertebrate palaeontology at the Smithsonian Institution’s National Museum of Natural History, points to environmental damage as the core concern. “If Godzilla existed, its biggest impact would be the tremendous damage caused by its occasional excursions on land,” he says.
Sues notes that repeated land incursions would reshape plant life, favouring fast-recovering species like ferns. He also flags a more systemic risk tied to feeding behaviour. In some versions of the mythos, Godzilla consumes large quantities of marine animals, which Sues warns “could lead to a local or regional collapse of ocean food chains.”
Maritime Disruption, but Limited
The effects on shipping and ocean travel would be real, though more contained than disaster-movie logic might suggest. Dr. Deby Cassill, associate professor of Integrative Biology at the University of South Florida, puts it plainly: “Maritime disruptions would be real but localized.”
Cassill draws a practical comparison. “Whales already reshape shipping routes. We reroute vessels around their aggregations, spawning grounds, and seismic zones.” A radioactive signature, she argues, would actually make Godzilla trackable. “Assuming Godzilla has radioactive elements, we could trace that. It wouldn’t really be a question of collisions, unless he were in the shallower areas.”
She also points to what already lives undetected in the deep ocean, citing the 500-year-old Greenland shark as one example of large creatures thriving in near-total obscurity. By that logic, a deep-dwelling Godzilla might go largely unnoticed for long stretches.
Co-existence Is Not Impossible
The experts broadly agree that unprovoked, most damage would be incidental rather than targeted. The creature’s standard depiction has it subsisting on radiation, not hunting humans. Distance and depth would do much of the protective work.
- Land damage would be severe but geographically concentrated around incursion zones
- Radioactive traceability could enable early-warning rerouting for ships and coastal populations
- Deep-ocean behaviour would pose minimal direct threat to surface activity
- Ecosystem stress, particularly to marine food chains, represents the most durable long-term risk
The scenario requires setting aside the square-cube law, which makes a creature of Godzilla’s scale physically impossible in biological terms. But within the hypothetical, the scientific consensus leans toward disruption over extinction. Adaptation, not annihilation, is how humanity would most likely respond.
