"Trapped Intelligent Civilizations: A Cosmic Conundrum"

A new article in the Journal of the British Interplanetary Society introduces the concept of the Exoplanet Escape Factor and Fishbowl Worlds, which explore the ability of civilizations on other planets to explore their solar systems. The research suggests that civilizations on high-mass planets may be physically unable to escape their worlds, leading to the idea of inescapable "Fishbowl Worlds" where space travel is impractical. This raises questions about whether entire civilizations could rise and fall without ever knowing the Universe beyond their planet.
