In recent weeks, Earth has experienced some of its shortest days on record, with the planet spinning fast enough to shave 1.4 milliseconds off its usual 24-hour day. While these natural accelerations in Earth’s spin may go unnoticed by most, the feeling that our world is spinning out of control metaphorically is a sentiment that many can relate to.
In the novel “Circular Motion,” the author explores the consequences of Earth spinning at an accelerated rate, imagining what would happen if the planet sped up by minutes, hours, or even 12 hours. The characters in the book find themselves increasingly overworked, struggling to keep up with the demands of everyday life as their days grow shorter. The high-speed global transport system in the book exacerbates the problem, creating a vicious cycle of rushing and productivity.
As Earth’s spin accelerates, it affects various aspects of life, from the flow of liquid metal in the planet’s interior to animal migration patterns and the appearance of the northern lights. The author had to selectively choose which effects to depict in the book, including the increase in cyclones due to the Coriolis effect, which creates fiercer storms as the planet spins faster.
One of the most compelling effects explored in the book is the impact of Earth’s spinning on gravity. As the planet rotates faster, the centrifugal force holding us to the ground weakens, causing us to feel lighter. The direction of gravity also becomes tilted, creating a sense of disorientation and imbalance as the characters navigate a world that is increasingly off-kilter.
Through the characters in “Circular Motion,” the author delves into themes of love, purpose, and belonging in a world that feels ungrounded and chaotic. Just as the characters seek meaning amidst the planet’s acceleration, readers are invited to reflect on their own sense of self and connection to the world around them.
Alex Foster’s “Circular Motion” offers a thought-provoking exploration of the consequences of a rapidly spinning Earth, inviting readers to ponder the implications of a world in flux. Join the New Scientist Book Club in delving into this captivating novel and exploring the profound questions it raises about our place in a changing world.
