Imagining the end of the world is something we’ve done throughout history. Stories of the apocalypse appear in cultures everywhere, often depicting a time when Earth will no longer be the same. Recently, tech mogul Elon Musk brought attention to the eventual fate of our planet, suggesting we might need to colonize Mars as the Sun will eventually incinerate Earth. Surprisingly, scientists recently discovered an Earth-like planet that survived after its star died out, hinting at the distant survival of our world.
The scientific community agrees on one thing: Earth’s future isn’t bright. The Sun is slowly getting hotter, which will eventually lead to the planet’s demise in about two billion years. In about five to six billion years, the Sun will expand into a red giant, and it’s uncertain whether Earth will be swallowed or just scorched.
Melinda Soares-Furtado, a physics professor at the University of Wisconsin-Madison, highlights the difficulty in predicting Earth’s exact fate due to the uncertainty in the Sun’s engulfment radius. The potential outcomes can sometimes feel like a grim mystery, leaving us all to wonder: will Earth meet its end with a bang or a whimper?
Cultural perspectives on this fate can be quite varied. Tim Burbery, an English professor and expert in geomythology, notes that not all ancient cultures imagined an end to Earth. Aristotle, for example, believed the universe was eternal, a view that remained influential until the Big Bang theory emerged. Helen Van Noorden, a classics professor at Cambridge University, mentions that ancient philosophies often didn’t foresee the world’s end. Instead, they featured cataclysmic events woven into their myths.
For instance, Zoroastrian tales depict the Sun standing still for ten days during an apocalypse, while the Talmud suggests Earth will cease to exist for a millennium after 6,000 years. Meanwhile, Christianity envisions a fiery end with references to a “new Earth” and cosmic destruction.
Despite their differences, many stories across cultures share themes of rebirth. After significant destruction, a new beginning often follows. Modern science echoes this idea: as the Sun burns away, materials from our solar system could contribute to the formation of new planets. Soares-Furtado points out that as the Sun expands, other moons may enter the habitability zone, possibly supporting new forms of life.
Ricardo Yarza, a graduate student studying astronomy, observes that our understanding of the universe has shifted. Today, we recognize that Earth is not the center of everything—instead, we are part of a vast and ever-changing cosmos. Understanding this can make human life feel temporary but also miraculous.
While many may ponder the fate of Earth with trepidation, the discussion allows us to explore our existence and its significance. The end of Earth will not just be a final judgment but possibly a transition, where what was once part of our world becomes the foundation for something new.
In the end, whether we hope for a serene ending or a dramatic finish, our quest to understand Earth’s fate reflects our deepest questions about life, loss, and renewal. With every thought about the future, we are reminded to appreciate the time we have right now.
