Stephen Hawking, one of the most brilliant scientists in modern history, warned before he died that Earth might one day become so badly damaged that people won’t be able to live here anymore.
He said this might happen by the year 2600, when the planet could turn into what he called a “giant fireball.” This wasn’t just a guess he based it on how quickly the human population is growing and how fast we are using up the planet’s natural resources like water, energy, and clean air.
Hawking explained that if we keep living the way we do now, the number of people on Earth will become too much for the planet to handle. He imagined a future where people would be packed so tightly together that they’d be standing shoulder to shoulder, with barely any space left.
He warned that this kind of overpopulation, along with pollution and climate change, could raise temperatures so much that Earth would become unlivable. That’s why he believed humans need to start making plans to live on other planets—because if we don’t, we might eventually go extinct.
NASA, the U.S. space agency, hasn’t said that Earth will become a fireball exactly like Hawking predicted, or that it will happen in the year 2600. But they do agree with him that the way we’re treating the planet is dangerous. They’ve said that if we keep using up resources the way we are now, without slowing down or changing our habits, we could face major problems even sooner.
NASA has been watching Earth from space for over 50 years, and they’ve seen clear signs that the planet is changing in ways that should worry us.
One example of these changes is happening in places where the ice is melting. Scientists recently found trees that had been frozen in ice for 6,000 years suddenly appearing again because the ice is melting too fast.
This shows that Earth’s temperature is rising in a way that’s not normal, and it’s happening faster than many people expected. These kinds of events back up what Hawking and NASA have been warning about: climate change is real, and it’s already affecting life on Earth.
Because of all these risks, Hawking believed we shouldn’t put all our hopes in saving Earth alone. He thought we should also be looking for other planets where people might be able to live someday. He supported a project called Breakthrough Starshot, which is working on building tiny space probes that could travel extremely fast and explore planets around other stars. These probes would help scientists find planets that might be safe for humans to move to in the future.
NASA is also working on space missions that could help us settle on other planets. They’ve been studying Mars and other places in the solar system to see if people could live there one day. At the same time, while we’re looking outward, we’re also still discovering new and surprising things right here on Earth like a rare species recently found in a Michigan forest that hadn’t been born there in over 100 years. This shows that Earth still has mysteries and beauty we need to protect, even as we plan for the future.
Hawking’s message was clear: if we don’t change our ways, Earth might not be a safe home forever. He believed we need to take better care of our planet right now, while also getting ready to explore and live on other planets just in case. NASA agrees, saying that time might be running out faster than we think. Together, their warnings remind us that the choices we make today will shape whether or not humanity survives far into the future.
