• Elon Musk doomsday prediction timeline: Scientists confirmed what Musk predicts: that life on Earth will end in about 1.08 billion years due to rising heat and falling oxygen caused by the sun.
• The sun will expand into a red giant in five billion years and may destroy Earth completely, as Musk predicts.
• Musk urges colonizing Mars now to create a self-sustaining backup for humanity before it’s too late.

Elon Musk recently warned that the sun will one day destroy all life on Earth. Now, scientists say he’s right. A team from NASA and T?h? University in Japan used supercomputers to study the sun’s future. They created advanced models to simulate how the sun affects Earth over time. Their research shows that Earth will become uninhabitable in about 1.08 billion years, just as Musk predicts. The sun will slowly grow brighter and hotter. That will raise global temperatures and reduce oxygen levels. Humans, animals, and plants will die off. Only microbes that don’t need oxygen will survive.

Earth’s Climate Will Collapse Long Before the Sun Explodes

The sun still has around five billion years before it burns out. But life on Earth won’t make it that long. The climate will become unstable much earlier. Rising heat will destroy ecosystems. Oxygen levels will drop until breathing becomes impossible. Most living things will disappear, as Musk predicts. Plants that make oxygen will vanish. Animals will follow. The planet will turn into a dry, toxic place. Life will only survive deep underground or in oceans, where oxygen is less critical.

Scientists Ran Over 400,000 Climate Simulations

To get these results, researchers ran more than 400,000 simulations. They tested how the sun’s heat affects climate and air composition. The study, published in Nature Geoscience, gave them a clear timeline. Earth’s breathable air will last about 1.08 billion more years. After that, oxygen levels will fall below one percent of today’s atmosphere. Complex life cannot survive without oxygen. That’s when mass extinction begins, confirming what Musk predicts. Only anaerobic microbes, which live without oxygen, will be left.

The Sun Will Become a Red Giant and May Swallow Earth

Eventually, the sun will run out of hydrogen. It will swell into a red giant. This stage will happen in around five billion years. When that happens, it may swallow the inner planets. Mercury and Venus will almost certainly burn up. Earth might be pulled in too. Even if it survives, life will already be gone. The surface will be too hot and dry. Musk sees this future as a clear warning. He says it’s time to start planning for life elsewhere.

Elon Musk Calls Mars the Key to Humanity’s Future

Musk believes colonizing Mars is critical for survival. He calls Mars “life insurance” for the human race. On Fox News, Musk explained that Earth will one day be destroyed. He said humans need a second home. Mars must be able to grow and survive without help from Earth. If it relies on supplies from home, it will fail. He wants a self-sustaining colony that can go on even if Earth disappears. Musk says we must act before disaster strikes.

Musk Uses the “Fork in the Road” to Explain Big Decisions

Musk often talks about “forks in the road.” These are key moments that shape the future. He used this idea when he bought Twitter and when he pushed for Mars missions. He believes humanity now faces one of those moments. We can stay on Earth and risk everything. Or we can build a second home on Mars. He wants Mars to become strong enough to survive on its own. That would ensure life continues even if Earth does not.

Trump Helped Fund Space Missions by Cutting NASA Programs

Former President Donald Trump helped shift focus to Mars. In 2018, his administration cut $6 billion from NASA’s science programs. That money had supported the International Space Station and the Mars Sample Return mission. Instead, the funds were moved to manned space missions. Over $1 billion went into sending humans deeper into space. The White House said this would help America lead in space exploration. That move aligned with Musk’s plans for SpaceX and Mars.

NASA Now Focuses on Manned Missions to Mars and the Moon

With the new budget, NASA turned to the moon and Mars. Officials want to beat China back to the moon. After that, the next goal is putting people on Mars. This fits perfectly with what Musk wants. SpaceX already makes rockets for deep space travel. Musk says the first human trip to Mars could happen in the next few decades. But building a self-sustaining colony will take much longer. That’s why he says we must start now, while Earth still supports life.
