"We Might Have 100 Years Left!" Neil deGrasse Tyson On The World Ending

Well-known astrophysicist Neil deGrasse Tyson isn't new to wrestling with some of the universe's biggest and most confounding questions. He has spent a career under the stars, explaining the cosmos, and providing a grounded scientific perspective on everything from black holes to the future of humanity. And yet, when Tyson speaks about the possibility that the world might end within 100 years, that's enough to make even the most optimistic of us pause.

Not Sensation but Stark Warning

This is not a product of superstition or apocalyptic prophecy, but rather, the basis for predicting that humanity might just have 100 years more lies in his thorough knowledge of dangers both from our own deeds and those that the cosmos may spring at us. His message is very explicit: in order for humanity to continue surviving, it needs to know how best to manage its technology, resources, and collective willpower against both natural and human-made catastrophes.

The Earth has been around for billions of years," Tyson says often. "It's not the planet that's in jeopardy; it's us."

The Two Pronged Threat: Nature and Us

One of the most profound threats Tyson makes is from the two-pronged threat: cosmic and terrestrial. On the one hand, the Earth sits vulnerably before all these random cosmic events: asteroid strike, gamma-ray burst, or supervolcanic eruption. Such are natural phenomena for which humankind has some control over. An asteroid, for instance, wiped out the dinosaurs millions of years ago, and Tyson frequently reminds us that such an event could happen again. With no concrete way to deflect such a threat at the moment, the question is not if, but when.

On the other hand, dangers we have created for ourselves-including climate change, the possibility of nuclear war, and the misuse of artificial intelligence-present a challenge that is largely in our control but increasingly difficult to manage. In short, we have used science and technology to provide us with fantastic achievements but also to give us the instruments of our own destruction.

"If we don't get smarter about how we handle our environment and how we wield our technological power, we're not going to last much longer," Tyson warns.

The Climate Crisis

Among the most pressing and existential dangers facing humanity, according to Tyson, is the climate crisis. Snow and ice melt away due to rising temperatures; extreme, unprecedented weather causes destruction; and sea levels rise-and rising, suggesting that humanity has reached the Earth's limits of ecological accommodation to alarming degrees. It seems that the scientific consensus regarding climate change is overwhelming, and current effects are already being felt all over the globe. Unless we dramatically alter our behaviour, the next century might be one of catastrophic damage to the environment, and parts of the planet may become uninhabitable.

"We're the first species in a position to hasten our own extinction and we're doing it quite well," he jokes, but what his humor hides is the seriousness of the message in the discussion.

Nuclear and Technological Risks

The second ticking time bomb Tyson talks about is the proliferation of nuclear weapons. Since the discovery of the nuclear bomb, the power of nuclear arms has become the looming shadow behind human peace. It has such widespread potential for global devastation if there is a nuclear war, and its risk grows with more countries developing advanced arsenals.

More than this, the fast rise of artificial intelligence brings with it in its own classes of dangers. Tyson "acknowledges the promise of AI but warns against the 'unchecked development of technology without careful ethical considerations'. Without good stewardship, AI can spin out of control whether through unintended consequences or to the wrong people.

The Silver Lining: A Call for Action

But dire warning as the message from Tyson isn't defeatism. He believes that humanity is capable of changing its course. In most words, humans are "incredibly resilient and resourceful." That ingenuity that took us to the Moon and decoded the mysteries of the universe could be used to ensure we won't destroy ourselves.

He asks the world for some kind of cooperation, scientific literacy, and a deep sense of stewardship over our earth. He calls mankind to put together the very long-term sustainability over short-term gain, to invest in sciences, and to learn that life on Earth is all interconnected.

"We can either ride this wave of technological progress into a brighter future, or we can crash spectacularly," Tyson notes. "It's up to us."

Conclusion: A Choice to Make

It is in the lines, "This is a stark warning about our future, not a harbinger of fear but a call to action." While calling us to realize the balance at which we are holding our planet and the cosmos, Neil deGrasse Tyson reminds us of both great responsibility and possibility in shaping our future.

The universe will keep going, regardless of us. But whether or not we're here to observe it depends on the choices we make today," at least according to Tyson.

So, if we continue down this path but don't do anything about it, then we're only going to last for 100 more years. On the other hand, we also have a possibility of creating an endless timeline that can change things for the better. But it all depends upon how we rise to meet challenges in our lifetime.
