Descoberta nova rota para Alpha Centauri

Reaching the stars is one of humanity's greatest dreams. Long before the first steps of space exploration, we were already observing the sky and trying to understand the universe. Since then, our missions have traveled far beyond Earth, but no probe has managed to reach another star. One of the main destinations for a future interstellar journey is Alpha Centauri, a A system composed of three stars, which is the closest to our solar system. Even so, the problem of distance ultimately proves relentless. Even the fastest probes we have today would still take thousands of years to reach Alpha Centauri. In today's video, we'll understand how an artificial intelligence managed to trace a route to this system. Hey everyone, before the video continues, let me give you one more update about our Stratospheric balloon video. Well, the edition is underway and it's turning out to be the most beautiful thing. Soon, I'll announce on my Instagram the release date of the video, which in fact It must come out in cinemas. Well, not in cinemas plural, but in the cinema, more specifically at Cine Cariri. located at Shopping Serrinha, in the city of Serrinha, Bahia. So, if you want the ticket and you live around here, please get in touch. Follow me on Instagram, where you can already reserve your ticket. It is a very symbolic value. Let's go to the video. Reaching the Sun has already become a reality, and today we study our incredible star from nearby However, reaching distant stars remains a dream of humanity. The distances are so great that even light, traveling at approximately 300,000 kilometers For a second, it takes years to cross them. Since the speeds of our conventional waves are quite limited, a journey to the The journey to the nearest stellar systems could take tens of thousands of years. This means that a mission launched today would continue traveling long after all of them the people involved in its construction having disappeared. One of the most interesting destinations turns out to be Alpha Centauri, the closest stellar system Alpha Centauri, consisting of three stars: Alpha Centauri A, B, and C. The first two orbit the common center of mass, completing one revolution in approximately 80 years old. The third one, known as Proxima Centauri, is a red dwarf, smaller and cooler, located a little closer to us. Well, the four-year gap may seem truly enormous to us, and it really is—we're talking about at least 39 trillion kilometers, but even so, traveling through space would take 70 million years playing bass. The system itself is very interesting, considering that the stars are quite similar to our own. For example, the reference star A has just 10% more mass than the Sun, and the Star B has 90% of the solar mass. The only one that's really different is Proxima Centauri, which is a red dwarf, much smaller that of ours Although they are not exact copies of the Sun, the two first stars offer an opportunity by closely studying stars relatively similar to the one that sustains life here on Earth. Considering the current distance of approximately 4.4 light-years to the primary pair, light takes slightly more than 4 years to travel this path. However, a spaceship could not simply reach that speed. According to the laws of relativity, accelerating an object with mass to the speed of light would require infinite energy Even reaching a significant fraction of this limit would already represent a technological leap. gigantic In addition to propulsion, it would be necessary to address impacts from interstellar particles, and maintain equipment operating for very long periods and transmitting information through trillions of kilometers. It was to explore a possible solution that the Breakthrough Starshot project emerged. The proposal involves sending tiny probes, propelled solely by the pressure of powerful sources laser beams that would be launched from here on Earth. The conceptual objective would be to reach approximately 20% of the speed of light, reducing the journey time to Alpha Centauri in about two decades. It's an impressive idea, but it depends on significant advancements and infrastructure. that still needs to be developed and demonstrated at the necessary scale. Now we have another alternative, the Fermi Explorer, which plans to launch a probe. to Alpha Centauri by 2029. The objective of the mission is much more realistic. Instead of reaching Alpha Centauri in a few decades, as planned by Breakthrough Starshot, They plan to reach there in 80,000 years. Of course, a long-standing mission. And for this, they developed an artificial intelligence-driven route that guides the probe on the way to the nearest stellar system. Let's understand. It is within this entire planning that Physical Super Intelligence, or PSI, a laboratory, appears. who uses artificial intelligence in physics research and participates in mission analyses. The company announced a fundraising of 58 million dollars to develop its operations. In this context, AI could develop and explore alternative trajectories, evaluating limitations and seek solutions compatible with the available resources. However, your participation does not mean that all challenges have been resolved. There already exists a route that has been conclusively proven to be superior to any other. The most curious detail is that the probe would need to aim at the future position of Alpha Centauri. Don't go in the direction she is heading now. The stars are constantly moving throughout the galaxy, and the planning takes this into account. closest approach at the time when the system crosses the plane of Earth's orbit in approximately 79,500 years, in an effort to reduce fuel and costs. By then, Alpha Centauri will be more than six light-years away from the Sun. Imagining this journey is thinking of a machine traversing space for millennia, carrying forward the initiative of people who will never know their destination, yet like intelligence Has artificial reached a solution? It all started when the researchers offered to analyze the issue with GetPhysicsDOM. an open-source software that breaks down complex physics problems into smaller tasks and organizes them necessary simulations The idea began to be developed using models such as Cloud and GPT. A trajectory was then created that met all the mission's requirements, leading taking into account the limitations of propulsion, energy, and costs. According to the team's account, a week later a proposal emerged from those in charge. the mission had not yet considered. Instead of immediately accelerating away from the Sun, the spacecraft would begin decelerating. closer to him, in a region of Mercury's orbit. During these approaches, the engine would be activated while the solar panels received a much brighter illumination. The strategy would also leverage the Oberti effect. The same change in velocity can produce a greater gain in orbital energy when applied at the moment when the ship is already moving faster. This combination would allow concentrating the engine's operation in the nearby passages. to the Sun, reducing the need for large solar panels and helping to keep the spacecraft stable level The system would have operated with considerable autonomy for three days, processing approximately a billion tokens, the units of information used in artificial intelligence models Nevertheless, there was human oversight. An astrophysicist from PSI supervised the analyses, requested cost estimates, and graphs. but clearer and also reviewed the result looking for errors. This is just the beginning of how artificial intelligence can assist in space missions. Who knows, in the future, with even more powerful models, a yet more accurate route and be produced quickly. In any case, the distances remain relentless, and conquering space and time It's very, very difficult.
