Say the word "solar system" and our minds immediately picture it as home to many stellar families. Scientists view all of this with awe because they work so well together. But what if a planet threatened that peace? In fact, that planet is Neptune. Why is Neptune such a threat to our solar system?
Let's start with Neptune's distant relative, Jupiter, the largest planet in our solar system. What if the planet suddenly disappeared from our solar system? First, the orbits of other planets orbiting the sun will be slightly altered. Yes, but the most dangerous part is the millions of pieces of planetary debris that will eventually hit Earth and send us to the end of our lives. So if Neptune is in trouble, what about our solar system?
Neptune is a planet of 14 moons that is four times the size of Earth. In 1687, the English physicist and mathematician Isaac Newton published Principia Mathematica, a book that helped people understand how the planets move around the sun. Since then, scientists have discovered that the solar system is just a tiny star orbiting the center of the galaxy. This means that our solar system can sometimes pass in front of other stars, causing serious damage and eventually causing the planet to fall out of orbit.
Scientists believe that stellar flyby is a major event that must occur in the evolution of planetary systems. While scientists are still looking for signs that stellar flybys caused big changes in our solar system, given that most of those changes occurred 4.6 billion years ago, one might wonder, is there any evidence of stellar flybys in time?
The solar system is 4.6 billion years old, and its arrangement isn't stable, it's chaotic. If a planet is in a constant state of chaos, it cannot remain stable. In this case, the alignment of the planets would be disrupted by these disturbances, with disastrous consequences, since the entire solar system is held together by the gravitational forces between the stars.
Neptune is the most distant planet in the solar system at 4.47 billion kilometers from the Sun, which also makes it the most vulnerable. As we all know, our solar system is not a single planet, it is a system of asteroids, stars, meteoroids, gas, some of which cause damage to others, so they are all constantly on the move. So what does this mean for our ancient Neptune?
From a hypothetical point of view, Neptune would be the first planet to be swept by a star. Two scientists at the University of Toronto ran more than 3,000 simulations, all of which took place at different scales. The basis of the experiment is if a planet passes by. So they can estimate what's going to happen over the next few billion years. In fact, scientists in Canada have found that changing Neptune's orbit would require a distance of 0.03 AU, or 4.5 billion meters, to have any effect on the long-term stability of the solar system. Such a change in Neptune would make our solar system tenfold more unstable.
Scientists also suspect that if a nearby star happens to pass close to Neptune, it could change its orbit, with huge consequences for the rest of our solar system. You know what? The horror doesn't end there. If that's the case... The passing star, then, is not much of a hazard, which is normal for them, but disastrous for a planet. What's more, because of the distance between Neptune and Earth, we probably won't be able to see it until disaster strikes.
Scientists worry about how we can see a passing star, but unfortunately, figuring that out is a huge challenge. Astronomers have been struggling with the theory of gravity ever since Newton invented it. All of this comes down to the N-body problem, which illustrates how hard it is to predict gravitational interactions between a group of objects. It is mathematically impossible to solve this problem accurately, so astronomers have resorted to numerical approximations.
But here's the problem. The difficulty with numerical approximations is that planets move unpredictably, which means that small changes in the initial state of the system (even by a fraction of a billion) can have a big impact. Second, there is a big difference in time. Using digital solutions, scientists can estimate the number of models that will be unstable without losing their stability. However, solving the time scale problem is still difficult because the planets need to be simulated every day. Even with a modern computer, the simulation would take 3-4 weeks. All this leads us to the conclusion that Neptune is the only dangerous planet in our lives.
Two scientists at the California University of Technology proposed in January 2015 that Neptune follows a very long orbit around the sun, much farther out than Pluto. Most of their arguments come from mathematical models and computer simulations rather than observations. This is due to the apparent gravitational pull of the invisible planet on a strange set of small objects in orbit. According to this assumption, Neptune has ten times the mass of Earth, and its orbit is about twenty times farther from the Sun 39bet-kết quả bóng đá-kết quả xổ số miền bắc-kèo bóng đá -soi cầu bóng đá-đặt cược.
Dr. Whitmire, a retired professor of astrophysics at the University of Arkansas, claims that Planet 9 is responsible for comet storms on Earth and other planets. Dr Whitmire's research suggests that a comet is "expelled" by a large planet every 27 million years, causing mass extinctions. However, there is no evidence yet as to which comets are considered to pose a threat to Earth. There is hope, though, that the potential problems with near-Earth objects have been closely studied by observers. After simulations, scientists at the University of Toronto concluded that these stars will not pass through our solar system for another 100 billion years.
Although our beautiful planet continues to face many life crises, such as nuclear war, epidemics and extreme climate change. But that horror pales in comparison to what some scientists have predicted for our planet. In their vision, the end of the Earth would be destruction. In the most likely scenario, billions of years from now, the sun will expand and swallow the Earth. We may not be able to avoid a catastrophe.
An astronomer at Yale University, such as Gregory Laughlin, has studied the distant future and found it hard to believe that people's predictions of life are so rosy. Due to the development of technology, and the continuous development of our species, humans will survive for a certain amount of time after our solar system is extinct. But our ancestors had to make planet jumps. In order to settle in places beyond the solar system, it is very likely that future immigrants will forgo life on the stars and moon in favor of "way stations" in the universe.
In transit, we can use resources beyond the solar system. For example, ore collected from the asteroids and asteroids can be established in situ, artificial satellites and comets can simultaneously extract water, ice and volatile substances, solar energy can mirror the sun's radiation gathered in this place, to provide enough sunlight for the growth of plants, solar energy, nuclear reactors and reactors will provide all the energy needed. Because they're so close to Uranus and Neptune, there's a lot of hydrogen and helium.
By mixing organic materials such as asteroid rock material, organic compounds (methane) and nitrate fertilizers, a community of organisms that act as soil can be formed in the house. Water, ice and ammonia can be used to make oxygen and nitrogen and pumped into the air, where plants, shrubs, trees and animals can be added to form a whole renewable ecosystem. In such ecosystems, plants produce oxygen and remove carbon dioxide from the atmosphere, while land and vegetation create nitrogen and water cycles, just as we do here on Earth. The space station will also serve as a base to collect supplies for robotic or human transport vehicles. If there is a surplus of resources, such as diamonds, gold and platinum, then this material can be used as a special material for indoor and above-ground rotating houses. Over time, a strong economic civilization will emerge.
It is hard to imagine that bases outside our solar system are ideal places for all kinds of scientific research. But... Do you think we humans can save ourselves from disaster?
