Scientists came to this conclusion when they tried to simulate the slow movement of the continents over the next few tens of millions of years.
Scientists analyzed the magnetism of ancient rocks to calculate their position on Earth over time, and measured how the mantle under the earth's crust, will move the continents that float on its surface.
They figured out that a supercontinent called Amasia is about to form over the Arctic.
First, the two parts of America will connect, moving towards the north, which will lead to a collision with Europe and Asia at the North Pole. Australia will continue on its way north and nestle on India.
The idea of a supercontinent is not new. About 300 million years ago, the supercontinent Pangea included all 7 continents. But top part The Earth's mantle remains quite fluid, and as it shifts, so do the tectonic plates above it, which causes short-term earthquakes, moving entire continents over millions of years. So the movement of tectonic plates split Pangea about 200 million years ago, just as it split the previous supercontinent Rodinia 500 million years ago.

What will the Earth look like in 5000 years?
February 28, 2018Over the past five thousand years human civilization made significant progress in its technological development. The appearance of our planet today is a clear indicator of how much we are able to change the natural landscape.
people and energy
People have learned to influence not only the landscape, but also the climate and biodiversity of the planet. We have learned how to build giant skyscrapers for the living and huge pyramids for the dead. Perhaps the most important technological knowledge and skill that we have acquired in the process of developing science and culture is the ability to use the energy of the world around us: geothermal, solar, wind, and so on.
We can already extract energy from the atmosphere and the bowels of the Earth, but we need more and more all the time.
This inexhaustible appetite for more and more energy has always determined and continues to determine the development of global human civilization. It is he who will become the engine of development in the next five thousand years and dictate what life on planet Earth will look like in 7010 AD.
Kardashev scale
In 1964, Russian astrophysicist Nikolai Kardashev put forward a theory about the technological development of civilizations. According to his theory, the technological progress and development of a particular civilization is directly related to the total amount of energy subject to its representatives.
Taking into account the stated principles, Kardashev identified three classes of advanced galactic civilizations:
- Type I civilizations have learned to control all the total energy of their planet, including its interior, atmosphere and satellites.
- Type II civilizations have mastered the star system and mastered its total energy.
- Type III civilizations control energy on a galactic scale.
Cosmology often uses this so-called Kardashev scale to predict the technological progress of future and alien civilizations.
Type I civilization
Modern humans don't even appear on the scale yet. In fact, the global human civilization belongs to the zero type, that is, it is not advanced. Scientists are confident that in a relatively short time we will be able to achieve the status of a civilization of the first type. Kardashev himself predicted that this moment would come. But when?
Theoretical futurist physicist Michio Kaku predicts that the transition will occur within a century, while his colleague, physicist Freeman Dyson, suggests that it will take twice as long for humans to reach the status of an advanced civilization.
Kardashev, during a discussion of his theory, predicted that mankind would reach the status of a Type II civilization in 3,200 years.
If humanity can only reach the rank of Type I civilization in five thousand years, this will mean that we will be able to freely control atmospheric and geothermal forces and processes. This means that we can decide ecological problems, however, wars and self-destruction could still threaten the survival of humanity as a species even in 7020.
Type II civilization
If the planet Earth reaches Type II status in 5,000 years, then the people of the 71st century will have enormous technological power. Dyson suggested that such a civilization would be able to surround the star with satellites in order to use its energy. In addition, the technological achievements of such a civilization will most certainly include the possibility of interstellar travel, the creation of off-planet colonies and the movement of space objects, not to mention achievements in computer technology and genetics.
Humans in such a future are likely to be vastly different from us, not only culturally, but possibly genetically as well. Futurists and philosophers call the future representative of our civilization a posthuman or transhuman.
Despite these predictions, a lot can happen to our planet and to us in five thousand years. We could destroy humanity nuclear war or unwittingly ruin the planet. At the present level, we will not be able to cope with the threat of a collision with a meteorite or a comet. Theoretically, we could face alien civilization Type II long before we ourselves reach the same level.

drift theory. All continents are moving. Their movement is based on the theory of drift of lithospheric plates. Initially, the basis of theoretical geology of the early twentieth century was the contraction hypothesis. The earth cools like a baked apple, and wrinkles appear on it in the form of mountain ranges. This hypothesis was opposed by the German meteorologist Alfred Wegener with a report on the drift of the continents. But his theory was rejected because. could not find the force that moves huge continents. Alfred Lothar Wegener German geologist and meteorologist, creator of the theory of continental drift. He died in 1930 during the third expedition to Greenland, without proving his theory. Types of plate displacement. Collision of continents The collision of continental plates leads to the collapse of the crust and the formation of mountain ranges. This is an unstable structure, it is intensively destroyed by surface and tectonic erosion. Active continental margins. An active continental margin occurs where oceanic crust sinks under a continent. Island arcs. Island arcs are chains of volcanic islands above a subduction zone, occurring where an oceanic plate subducts under a second oceanic one. Ocean Rifts. On the oceanic crust, rifts are confined to the central parts of the mid-ocean ridges. They form a new oceanic crust. From the analysis of the movements of the continents, an empirical observation was made that every 400-600 million years the continents gather into a huge continent containing almost the entire continental crust - a supercontinent. Modern continents were formed 200-150 million years ago, as a result of the split of the supercontinent Pangea. Rodinia. Rodinia (from Russian Rodina) is a supercontinent that existed in the Proterozoic, a zone of the Precambrian period. It originated about 1 billion years ago and split up about 750 million years ago. Rodinia is often considered the oldest known supercontinent, but its position and shape is still a matter of controversy. Pangea. Pangea is the name given by Alfred Wegener to the procontinent that arose during the Mesozoic era. Pangea broke up about 150-220 million years ago. Laurasia and Gondwana. Pangea split into two continents. northern mainland Laurasia later split into Eurasia and North America, at the same time as from southern continent Gondwana later originated Africa, South America, India, Australia and Antarctica. Tectonics on other planets. There is currently no evidence of modern plate tectonics on other planets. solar system. Research magnetic field Mars, conducted in 1999 by the Mars Global Surveyor space station, indicate the possibility of plate tectonics on Mars in the past. Earth in 50 million years. It is assumed that in 50 million years the Indian and Atlantic Ocean s, Quiet will decrease in size. Africa will move north. Australia will cross the equator and come into contact with Eurasia. Earth in 100 million years. The Mediterranean will be cut in half. North and South America will change their direction and move to the east. The Atlantic Ocean will be divided into two parts "North Atlantic" and "South Atlantic". Antarctic snow will gradually begin to thaw. Earth in 250 million years. After 250 million years, Australia will be completely connected with Indochina, Indonesia will turn into a plateau or a high plateau. The Mediterranean will no longer exist. In its place, mountains will rise that can give shape to the current peaks of the Himalayas. The southern limb of Africa will be sandwiched between South America and Southeast Asia, and gradually, sinking, will turn into a large lake ...

On the scale of the history of the planet and even humanity, the life of one particular person is catastrophically small. We, who were born at the turn of the millennium, were lucky to witness unprecedented technological progress and the flourishing of civilization. But what will happen next? In 50, 10, 1000 years? In these documentaries eminent scientists and researchers will try to imagine what awaits humanity and our planet in the future.
Age of Fools
The film will paint us a picture of the near future (2055), when global warming is already destroying mankind. The protagonist the film should send a message to those people who might survive. The purpose of the message is to draw conclusions why all this happened.
From a Science Perspective: Earth Apocalypse
Imagine our planet in 250 million years. It will faintly resemble today's Earth, most likely it will be one large continent, mainly occupied by deserts. There will be no oceans in today's view. Coastal zones will be destroyed by crushing storms. Ultimately, the planet Earth is doomed to destruction.
Wild world of the future
Without a time machine, you will be transported into the future by 5,000,000, 100,000,000 and 200,000,000 years to see a world worthy of the pen of a brilliant science fiction writer. But what will appear to your eyes is not fiction at all! Using the most complex calculations, rigorously substantiated forecasts and the richest knowledge in biology and geology, leading scientists from the USA, Great Britain, Germany and Canada, together with masters of computer animation, created a portrait of our planet and its inhabitants many centuries after the last person leaves it.
World in 2050
Can you imagine our world in 2050? By the middle of the century, there will already be about 9 billion people on the planet, consuming more and more resources, surrounded by an increasingly technological space. What will our cities look like? How will we eat in the future? Is global warming coming, or will engineers be able to prevent a climate crisis? In that documentary BBC, deals with the problem of overpopulation of the earth. Certainly, in the future we expect demographic problems. Rockefeller Institute theoretical biologist Joel Coen suggests that it is likely that most people in the world will live in urban areas and their average life expectancy will be substantially higher.
New world - Future life on earth
Programs from the series " New world» tell us about the latest technologies, developments, radical ideas that are already shaping the world of the future today. What will life on our planet look like in a few decades? Will there really be cities under the ocean, bio-suits and space tourism; machines will be able to develop super-speed, and human life expectancy will reach 150 years? Scientists say our descendants will live in floating cities, fly to work and travel underwater. The time of polluted megacities will end, because people will stop driving cars, and the invention of the teleport will save cities from eternal traffic jams.
Earth 2100
The very idea that within the next century, life as we know it may end will seem very strange to many. Our civilization may collapse, leaving only traces of human existence. To change your future, you must first imagine it. It seems outlandish, extraordinary and even impossible. But according to ultramodern scientific research it's a very real possibility. And if we continue to live the way we live now, all this will definitely happen.
Life after people
This film is based on the results of the study of territories suddenly abandoned by people, as well as possible consequences cessation of maintenance of buildings and urban infrastructure. The abandoned world hypothesis is illustrated with digital images showing the subsequent fate of such architectural masterpieces as the Empire State Building, Buckingham Palace, the Sears Tower, the Space Needle, the Golden Gate Bridge and the Eiffel Tower.
From the point of view of science: the death of the Earth
Planet Earth: 4 billion years of evolution, all this will disappear. Titanic forces are already at work that will destroy the world as we know it. Together with scientific researchers, we will make a grand journey into the future of the Earth in which natural disasters wipe out all life and destroy the planet itself. We're starting the countdown to the end of the world.
A year ago, in a speech at the Oxford University Union, the legendary Stephen Hawking declared that humanity could only survive for another 1,000 years. We have compiled the most exciting predictions for the new millennium.

1. People will live for 1000 years.
Millionaires are already investing millions of dollars in research to slow or stop aging entirely. In 1000 years, medical engineers may be able to develop remedies for every ingredient that causes tissue to age. The gene-editing tools are already here, which could potentially control our genes and make humans immune to disease.
2. People will move to another planet. In 1000 years, the only way for mankind to survive may be to create new settlements in space. SpaceX has a mission to "allow humans to become a space civilization." Company founder Elon Musk hopes for the first launch of his spaceship by 2022, which will head towards Mars.
3. We will all look the same. In my speculative mental experiment dr Kwan suggested that in the far future (100,000 years from now), humans will develop larger foreheads, larger nostrils, larger eyes, and more pigmented skin. Scientists are already working on ways to edit genomes so that parents can choose what their children will look like.
4. There will be super-fast smart computers. In 2014, a supercomputer performed the most accurate simulation of the human brain to date. In 1000 years, computers will predict coincidences and overtake the computational speed of the human brain.
5. People will become cyborgs. Machines can already improve human hearing and vision. Scientists and engineers are developing bionic eyes to help blind people see. In 1000 years, merging with technology may be the only way for humanity to compete with artificial intelligence.
6. Mass extinction. The last mass extinction wiped out the dinosaurs. A recent study found that the extinction rate for species in the 20th century was up to 100 times higher than it would normally be without human impact. According to some scientists, only a gradual decline in population can help civilization survive.
7. We will all speak the same language global language. The main factor most likely to lead to a universal language is the ordering of languages. Linguists predict that 90% of languages will disappear in 100 years due to migration, and the rest will become simplified.
8. Nanotechnology will solve the energy and pollution crisis. In 1000 years, nanotechnology will be able to eliminate environmental damage, purify water and air, and harness the energy of the sun.
