By that point, all life on the Earth will be extinct. The most probable fate of the planet is absorption by the Sun in about 7.5 billion years , after the star has entered the red giant phase and expanded beyond the planet’s current orbit.
How much longer will there be life on Earth?
End of the Sun
Gamma-ray burst or not, in about a billion years , most life on Earth will eventually die anyway due to a lack of oxygen. That’s according to a different study published in March in the journal Nature Geoscience.
What will happen to Earth in 5 billion years?
In roughly 5 billion years, the sun will run out of energy and drastically alter the solar system . Oceans will be baked dry. Entire planets will be consumed. ... Its outer layers will expand until they engulf much of the solar system, as it becomes what astronomers call a red giant.
What will Earth be like in 2025?
The continued destruction of the earth’s forest mantle as a result of human activities is another desperate concern. By 2025, some 3 billion people will live in land-short countries and another 2 billion will be living in urban areas with high levels of air pollution.
What will happen in 100 trillion years?
And so, in about 100 trillion years from now, every star in the Universe, large and small, will be a black dwarf . An inert chunk of matter with the mass of a star, but at the background temperature of the Universe. So now we have a Universe with no stars, only cold black dwarfs. ... The Universe will be completely dark.
Will the universe end?
Astronomers once thought the universe could collapse in a Big Crunch. Now most agree it will end with a Big Freeze . ... Trillions of years in the future, long after Earth is destroyed, the universe will drift apart until galaxy and star formation ceases.
What will happen after 1 million years?
In the year 1 million, Earth’s continents will look roughly the same as they do now and the sun will still shine as it does today. But humans could be so radically different that people today wouldn’t even recognize them, according to a new series from National Geographic.
How long before our sun dies?
The Sun is about 4.6 billion years old – gauged on the age of other objects in the Solar System that formed around the same time. Based on observations of other stars, astronomers predict it will reach the end of its life in about another 10 billion years .
How long have humans existed?
Approximately 300,000 years ago , the first Homo sapiens — anatomically modern humans — arose alongside our other hominid relatives.
What will be life like in 2050?
Seven billion people will live in urban areas by 2050; vastly outnumbering rural people. There will be more senior citizens than young people (between the ages of 12 and 17) and children (people under the age of 12).
What will happen if the Earth stops rotating?
At the Equator, the earth’s rotational motion is at its fastest, about a thousand miles an hour. If that motion suddenly stopped, the momentum would send things flying eastward . Moving rocks and oceans would trigger earthquakes and tsunamis. The still-moving atmosphere would scour landscapes.
What will happen when the sun dies?
After the Sun exhausts the hydrogen in its core, it will balloon into a red giant, consuming Venus and Mercury . Earth will become a scorched, lifeless rock — stripped of its atmosphere, its oceans boiled off. ... While the Sun won’t become a red giant for another 5 billion years, a lot can happen in that time.
Will a black hole come to earth?
Absolutely not . While a black hole does have an immense gravitational field, they are only “dangerous” if you get very close to them. ... It would get very dark of course and very cold, but the black hole’s gravity at our distance from it would not be a concern. Is there life on other planets?
What will happen at 2050?
By 2050, the global population is projected to rise to 9.7 billion , which is more than two billion more people to feed than today. When crops fail and starvation threatens, people are forced to fight or flee.
Where does space end?
Interplanetary space extends to the heliopause, whereupon the solar wind gives way to the winds of the interstellar medium. Interstellar space then continues to the edges of the galaxy, where it fades into the intergalactic void .
What happens when you reach the end of space?
Dark energy could still evolve , leading to a Universe that might either recollapse in a Big Crunch, expand forever, or speed up in its acceleration and eventually tear even the fabric of space apart in a catastrophic Big Rip. The different ways dark energy could evolve into the future.
