In five billion years, the sun is expected to expand, becoming what is known as a red giant. “In this process of the sun becoming a red giant, it's likely going to obliterate the inner planets … likely Mercury and Venus will be destroyed,” Blackman said. Earth may survive the event, but will not be habitable.
For eons, Earth will continue to orbit the Sun. But, eventually, as the Sun cools and dims to a black dwarf, Earth's orbit will decay due to the emission of gravitational waves. Over a trillion trillion years, our once-blue planet will spiral into the dead Sun — a grand finale as the solar system goes dark forever.
Although some microorganisms living in the Earth's crust would survive, the majority of life would enjoy only a brief post-sun existence. Photosynthesis would halt immediately, and most plants would die in a few weeks.
So how long do we have until the Earth's biosphere dies? Remarkably, life on Earth only has a billion or so years left. There is some uncertainty in the calculations, but recent results suggest 1.5 billion years until the end.
Without the Sun , Earth's land, water, and air would all be frozen solid! Life on Earth would cease to exist. That's because almost all living things rely on the steady light and heat of the Sun. The Sun's heat makes liquid water on our planet possible.
With no sunlight, photosynthesis would stop, but that would only kill some of the plants—there are some larger trees that can survive for decades without it. Within a few days, however, the temperatures would begin to drop, and any humans left on the planet's surface would die soon after.
It is just far enough away to keep us from burning. And we get the amount of warmth needed for humans, animals and plants to live. If the sun would go out, no life could survive on most of earth's surface within a few weeks. Water and air would freeze over into sheets of ice.
Humans in the year 3000 will have a larger skull but, at the same time, a very small brain. "It's possible that we will develop thicker skulls, but if a scientific theory is to be believed, technology can also change the size of our brains," they write.
According to a US report, the sea level will increase by 2050. Due to which many cities and islands situated on the shores of the sea will get absorbed in the water. By 2050, 50% of jobs will also be lost because robots will be doing most of the work at that time. Let us tell you that 2050 will be a challenge to death.
In the next 1,000 years, the amount of languages spoken on the planet are set to seriously diminish, and all that extra heat and UV radiation could see darker skin become an evolutionary advantage. And we're all set to get a whole lot taller and thinner, if we want to survive, that is.
A boon for life
The gravitational pull of the moon moderates Earth's wobble, keeping the climate stable. That's a boon for life. Without it, we could have enormous climate mood swings over billions of years, with different areas getting extraordinarily hot and then plunging into long ice ages.
Without the moon, Earth might have a very different climate than it does today. This would have likely limited the movement of species around the world. Some plants and animals alive today might not even exist! If the moon were to disappear tonight, many more stars would be visible from Earth.
But we surface dwellers would feel the chill much sooner than that. Within a week, the average global surface temperature would drop below 0°F. In a year, it would dip to –100°.
Earth is at risk of catastrophic collapse 'as early as 2025 ... However a new study suggests a full or partial collapse is 'most likely' to happen this century and as early as 2025. It describes a general weakening of the current as it approaches a...
Eventually, the fuel of the sun - hydrogen - will run out. When this happens, the sun will begin to die. But don't worry, this should not happen for about 5 billion years. After the hydrogen runs out, there will be a period of 2-3 billion years whereby the sun will go through the phases of star death.
It is the pull of the Moon's gravity on the Earth that holds our planet in place. Without the Moon stabilising our tilt, it is possible that the Earth's tilt could vary wildly. It would move from no tilt (which means no seasons) to a large tilt (which means extreme weather and even ice ages).
The Social Security Administration's middle-range forecasts indicate that in 2050 e(0) will be 80.0 and 83.4 years for males and females, respectively (table 2). The Census Bureau (CB) forecasts that in 2050 e(0) for males and females will be 80.9 and 85.3 years, respectively.
The world population is expected to reach 8.5 billion people by 2030. India will overtake China as the most populated country on Earth. Nigeria will overtake the US as the third most populous country in the world. The fastest-growing demographic will be the elderly: 65+ people will hit one billion by 2030.
“By the 2070s, changes in global climate will likely include strong warming across the globe, up to 3 degrees Celsius (5.4 degrees Fahrenheit) relative to late 20th century climate,” said Alan Hamlet, associate professor in the Department of Civil and Environmental Engineering and Earth Sciences.
"Someone could even live to 1,000, but the probability of that is one in 1 quintillion," Milholland added. (If all the humans who have ever lived in the history of the species were totaled up, we'd still fall short of 1 quintillion.)
🦅 Humans evolving to fly is incredibly unlikely due to our existing physical makeup and the lack of evolutionary benefit. 🐒 Humans are part of the simians, a larger group of primates that includes monkeys, lemurs, and apes.
In 100 years, the world's population will probably be around 10 – 12 billion people, the rainforests will be largely cleared and the world would not be or look peaceful. We would have a shortage of resources such as water, food and habitation which would lead to conflicts and wars.
Far outside our solar system and out past the distant reaches of our galaxy—in the vast nothingness of space—the distance between gas and dust particles grows, limiting their ability to transfer heat. Temperatures in these vacuous regions can plummet to about -455 degrees Fahrenheit (2.7 kelvin). Are you shivering yet?
If the Sun randomly exploded today or tomorrow, humanity wouldn't survive. However, if the explosion isn't powerful enough and we would know in advance that it will happen, we might have a chance to prolong our existence for a couple of years.
