Billions of years ago, Earth, along with the rest of our solar system, was entirely unrecognizable, existing only as an enormous cloud of dust and gas.
In about one billion years, the solar luminosity will be 10% higher, causing the atmosphere to become a "moist greenhouse", resulting in a runaway evaporation of the oceans. As a likely consequence, plate tectonics and the entire carbon cycle will end.
But no matter what, a cataclysmic event 1 billion years from now will likely rob the planet of oxygen, wiping out life. Life is resilient. The first living things on Earth appeared as far back as 4 billion years ago, according to some scientists.
At the cosmic origin, a trillion years ago, all that existed was an endless Light Ocean. Inexhaustible was this frozen supply of light available for black holes to continually build spheres and solar systems in galaxies.
The model, called Mindy, provides a terrifying glimpse at what people could look like in 800 years if our love of technology continues. According to the company, humans in the year 3000 could have a hunched back, wide neck, clawed hand from texting and a second set of eyelids.
Eventually humans will go extinct. At the most wildly optimistic estimate, our species will last perhaps another billion years but end when the expanding envelope of the sun swells outward and heats the planet to a Venus-like state. But a billion years is a long time.
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. Why?
The current expansion will continue forever, gaining speed, so that all the galaxies we now observe, 100 billion or so of them, will one day disappear beyond our ability to detect them. Our galaxy will be alone in the visible universe. And then, once the stars burn out, the universe will be truly cold, dark and empty.
The earliest life forms we know of were microscopic organisms (microbes) that left signals of their presence in rocks about 3.7 billion years old. The signals consisted of a type of carbon molecule that is produced by living things.
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.
So when plants die from the lack of carbon dioxide, it's not just a loss in the food chain but, crucially, a loss in the air they produce and the air we breathe. While the end of oxygen is still a billion years away, when the depletion begins to take hold, it will occur rather rapidly, in about 10,000 years.
There will be "far worse extreme weather events than those we see today. withering droughts, epic floods, deadly hurricanes, and almost inconceivably hot heatwaves; a typical summer day in midlatitude regions like the U.S. will resemble the hottest day we have thus far ever seen." Dr.
In the same context, when we proceed to a million years of evolution of mankind, we might become a hybrid of physiology and cybernetic prosthetics. In science fiction terms, we might become cyborgs, a more durable form. Modern humans might be able to transform a human being into something else.
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. We will need to figure out ways of how to accommodate 100+ people at work.
One billion years from now, Earth's atmosphere will contain very little oxygen, making it uninhabitable for complex aerobic life. Today, oxygen makes up around 21 per cent of Earth's atmosphere. Its oxygen-rich nature is ideal for large and complex organisms, like humans, that require the gas to survive.
The collision corresponds to the Big Crunch, then a Big Bang. The matter and radiation around us today are quantum fluctuations from before the branes. After several billion years, the universe has reached its modern state, and it will start contracting in another several billion years.
The largest stars will die and give way to neutron stars and black holes. Stars like our own sun will become white dwarfs. Red dwarfs will lose their ability to continue fusion, turning into black dwarfs—a strange kind of non-radiating stellar object that does not yet exist in our comparatively young universe.
The ultimate fate of an open universe is either universal heat death, a "Big Freeze" (not to be confused with heat death, despite seemingly similar name interpretation ; see §Theories about the end of the universe below), or a "Big Rip" – in particular dark energy, quintessence, and the Big Rip scenario – where the ...
Broadly speaking, evolution simply means the gradual change in the genetics of a population over time. From that standpoint, human beings are constantly evolving and will continue to do so long as we continue to successfully reproduce.
More reproduction followed, and more mistakes, the process repeating over billions of generations. Finally, Homo sapiens appeared. But we aren't the end of that story. Evolution won't stop with us, and we might even be evolving faster than ever.
While our ancestors have been around for about six million years, the modern form of humans only evolved about 200,000 years ago. Civilization as we know it is only about 6,000 years old, and industrialization started in the earnest only in the 1800s.
Human extinction is the hypothetical end of the human species due to either natural causes such as population decline from sub-replacement fertility, an asteroid impact, large-scale volcanism, or via anthropogenic destruction (self-extinction).
New genetic findings suggest that early humans living about one million years ago were extremely close to extinction. The genetic evidence suggests that the effective population—an indicator of genetic diversity—of early human species back then, including Homo erectus, H. ergaster and archaic H.
They would still probably be small, scrawny, and very generalized. But instead, the mammals were able to evolve and diversify and, well, ultimately, millions of years later, become some humans. So perhaps we would not have been here if it weren't for this extinction event 65 million years ago.
