Yes, in about 1 billion years, the Sun's increasing brightness will cause Earth's oceans to evaporate, making the planet uninhabitable for complex life, though the Sun itself won't die for another 4 billion years; however, potential shorter-term threats like asteroid impacts or climate collapse could end humanity much sooner. While the Sun's eventual expansion into a red giant in 5 billion years will likely engulf Earth, the loss of habitability due to heat is the nearer, guaranteed threat, with some models suggesting even less than a billion years for humans.
Astronomers estimate that the sun has about 7 billion to 8 billion years left before it turns into a white dwarf. One way or another, humanity may well be long gone by then.
But how long can humans last? Eventually humans will go extinct. According to 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 1 sextillion years (10²¹ years), the universe will be a vastly different, dark place: the era of star formation will have ended, all stars will have burned out into white dwarfs, neutron stars, or black holes, planets will be cold and lifeless, and even protons might begin to decay, leading towards the "Big Freeze" or heat death, with only black holes slowly evaporating via Hawking radiation over unimaginable timescales. All familiar structures, including galaxies, will have long dissolved as the universe expands, leaving behind a cold, dark, and nearly empty expanse.
It still has about 5,000,000,000—five billion—years to go. When those five billion years are up, the Sun will become a red giant. That means the Sun will get bigger and cooler at the same time. When that happens, it will be different than the Sun we know today.
Yes, when you look at the Sun, you see it as it was about 8 minutes ago because light travels at a finite speed, taking roughly 8.3 minutes to cover the distance from the Sun to Earth, acting like a cosmic time machine, showing us the past of all celestial objects. This means if the Sun vanished, we wouldn't know for 8 minutes, and it also applies to everything else in space, with farther objects showing us even older history.
# 1: Coronal Mass Ejections
Yes, this can happen to humanity on Earth… it has happened before! The very source of life for humanity is, indeed, our greatest threat.
Humans Could Live For 1,000 Years by 2050—Ushering in the Dawn of 'Practical Immortality,' Futurists Say. Some experts warn that this radical change may remain out of reach for many, due to societal and economic challenges. Technology futurists foresee advances that will enable humans to live up to 1,000 years.
The Bible does not directly address the age of the Earth or the universe. The number of 6000 years came from Archbishop Ussher in the 17th century.
Finally, the planet will likely be absorbed 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.
The direct death toll alone could amount to tens to hundreds of millions of people. Or maybe even billions. If, in an absolute worst case scenario, 99 percent of the world population would die, that would leave 80 million people alive. Meaning in terms of population we would be back to 2500 BC.
The Triassic Period (252-201 million years ago) began after Earth's worst-ever extinction event devastated life. The Permian-Triassic extinction event, also known as the Great Dying, took place roughly 252 million years ago and was one of the most significant events in the history of our planet.
Kurzweil has forecast that by 2030, humans can accomplish what was previously considered impossible—biological immortality. The statement, though incredible, is not an imaginary one. Rather, it is underpinned by the rapid advancement of major scientific disciplines like nanotechnology, genetics, and robotics.
Planet-warming greenhouse gas emissions are expected to rise to 75 billion tonnes a year by 2050 – a nearly 50 per cent jump from today. This will destabilize the climate and lead to a surge in heatwaves, which are expected to affect nearly everyone on Earth – some 9.2 billion people – by 2050.
1 hour on Earth can equal 7 years in space (or vice versa) due to time dilation, a concept from Einstein's relativity where strong gravity or extreme speeds slow down time relative to an outside observer, famously depicted in the movie Interstellar on a planet near a black hole where an hour for the crew meant years passing on Earth. It's not about speed alone in orbit (ISS astronauts age slightly slower), but about proximity to immense mass, like a black hole, bending spacetime so drastically that time crawls for those nearby compared to time far away.
Clocks may have to skip a second — called a "negative leap second" — around 2029, a study in the journal Nature said Wednesday. "This is an unprecedented situation and a big deal," said study lead author Duncan Agnew, a geophysicist at the Scripps Institution of Oceanography at the University of California, San Diego.
The Jubilee of 2033
The year 2033 will be of exceptional significance for the Christian community and the entire world. This extraordinary year will mark the 2000th anniversary of the Redemption, an event that highlights the passion, death, and resurrection of Jesus Christ, the foundation of Christian faith.
Scripture does not mention the existence of dinosaurs—at least not as we now understand them—neither before nor after the Genesis Flood.
According to some Bible Scholars the Earth is a little over six thousand years old. There was two thousand years between Adam and Eve and the flood; two thousand years between the flood and the birth of Christ; and 2024 years between Christ and now at the present time.
8) New homes in 2050 will be highly energy-efficient – featuring several ways of capturing, storing, and distributing energy. 9) Due to climate change, homes will need to be more responsive to weather events. In addition, better cooling systems will ensure homes don't overheat in the potentially warmer summers.
In our absence, Earth would continue on. Our planet does not 'need' us. Life would last at least until our sun grows too hot to support it.
Most people expect to work to 65. That varies by generation, however: Gen Z expects to retire at age 60, Boomers at 72, Millennials at 64 and Gen X at 67. 32% of Millennials and 30% of Gen Z expect to live to 100 – higher than the 22% of Gen X and 21% of Boomers who expect to become a centenarian.
Some sources of catastrophic risk are anthropogenic (caused by humans), such as global warming, environmental degradation, and nuclear war. Others are non-anthropogenic or natural, such as meteor impacts or supervolcanoes.
On April 13, 2029, the large asteroid Apophis (99942) will have a very close, but safe flyby of Earth, passing within 32,000 kilometers (20,000 miles) of our planet—closer than some satellites—and will be visible to the naked eye in the night sky from parts of the Eastern Hemisphere (Europe, Africa, Asia) as a bright, fast-moving point of light. This rare event offers scientists a unique opportunity to study an asteroid of its size (about 375 meters wide) up close, with missions like NASA's OSIRIS-APEX and ESA's Ramses planned to observe it.
Return to the Moon
Artemis II, scheduled for launch between February and April sees the return of the first people to the Moon since Apollo 17 in 1972. Three American and one Canadian astronaut will orbit the Moon on a 10 day journey that lays the foundation for lunar landings in the coming years.
