  • within the vastness of the universe.

  • Humanity is not that big of a deal.

  • We're not here because we're meant to be here were just here.

  • If mathematical predictions are correct, we might only have 760 years left.

  • What would be the cause of our extinction?

  • What would we do if we knew exactly when our existence would come to an end?

  • And could we delay the inevitable?

  • This is what if?

  • And here's what would happen if we knew the exact time when humanity goes extinct.

  • 1993 in 1993.

  • Knowing that humanity's time on the planet is limited, astrophysicists J.

  • Richard got made a very daring prediction using nothing but statistics.

  • Basically, he calculated that there's a 50% chance that the end of human life will come sometime before the year 27 79.

  • That gives us 760 years to make our final arrangements and possibly past the Earth on to a new life form, or even leave the planet to itself altogether.

  • Stick around and we'll take you on a journey to the future of humanity.

  • 2029.

  • Nice night for Caleb.

  • Oh, approaching Paris calculating.

  • On April 13th 2029 the near earth asteroid named Apophis will pass within 31,000 kilometers of our planet.

  • That's 10 times closer to Earth than the moon is hand even closer than some satellites in orbit.

  • But this 370 meter wide asteroid won't hit the earth.

  • Instead, it will sweep by safely and continue its path around the sun.

  • 2030.

  • Reproductive technology would allow parents to preview and pick the genetic traits of their future babies.

  • The global population would grow to about 8.5 1,000,000,000 reached a crisis point.

  • The world's ecosystems would change faster than we've ever seen before.

  • Due to increased levels of CO.

  • Two up in the Earth's orbit.

  • Everything from spent rocket stages to debris from accidental collisions would create a wall of space junk.

  • It would be problematic for any spacecraft to leave the earth.

  • We'd have to find ways to clean up the upper atmosphere if we didn't want to be trapped on Earth forever.

  • If humanity managed to solve the space junk problem, we'd start establishing the first lunar bases, and that would mark the beginning of the permanent human presence outside of Earth 2045 on Earth, the global average temperature would rise by 1.5 degrees, surpassing the safe limit.

  • Even though humanity completely switched to clean energy sources, global warming would become catastrophic and hard to control due to warmer global temperatures.

  • The Great Barrier Reef would lose up to 90% of its corals.

  • The Amazon rainforest would largely be destroyed by wildfires, deforestation even after decades of conservation efforts, at least one million species in the wild would begin to go extinct.

  • This would be the beginning of the next mass extinction event on the Earth's history, although this time it would be caused by humans 2056 the Earth's population would grow to 10 billion people.

  • The earth would become the hottest it's been in the past three million years.

  • Extreme weather would rampant around the world.

  • Africa, the Middle East and Southeast Asia would be most affected by floods, hurricanes and droughts.

  • Parts of the planet would become uninhabitable, leaving 140 million people no other choice but to seek refuge someplace else.

  • 20 biotechnology implants would become available to the general public, resulting in humans merging with their technology on a biological level, never failing artificial organs, synthetic blood and nano scale brain interface is would become a new reality.

  • 2099 sea levels would rise upwards of six meters, forcing hundreds of millions of people to leave their homes.

  • Large scale evacuations and resettlement programs would be needed along the coastlines, costing humanity trillions of dollars in the process.

  • Because of the declining fertility rate and the significant number of casualties from environmental conditions, Earth's population would stabilize at 11 billion people 21 eighties humanity would start expanding into the solar system.

  • Mining asteroids and terra forming Mars would be under way.

  • More people would have access to space technology and a new form of terrorism would emerge.

  • It would be possible to hijack a spacecraft and use it to redirect asteroids towards the earth, the moon and Mars.

  • The lack of space infrastructure would leave space colonies particularly vulnerable.

  • 22 spaceships powered by antimatter propulsion would take humanity outside the solar system.

  • Automated unmanned probes would be sent to the far regions of the galaxy researching thousands of interstellar worlds.

  • By the end of the 23rd century, humans would have confirmation of a microbial alien life existing on a warm, wet, exo planet.

  • Within 100 light years of our solar system, 2300 decades of nanotechnology research and advancement would result in transforming the general public into trans humans or cyborgs.

  • Trans humans would have improved intelligence and strength among many superhero traits.

  • They would be able to sprint at very high speeds, become invisible or even transform their appearances at will.

  • 2500 humanity would level up from a type zero toe, a type one civilization on the Kardashian off scale.

  • That means humans would be able to harvest all of the Earth's energy and use it to power up their entire civilization.

  • They would already be able to control the weather and global climate, alter the course of earthquakes and build cities at the bottom of the ocean.

  • Next step would be developing ways to fully manipulate the sun's energy.

  • They might start building space mega structures like a Dyson sphere or even attempt to feed some of the sun's mass into a black hole, 27 79.

  • The chain of the previous events could lead to humanity completely disappearing from the earth, one way or another, we might end up moving to space colonies we had established.

  • Or it may not even be us anymore, but a new bio, technologically engineered species.

  • Of course, this is a rough timeline estimated by futurists, based on statistics in mathematical models.

  • If you're upset about humanity's coming extinction, remember that it only has a 50% chance of coming.

  • True, scientists calculated our date of extinction, using the same formula that marketers use to predict what products you might click on online or who you're going to vote for.

  • It's about probabilities, not guarantees.

  • Besides, other predictions tell us that we would face extinction not 760 but 10,000 years from now.

  • In that case, we'd be around long enough to see the Earth's Poles reverse around the year 3500 and computers reaching their ultimate potential sometime after the year 4000.

  • But how would knowing all this in advance change the way we live our lives?

  • Well, if we knew the date of our extinction with 100% accuracy, we could stop carrying a boater environment, hand our bodies.

  • We might focus on all the bad habits that only bring us short term happiness.

  • Our society could become more violent, more self harming, more inclined to start wars.

  • Or we could team up and try to get off this rock.

  • We could start looking for other places to move to beyond what our own solar system has to offer.

  • We could establish colonies with stable human populations.

  • Then, even in the event of Earth getting wiped out by some cosmic power, humans would continue to exist that could carry on until the universe itself collapsed and stopped existing.

  • But that's a story for another.

  • What if?

  • Hey, thanks for sticking around and making it to the end of this video.

  • You know you can help us to produce more of these long episodes by visiting our store and buying a shirt or hat.

  • Hoody.

  • The leggings are cool, and we sell this pet with self conscious A.
