What If We Traveled One Billion Years Into the Past?

Imagine if you could cover all of human history in the blink of an eye, from the first steps out of the slime to the first steps on the moon, that's exactly where we are in cosmic terms, but in that short period of time we've done quite a bit. What would you see if you

traveled

a

billion

years

in the past? Has the Earth ever looked like a giant slush ball? How far would you have to go back to see the first humans? Are we already going extinct? This is

what

would happen if you

traveled

a

billion

years

into the past.

In a sense, we are all time travelers. We travel into the future at the rate of one second per second, but if you want to go back in time, you'll have to. faster than the speed of light, according to Einstein, or perhaps your time machine would jump through wormholes, a hypothetical tunnel that connects two different points in space-time, however you decide to travel through the mess of time, you will see the effects and then the Causes of the most powerful forces that shaped our world. You might wonder how many times the Earth froze while you watch the story unfold or

what

ever.

You will be surprised at the toll humanity has taken on this planet in such a short time. If you start in 2021 and go back, you would see the sixth mass extinction event happening right now, known as the Holocene extinction. We are currently experiencing one of the most destructive periods of our time caused by human activity as humans destroy coral reefs and rainforests. The numerous wildlife and plants that depend on these ecosystems die with them, according to the International Union for Conservation of Nature. 67 endangered species could become extinct in 100 years and since most of these extinctions are not documented, we will not even know what they are.

We know I've lost until it's gone, maybe not even then you'll visit the 18th and 19th centuries and be able to see the pollution created by the industrial revolution reversed into smokestacks, cities will shrink and return to their roots as rural farmland, while This will allow you to see. the explosion of the human race in terms of population and pollution if you want to retrace our first steps you will have to go back further, travel the planet 200,000 years ago and witness the arrival of our species, homo sapiens, go back seven years. millions of years to northern Chad and the oldest known human species could walk past you, known as cylanthropus jedensis, this mysterious link in our chain looked like an ape, but was the first to walk upright.

He seems friendly enough if you think you're challenged now. Imagine that living during this time you would need the skills these early humans learned to survive and you would need them quickly, but if you sign up for the great courses, you can also make this year your own by learning with a purpose and with the best . Experts in their fields delving into a wide range of topics, there is something for everyone. If you spend time with our early ancestors, you may want to take the Outdoor Fundamentals course that covers everything from grooming to navigation or perhaps an introduction to paleontology to prepare yourself mentally.

You can meet Spinosaurus, the largest carnivore that has ever walked the earth. You can watch or listen to these lectures on any device anywhere with the great courses and app, visit thegreatcoursesplus.com. What if you got a 14-day trial with unlimited access? That is the great opportunity. courses more dot com slash what if you don't have the opportunity to go back in time to get this deal and if you don't study you may not make it past the Jurassic era, but you travel back to 60 million years ago and you will see the first primates emerge from the humid jungles of Asia.

Well, go back to 65 million years ago and you would find yourself under the giant asteroid that created a global extinction event, the impact causing a tsunami and filling the air with dust and debris. The accident also caused massive volcanic eruptions around the world, with the sun obscured and the land flooded, the last of the dinosaurs became extinct, but without this event, mammals like us may never have taken over the planet. Go back 130 million years and you will see. The first flowers bloom as you travel 200 million years back in time. You will witness the disintegration of Pangea.

The landmass that will become continents as the earth breaks up. The lava eruptions will be so massive that they will kill almost 80 percent of species. On Earth, okay, go back another 20 million years and watch the first small, nocturnal mammals crawling in the dark and if you go back to 230 million years ago, you could see the first dinosaurs walking on two legs for the first time before of that. can happen, although the earth has to go through what would be known as the great extinction, also called the Permian extinction, 95 of all the species on earth died, but you could also see how the earth's landmasses come together to form Pangea.

Now you can take a walk from Argentina to China, but things get interesting about 375 million years ago, you would observe marine animals walking towards land for the first time, maybe you would see a titalic that looks like a salamander mixed with a fish, this strange creature would later evolve into mammals and amphibians, but like all the species you saw before, this growth does not occur without a cost and we are now in the first extinction event. Extinction by mineral splitting occurs when ice sheets extend from the polar caps into the oceans. Nearly 70 percent of all marine life died. it went out during this planetary freeze more than 460 million years ago.

Okay, keep going back and you can see how life began under water called the Cambrian explosion. The lineage of most species on our planet today can be traced back to this milestone, but scientists are still unsure how this unique event occurred between 635 and 850 million years ago. The Earth froze twice, once for almost 60 million years and the next time for 15 million years. One theory suggests that the Earth was only covered by a thin film of ice that allowed the Sun's rays to filter through and plant the seeds of life beneath, but go back a billion years in history and you'll be surprised to find that it doesn't. many during this time the red algae are forming spores to reproduce the cells are coming together to form larger organisms life on Earth is microscopic and not very threatening, but nothing has been more cruel to our planet in such a short time than humans, but maybe humans will fix things eventually, there could be a change in our planet or in our hearts that could set our future. on a different path or maybe like the dinosaurs and neanderthals we would simply be replaced by something else, so let's take our time machine and find out what would happen if we traveled a billion years into the future, well that's a story for another, and if
