Aboard the Venus-Valkyrie prepare to discover the earliest Supernovas and how they formed the building blocks of life, in particular those that would come to form our home solar system, The Milky Way.

The ship comes out of hyperspace, the flashing lights and colors dissipate from around the hull. From the galaxies that you saw forming when we left the young universe previously; you begin to see just how many stars have come to life, the universe is full of these infant galaxies and stars. Over thousands of years have passed, we have traversed time and space to see the universe at it’s earliest point where the building blocks for life as we know it, are forming.

The production process of forming elements, shut down after the heaviest element at the time, Iron was created. This resulted in the young universe you see ahead of you supplied with many of the building blocks for life as we know it, today, though it’s still not quite complete. What we have in this young universe is all the building blocks required to form water, H2O, there were even a few of the elements we need in order to create a human. There were some metals missing, such as zinc, humans cannot survive without this. The universe was about to leap to life again, forming yet more, even heavier elements than Iron.

In order for these elements to be created, there would need to be a huge amount of energy released, this means some huge, incredibly huge even, explosions that the universe has ever seen.

Huge galactic explosions – Supernovas

The point of time in which he have come back to the young universe, sees the universe at about 500 million years old, yet, another 13 billion years will pass before humans emerge in this universe. For those evolution points to occur, heavy metals such as Chromium and Zinc, need to be formed as well as Gold and Platinum.

The universe has a way to bring these elements in to being, via the massive explosions that were mentioned before. It was giant new stars that formed the previous elements including Iron, the universe has conjured a up a way for even heavier elements to be formed. Huge stars exploding which will come to be known as Supernovas. When the giant stars had depleted their energy forming the previous building blocks, they would collapse in on themselves, causing huge explosions, fusing elements even heavier than iron, thus restarting the element production line again.

Life as we know it would not exist without core collapse supernova events, one of the recent biggest supernovas provided scientists the opportunity to learn exactly what elements were being formed from within the explosion.

When the particles collide, they create enormous energy fusing, more of these particles add to this fusion, allowing for elements all the way up to the top of the periodic table to be created. As massive stars evolve, they have an iron core, with layers of successively lighter elements on the outside; inside the core, the temperature rises to around eight billion degrees, nearly 300 times hotter than the centre of the sun.

A Supernova – The result of a giant star collapsing.

It’s so hot that the iron core is ripped apart, this causes the start to become unstable, once unstable it begins to collapse from within. Within a fraction of a second, the core collapses at speeds of more than forty-three thousand miles per second. Lexi turns to you and says, ‘that means, a volume the size of planet Earth, crunches down to 8 times the size of Manhattan in an instant.’

This core then becomes super dense, one cubic square of that matter would be around the size of a sugar cube. Despite it’s incredibly small size, that sugar cube would be so dense, it would weigh as much as the entire human race. This core rebounds hurtling a shock wave through the skins of the star, as it punches the outer layer, this starts the element production line, smashing together new elements, all heavier than Iron. The shock wave then bounds through the star pushing the explosion which hurls the matter further and further out into space.

Without these supernovas, we would not have had life as we know it today in the universe. ‘Incredibly’ Lexi begins ‘the Hubble space telescope recorded pictures of these and sent them back to planet Earth, for scientists to explore. For you, my cosmic crew, you can witness these supernovas from the safety of the Venus-Valkyrie occurring some distance from the ship.

A Supernova collapsing and forming new elements

You admire from the ship, the changing colors and bright lights as the ginormous explosions happening within the young universe are forming the heavier much needed building blocks for life. Without those two hundred million stars exploding, we wouldn’t have any of the life that we so easily take for granted around us.

[The ship begins to grind and clunk as once again the core is thrust to life, the droids move seamlessly around the bridge setting the next time destination course…]

[The ship lurches to a halt and everyone is thrown back into their seats.] We now stand at nine billion years after the Big Bang and the universe has all the building blocks it needs to begin forming life.

The still young Universe filled with stars and galaxies.

It’s hard to believe that everything you are now witnessing around you, all came from that tiny orb all those billions of years ago. The universe has come to be a complex and expanding place, vast darkness filled with the light of billions of galaxies and uncountable stars.

From the platform of the Venus-Valkyrie, you see ahead a quiet corner of the Milky Way, where dust and gas in mass is beginning to accumulate. It’s rich debris left over from one of the supernovas and when it hits a critical mass it begins to burn brightly, a star is born. Our star, our sun in fact.

Solar System forming.

The left over debris from this star forming, forms a disk of swirling debris around the sun. Clumps of debris and gas are colliding together and beginning to spin in orbit, planets are being formed. One of the clumps of newly formed planet will evolve to become planet Earth, we are in our home solar system.

That concludes the first part of your curiosity journey my cosmic crew, Lexi says from the bridge. The captain makes her way to the crew seating and guides you through the process for the ship re-entering Earth’s atmosphere.

If you’re curiosity has been stoked and you’d like to join us on board for part two, the formation of our solar system, then I look forward to greeting you back on the Venus-Valkyrie in just a short while.

Please remain seated and keep your suit active until you have disembarked the ship. With that the engine roars to life, Lexi pushes the throttle ahead and lines the ship up for re-entry. This is the Venus-Valkyrie, we are go for re-entry.

Live long and prosper, my human tribe.
