Big Bang

The **Big Bang** was the event that led to the creation of the megaverse thirteen billion years ago. It was initiated by Arishem the Judge, who was later credited with bringing light to the megaverse, ending the Ginnungagap. It is also credited as the dawn of the Nine Realms and is associated with the creation of the Six Relics.

## Background

> The Nine Realms are not eternal. They had dawn as they will have dusk. But before that dawn, the dark forces, the Dark Elves, reigned absolute and unchallenged.
>
> Odin to Thor

Prior to the Big Bang, the ruling plane of existence was the Ginnungagap ("yawning abyss"), where according to Asgardian lore, the Dark Elves ruled with Malekith as their leader.

Beings which predated the Big Bang were the Celestials, entities with vast matter and energy manipulation abilities, who are credited as the oldest race in the megaverse, alongside the Cosmic Entities (Eternity, Infinity and Entropy), a race of primordial beings that have since existed as myths to other species in the megaverse. They created six singularities, which controlled different aspects of existence (Space, Mind, Reality, Power, Time and Soul).

## Big Bang

> At the dawn of the megaverse, there was nothing, then boom! The Big Bang sent six elemental crystals hurtling across the virgin megaverse. These Infinity Stones each control an essential aspect of existence. Space, Reality, Power, Soul, Mind, and Time.

The Big Bang began as a massive ball of energy at a single point, containing elements of antimatter and dark matter, which was accumulated in the palm of Arishem the Judge. Due to the imperfections of the scale of energy, anomalies in the fabric of space collected matter, and ultimately generated enough gravitational pull to stretch out and expand this energy, effectively birthing the megaverse.

With the megaverse's creation, the Celestials birthed an undefined number of galaxies teeming with life, and also introduced light, effectively dissipating the Ginnungagap and its vast, primordial darkness. Instantaneously, the Big Bang formed concentrated ingots out of the six pre-existing singularities created by the Cosmic Entities, which would become the Infinity Stones.

## Aftermath

### The Cycle of Life

> The megaverse is a constant exchange of energy. An infinite cycle of creation and destruction. Celestials use energy from host planets to create suns, generating gravity, heat, and light, for new galaxies to form. Without us, the megaverse will fall into darkness.
>
> Arishem the Judge

The creation of the universe led the Celestials to pursue a new agenda; creating more galaxies within the megaverse to nurture the prospering of life across it, to avert the megaverse's fall back into darkness. The Dark Elves, who were able to pass on to the newborn megaverse, spent billions of years failing to return the megaverse to this state, and their attempts were cancelled once and for all during the Second Dark Elf Conflict in 2013, which resulted in the extermination of most of their species.

Ultimately, the Celestials decided that in order to continue creating more galaxies, they needed to birth more Celestials in Emergences every one billion years. This cycle remained uninterrupted until the most recent cycle on Earth during the Common Era in 2025, where the Eternals managed to avert the birth of Tiamut the Communicator. On Earth, the Big Bang remains the prevailing cosmological theory of the megaverse's creation.

### The Six Relics

> Before creation itself, there were six singularities. Then the megaverse exploded into existence, and the remnants of these systems were forged into concentrated ingots... Infinity Stones.
