I came across the extended Kardashev scale. It describes how civilisations progress and what we can expect for ourselves in the future. It would appear @Purple might have been right about God all along hehe. Anyway, enjoy.
Type 0 civilization- We extract energy from crude organic based sources eg food, fossil fuel, wood. We are capable of orbital space flight. This is where we currently are in the 21st century earth.
Type I- we can extract all energy available to earth. We control the earth and weather, have colonized the moon, found aliens and cured aging. Space travel is now available to most people. We are mining asteroids & terraforming other planets and making them habitable.
Type II- We control the entire solar system and can harness the energy of a single star. Interstellar travel is now possible. The Dyson sphere (extracts all energy of the sun) is made, Matrioshka brain (star-sized computer) is made.
Type III- We extract energy from our galaxy and are capable of intergalactical space travel via wormholes.
Type IV- We can harness power from our own supercluster of galaxies and are basically immortal. Life can no longer die. Teleportation is discovered. Time-travel to the future is now possible.
Type V- We can extract energy from the whole of the universe. Later, we even discover other universes and subsequently, the multiverse(a space where a collection of universes exist). Later, the Megaverse (a space where a collection of multiverses exist) is discovered.
Type VI- Omniscience is almost achieved. We now exist in the multiverse and are capable of creating and maintaining the fundamental laws of each universe. We can create and destroy universes. We have mastered time travel. We can travel back to the Big Bang. We can make big bangs for universes happen.
Type VII-
We would travel, transcend and ultimately oversee or ‘‘be’’ the Omniverse which is the collection of every single universe, multiverse, megaverse, paraverse, dimension (alternate or pocket) and realm. Everything is in the Omniverse, and there is only one Omniverse.
It is likely that such power would come from an individual rather than a civilization, as the civilization would have transcended and merged into a single mind that would encompass all thoughts and all timelines, thus being omnipotent, omnipresent, and omniscient. This is the Creator: a god above all gods, responsible for all of existence, past and future.
As a god, we would visit our past selves in the earlier civilisations, try not to reveal too much but just enough to ensure they follow the same path as we did.
