"Before the dawn of time, Order and Chaos existed within an extra-dimensional entity known as The One. To explore the fledgling universe, he created the astral being known as Unicron, and then subdivided him, creating his twin, Primus. Both brothers were multiversal singularities, unique in all realities, but whereas Unicron could only exist in one universe at a time, moving between them at will, Primus existed simultaneously in all realities at once. It is suggested, in fact, that the two brothers embody the basic concepts of reality—good and evil, order and chaos—and that their continued existence is necessary for the stability of the multiverse."
Be at peace with this. I'm not sure how what anyone is saying is relevant to the topic:
Shadowpanther said: So their is no such thing as a planet that can be created out of 100% metal.
For a celestial body to be classified as a planet it must have orbit around a star, a shape that is stable due to its own gravity and one that has a dominant path over neighboring bodies in it's orbit.
Asteroids are not classified as planets. Primus slammed into an Asteroid and reshaped it to his favor. To be classified as an asteroid it only needs to have an orbit and mass and otherwise not fulfill the requirements to be a planet, dwarf planet, moon or comet. With that being said, it is not unfathomable to find an asteroid comprised entirely of metal that is large enough to contain a massive cosmic entity of unlimited power. Also, he has unlimited power, he could bring metal from elsewhere or who is to say that he could not simply re-arrange molecules and create the metals he desired from other raw materials (such as the key to Vector Sigma does). Also remember that Cybertron isn't Primus' first rodeo. He first experimented on Methuselah's moon Protos.
There is no theory to the origin of Cybertron, we know it. In summation: The One made Primus, Primus smashed into as Asteroid which he then shaped into a planetoid body later called Cybertron. The end.
And also not all planets are comprised of the same materials found on Earth. Some are completely devoid of various things. For instance it is impossible to know whether or not Jupiter has a surface. It could be a highly dense ball of gas. Saturn is actually less dense then water and would float if you could get it into a body of water large enough. Suffice it to say the universe hold infinite inpossibilities. To claim we know "all" of anything is laughable.
I want everyone to take home this homework. Read it carefully.
One googol is presumed to be greater than the number of hydrogen atoms in the observable universe, which has been variously estimated to be between 1079 and 1081. A googol is also greater than the number of Planck times elapsed since the Big Bang, which is estimated at about 8×1060. Thus in the physical world it is difficult to give examples of numbers that compare to the vastly greater googolplex. In analyzing quantum states and black holes, physicist Don Page writes that "determining experimentally whether or not information is lost down black holes of solar mass ... would require more than measurements to give a rough determination of the final density matrix after a black hole evaporates". The end of the Universe via Big Freeze without proton decay is subject to be years into the future, which is still short of a googolplex.
In a separate article, Page shows that the number of states in a black hole with a mass roughly equivalent to the Andromeda Galaxy is in the range of a googolplex.
years (~ googolplex years) — scale of an estimated Poincaré recurrence time for the quantum state of a hypothetical box containing a black hole with the mass within the presently visible region of our universe. This time assumes a statistical model subject to Poincaré recurrence. A much simplified way of thinking about this time is in a model where our universe's history repeats itself arbitrarily many times due to properties of statistical mechanics, this is the time scale when it will first be somewhat similar (for a reasonable choice of "similar") to its current state again.
years (~ googolplex years) — scale of an estimated Poincaré recurrence time for the quantum state of a hypothetical box containing a black hole with the estimated mass of the entire universe, observable or not, assuming a certain inflationary model with an inflaton whose mass is 10−6 Planck masses.
If the entire volume of the observable universe (taken to be 3 × 1080 m3) were packed solid with fine dust particles about 1.5 micrometres in size, then the number of different ways of ordering these particles (that is, assigning the number 1 to one particle, then the number 2 to another particle, and so on until all particles are numbered) would be approximately one googolplex.
Essentially you would have better odds of finding an ACTUAL Cybertron, or an exact duplicate of Earth where EVERYTHING was the same right down to you as one of it's residents... BEFORE you reached a googolplex. It makes you contemplate your place in the universe and really realize how trivial debating the origins of a fictional planet may be.
