i know the origin of the celestial is vague and variable but i never heard this before
''The Celestials began as a human-like race from the same universe as Galactus, their hunger for greater knowledge was so immense that they developed at a rather quick pace, so quick that they reached the apex of technology and understanding of the Universe faster than they expected. With the threat of stagnation on the horizon, The Celestials became desperate to find something else they could study and learn from.
Their own bodies proved to be their salvation, because they had focused all attention on learning about everything else, The Celestials knew very little about the inner workings of their own unique biology. Thus began a long series of experiments that resulting in their ascension into immortal beings made of pure anti-matter energy. Unfortunately, their actions had resulted in the loss of their ability to reproduce and ability to maintain cohesion on a physical plane of existence.
To fix the latter problem, they built massive armored suits which they could control remotely from hyperspace in order to interact with the physical world, however the threat of stagnation was still approaching and then, the rotted pillars holding their birth-reality together collapsed. Apparently, their experiments had destabilized the very fabric of time/space, causing it to implode.
However, their actions also lead to The Enigma Force transforming Galan of Taa into Galactus, a young woman into the physical embodiment of the new Death Abstract and the rise of The Phoenix. Not only that but it had saved them from stagnation, with all of the new realities created in the wake of the original universe's death, they could literally do anything they wanted and feed their hunger for knowledge in the process.''
i mean like WTF
