The fact that space is, by its very nature, not uniform at the smallest scales has profound implications for the Big Bang. The current leading theory for how space expanded after the Big Bang is Inflation, which basically says that in the early universe, the tiny speck of spacetime that was created in the first instant of the Big Bang stretched out very, very quickly. That tiny speck of space ultimately expanded into our universe, which is still expanding.
Now, the thing is, in the first moments after creation, the space expanded so fast that the normally invisible "quantum ripples" were magnified to the point of creating large-scale differences in temperature and density. These tiny but vital differences can be seen through a radio map of the sky, such as WMAP (which I'll link to in my sources). So it seems that the massive stretching of space, combined with quantum ripples, created the tiny differences in temperature and density that allowed our universe to form the way it is today!

Those "minute" differences are reflections of conditions in the known Universe that existed when?

It all makes me wonder, what would be the point of a lifeless universe?
According to the cosmological principle, the structure of the universe is uniform at its largest scale and its largest structures are theoretically limited to 1.2 billion light years across. This new discovery pushes that limit nearly five-fold.

Below is an illustration of how the same image might appear at different pixel resolutions, if the pixels were poorly rendered as sharp squares (normally, a smooth image reconstruction from pixels would be preferred, but for illustration of pixels, the sharp squares make the point better)

One question I would like to ask everyone because I am interested in your replies and rationale:
If the universe is a simulation, what is the purpose of the simulation?
I think this is about the third time I have answered this question. To experience whatever we choose, whatever we create, and to experience who we really are.
What I mean is, does the nature of this reality (as we know it) yield any clues about what is being tested (if anything)?
Nothing is being tested. Our theology says reality exists as a test. There is no test.
I don't have a good answer myself, but consider the true randomness that QM says exists at the quantum level. Consider the wave function itself. This is far different than the "Randomness by ignorance" that occurs at the classical level.
Why true randomness?
If the purpose of the simulation were merely to give people a realistic experience, it seems that the behavior of fundamental particles could have been far simpler than it is.
Can you please elucidate?
Also, I don't think the purpose is to drive out the true nature of celestial mechanics (such as The Big Bang, or planet formation, or black hole formation, etc.) because those things do not include conscious observers, and would not require the wave-function to collapse.
You know they don't include a conscious observer how?
Earlier I proposed that maybe it was originally a simulation of everything, and conscious observers were jacked into it later. That would explain the whole "Reality as VR space-time grid" thing we've talked about earlier in this thread.
Like I said, I don't have a good answer. But I am interesting in hearing yours.

I've always thought that the collapse of the wave function due to observation, reminds me of a kind of procedural generation.

Let's hope we never find the source code for this simulation, weird # might start to happen
