It's interesting to consider the parallels between the electron's roundness and the cosmic microwave background (CMB) radiation's uniformity. Both seem to defy our expectations of asymmetry, with the electron's shape ruling out new particles and the CMB's uniformity challenging our understanding of the early universe. As we explore these seemingly unrelated phenomena, perhaps there lies a deep, underlying connection that could unite our understanding of the microcosm and the macrocosm, offering a fresh perspective on the laws governing our universe.

For the CMB we predict (or rather invent) "inflation" - a rapid expansion of the space-time to preserve uniformity of early Universe [1]. Inflation lasted for 0.00000000000000000000000000000001s but the size of the Universe increased by 10^30 times.

Edit: I wanted to come up with an analogy of increasing some object to the size of Earth (as it is the biggest object we can experience in real life). Though 10^30 times is so mindbogglingly large that we don't really have any sense of that small sizes at all. The object would have to be smaller than an electron by a trillion times (10^12).
