I think there is a mistake in terminology. I think it is possible they used “Diameter” when they should have used “Circumference” for the 93 billion figure.
Those estimations are not accurate. In fact, they are just words invented by humans. “Experts”, who produce “estimations” have limited knowledge of nature laws.
It extends in all directions from where? Seems to imply that “where” is earth (our tiny planet) since earth is where the measurement is being done. Does this mean that earth is the center of the universe? What are the odds of that being the case if the universe is a random happening of an uncontroled space? Instead it would mean that there is a creator, a creator whose prime objective is the earth. IMAGINE THAT!
