"Inflation became popular, though, because it solves several problems."These problems being:
- space (as measured) is flat, although it should be curved (to remove the notion of a "center")
- space is uniform at the macro level, but non-uniform locally (space should be uniform throughout, or non-uniform throughout - uniformity implies structure or communication)
“If you want quantum fluctuations to explain all the structure in the universe, you need something like inflation”Or you could make up a lot of stuff that hasn't been measured (or even better, can't be measured!)
Like inflation, and then dark energy to drive the inflation.
