>>12640199a scalar field caused inflation, which caused the size of the metric of space (length) to double between 90 to 100 times in the time between 1E-36 to 1E-32s.
2^90 is about 1.2E27
2^100 is about 1.2E30
so the volume grew
something from 1.9E81 to 2E90 times bigger.
That's like a proton's diameter growing to 1 AU.
