I understand that expansion of space has been known since Hubble. Then in 1998 it was discovered, by observations of supernovae, that the expansion was accelerating - the popular explanation being a kind of negative pressure (dark energy), possibly vacuum energy. That, as far as I knew, was the unexpected part of it. Now you're telling me that the acceleration is greater than expected. Oh boy, weirderer and weirderer smile
