H0LiCOW: Cosmoboffins still have no idea why universe seems to be expanding more rapidly than expected


Re: Riddle me this:

The Hubble constant is the reciprocal of the age of the universe, about 1/(14,000,000,000 years). Since my height is rather less than 2m and my age about 70 years, over my lifetime the expansion of the universe has increased my height by about 2*70/14,000,000,000 m, that is 10^-8 m or 100 Angstroms.

Of course, local space-time is heavily distorted by all of the matter around me, so this calculation is only illustrative.
