Is the universal expansion really accelerating?
Or time itself is slowing down?
Recently measurements of light emanating from supernovas in distant galaxies have indicated that universal expansion is accelerating.
The concept that time is related to expansion of space however gives a different interpretation. If we consider that time is due to expansion of
space then our local time is the slowest as compared to that of distant objects when the expansion of the universe was faster.
Once we take this factor into account then the relative blue shifting of light from distant supernovas as compared to their luminosity only
indicates that time was faster in the past as compared to our time now. As our local time slows in comparison to the past distant time the
universal expansion will appear to become faster. This however is an illusion due to measurement of the universal expansion from our slower
time and indicates the opposite that the universal expansion is actually slowing down.
Recently (December 2007) Professor José Senovilla, Marc Mars and Raül Vera of the University of the Basque Country, Bilbao, and
University of Salamanca, Spain have suggested a similar explanation for the observed accelerated expansion. [Jose Senovilla, Marc Mars,
