#H_o=71# km/sec/megaparsec

Explanation:

An excerpt from pp 144-145 of the essay #10. Esoteric Science

About Universe and Creation, 'Faiths and Proximate Truths (2010)', A.

S. Adikesavan:

...All galaxies appear to be receding from one another. Any space

location or motion is relative, and there is a fourth dimension,

time.

Galaxies motion is described as motion of islands in space. And the

velocity of a galaxy is estimated by the Doppler effect ( light

emitted from a source is shifted in wave-length, by the motion of

light source).

In respect of this motion, Edwin Powell Hubble (1889-1953) had

discovered a linear correlation between speed and distance (rate

of change of speed with respect to the distance is constant):

The Linear Velocity = #H_o# X Distance Here, #H_o# is called

the Hubble constant, that was originally thought of as 75, and now

revised as 71 km/sec/mega parsec (parsec = 3.26 light years). For

this value, the expansion time (reckoned from Big Bang (BB)) of

our universe is estimated as #13.77 X 10^9# years. ... ..:
