Bonjour,

From what I red (understand??), the Hubble constant is calculated from galaxy's distance (from us and each other).

1) Is the information speed limit (c) considered constant althrough (through out??) the path?

2) Is the distance from us mesured using redshift only?

3) When mesuring galaxy's separation speed as 70 Km/sec for each megaparsec of distance from us, (a) may I interpret that separation speed being also in the direction from us and also (b) considered 6.8E-10 meter/sec

P.S.: h

^{2}being the galaxy's acceleration versus the time frame.P.S.: h

_{0}= ( H_{0}* 1000 * c )/ 3.086E+22[meter/Mparsec]
