Q.How would I convert Hubble's constant in "km/s/MPc" units into "s^-1 units"?
A.To convert Hubble's constant from (km/s)/MPc to units of inverse time, divide by the km in a MPc (3.086x10^19). Eg 74.2 (km/s)/MPc = 2.40x10^-18 s^-1.
A.Hubble's constant is the rate of recession of astronomical objects, per unit distance away. The current constant between galaxies is 71kps/megaparsec.
Q.What is the formula for calculating the age of the universe?
A.The age of the universe is determined by measuring the Hubble constant and extrapolating back in time with the observed value of density parameters.
Q.Where is the hubble telescope
A.The Hubble Space Telescope orbits the Earth 220km above the surface and takes about 1.5 hours to complete one orbit. It was launched in 1990.
