Nope. Volume has units of length cubed and area has units of length squared. Now, it is unusual to write an area with two different units of distance, but possible. (After all, US civil engineers and water management people measure volumes of water in "acre-feet" which is a volume of water covering 1 acre (an area) to a depth of 1 foot. It might be unusual, but it is sensible for water management. If you have a 55 acre reservoir and it increases by 2 feet then 110 acre-feet of water has been added.)That's the mistake all make. Don't forget volume or area has a single dimention of distance, which in the Ho case is light years.
Ho is not measured in light years by actual astronomers. They don't use "light years" in their reports. Astronomers measure stellar and galactic distances in parsecs (pc) or prefixed multiples (kpc, Mpc, Gpc). The other units of distance astronomers use are astronomical units (AU, for planetary orbits), solar radii (R_sun, for stellar sizes), km (for comprehensibility), and cm (they prefer cgs units to the SI's mks). Ask an astronomer about the path of the Sun about the Galactic center and they will tell you: "a roughly circular orbit of 8.5 kpc at a speed of 220 km/s".
Hubble's constant is the slope of a plot of distance (in Mpc) in the horizontal axis and recession velocity (in km/s) in the vertical. Thus the units of H_o are [km/s] per [Mpc]. The dimensionality of the constant is actual [1/time] and if properly converted between km and Mpc, to be in [1/s] the age of the Universe is approximately 1/H_o.
At this point no one can tell what you are ranting about. There has been no "escaped gas" discussed in this thread. It is about the expansion of the Universe and your failure to understand units.What area or volume did the excaped gas leak out to? You can legitimately say it spread out to 2 miles distance. You CANNOT legitimately say it spread out to 2 hours. That would be nonsense. So you are wrong, are you not???
