It is equivalent to 4,550 million parsecs or 14.4 billion light years.
Calculating the Hubble time!!!? Hubble’s original value for H 0 was 150 km (93 miles) per second per 1,000,000 light-years.
Hubble telescope looks back in time to see far-off galaxies. Other articles where Hubble time is discussed: physical science: Astronomy: …and later increased the “Hubble age” of the universe to more than 10 billion years. We’ve said that the Hubble constant H is about 75 km/sec/Mpc. Since both km (kilometers) and Mpc (megaparsecs) are units of distance, they cancel if you do the unit conversion right, and H’s units really work out to 1/time. The Hubble length or Hubble distance is a unit of distance in cosmology, defined as − — the speed of light multiplied by the Hubble time. The Hubble Expansion During the 1920's and 30's, Edwin Hubble discovered that the Universe is expanding, with galaxies moving away from each other at a velocity given by an expression known as Hubble's Law: v = H*r.Here v represent's the galaxy's recessional velocity, r is its distance away from Earth, and H is a constant of proportionality called Hubble's constant. Hence, the reciprocal of Hubble's constant gives you a time (the age of the universe in seconds) Hubble's constant in SI units is 1.62… ... Hubble took this image by gazing deep out into the cosmos at the galaxy cluster Abell S1063, the bright smudge you can see at … Modern estimates, using measurements of the cosmic microwave background radiation left over from the big bang, place the value of H 0 at between 21.5 and 23.4 km (13.3 and 14.5 miles) per second per 1,000,000 light-years.
The units of your final answer should just be s^-1.
