Also, very early on, the Dutch astronomer, Jan Oort, thought something was wrong with Hubble's scale and published a value of 290 km/s/Mpc, but this was largely forgotten.

WebThe inverse Hubble constant therefore provides the approximate age of the Universe in seconds, which can then be converted into years (1 year = `3.154` x `10^7` seconds). Click the Calculate button and enter your value of the Hubble constant to calculate the age of the Universe from your measurements. The Hubble constant has units of inverse time; the Hubble time tH is simply defined as the inverse of the Hubble constant, i.e. This is slightly different from the age of the universe which is approximately 13.8 billion years. The Hubble time is the age it would have had if the expansion had been linear, and it is different from the real age of the universe because the expansion is not linear; it depends on the energy conte… tt networks
