I NEED HELP WTH LETTER JUST LETTER B. I CANNOT FIGURE IT OUT. PLEASE HELP.

Hubble's law gives us a way to estimate the Assuming the universe began expanding when it came into existence and that it has always expanded at a constant rate: (b) What would the age of the universe be if the Hubble constant was measured to be 60 km/s/Mpc? As of 2014, the most accurate measurement for the age of the universe is billion years. In 1927 proposed that the universe is He proposed that the universe began as an This energy created at the beginning of time caused the universe to This initial event is now called the primordial atom of energy. , and it created It led to the formation of all and Science does not have an explanation for why Shortly after World War II, proposed that a fraction after the Big Bang, the universe was an - in excess of 10 K 32 The early universe must have been filled with intensely electromagnetic radiation (gamma-rays) As the universe expanded, the cosmological redshift stretched these gamma-rays to longer and longer wavelengths so that most of the photons left over from this event are now Because the early photons are being redshifted, the energy the each have is This energy is measured as heat, so the universe is as it expands.

Explanation / Answer

H0= 60km /s/mpc or 60 * 0.032394*10^-18 = 1.94364 *10^-19 s-1

age = 1/ Ho= 1/1.94364*10^-19 s^-1)= 1.6*10^11 years
