Planning. Planning for successful weaning from milk to solid food starts from the time the calf first arrives on the unit â seemingly trivial matters such as fresh water and small handfuls of fresh starter feed can be offered from one week of age.
Answer Wiki. The best available information indicates that the age of the universe is 13.7 billion years. Hubble has helped to measure the age of the universe using two different methods. The first method involves measuring the speeds and distances of galaxies. Because all of the galaxies in the universe are generally moving apart, we infer that they must all have been much closer together sometime in the past.
Rates of radiometric decay, also by looking at the most distant detectable objects (galaxies about 14 billion light-years away). <br /> <br /> 1 light-year = the distance light travels in one year. If an object is 14 billion light-years away the universe must be at least 14 billion years old for the light to get to earth. <br /> Oh, also by estimating the amount of hydrogen that has been converted by stars into other heavier elements, etc.
