Answer:
thry mearsure the distance to the farthest galaxy
Answer2. The age of the Universe is around 16 billion light years away or old.
There are three completely independent means of measuring the age of our Universe, and all result in about the same age of 12 to 15 billion years:
1) Once a white dwarf is formed, it will remain stable for trillions of years. None have been found older than twelve billion years, however.
2) The inverse of the Hubble Constant -- ie, the time all matter in our observed Universe would return to sub-atomic size -- is about thirteen billion years.
3) Ratios of long-lasting radioactive isotopes to their decay products give close to the same value as (2).
