the age of the universe to be 130.7 billion years old??

The Hubble constant may give us false information about the size of the universe.
The universe is probably no more than 13 billion light years in diameter but it could be much older than13 billion years.

It can help, but it depends on an assumption of the composition of the universe.
"An alternative approach to estimating is the age of the universe is to measure the “Hubble constant”. The Hubble constant is a measure of the current expansion rate of the universe. Cosmologists use this measurement to extrapolate back to the Big Bang. This extrapolation depends on the history of the expansion rate which in turn depends on the current density of the universe and on the composition of the universe."
"If the universe is flat and composed mostly of matter, then the age of the universe is
2/(3 Ho)
where Ho is the value of the Hubble constant.
If the universe has a very low density of matter, then its extrapolated age is larger:
1/Ho
If the universe contains a form of matter similar to the cosmological constant, then the inferred age can be even larger."

Are you taking a true-false test?
