Suppose it was discovered that Hubble's constant, H0, was smaller than previously thought. How would this affect our estimate of the age of the universe?

Answer:

The age of the universe would be larger.

Step-by-step explanation:

The Hubble relation states that an astronomical object's velocity is proportional to the distance between the observer and the object.

v = dH₀

where

  • d is the distance between the observer and the object.
  • H₀ is the Hubble constant

If the Hubble constant decreases, the velocity will decrease.

Time is determined by taking the quotient between the distance and the velocity.

T = d/v

Therefore, since the velocity decreased, the time increases. Thus, if H₀ was found to be smaller than thought, the age of the universe would be larger.
