How is Hubble's Constant calculated?

Answer 1

Claire Anctil

The formula #H=v/d# can be used.

The size, age, and rate of expansion of the universe can all be ascertained using the Hubble Constant.

It is difficult to determine the Hubble Constant's actual value.

It takes two measurements.

Next, the formula that follows is applied.

#H=v/d#

The calculation uses kilometers per second per megaparsec as its units.

Ian Aitchison

The formula used to calculate Hubble's constant is v = H0 * d, where d is the galaxy's distance from Earth, v is its recessional velocity due to the expansion of the universe, and H0 is Hubble's constant. Typically, the redshifts and distances of distant galaxies are measured.

Answer from HIX Tutor

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
