What 2 measurement are required to determine the Hubble constant?
Teaspoons and cups....
If the hubble constant H is larger at great distances then what is happening?
The Universe is expanding at an accelerating rate.
What provides powers for the Hubble space telescope?
Being in perpetual orbit, Hubble needs a power supply that is constant and needs little if any maintenance. Solar power fits that bill. Hubble is fitted with two twenty-five foot solar panels that produce 2,800 watts of power.
Who was the hubble telescope named after?
The Hubble Telescope was named after its designer Edwin Hubble.
Why was the Hubble Space Telescope related to Edwin Hubble?
Edwin P. Hubble is related to the Hubble space telescope because he suggested that we launch a telescope into space so they named it after Edwin's last name, Hubble.
How was the cosmoligical constant proved wrong by Hubble?
Albert Einstein's cosmological constant was proved wrong by Hubble as he proved the universe is expanding so it doesn't need a constant to stop it imploding.
How would you work out the Hubble constant if the earth is 12.5 billion years old?
The Earth is not 12 billion years old. It is more like 5 billion years old. Hubble's constant cannot be determined from the age of the Earth. Hubble's constant describes how fast the universe is expanding. It can be determined by looking at the redshifts of stars that are a known distance away. From the redshift, one can determine the velocity of the star. Then Hubble's constant is defined as follows: v=Hd where v is the velocity of the star, H is Hubble's constant and d is the distance to the star. The current accepted value of Hubble's constant is about 71 km/s/Mpc.
What relationship is identified by Hubble's constant?
h=vd
Why can't scientists calculate the hubble constant exactly?
I can't find the answer anywhere. Everywhere I look it just says that it's still not the exact value of the Hubble constant. Why?
When did science discover that all matter is in constant motion?
If the galaxies are meant, it is credited to Edwin Hubble and became known as "Hubble's Law".
Why the age of the universe equals 66.6 percent of hubble time?
As far as I understand, the projected age of the universe is about 99.5% of the estimated "Hubble time". The age is projected by applying a correction factor to the inverse Hubble constant. The correction factor applied depends on the value of the cosmological constant. The constant is derived from WMAP observation data, and valued at 0.976. For a flat universe without cosmological constant, the value would have been 0.666, resulting in a projected age 66.6% of the Hubble time.

Who was the Hubble named after and why?
It was named after Edwin P. Hubble (1889 - 1953) for his pioneering work in astrophysics. The Hubble constant is the basis for the determination of the size of the universe and an essential piece of the foundations of the Big Bang theory.
If the hubble constant H is larger at great distances then what is happening?
The Universe is expanding at an accelerating rate.
Why is it difficult to measure the Hubble constant H?
Both the speed and the distance of distant galaxies must be measured accurately.
What was Edwin Hubble's equation?
Hubble's equation states that the velocity at which various galaxies are receding from the Earth is proportional to their distance from us.The law is often expressed by the equation v = H0D, with H0 the constant of proportionality (the Hubble constant) between the distance D to a galaxy and its velocity v. The SI unit of H0 is s-1 but it is most frequently quoted in (km/s)/Mpc, thus giving the speed in km/s of a galaxy one Megaparsec away. The reciprocal of H0 is the Hubble time.
What provides powers for the Hubble space telescope?
Being in perpetual orbit, Hubble needs a power supply that is constant and needs little if any maintenance. Solar power fits that bill. Hubble is fitted with two twenty-five foot solar panels that produce 2,800 watts of power.
