How Old Is the Universe?
... to a distance of 1 billion light-years or more. When we achieved that goal,
astronomers predicted, we would find that the value of H had in the distant past
been larger than the current-day value of 74 kilometers per second per
megaparsec.
Durante várias décadas, os dois métodos observacionais de cálculo da idade do
universo diferentes não puderam ser conciliados. Astrônomos expressam a
constante de Hubble em quilômetros por segundo (velocidade) por megaparsec

History of Shock Waves, Explosions and Impact: A ...
Since the late 1950s astronomers have been arguing for an H0 value of between
50 and 100 km/s/megaparsec, where one ... s/megaparsec, as recently
determined with an uncertainty of only 10% (itself a milestone achievement in ...

Cosmology: The Science of the Universe
In other words, the recession velocity increased with distance by 150 kilometers
per second for every million light years (or 500 kilometers per second for every
megaparsec). In 1 952. Walter Baade discovered the two stellar populations.
5
The Extravagant Universe: Exploding Stars, Dark Energy and ...
For H0 = 70 kilometers per second per megaparsec, this is 1 X 10~26 kilogram
per cubic meter — a very low density, indeed! Then Q is the actual density
divided by the critical density, so it is exactly one when the observed density is
equal to ...
6
The Cosmic Keyhole: How Astronomy Is Unlocking the Secrets ...
Now, if you do the math and manipulate the relationship that Hubble discovered (
we will not go into that here), it tells us that the universe is expanding at about 80
km a second for every megaparsec, with an error of plus or minus about 17 km/s
...
7
Astronomy for Entertainment
But soon the kiloparsec was found inadequate and astronomers were obliged to
introduce the "megaparsec," which equals one million par- sees. Here is a table
of stellar units of length: 1 megaparsec =1 million parsecs 1 kiloparsec =1 ...
8
The Universe at Midnight: Observations Illuminating the Cosmos
If astronomers could determine the Hubble constant's numerical value, it would
state how much galaxy redshifts (in kilometers per second) increase for every
megaparsec farther an astronomer looks (one megaparsec is 3.26 million ...

The result is V0 = 585 km. per sec. per megaparsec. The actual speed should be
rather less than the limiting speed, but the difference is not very important* The
observed value, found by Hubble and Humason, is 560 km. per sec. per ...
