In the study, Inh Jee of the Max Planck Institute in Germany used a new method to measure the Hubble Constant, which scientists use to calculate the age of the universe. 1 mega parsec = 10^6 parsec and 1 parsec = 206265 AU. The Hubble constant is … The further we look into space, the further back we see in time. The Hubble constant indicates the rate at which the Universe is currently expanding, so although it is called a ‘constant’ it changes with time. The Hubble puzzle. Much evidence suggests that the universe is very nearly "flat", i.e., it is expanding at just about the right rate to expand indefinitely. The speed the galaxy moves away from us is directly proportional to the distance from us. in u/year/u, with u some unit of distance, at your choice. This is knows as 'Hubble's Law' and is described in the equation: In the equation, is the velocity of a receding galaxy, is the distance to the galaxy and is the Hubble's constant.

Remember though this is purely a mental exercise as the wrong value for Hubble's constant was given in the question. Hubble's constant is probably a little larger than the inverse of the age of the Universe. The top ranked scientific justification for building Hubble was to determine the size and age of the Universe through observations of Cepheid variables in distant galaxies. A Universe that expands more quickly needs to have less matter and more dark energy, and its Hubble constant multiplied by the age of the Universe will have a larger value. The Hubble constant (H 0) is one of the most important numbers in cosmology because it can be used to estimate the size and age of the Universe. This illustration shows the three steps astronomers used to measure the universe's expansion rate to an unprecedented accuracy, reducing the total uncertainty to 2.4 percent.

This scientific goal was so important that it put constraints on the lower limit of the size of Hubble's primary mirror. Hubble's constant is equal to velocity over distance. 1 AU = 149597871 km.

In physical cosmology, the age of the universe is the time elapsed since the Big Bang.The current measurement of the age of the universe is around 13.8 billion years (as of 2015) – 13.799 ± 0.021 billion years within the Lambda-CDM concordance model. Most people are trying to calculate the age of the universe using the Hubble constant but I have to do things the other way around. This is … Now think of big bang theory. The expansion rate of the universe is known as the Hubble constant. Hubble way. Thus, the inverse of H 0 is equal to the age of the universe. One way to check the Hubble constant is to compare its prediction for the age of the universe with the age of the oldest objects … A recent value of the Hubble constant H_0 is 71 km/sec/mega parsec. This invariant factor to be applied to the standard #H_0= 71# km/sec/parsec is #1.02 X 10^(-12)# Now, #1/(converted H_0)# Perfectly flat would mean that it would asymptotically approach a zero expansion rate, and not collapse back.

The explanation gives the computational details.. 1/(Hubble constant) is an estimate for the age of our universe. In this second edition, i convert #H_0 to age of our universe, in the .

This is only slightly off from the actual estimated age of the universe. The Hubble constant changes with time but stays approximately equal to 1/(age of the universe). They found the Hubble Constant, or the rate that the universe is expanding, to be 73.9 kilometers (45.9 miles) per second per megaparsec. Even with the a known value for the Hubble constant, the value projected for the age of the universe is model dependent. 1 over Hubble's constant is equal to distance over velocity that is equal to time. The age of the universe would be shorter than the age of oldest stars. The reason they are close is somewhat of a coincidence, for example in the standard Lambda-CDM model of the Universe, in the far future the age of the Universe will become vastly larger than the inverse of the Hubble constant, because H asymptotically approaches a constant value. The Hubble constant has not been easy to measure, and the number has changed several times since the 1930s, Kuo says. Three Steps to Measuring the Hubble Constant | NASA If the universe is flat, and dominated by ordinary or dark matter, the age of the universe as inferred from the Hubble constant would be about 9 billion years. It is called a “constant” because it is the same at all locations of the universe, plus its value doesn’t change noticeably on the time scale of human civilization.

The uncertainty has been narrowed down to 20 million years, based on a number of studies which all gave extremely similar figures for the age. Artwork by Sandbox Studio, Chicago with Ana Kova . The reciprocal of the Hubble constant H_0, 1/H_0 is an estimate of the age of our universe, after conversion of units for parity. I know the formula already = T = 1 / H. I have to calculate a range of what the Hubble constant could possibly be using the estimates of the universe age between 12 billion and 15 billion. The age of our universe is #1/H_0# years, where #H_0# is obtained .

This is a great instructional video on how to calculate the age of Universe from Hubble's constant. Right away, we have seen some fundamentalists jumping to the conclusion that the …
