Although you can calculate it, the best approach is to use a cosmological calculator with some standard parameters already input. Enter the redshift of the object you want to find the distance to, using the parameters suggested by the calculator, and it will return many distance measures, ...
The convention in astronomy is to call that "redshift 1.9". Astronomers subtract 1 from the actual enlargement factor and call what they get "z." So the actual expansion factor (which works for both distances and wavelengths) is z+1 and that is also the reciprocal 1/a of ...
which has a redshift of 7.5. Using this, we can determine distance by calculating how long the light has traveled to reach us. With a redshift of 7.5, that comes out to be about 13 billion years. You might think that means it’s 13 billion light years away, but 13 billion years ag...
with a mirror set up 5 miles (8 km) away to reflect it back to its source. Varying the speed of the wheel allowed Fizeau to calculate how long it took for the light to travel out of the hole, to the adjacent

The Origin of the Universe: A Shift in Thinking In 1929, Edwin Hubble noticed that light coming from almost every galaxy he studied was shifted, according to the Doppler effect, to the red end of the spectrum. He argued that only galaxies moving away from our galaxy could produce these "...
“One of my personal interests and reasons why I am excited about FRBs is to use them to study the intergalactic medium and the host galaxy interstellar medium gas (especially at high redshift), and combine that with other ways to study these media at other wavelengths,” Ryder tells Invers...
Astronomers used to think that all of the stars in theuniversewere part of the Milky Way, but that changed in the 1920s when Edwin Hubble, the American astronomer after whom the famous telescope is named, managed to calculate the distance of the Andromeda nebula (today known as the Andromeda...
The redshift-distance data (standard candles) falls along that curve. One could say so far mostly along the right half, e.g. from 0.4 to 1.0. But we also have a nice data point on the left end too, that comes from the red curve. The temperature of the gas that ...
Agree that if the redshift idea (elementary school science experiment) is correct in being attributed to an accelerating expansion of the universe then massive amounts of energy are required. This doesn’t make much sense in that nothing is observable or detectable. What makes some sense is tha...
