How rapidly is the universe expanding?
The rate of the expansion of the universe is described as the value for H₀. Using different methods to determine H₀, we have a range of values:
So the number is somewhere between 67.0 and 77.0.
This web page provides the best way to resolve this conundrum, using Statistics!
In 1906, statistician Francis Galton observed a competition to guess the weight of an ox at a country fair. Eight hundred people entered. Galton, being the kind of man he was, ran statistical tests on the numbers, and discovered that the average of all the guesses was almost exactly the weight of the ox.
This collective guess was not only better than the actual winner of the contest but also better than the guesses made by cattle experts at the fair.
So we are going to collect all the estimates input to this web page, average them and display the result.
Enter a number between 67.0 and 77.0 with a single digit after the decimal point.
