Estimate the speed of a galaxy that is 10 billion light-years away.
The correct answer is .5c. Can someone show me how it was calculated?
To calculate the speed of recession of a galaxy that is 10 billion light years away, we need to plug in the value of the Hubble Constant (H0) in the formula v = d * H0, where d = Distance of the galaxy from the Milky way.
The Hubble Constant is not really a constant because it is a function of time. ...
