+ | This comic is a reference to the phenomena known as redshift/blueshift. Due to the Doppler effect, objects that are moving toward an observer appear bluer than they actually are (known as blueshift). Objects moving away from the observer (e.g. objects viewed in the rear-view mirror of a moving vehicle) appear redder than they actually are (known as redshift), and thus the objects are in reality bluer than they appear. This is generally relevant only in terms of high speed motion such as observation of the expansion of the universe in astrophysics. The joke is that the relative speed of any object visible in a rear-view mirror would create an insignificant and unobservable redshift. | ||
− | + | Edwin Hubble was an astronomer credited with "Hubble's Law," which states that a Doppler shift can be observed for objects in space moving with relative velocity to Earth. | |
