− | The | + | The Hydrogen Line is a frequency of the electromagnetic spectrum with a frequency of ~1.4 Gigahertz (GHz) that neutral (unionized) hydrogen atoms emit. The wavelength of light for the line is about 21.1 centimeters, giving it the common name of the 21-centimeter line. In this comic, Ponytail is attempting to detect the signal of this emission line from the ancient universe, although due to redshift, the line's frequency has decreased from 1.4 GHz to only circa 100 Megahertz (MHz), putting it within range of FM radio, one of the two types of radio waves used by radio stations, for example, to broadcast audio. FM Radio mostly makes use of frequencies of of 87.5 to 108.0 MHz. |
− | + | The fact that the signal Ponytail is searching for and FM radio overlap in frequency quickly becomes an apparent problem when tuning to the frequency detects a local radio station rather than the desired signal. | |
