kendra. i was reading a book and i found this on how to measure red shift:
its the lenghting of wavelength of light from an object (like a sun)
you remember the Doppler Effect? it just like that but with light - longer wavelengths cause light to shift to the red end of the spectrum (thus the name) so it is measured by the redness (or displacement of lines in the object's spectrum)
sidenote: strong gravitational force can also cause a red shift in light.
i hope this is what you were asking at lunch. i was having a freak out for no reason moment.
