WebIt tells us that the expansion of the universe means it is the space between objects that actually stretches, causing objects (galaxies) to move away from each other. Furthermore, any light in that space will also stretch, shifting that … WebThis is a very common technique used to measure the radial component of the velocity of distant astronomical objects. The steps are to. take the object's spectrum, measure the wavelengths of several of the absorption lines in its spectrum, and. use the Doppler shift formula above to calculate its velocity.
