Which mechanism stretches observed wavelengths due to spacecraft movement through spacetime?

💡 Explanation

Gravitational redshift lengthens wavelengths, acting as a form of time dilation observed by shifted spectral lines because photons lose energy escaping a gravitational field. Therefore redshift occurs, rather than blueshift, because the spacecraft's relative position in spacetime impacts the observed light.
