Fasting can be very severe. From dawn to dusk (or from the time it's possible to distinquish a white thread from a blue one) observant Muslims neither eat not drink, not do a number of pleasurable things. This is to build strength of character, so that one can endure in his devotion. As the Prophet observed, "Fasting is half of discipline; discipline is half of faith."
The observed redshift in the spectra of galaxies indicates that they are moving away from us, which supports the theory of an expanding universe. As galaxies recede, the light they emit stretches to longer wavelengths, shifting toward the red end of the spectrum. This phenomenon is a key piece of evidence for the Big Bang theory, suggesting that the universe has been expanding since its inception. Additionally, the degree of redshift can help astronomers determine the distance and velocity of distant galaxies.
