WebThe only things known to cause red shift are gravity and moving away from the observer. Gravity doesn’t fit the case, and the red shift is greater the dimmer/further the objects are, so it certainly looks like the universe is expanding. 3 David Collins Web'Red shift' is a key concept for astronomers.
