I have become very interested in physics and astronomy recently and have started dabbling. I have been reading about curved space time and its association with gravity. I've also been reading about time as it is related to travel at the speed of light. Can anyone explain the concept of curved space time using some type of simple analogy that might stick with me? Also, why is it that time slows as we near the speed of light? Are the two related? Thanks for being patient with someone who crunches numbers for a living!
