Why does time slow down as you approach the speed of light?
Why does time slow down when we approach the speed of light? Does time really stop at the speed of light?
If time slows down as you approach the speed of light, then what time scale is light on? I see scientists saying that time will go slow in space. How can time go slow? Why is the speed of the earth slowing down? Why do we assume that travelling faster than the speed of light necessitates time travel? Given that time slows inversely to speed, does it follow that time should progress at a fixed "lower" rate at the speed of light and likewise that if an object is motionless in space, then time passes at a fixed "faster" rate, therefore Earth time can be measured as a ratio of these rates? What is time? Does gravity actually slow down time? Why does time pass faster (as we think) when we go to sleep? How does the gravity slow down time? Why does time feel like it goes faster as we get older? Why does time pass faster as you get older? If we somehow slow the motion of earth, does it mean we can slow the time and thus longer age? Is it true nothing can go faster than the speed of light? Why can't a body move faster than the speed of light? Why can't anything travel faster than the speed of light? At the boundary of a black hole, does time become so slow that light from it never escapes, or space becomes so large that despite the speed of light being the same, light is not able to escape? Is it really true that nothing can travel faster than the speed of light? What is the speed of time? Why does time dilation occur? Is it possible to slow down the time? Can speed of light decrease? Why can you not accelerate to faster than light? How do reflexes speed up and slow down the perception of time? Why does time seem too pass quickly as we get older? Is time dilation affected by the direction of movement? Why can nothing move faster than light? If we could travel faster than the speed of light, would time travel backwards? Days are longer but the year is getting shorter. Why is the the speed of the Earth's spin slowing while the speed around the sun is increasing? Is the speed of time the same speed as light? Will time seem to continue to speed up the older we get? Is it really possible that time slows down around massive objects (like a black hole) since time is not a physical quantity after all?
