Does "real time" actually exist? If so, then what is it?

Question

How can anything possibly exist in the exact same time? This may seem like a dumb question to some of you, but I really am having some difficulty wrapping my mind around it.

Answer 1

Picture a city on level ground built on a rectangular grid array of streets and avenues.  There's no limit to how many streets you could be on, and still be on fifth avenue.  And if you're on fifth avenue and third street, there's no limit to how many feet above ground elevation you can be.

Just as the three perpendicular spatial dimensions are independent of each other, time (the temporal dimension) is independent of the spatial dimensions.

Once you get to relativistic speeds, it's not quite that simple, and you need to consider all four dimensions as a single spacetime.

Answer 2

well i took physics and philosophy before and i can try to help u anwser this question...this is no set definition of "now" because once you say and event happened now it turns into the past in the next second real time can really only be considered as the second it instantly happens because the second after the "now" happens, it then turns into the past  

Answer 3

The speed of light is 186.000miles per second. That's as "real" as it gets.Are you asking a philosophical question?Do you exist? does the room you are in? Can you measure time in the room? Figure it out then move on and worry about what's for supper.
