Introducing Time

What is time? The 5th-century philosopher St Augustine famously said that he knew what time was, so long as no one asked him. Is time a fourth dimension similar to space or does it flow in some sense? And if it flows, does it make sense to say how fast? Does the future exist? Is time travel possible? Why does time seem to pass in only one direction?These questions and others are among the deepest and most subtle that one can ask, but “Introducing Time” presents them — many for the first time — in an easily accessible, lucid and engaging manner, wittily illustrated by Ralph Edney.

    Wow! Blew my mind. I can’t even digest most of it. Will revisit from time to time. Hopes up.

    hanks to general relativity, the science of spacetime, we can now rigorously investigate questions about time travel, branching time, and so on.

    That is, we may receive the answer before we even ask the question…
    In much the same way as we encountered when discussing time travel.

    The event corresponding to what you will do after you read this sentence does not exist. The future is unsettled and ripe with possibility.
