The concept of time as a way to measure the duration of events is not only deeply intuitive, it also plays an important role in our mathematical descriptions of physical systems. For instance, we define an object’s speed as its displacement per a given time. But some researchers theorize that this Newtonian idea of time as an absolute quantity that flows on its own, along with the idea that time is the fourth dimension of spacetime, are incorrect. They propose to replace these concepts of time with a view that corresponds more accurately to the physical world: time as a measure of the numerical order of change.
Caltech physicist Sean Carroll recently tweeted that he was meeting up with Lost producers Damon Lindelof and Carlton Cuse. This was posted to the forums at Lostpedia, prompting immediate spoiler complaints ... so Carroll signs up and drops in to the thread to clear up the confusion, also offering some of his thoughts on the use of time travel in the show and referencing a longer blog post he wrote shortly before the start of the final season.
