1. Person A is in December 28, 2009 1:51pm PST at 23 degrees North and 8 degrees West.

2. At that instant, Person A time travels back in time to December 27, 2009, 1:51pm PST at 23 degrees North and 8 degrees West.

Where does the air that exists at time December 27, 2009, 1:50:59pm PST at 23 degrees North and 8 degrees West go when Person A comes 1 second later?

And where does the air that fills Person A’s previous place come from at December 28, 2009, 1:51:01pm?

You claim that this Law of Physics has “no bearing in time travel”, but I think the laws of physics should be considered. However, if we are going to consider all the laws of physics, than really time travel has no bearing.

As for Dexter, I wish John Lithgow survived the season and was off the grid because the FBI and police are looking for him.

How great would it be if he just drove off and Dexter found Debra like that after searching for Arthur all night and that’s how it ended. They don’t always have to kill the main bad guy after every season. It’s good to have a Joker for every Batman. A reoccurring villain.

People misunderstand the real meaning of this law. All this law states is when an object is occuping an amount of space another object cannot be there. It’s actually a pretty simple concept. If you fill a bathtub to the brim with water… when you get in it that tub the water cannot occupy that space with you so the water will rise and overflow out of the tub as you put more of your body in it. Same with walking down the street. The street is filled with air as you walk through, you push that air out of the way and that air fills in the space behind you that you were occuping.

It really has no bearing in time travel. Time Cop was the first movie I saw that totally misrepresented this Law of Physics. It’s not like if I go back in time and if the sneakers I’m wearing came into contact with those same sneakers in the past they will blow up or disappear from existence.

1. Sometime before the adult Lock showed up in the 50s, Richard acquired the Compass from somewhere (we don’t care where).

2. In 1954, Lock shows up on the Island (appearing from nowhere) and gives Richard another Compass that is the exact same as the Compass, only appearing 40 years older (from wear and tear!). Then Lock disappears.

3. Richard keeps the two Compasses with him.

4. Richard (in 2007) walks up to injured Lock (who has been time skipping but has not visited 1954 yet) and gives him the Compass that Richard had in 1954 before Lock showed up, which is now 40 years old (while keeping the Compass that Lock gave him, that is, because of the time looping, 80 years old). Lock disappears.

5. Richard keeps the 80 year old Compass with him and we don’t know what happens next.

6. Adult lock shows up in 1954 and go back to 3 above

We’re not talking about two exact copies of one person trying to occupy the same exact space at the same exact time. We’re talking about a person visiting one location and time at different points along their PERSONAL timeline. From that person’s perspective, their experiences are still linear. In this case, one Sawyer was a few months older, and in a different location on the Island than his slightly younger self. There’s not even a paradox, since they never encountered one another and did something to induce a paradox, like older Sawyer killing his younger self.
