So you are saying the pilot would hallucinate for a year? Because you and I are not hallucinating when we look at the years worth of pictures collected during the year long experiment.
The pilot can hop out of that car saying whatever he wants to...we have him on camera...we have the proof...it doesn't matter what he "experienced"...we saw the condition of the car he was traveling in every few miles down the track...we know it was exposed to the elements whilst it moved...we know he needed food, we know he would grow a beard...we knew before we started the test. We put the food and everything he would need to care of himself for a year in the car...we built it into it.
It moved a said distance in a certain amount of time. We have the pictures to prove it. The car and pilot did not go into another dimension...it stayed on the track, and the pilot inside stayed alive..we have the pictures to prove it. I don't care what the pilot says, we had our eyes on him the whole way...and we can prove he is lying...no matter how long he said the trip took...he hallucinated...and we can prove it.
I think it is tricky a bit, to take pictures of the process. Either you view the process out of the car, stationary in the ground, or you'll view it in the car. But, let's assume for a moment that you have that much equipped camera and you take picture of the pilot for a whole year.
You will take pictures for one whole year yes, that does not mean the pilot has hallucinated, in his time it was not one year, but maybe two weeks had passed. It is hard to grasp, but this time dilation phenomenon is observed many times. Time is just not independent of the observer. Each one will measure a different time gap in their own frame of the same process.
Now, the tricky part is, you see the pilot for the whole year, so how come does he not age thusly (say why not he doesn't have gandalf the gray beard) ?..Now, in order to understand this problem, you have to believe that: 1) 1 year had passed in ground observer's frame, 2) 2 weeks had passed in pilot's frame..
This is an observed fact, if you move with high velocities time passes slowly for you, so you better believe it. Now, generally in such problems, we talk about the clocks of the ground observer and the pilot, and compare them. In this example you have elevated the observation process such that the ground observer is able to observe the face of the pilot. Well, what then? What happens in those pictures taken for 1 year.
Something extraordinary happens, you will observe a 2 week long process elongated to 1 year long time interval. So, what you will see is something like a slow-motion 2 week process which takes 1 year to watch. Thus, rather then comparing clocks which is boring, you have actually seen the time dilation phenomenon with your eyes!
In short, you have taken pictures of the pilot with a Sean Connery beard, not Gandalf's..Isn't it amazing?
There will be exactly one years worth of damage to the car...it will be exactly one year older as a result. Moving the car around for a year probably made it get damaged a lot quicker. It may have stayed in good condition for a really long time if it just stayed parked in the bay. However...whether it stayed put or moved real fast...a year passed by...and it is what is after that year...it was physical for the whole year, and therfore all laws of physics were applied to it...no matter how fast it moved around for that year. No defying the laws of physics with enough speed.
There exists no speed at which the laws of physics are defied..it was the laws of physics which allowed the speed of said object in the first place.
When the object starts disobeying the laws of physics...is when the object begins to be destroyed by the laws of physics...
If you move faster and faster...you become destroyed faster and faster until you fizzle out completely...so your time machine motor broke down a long time ago.
Newton told you it had to move to cause a movement. And the faster it moved...the faster it broke down...so you have just destroyed your chances of time travel because you sought to achieve it through moving an object faster and faster...the very thing which would destroy the object and destroy all chances of achieving time travel...
Let's say your ship doesn't have fast moving parts...it just sits there and humms....well...do you see the environment around the ship moving around real slow? Say we are standing in a hanger where the ship is parked and humming away...is it causing us to walk around the ship real slow..like we are caught in a time warp?
Is the pilot in the ship seeing us walk around the ship real slow, even though we are really walking around the ship like normal?
My point is simple...physical objects obey all laws of physics no matter how fast they move, or how slow they move. It's like a temperature scale....really slow moving objects are really cold. Really fast moving objects are hot.
But neither go through a year without actually going through the whole year...fast or slow...they are still here for a year under the laws of physics...
Well, we have just conducted a "gedanken experiment" which was highly theoretical. You cannot build a ship or a car which reaches such velocities, just because it would consume tremendous amounts of energy. And doing this in a planet with an atmosphere would indeed cause decay due to friction. So, just do it in outer space, where you wouldn't observe any decay.
No matter fast any object moves, laws of physics are obeyed, as you say. This is actually a postulate of Special Theory of Relativity. Space ship moving for two weeks, yet us observing it moving for 1 year does not change this fact. As I have said, time is dependent on observers and each one will measure something else, but the physical laws are all going to be same! It is the beauty of physics, there are symmetries which allow us to move from one frame to another. Certain things change when you change the frame but no problem! Because you would have the right recipes to transform between them.
