In the 2002 version of The Time Machine, the Time Traveller travels from the year 1899 to 802701.

During the time travelling sequence, the world around the time machine changes, but it changes around the machine itself.

If he was travelling through time, how would the world around him know or adapt and avoid the space that the machine was taking up?

Why wouldn't the materials occupy the same space as the Traveller, just not the same time?

    This opens up sooo many cans of worms... If it passed through solid matter while traveling, how did the time machine stay fixed to that one point on Earth while Earth rotated and revolved around the Sun? Would gravity then pull it to the center of the Earth, if it's still even affected by gravity? Did it instead displace matter while traveling, and if so, why wasn't it noticed by others? It hurts my head so much. =(

  • Is this a movie version of the HG Wells story?

  • A remake of the 1960's version. Directed by Simon Wells. The great grandson of H G Wells. Dec 20, 2011 at 21:22

The Time Machine creates a bubble around it when it is operating. Thus protecting it from the changes experienced outside the time bubble. It moves in both space and time, relative to its original starting point. It temporarily displaces the matter as it passes through it on its journey.

It seems to me in the original Time Machine that Alexander Hartdegen arrives inside a rock face at one point. The appearance of the Time Machine causes the matter that would have been occupying the space within rock to be gone. No evidence to suggest whether it was permanent or not.

When something is both inside the bubble and outside the bubble (like the necklace, hand, or Morlock) they experience both passages of time simultaneously.

This actually happened in the 1960 version as well. In both cases, for the earlier parts (when he's traveling to the "near" future), the time machine was placed in the house of the Time Traveler, and even though the house was abandoned for many years, it was never torn down. At best, it was boarded up and abandoned. It's quite possible it was just a matter of luck that the Time Machine never had anything get in its way during the early sequences of time travel.

In both movies, these short time travel sequences ended with a longer trip to the year 802701. In the 1960s version, the Time Machine is covered up by rocks, which presumably erode away through weather, in the 2002 version, the Time Machine is actually in the open, the Time Traveler can see the effects of erosion occurring around him. In both cases, continental movements probably would have dropped the Time Machine into the ocean by 802701, but that would have resulted in a much shorter movie.

In the end, both movies were based off the book written in 1895 which was an allegory about class division of the time, and the exact mechanics on how a time machine would need to work weren't exactly thought out. The best explanation is probably that the time machine has a built-in safety mechanism that prevents it from coming to a complete stop unless it has a clear area around it, and it somehow sticks to the surface of the Earth while moving (let's blame gravity for that one).

Fun fact: there was a 1978 made for TV adaption that ignored the whole "the machine stays in the same place the same time" which had the hero travel to the 1692 Salem witch trials and the gold rush in 1871.
