Just been watching this film (the origional) for the umpteenth time and got the urge to say what i have thought for ages about the principles of HG Wells principle of time travel and it is this.

the machine that George travels forward in time in does NOT merely "jump" from one time coordinate to another... it travels in a linear mode through time like we are doing now as we live our lives...its just that it travels faster through time than what we do..

so isn't it logical to assume that the machine occupies ALL moments in time between now and wherever he is travelling to?

SO. that means that the time machine will always be visible to the observer throughout its journey

If George travels 100 years into the future in 3 minutes. then he will be visible in that spot for the next 100 years..although the observers will age 100 years..george will not

If it takes George 3 minutes to travel that 100 years then he will only age 3 minutes whereas it will take the observer(s) 100 years to observe it taking generations in shifts to actually watch it happen
