[QUOTE="Channel Hopper, post: 18197, member: 175144"] [B]Then going back to earth at the same way and arrive at dinner.[/B] [B]You would be 8 hours older, but on earth are 18 years past.[/B] The breakfast plates in the sink would have grown legs and taken over the kitchen as well as the house. Heinleins Time for the Stars suggested that anyone travelling by normal spacecraft means to the stars would leave a planet and the advance of technology left behind, coupled with the suggested alteration of time on the planet Earth would mean the later generations should in theory overtake the first craft with whatever advanced mechanism theyve built to travel to the distant lands. This uses the idea put forward by Einstein, but in my mind a spacecraft that is travelling at great speed but not aging, would appear to the earth observer as not travelling so fast (as Earth is gaining more years than the travelling vehicle), which somewhat conflicts with the thoughts of building a super fast craft in the first place However in the greater picture of 2Old, the speeds at which the two objects (planet and spacecraft) are moving apart, is all relative when compared to all else around them, and so the ages gained by either side would appear to be identical. Einstiens idea even though its been proven in the local vicinity of this planet, doesnt seem to hold water when going into deep space The beginning of a headache I think, unless someone can clarify [/QUOTE]
