Hi, Just say if a star was about to explode, and if one had the technology to get away from it instantly, lets just say something beyond light travel say a wormhole. Just say they were there just before the explosion took place say 10 secs beforehand. Now suddenly theyre about 100 light years away. They wait 5 minutes or so and go back to the star remnant, Now the question i ask is that because they have instantaneous travel how much time difference would have taken place at the star in the 5 minutes they were gone. Or is it as simple as 5 min. Or 200 years. <div class="Discussion_UserSignature"> <p><em><u>SPONGE</u></em></p> </div>

Instantaneous travel violates Relativity. If we ignore relativity, then there is no time dilation. It would be merely 5 minutes. Instant travel, FTL travel and wormhole travel are 3 different things. <div class="Discussion_UserSignature"> <div> </div><br /><div><span style="color:#0000ff" class="Apple-style-span">"If something's hard to do, then it's not worth doing." - Homer Simpson</span></div> </div>

Ok then to simplify it we will say wormhole travel how does that sound. <br /><br /><font color="purple">After months of want and hunger, we suddenly found ourselves able to have meals fit for the gods, and with appetites the gods might have envied. <br /></font> <div class="Discussion_UserSignature"> <p><em><u>SPONGE</u></em></p> </div>

If you are traveling through the wormhole and returned at non-relatavistic speeds it would still only be 5 minutes. Now, if the destination end of the wormhole is accelerating at or near the speed of light, then you would experience time dilation and return after 5 minutes only to see your star (depending on it's size) in it's future state as a neutron star or a black hole. It's all about how fast you are traveling relative to the observer. Just because you travel through a wormhole doesn't mean you are traveling fast... it's a mere shortcut. <div class="Discussion_UserSignature"> <div> </div><br /><div><span style="color:#0000ff" class="Apple-style-span">"If something's hard to do, then it's not worth doing." - Homer Simpson</span></div> </div>

Yes i understand this, its like the ol saying f we could move away at the speed of light way form the earth say to the nearest star and return again we would only experience 8 yrs while the time time on earth would have past considerably more. Who is to say that a worm hole is non relatavistic, if im suddenly 100 lightyears away in 5 mins or get there instantaneous and wait 5 mins what is the difference when i return again using the two methods. (derekmcd just take it as a hyperthetical, im well aware that matter cannot go the speed of light and that it mass increases the faster you go and im aware of stars becoming neutron stars or blackholes by their mass im just trying to get ideas and possibilties) as for wormholes their structure and behavior is still in the imagination. <br /> <div class="Discussion_UserSignature"> <p><em><u>SPONGE</u></em></p> </div>
