shbeita Posted September 12, 2008 Posted September 12, 2008 SIMPLE THINKING Changing the perception of time isn't traveling in time Let's say seven years ago a young man who was born on 11/September/1971 and on his 30th birthday was watching TV and was shocked seeing the airplanes hitting the trade center in USA "Events of 11/September/2001" & he thinks he could do something about it because he owns a flying machine which can approach a speed double the speed of light... He decided to travel in time trying to change what happened He puts a clock on top of TV set & synchronizes it with the watch on his hand & took the flying machine "which travels at speed double the speed of light" & starts to fly away just a moment after the airplane hitting the Trade Center...he left with the speed of light looking behind he sees the clock showing the same time as if it stopped & frozen moment of the impact as if TV was paused then he speeds up & starts to see the clock going backward & the fire becoming less & less the airplane itself flying in the opposite direction away from the building tail first...& he travels tell a moment preceding the impact by hours then he started to travel slower : First at the speed of light when he noticed "seeing" that the clock stopped again & what is shown on his TV screen at home stopped "paused" His speed becomes less & less tell he stopped & he realized "is seeing" that the clock on TV is running at the same speed as his watch & the TV showing the same TV programs he watched hours ago... He is feeling bad about it started to think the airplanes will hit the same way & something tells him to come back & try to change what happened by informing the Good Guys about it So they Can take the appropriate measures & prevent these events "airplanes hitting the trade center" from taking place...! So he started traveling back at the speed of light but he noticed "is seeing" that clock on the TV is running double the speed of his own watch & more... all that happened is happening with doubled Speed & by the time he is home he discovered that actually he didn't travel in time but his feeling of time '' visual perception " was deceived ...He is feeling bad about two things that he couldn't change the events & that his flying machine which travel so fast couldn't actually travel in time...Because simply by... Flying away: At half the speed of light makes time seems slowing down At the speed of light time seems to stop At double the speed of light time is going back "reversed " When stopping the same speed as it was before "Normal...but in the past" Flying or Coming back: At half the speed of light then light speed then double light speed it looks That time is speeding up & events too & when he is at the starting point (home) he is back to the Real time & his watch & the clock are showing the same time... Which means this was visual (eye} perception of time which was deceived... And for doing so for the auditory perception "hearing sounds of events” slower machines but which travels faster than the speed of sound... J.

swansont Posted September 12, 2008 Posted September 12, 2008 he owns a flying machine which can approach a speed double the speed of light... Once you postulate something that violates physical law, you can justify pretty much any answer you want to.
Pete Posted September 14, 2008 Posted September 14, 2008 A particle going twice the speed of light (i.e. a tachyon) would not violate special relativity (SR). However it does seem to violate SR for something like tachyonic matter (non-particles like a spaceship). How would one transform to such a frame? If they did then objects in that frame would be at rest violating the assumption of tachyonic matter. For that reason I agree with swansont. re - At double the speed of light time is going back "reversed " - I don't see where this came from. Its not a meaninful statement in SR. At least if you can't have tachyonic clocks. It'd be a strange thing if they existed. If you have a tachyonic particle which decayed in its own frame of reference then it would appear to "un"decay from other frames. Totally wacky stuff.
I_Pwn_Crackpots Posted September 16, 2008 Posted September 16, 2008 But humans and time machines are not tachyons, so they would violate special relativity. Since the hypothesis of the OP is false, you can come to any conclusion you want.
caveman42 Posted September 16, 2008 Posted September 16, 2008 I dont think scientists around the world dont even consider funding for TIME TRAVEL analysis. Its just impossible. Unless some wormhole is created by the HADRON COLLIDER, then thats a different story.
I_Pwn_Crackpots Posted September 16, 2008 Posted September 16, 2008 Its just impossible. It's not strictly impossible per se, but the OP's proposed method certainly is.
Pete Posted September 17, 2008 Posted September 17, 2008 (edited) I dont think scientists around the world dont even consider funding for TIME TRAVEL analysis. Its just impossible. Unless some wormhole is created by the HADRON COLLIDER, then thats a different story. I disagree. E.g. Time Travel, Deser and Jackiw, Nucl.Part.Phys. 20 (1992) 337 http://arxiv.org/abs/hep-th/9206094 Notice the part where it says This work is supported in part by funds provided by the National Science Foundation under grant #PHY-88-04561 (SD) and the U.

YT2095 Posted November 10, 2008 Posted November 10, 2008 Time travel has many Paradoxes Really, how so? I don`t think it presents Any.
Flashman Posted November 10, 2008 Posted November 10, 2008 Yeah I moved forward 2 minutes while scanning this post and didn't kill my grandfather or anything.
big314mp Posted November 11, 2008 Posted November 11, 2008 Yeah I moved forward 2 minutes while scanning this post and didn't kill my grandfather or anything. Clearly, you created an alternate time stream, in which you did kill your grandfather. You merely inhabit the one in which you didn't Disprove that!
TheDonner Posted November 17, 2008 Posted November 17, 2008 my physics professor told us that in order to have time travel we would need Antigravity, but since we dont have Antigravity that is "Problematic"
midgetwars Posted November 25, 2008 Posted November 25, 2008 When you exceed the light speed don't you go into the FUTURE not the PAST???? If I'm wrong tell me. ALSO if you go into the future, WHAT IS THERE????????
Klaynos Posted November 25, 2008 Posted November 25, 2008 We're all moving into the future. You can't exceed the speed of light, as to do so you have to pass thew the speed of light.
freegoldrunner Posted November 26, 2008 Posted November 26, 2008 Time Travel is PRACTICALLY impossible. How can you go in the past????? What's in the future??? The future isn't written.
Sayonara Posted November 26, 2008 Posted November 26, 2008 The future isn't written. Being unwritten is not the same as being indeterminate.
north Posted December 15, 2008 Posted December 15, 2008 hmm in order to time-travel means that you would have to back-ward the total expanse of the Universe , actions not just a locale
Sedit Posted December 15, 2008 Posted December 15, 2008 imagin what it would look like if you traveld in a small circle faster then light you would start to stare at the back of your head... weird
north Posted December 15, 2008 Posted December 15, 2008 imagin what it would look like if you traveld in a small circle faster then light you would start to stare at the back of your head... weird imagine this is all there is though nothing in real terms however
Sedit Posted December 15, 2008 Posted December 15, 2008 I think the basic principal of backwards time was summed up in the post right befor my last one. In order to 'go back in time one would have to change there position in space/time look at it like this north If a clock on you and one on earth was reading exactly 12:00 when you left going twice the speed of light. You look at your clock and at exactly 1 hour into the flight you lookback to see the clock still on earth. where your clock reads 1:00 stating that an hour has past the one on earth is reading 11:00 stating that an hour was lost.. This is because since you out ran the light that was precently being given off from the clock on earth at 2x its speed you are now seeing the light from the clock from 1 befor you started your journey. If you went the speed of light the clock on earth would still read 12:00
