Time Travel

#1

Well, I thought it would be great to discuss our theories of time and the movement about it.

My many theories:

#1: Time is linear, and can’t be manipulated at all.

#2: Time is multiple lines,
Line 1: “Now” Line, this is whats happening now, and it’s constantly
Changing. It’s like a universal clock, the Main time line.

   Line 2: The "old" line, it can move freely between the past           
   But never intertwines with Now or the future.   

   Line 3: The "New" line, A line that can move freely and infinitely into the 
   future, can't collide with Now or Past.

#3: Time is one line for now,
Right now it’s one line, but when a time machine is created a new line will
be formed, but it can’t travel to a period where a time machine doesn’t
exist.

I have more, but i’m too tierd to type.

There is no way to time travel. If there were a way to time travel in the sense of people going back in time in one plane of reality, we would most certainly already know about it, because someone would have inevitably at one point in time come here and either spilled the beans accidentally or on purpose. All of history would be a mess of people hopping in and out, even if all this ocoured thousands of years apart.

Dimentional travel is a totally different case however.

The only form of time travel ive seen as remotely possible involved the idea that nothing could move at the speed of light. What would happen is that if we were to travel at 99.9999999…% the speed of light, time would actually slow around us to prevent us from reaching light speed. To those experiencing this slowing of time would not be able to tell, but people observing it would see them in slow motion. Because of this, if they stayed in this state for a few weeks from their perspective, they could have actually traveled forward in time years in everyone elses’ perspective. Basically, if they boarded a train on 5/12/11, and stayed in the train for 2 months while it went 99.9999999…% the speed of light, their calenders would say 7/12/11, while all the calenders off the train would be around 7/12/88 or so. This is a rough estimate of the time btw, i’m not being exact. This means that they and everything else in the would remain their initial age plus 2 months, while the rest of the world would have advanced in normal time. This form of time travel only moves forward, but not backward.

This is assuming time is an entity or thing, and not just a verbal explination for past and future events.

I don’t know much about the subject, but I would assume traveling at the speed of light or beyond would just make you get places fast.

#5

Time is like an ocean in a storm. You may wonder who I am, and why I say this.
Sit down, and I will tell you a tale like none that you have ever heard…

#6

Time is just a measurement.

#7

Particles do exceed the speed in light in special cases.

Particles can transcend ‘time’. We’ve done it. They can go forward, but not backward.

The idea of ‘time’ itself is a human conception. There are several good books on the subject.

Khaos124 post isn’t a description of time travel, it’s an illustration of an effect of relativity. The effect he’s describing is why software in communications satellites includes programming to synch the constantly changing time differential between a satellite in orbit and the Earth. The calculations for space missions as well as software coding for all digital hardware takes this into account. It’s called the Time Dilation Effect. It effects the age of astronauts, and the longer the astronaut stays in space, the greater the difference in aging.

That’s not really ‘Time Travel’, though, because time and space don’t exist as two discreet entities, they’re one entity - timespace. ‘Time travel’ would be altering the time co-ordinate of a body without it moving through space relative to the observer. But, as I said before, this has also been done. But it doesn’t mean that you can jump into a Bathysphere-looking contraption, go backward in time, and create an investment account that accrues interest compounded into the trillions of $$$, convince your Dad to invest everything in Microsoft, bet on sports teams, or seduce your own teen-aged mother - fucking pervy wankers.

The only meaningful way to time travel would be to the past; with the time dilation effect, travel to the future is relatively simple, and breaks no physical laws. Going to the past however, is what would really matter. So far, physics as we understand it does not permit time travel to the past. Causality cannot be violated. However, there are some loopholes in that. Wormholes and closed time-like curves might possibly be used to go backwards in time, however the way they work would mean that time travelers could not travel back any farther in time than the time machine was created. Meaning, since time travelers couldn’t reach us back here, we may never know if time travel to the past is possible until the day it is created. And then there’s also the possibility of clones and such being created - if you haven’t seen it, watch the movie Primer. It’s a total mindfuck to be sure, but it’s a great depiction of one of the most plausible methods of time travel.

And yes, there is also the many worlds theory, but that would hardly qualify as time travel to the past since you are entering another universe, not traveling backwards in your own.

Even talking about time travel is banned in China!

#10

How do you know that this hasn’t happened? :wink:

EDIT: In my conjecture about time travel, I solved this problem years ago. As soon as you step back in time, you irrevocably change things. You can meet yourself in the past without danger of the creating a time paradox, the result of which could cause a chain reaction that would unravel the very fabric of the space-time continuum and destroy the entire universe! (Granted, that’s a worst-case scenario. The destruction might in fact be very localized, limited to merely our own galaxy.)

The “you” that you meet will no longer be you in the sense that it’s you. You and “you” will have the same memories and personality but as soon as you step into the past, the timeline you were in is demolished and irrevocably lost. That other “you” will react as you would react, but it wouldn’t hurt anything and wouldn’t affect you, because that “you” is now a different person than you are. You can go back and save JFK. You can go back and kill your grandfather before your father is born. All those fun “paradox” things are eliminated.

It was neat and clean and I thought that I was the only one to think this up. And then that new Star Trek movie came out. :rage:

#11

I thought that time was just composed of wibbly wobbly timey wimey stuff.

#12

Well, when it comes to time travel, we are fairly certain time can be manipulated by speed and gravity. We have observed this, and have to compensate for this in our various GPS satellites.
However, when people talk about time travel, a lot seem to be thinking about backwards time travel. I’ve got a couple ideas about backwards time travel. The first is that IF it is possible that paradoxes are avoided by not seeing time as linear. You can’t travel back through time and kill yourself before you travel back in time precisely BECAUSE you will have not have done ( that’s a weird sentence ) . I think that would make sense, because it could simply come down to something you can’t do because of the nature of our universe. You can’t create a paradox because the nature of existence prevents it.

All that being said, I don’t think backwards time travel is possible at all , because from what I have read and from what I understand of the processes that we theorize could allow for backwards time travel seem to have problems getting around the forces and laws of our universe. I think it may prove to be impossible.

That’s just me though.

#13

So you are talking about dimentional travel? Traveling not into the past but rather into an alternate plane of reality?

#14

Guys I can time travel!

I put my head down on my pillow and the next thing I knew it was 5 AM!

#15

Not really. Are you in an alternate “plane of reality” right now? Do you frequently change “planes of reality”? If you come back to this point in time right now, is that switching a “plane of reality”? You experienced this stuff and when you come back, the other “you” will experience it again…but then you arrive and change things.

#16

Even if time travel was possible either into the future or the past, it would be totally impractical. Not only would you need to invent the time machine, you would need to build a spacecraft capable of travelling vast distances of space, since over time our solar system orbits the galactic center and you would time travel into a vacuum, where Earth was when you left.

#17

I SO wish backward time travel was possible. So, I could travel back, seduce all your moms, and film the hot, noisy, animal sex.

Then when one of you cunt bastards posts something like, “Fuck you, you’re a fucking tard, and you probably listen to Justin Bieber and enjoy buttsex.” , I can post the link to the appropriate vid with the comment, “True, but I fucked your Mom, bitch !”

Nobody in this thread though. you guys are cool. Though that doesn’t mean that I wouldn’t have done your moms back in the day, given the opportunity.

#18

Those cunt bastards would probably be your sons though.

#19

Alright, I’m not understanding then. If I were to “go back in time” five minutes and shoot myself, and then return to normal time, would I be dead in normal time, or would nothing in normal time have changed?

I r confus

Time travel to the future is easy. We do it all the time.
