Lets say that hypothetically speaking time travel was real. I'm wondering, what is the pits idea on time in general, or time travel? The way I look at it is if time travel were to ever exist we would know by now because something would have happened, unless it were kept a secret so I don't know.


What do you guys think? Time is linear or spacial or maybe based on different sets of planes depending on the actions one would take? Time travel possible?

tl;dr

Discuss time and time travel.
I havn't changed this thing in a year.

Watch some stephen hawkin into the universe. He says it is technically possible to travel forward in time but not backards. when next to something with a high mass, the time goes slower then things not close to the mass. I can't explain it too well but watch it. it is quite good.

Stephen Hawking thinks it is possible, therefore I think it is possible. He's my hero.

Time isn't a dimension, it is just a way that we measure events by comparing them to predictable events, such as the Earth's rotation as a day. The only way I think time can appear to be altered is if you adjust your brain's speed of perception.

Actually, Stephen Colbert said that Stephen Hawking said that you could possibly go back in time. Hawking said he would visit Marilyn Monroe and Galileo.

Lol, he would go back and tap Marilyn, then go back further to brag about it to his science buddy. But he wouldn't stop Hitler, or save Jesus, lol.

Time was explained to me like this. We see time as a line, aka "Chronos" time.

God sees time as like a giant bubble due to existing outside of time. He sees creation, now, the end, and everything between all at once. This is called "Kairos" time.

(Also, I know those probably aren't spelled right.)

If time travel were possible and something happened that drastically changed things, I don't think we would know because it would be normal for us. It's not like we would believe someone who said they were from the future.


As far as travel goes, I think your influence would happen 2 ways.

In this instance, a traveler comes back, influences time so that in the next timeline, he doesn't go back in time, so then in the timeline after that, he goes back and influences it so he doesn't go back, basically making the pattern I just made above, the horizontal lines being time lines and the back slashes being the travel from one line to another line, earlier on.

In the instance above, the traveler goes back and influences time in a way that the traveler of that timeline goes to the next timeline to influence it, basically just repeating over and over with each traveler going back and influencing him or herself to travel back in time.

That's just my hypothesis though.

EDIT: Well crap, apparently my visual representation isn't pulling up right.

Check out Ronald L. Mallett. he is a professor at UConn, he claims time travel is possible using highly focused lasers but he thinks a time machine could only send you back to the date the machine was first switched on. interesting stuff

Time travel is possible in the sense of Albert Einstein's Theory of Relativity.

For example: Let's say you're traveling out in space at a speed of 0.9c for 75 years on a round trip to and back to Earth, all in your frame of reference. Now, to you, it's only been 75 years, but when you have returned to Earth, it would be 172 years after you left, thus you traveled 97 years into the future.

Depends on your definition of possible. It's possible if you can locate an early 80s DeLorean, find a set of flux capacitors for it, and hire Chistopher Lloyd to navigate for you.

Everyone knows that it's possible to "travel forward in time" due to the theory of relativity (even though that's actually making time slow down for you while remaining constant for everyone else). Traveling "back in time" is where it gets sticky, due to paradoxes and such. I contend that it is impossible for both free will and the possibility of traveling back in time to exist, since if people had free will and at any point in the future discover the ability to travel back in time, the universe as we know it could be destroyed. Since, if one subscribes to the idea that time travel is possible it is sometimes easier to view all of time as simultaneous (a la Tralfamadorians), one could think of this paradox as 'having occurred already' unless said time travelers had never made it this far back in history, which seems unlikely.

However, if one contends that free will does not exist, which much of the evidence does seem to support, then there is the possibility of the universe 'not allowing' these paradoxes, thus allowing for the possibility of time travel. However, since as of yet the existence of time travelers has never been documented, one of two possibilities must then be true: Either these time travelers have been extremely careful (a definite possibility, because if they did exist they surely would be mindful of the 'butterfly effect', meaning any small action by them could drastically alter human history, though as mentioned before the universe might not 'allow for this'), or, as many scientists believe, the means for receiving time travelers must be built before such traveling is able to occur. Once we build the destination, some hold, many time travelers will begin to appear.

Ok this isn't going to be something you would expect to hear from the pit.This is going to be an intelligent converstaion.

Personally i think of time as a two or three planes which are very close together. These planes vary apon the others so much so that they are always connected.

For illistrative purposes go to your bathroom and get a piece of TP. presuming it is two ply, take one square and wave it. Notice that the two plies stay together. this is how i believe time works.

Now Time travel is a different subject.
Ok, now think of that piece of toilet paper as a waving time line. We as normal humans are along for the ride, going up and down as we go. If we could find a way to just stay in the middle we could speed up time,or time travel. well lets say that a strong electromagnetic shock would allow us to travel this medium, theoretically if we were to use an anti-electromagnetic shock we should be able to go backwards. As long as we canfind a way to go forwards we should be able to go backwards.

These are my beliefs and theories on time and the traveling of time. This may be possible theories of my imagination combined with a slight sleep deprivation or completely true. In hindsight these ar possible theories very advanced for a 16 year old boy who loves to play his drum and guitar.

time is an ocean and we are boats in motion; as we move we make and leave ripples behind. Time is and always will be present.


Then again, what is time travel? I leave earth at the 99% the speed of light, come back 100 years later relative to me, and everything I knew has changed entirely. Hundreds of years have gone by, and I have aged little, though I am able to see my great great great great great great great great great great great great great great great grandson, and he's older than I. is that time travel? Did I really travel to the future?

You actually come back aged 100 years since, to you, you were gone for 100 years. While you were traveling, the Earth aged 709 years. So, you "traveled" 609 years into the future.

I think of time as a 4th dimension like this:
assume u are in a city where the street system is set up in a perfect grid, where the streets are numbered. Odds run east and west and evens run north and south. You receive an invitation with the meeting place at the building on the corner of 4th and 9th on the 3rd story (x,y,z dimensions). However, with just this info you might miss the meeting. You need a meeting time in order to make your appointment. Hence, time is the 4th dimension. I'm pretty sure i took that example from hawking's into the universe but its been a while since high school physics class.

I understand your logic, but think about it this way: how do you determine what time it occurs once you are given a time? All you are given is a number which essentially represents when the appointment would occur compared to the predictable events of the earth's rotation on its axis and around the sun.

I believe that it is possible to travel back to a said time with the ability to change all forms of future outcomes, the only problem is that the universe that you have now changed has duplicated from its original form, hence, creating an alternate universe based upon your manipulation.
