General Chat / Why Time TRAVEL isn't possible.

I was skimming through Timeline(book),and there was a part where some ITC head-case was talking about why Time Travel isn't possible for all eternity.

Read on.


Some people think that time moves with us and with everything else in the world. If that was true,that means that the present,past,and future are places,like us. Since it's been tested many times,the past,present,and future aren't locations. They aren't two different places like New York and Paris. You can't travel to them. And in that case,you can't change the past,it's hard-coded into history. And since the future hasn't happened yet,you can't go there. Period.

Then again,you can make a time machine out of a wormhole. I won't go into details,though.


Confusing? Oh,well. I went as clear as possible. No arguing,please!

Welcome to Qunatum Physics Theory of the 1960s

So it's theoretically possible that alternate universes exist, cool, great, how do we get there?
How do we control which one we are going to?
How do we get back?
How do we prove it?
Who is actually spending their brain power on this, and not on something that could actually come to fruition and help us in the next 200 or 300 years?

Have you not been on the Tower Of Terror!? :-o

Apparently there are something like 20-odd "dimensions,"...

I get confused with anything in Physics that starts to get messy. I get everything except wave-particle duality (I can explain it for exams and stuff, but I can't really understand it) and all the quantum pjysics stuff..

Add in discussions about string theory, etc and you'll see why physics was never my favorite subject.

A dimesion is a way to describe something mathematically. You can describe time mathematically.

If you were to describe an object in space. It will be 5 ft long, 4 feet wide and three feet high in two minutes. Other things such as spin, energy, charge, density, can all also be mathematically represented as dimensions. Time is not a spacial dimension though, there are sonly three on those, if thats what you are thinking, which you probably are.

While on the subject of fourth dimension travel, I suggest reading "A Wrinkle in Time" which plays on the theory in an intriguing manner.

No, I wasn't really thinking of anything lol.. I don't really get any of it *at all* like I said, so I was just passing along my confusion about all these dimensions

Andrew, what makes you so sure there are only 3 spacial dimensions? You know, we can actually see 4 dimensions unravelled, in the form of a tesseract. The human brain is just not equiped to invisage this net folded into the next dimension. No-one has proved it doesn't exist.

I still stick to my argument that you can't go back in time, because if you did you'd just do exactly the same things that you did do before, as dictated by the various impossiblity arguments in this thread. And what time scale would you move around in time anyway?

That assumed time is a straight unwavering line that you go forward or back on. I see time like a tree, it is static there is no flow, we just movie farther and farther out on it's infinitely long branches.

Think of it this way. When you wake up in the morning, and you have a choice as to whether or not to brush your teeth, at this point you are at a fork in the space-time tree, on one end you brush your teethm on the other, you skip it. Both universes exist, but are offset by some theoritical 4th dimesion that our brains cannot pick up on.

So the theory exists that there is a universe for every possible combination of events and times that could ever, have ever and will ever take place in the "multiverse", and that time travel would not be traveling through time, but jumping from universe to universe, that each exist in seperate times and continuing your journey from there. Like climbing on branch on a tree and then leaping to another and climbing from there.

I meant that current physics and math accepts three spatial dimensions, theories aside, not that that could be proven wrong, which I'm sure it will eventually.

Time travel is possible... in your dreams!

Twimasta is probably my least favorite member.

He's stupid, not funny, and probably fat and ugly.

Therefore time is the fourth dimension

wait does that mean that x is a timecoastar lol

you forgot 'cool', mister

Outlaw, i think that your a lil cunt face bitch.

I've tried over the past 6 months to start a site based on discussion and debates such as, Math, Physics, Space, Philosophy, Literature etc, but I've never been able to get a large enough community to join...

Would anyone be interested in a site for discussion like this?

Website

Like that didn't take long enough...

Anyways, the site looks pretty good imo, not the best, not the worst. The forums have a few bugs, I cant fix them, hopefully someone else can.

Also, I couldn't think of a name, so thus, there is no name for the site right now...so let me know if you have any ideas.

Hopefully the community at this site will grow....

Thanks,
MM

is this still up for discussion here? well if so...

first of all, about time being the fourth dimension, it is. mystery mod explained it well in a short way but i'll just add something:

0th - A Point in space
1st - A line extending in two opposite directions
2nd - A flat square
3rd - A Cube
4th - Time

each object, if its a point, a line, or square, or a cube, is placed at a certain spot. it will always stay in that same exact spot untill it is moved. when it is in the 1st, 2nd, or 3rd dimension, it will never move because movement needs time. if time doesnt exist, everything stays still, therefor, in order for the specific object to move, it need another dimension, which is time.

on to time travel, this is what i believe; i dont think we will ever time travel in the standards we speak of. we will never be able to put our bodies into a differant time. the most we will be able to time travel is seeing the past. when you look at the sun, what you are really seeing is the sun, 6 minutes into the past. when you look at the farthest visible star in the sky, you are really seeing (i think) around 1 billion years into the past. i saw on a show on the discovery channel that the hubble telescope that was put into space, was powerful enough to almost see the creation of the universe.

i dont think any of the parallel universe stuff exists. it just doesnt seem logical.

I think that time travel is a waste of time.
It obvious that it isn't going to happen because someone would have come from the future and been like
"OMG WSUP IM HACKERS FROM FUTURE MOTHER RUSSIA RULES ALL, KK."

That would make sense. Never rule anything out though.

How do we know that people in the future aren't using it to travel back to the past now? Pretty whacked out idea, but entirely possible.

I've already explained this. You can't travel into the past because there would be no life force behind matter.
Yeah, you may be able to rearrange matter, but everything would just keel over.
