I have a few problems. Now to say my personal theory, I believe it is possible to travel back in time if you move beyond light speed. Looking back in time is certainly possible, and we can see great examples looking at the sun. You see the sun that was 8 minutes ago. If we take all time as being the same all over universe, we see the sun 8 minutes ago, and it is now what we will see in 8 minutes.

Now my problem, that no science fiction fan ever could explain me without saying destiny: The past is saved information. It is saved in the light and sound and whatever emitted. Now the FUTURE is something else. Because the future has never existed! Hence, in my believes, the future is only something we can try to determine/guess.

If you don't believe in destiny, the future is simply non existing. At least not if i take time being the same all over universe (Now is now, but looking from a place distant, the now is delayed). If time is not the same, future is still not existing. The NOW is emitted, not the future. The emitted things are collectable. But the future does not exist


So science fiction "diciples", please correct me. Last time i discussed this (in real life) with one he nearly HIT me because he couldnt think of the future not being existant yet. But yet he didnt believe in destiny either!


P.s: I do realize that travelling faster than lightspeed is not existant. There are a few theories of some quants which could transfer information between particles faster, but i am not too sure on this subject. No matter what this is not the topic!

Just my small thoughts. Sorry if I seem stupid having them Just something I think about when I feel like it. Like purpose of life (so far i have come to that we decide the purpose ourself. Be it love, money or something completely different, its up to the individual. There is no general purpose)

Right. But your example has some flaws.

Talking about astronomy, you can predict the future.

What im trying to say is that about physic fenomens, past and future is predictable or "saved information" because you can use maths to move to past or future.

BUT in our lifes that dosent happends. You cant go back and you cant go to the future, because none of them exists at this moment.

Now the FUTURE is something else.

It is indeed. It's like driving your car along a curving road enjoying the scenery,
only you know that whats in front of you around the next bend already exists.

But TIME is different. If what's coming to you in the next second doesn't exist NOW,
it means the world is created right in front of your nose (out of nothing?) as time
ticks on, and that's really weird.

Even weirder is the fact that if this isn't true, then future and past exists now,
only you can experience it in a linear fashion. But if future exists now, what about
free will ???

Arghh, I have these kind of thoughts myself and when I find an explanation, I'll
post it here first.

I see destiny like this:

i. I'll only ever have one life and whatever choices I make at any particular time I can never go back and re-make.

ii. This means that out of however many possible actions I could take, I'll only ever take one set of them and no matter what I choose to do I can never deviate from this fact.

iii. So, this means my life is on a set course however I still have controll over that direction.

Hopefully that makes sense. It's probally best to explain it by thinking about looking back on your last from the point you presently stand at.

Read "Dinosaur Beach" by Keith Laumer and you'll hope that time travel is an impossibility!

> it is possible to travel back in time if you move beyond light speed

Why do people think travelling faster than light will somehow "move time"?
All it does is mean you're travelling very fast -- there's no evidence to show
that it alters time, or that time itself depends on speed of some sort.

According to Carl Sagan and other scientist (Albert Einstein per example), if you travel at speed of light, times 'moves' slower.

The idea to move to the past has nothing to do with that and its like SciFi.

Mmmm...

We are animals and we have some biologic pourposes.

Yes, i know, many people can argue against that. But its a starting point if you want to find some "general" point.

-------

As animals we want to:

-Keep ourselves alive
-Reproduce
-Make our descendents as succesfull as possible

Look at the moral of almost every culture and in some way try to achieve that.

Maybe there are some additional meanings of life... i don't know. But the biologic meanings are the ones i describe before. That are general.

the time-factor is connected to the speed and to the mass.

an object with mass can not travel with lightspeed, the closer it comes to it,
the heavier it becomes and the slower time flows.
if it theoretically reaches lightspeed, it's timeflow will be zero and it's mass will reach infinity.

things that travel with lightspeed e.g. photons don't have a mass and don't age.

things travaling faster than light are not classic materia because they have negative mass, and yes, they travel backwards in time.

by this means, past and future are existant, but free will still exist,
because decision or possibility is another dimension orthogonal to time.

the immediate information-transfer is some different thing, it could be done with particels that are connected by some yet unknown function like they are two sites of the same single thing. it is not really anything moving faster than light, but some change applied to the same thing that appears as two spacely devided things.

....still, there are more miracles than answers...

Rubbish. And they've proved this how? What have they invented that moves
faster than the speed of light? Exactly. It's just talk with no empirical proof.

But let's say a vehicle is invented that moves twice the speed of light. If I get
in it, and travel in it for a year, I won't have aged a year? Yeah, right.

Besides, once something is done (a burnt match) you can't "go back" and
return that match to an unburnt state.

Time is a man-made unit of measure; it's not a physical thing that can be
traversed like one travels a road. The whole time-travel issue is based on
the premise that it is a physical item, when it isn't.

>> if you travel at speed of light, times 'moves' slower

> Rubbish. And they've proved this how?

was a misunderstanding.
travelling with lightspeed would stop time.
reaching near to lightspeed slows down time, and this have been experimentally proven.

this is something more, this concernes enthropy....

My personal theory is that if you don't rotate your hamster crop often enough, some of them go off and you never get to shave them ever again.

The speed of light is just the speed of light. In an infinite universe infinity is the maximum speed of anything. Certainly 1 micron faster than the speed of light is not the speed of infinity...

Our problem is, at the lower levels of math and science, the number 0 is considered to actually exist. It does not really. 0 is a polit fiction invented to keep order in our preverted senses.

Number lines that look like:
4 _ 3 _ 2 _ 1 _ 0 _ -1 _ -2 _ -3 _ -4

Are completely false in an infinite number set.

There is no way to reach 0.

In fact that number line should read:
4_3_2_1_-1_-2_-3_-4

Faster than light is the square root of -1.

You have passed inifinity and come all the way back around to negative. Then you climb the negative scale.

Oh and the speed of light varies on conditions in the surrounding space.

I actually have two theories about this:
1. That it's possible
2. That it's not possible

Both could be true, but I have no way of knowing yet since our understanding of the world is far from complete (and as humans we might never be capable of understanding it). Even our top scientist doesn't need to have a clue at all. Because it's like we're inside a game and we found out that polygons is our smallest building blocks. And then we think that's how it works, but we didn't see all the programming code that controls the polygons.

But let's say it's not possible, then our world is like a frame in a movie, which always changes but all the previous or future frames is nonexistent. And if you were to travel in time then you would have to change all those pixels into their previous or future state but you can't since the is no other frames.

And if it is possible then there is both previous and future frames, but when we travel in time we doesn't change the current frame into the others, but we move ourself into the other frames.

Mathematically speaking, it IS possible to travel in time. As far as I can remember, a very prolific mathematician said that the only geometrical form that can achieve this (transposing to another point in the past) is the cylinder. He demonstrated that if a cylinder spins at a speed higher than the light speed there is allways a point near it where time travel is possible. However, as we are not living in a world 'ruled by maths' and everything is relative and in perpetual change, I'd say this kind of time-travel models are simply not practical.

About the speed of light... If the Universe IS infinite and speed of light exists => there must be a speed greater than it which results in the fact that the speed of light can be considered the smallest in the Universe hehe.

We are trying to understand things that are beyond our 'processing power'. If only I could stop some parts of my brain and make other work faster .
