Please give me your definition of time; what you perceive time to be, the implications of this perception, and whether or not you believe time travel could be achieved. Thanks,

Time is an axis defined on creation by UNKNOWN
I don't think time travel is possible for us because it was not meant for us to hold that power simply because we could not carry the responsibility

think time is a couple things related but lumped
our perception of motion
of a useful side effect from a source

the useful part to me is it works as a recording device
what it's a side effect of not sure... maybe am thinking wrong, but what is "width" a side effect of?
the source could be debateable till "kingdom come"

on time travel I think it can viewed/observed, not sure if interacted with after it's been recorded. fun to think about tho in both cases.

Edit: maybe not "side" effect, but like "8th" effect or something. Think gravity is a "side" effect too, a result of smaller motion corkscrew maybe.

I've always felt that time was our understanding of our existence in the fourth dimension. Time itself is composed of the sum states of every object during its existence, and our view of time is basically a linear slide show of those states. Were we able to step back and see the whole of this dimension, objects would consist of their normal 3 dimensions, but would also be that object in every instant of its existence, all at once. It's kind of tough to get a picture of it in your head, but it leads to interesting ideas as far as time travel goes. Basically that once you've stepped back and were able to view time in it's entirety, it would be a simple matter of chosing where to step back into it to arrive in a different time.

'ticking away, the hours that make up a dull day'

My thoughts on time is that it really doesn't exist, it is just a measurement that was calculated into units that fit in with the rotation of the Earth and the seasons. Animals don't know what time it is, they just use an inbuilt sense and know it's 'time' to do something due to the Moon, seasons in relation to whatever it is they are doing. Time is a cycle, just like a woman's 'time of the month', it occurs because of a cycle inside us, so if I were to define time at all, I would say time is a cycle, just like the cycle of the seasons or the cycle of the Earth's rotation.
The implications of this perception would be that time will go on forever regardless of whether humans are here or not, it always has been and always will be.

Time travel is theroetically possible, there is nothing in the laws of physics to prevent time travel, it's just doing it that's the hard bit.........black holes are the key to time travel according to Einstein's theory of relativity.

I think the most damning lack of evidence for time travel is the fact that we have not had any visitors come back from the future.

If you could go to the future, would you come back? I believe it's definatly possible to travel time, all you need to do is just go near the speed of light... Since time is relative a person going as fast as light theroretically wouldn't age compared to the person sitting on the couch on Earth, so that person traveling really fast would be in the future (aging slower) than the one on Earth. That's a really simple way of thinking of how to do it, there's plenty of books on Enstein's theory that make it much easier to comprehend, picture books that is.

I understand (in layman's terms!) Einstein's theories on the subject. Whether these theories can ever be put into practice is a whole different matter...

If we can make a laser, maybe we can make something to go as fast as that laser...

Einstein's theory's are just a logical way to explain the very things he was researching, that doesn't mean there isn't other ways to approach things or new ways to look at the same theory that he was researching in the first place. right or wrong, what if they are all right. the laws of imagination may have been overlooked. if you can imagine something, who's to say it can't be done. now time, i agree that time is a reference for us and for something to always have been, time can't be an issue. we need to look beyond time. even if you could go forward or back would you even change anything, if you did, you might not exist anyhow lol. maybe we choose to live by these laws. if we didn't, everyone would be the same, never learning anything new. anyhow, these are just some random thoughts i had lol.

also, not everything can be solved with math, you have to think above and beyond because there are certain rules that you have to follow in order for math to work, those rules prevent a lot, if not more than it solves.

I think that those rules cannot be broken. Nothing breaks the laws of physics.

good point, that statement proves the point i made above, if you can't think beyond those rules, then why bother to try and solve any problem that has already been solved. people would never have second guessed Einstein and just called them facts instead of theory's. a big one, is there anything faster than the speed of light? i say yes, thought is faster. with light, you have space and time, with thought you have instant. but this is just how i look at it.

But how'd you travel on a thought?

(Cue Astral projectionists and OBE people...)

i mean that there is more than we know or can explain with science in general, otherwise why would we keep working on new things. with the unknown, there is more questions then answers, at least that's what i think. with the infinite, there is always something bigger or smaller, the way to test it is to be able to measure it. just like hubble, they made it view deeper than ever before and found more than they ever thought possible, with that alone baffles the mind. i just don't think we aren't even scratching the surface, that's what makes everything so interesting.

true, in order to invent (ideas and anything) you need to think outside the box, take a look into the deep end and see what pops out. BTW a good movie if your intrested into this time thing is "Cube 2" you should see "Cube" also, but the sequal deals explicitly with time and the headaches it can create. Really a great movie imo.

i have all the cube movies lol, i find the dimensional concept they cover very interesting. if you really follow Einstein then you would no that he talks about multi dimensions.

Time is the universal constant. It is the property of nature
which prevents two objects from occupying the same space.
It can probably be seen and measured only in the smallest
of all places where chaos reigns and the laws of physics ap-
pear to break down. At this size nothing can truly be meas-
ured since, as Heisenburg showed, the act of measuring af-
fects what is being measured. Were you able to measure time
you'd find that it was related to mass and energy.

A man is a fool to rail against time and tide yet he has no oth-
er options and few other things to really fight.

Time don't fly, it bounds and leaps.

Time is a peculiar thing, the Earth rotates, creating days. The Earth spins around the sun, creating years. Therefore on a physical level time exists.

When it comes to matters of the mind however, it all gets a bit hazy. How many people for instance, wake up in the morning and the first thing they do is to look at the clock? Speaking on a personal level, I do this to see what the bloody time is, to see if I am late or early or have awoken on time. In fact, if I didn't have a clock I wouldn't have a clue what was going on lol. Many people are awful timekeepers, without our faithful clocks and watches, appointments would probably become non-existent with people being left in the lurch, stood-up and who knows what else.

One of the most fascinating things I heard was from a man speaking on TV many years ago, whereby somebody asked him why time appeared to go slower for some people than others. His answer was like this:

"If you take say a small boy who asks his parents in January for a bike. The answer from them is that he would have to wait until Christmas - 11 months away. The parent's time until Christmas would whizz by, whereas for the kid it would drag. The reason is because to the boy, it is taking up 95% of his thoughts, whereas to his parents, it is perhaps 5% - if that". This to me, made sense and it probably applies to those people who have interesting jobs and the time flies, whereas to people in mundane positions, who are bored out of their skulls, it drags like crazy.

I could not see humans being able to time travel purposely. If it were possible to say, travel back in time, they would probably try to change history - imagine the mess! Likewise, if it were possible for them to travel into the future, they would, in turn, travel back to their own time and quite likely try to prevent all and sundry - again, imagine what mayhem this could cause. The temptation would be too much I suspect.

one idea that i saw on a program on educated earth, is that space itself can be bent, allowing you to travel great distances by just folding the plane and emerging on the other side. like if you were to draw a line across a piece of paper, how to get from one point to the other, fold the paper and stick the pencil through the starting point through both sides of the paper, passing from start straight to finish. if you don't think it could be done, then how can it not be done. lol

the suns gravity bends space, that's talked about with string theory, i think.

but here's some information on folding space

http://en.wikipedia.org/wiki/Holtzman_effect

another thought, what if time travel is possible but you end up in another random dimension, then no one here would even know and the past would still stay the past.

That's an interesting concept

It would definitely stop a paradox from destroying the future because the past had been tampered with.

My head hurts now

i for one think that anything is possible, if you can imagine it. what do you think faith is, something to believe in. if we were to show out technology to someone 50 years ago, they'd think we were aliens, so how is it so hard for people to open their minds to the possibilities of the unknown.

That's a good mentallity to start with, since it's true, but getting that imagined idea into the real world is always the hardest part.

not really, most of the greatest designs or ideas, were because of something totally unrelated to the original idea in the first place lol. it's only a matter of time, once the material or compound is found, something new will emerge. that's the problem with today's science and technology, we base everything around a theory. when new theory's are found then we make another step forward. isn't that what learning and changing is all about. just like little kids, they know nothing, by the time they grow up they know even less lol. it might sound funny, but the more we learn, the more questions that we have. or at least we should have, question everything.

"Time is the universe's way of stopping everything happening at once"

Another good anonymous quote about eternity is

"Imagine a fly alighting on a stainless steel ball the size of the earth once every million years.By the time the ball is worn out by friction,eternity would not yet have begun".

As for my views,I've no idea what time is.
Cheers Karl

I'm a little hesitant to accept that time exists. The flow and speed of time is all a matter of perception. What we humans experience as an hour, would be viewed as over 2 hours for a fly just because they can see so much faster.

What do you think Ziggy?

If you didnt age and didnt need to eat and you went to a barren planet that did not rotate and had no sun, time would not exist because there is no perceivible way of perceiving time......... I think?????

Spot on observation in my opinion

If I lived as you have described, I wouldn't have a clue what time it was or anything. IMO the only thing that keeps us in the knowledge of time is clocks and watches and the Earth rotating and moving around the sun.

I mean, I don't know about anybody else, but I have absolutely no concept of time in my mind, it is only by looking at the clock that I can keep track of it.

Good example, the last time I looked at the clock it was 6.30pm. In my mind, it is still 6.30pm however.....

I am now looking at the clock and ten minutes have passed, therefore 6.40pm will remain in my mind until I look again. Hard to explain, but let's just say, I need my clock

There is the measurement of time, what is commonly perceived as 'time' by us - hours, days, years etc. This is a subjective construct and has no relevance for the universe past our ordering of it according to our measurement of time.

Then there is time as change. Whenever something happens, that is time. We might still measure this but the change exists outside of our measurement of it so this time is objective. It has no subjective measure, it is simply change. The only measurement we could make of this is to note the information of how the change has affected the thing changed.

Time travel: In my opinion it could be possible in the future direction. However I do not see it as being possible in the past direction as the information about the past has gone. To revert to some past time we would need to reassemble all the information of what the entire universe was like at that moment - an impossibility in my opinion. There are theorised to be such things as closed loops in time, allowing travel to the past. However these loops are likely to be closed in space as well as time so you would effectively be travelling to a 'room' in the universe with no exit, or perhaps even a 'micro-universe' completely distinct from the one you travelled from.

Time is a concept in the mind. We created it to measure change. And yes we can go back in time.

I think to us humans time is a measurement of change. The changes around us result in us perceiving time. If you went into sonsory deprevation chamber time would fly. This is however not all time is for it cannot account for that distinct feeling that one thing happened before another. There is definitely not any real time in the universe and it is all in our perception.

Time travel could be possible going forward. Backward I doubt. Although new theories about bending time and space could allow this. It might be that by going back you are actually entering a alternate universe just like your own just at a different time. As it seems plausible to me that all time is now and there is really no past or future.

Any comment would be appreciated.

one, take away all light, what do you have?

two, going forward or backward, if you leave from now to go into the future, you will not be in that future you went to look for because you left. going back to change the past, if it was possible, you would have created an alternate future because again, you left. so not only would you change the past you would have already changed the future.

three, if there is no time and just the now, what future or past would you have gone to?

Time is the buffering sequence of DNA that is eaten away when cells split... well as far as a mortal is concerned.
