If time didn't travel in a constant straight line... how could I tell ?

Time is always a problem for me... Nothing in nature is constant it seems.. so why should time be absolute...

I would go a step further and sugest that time does not exist in the big picture, not linearly or circular (which is just a cruved line anyway) time is a construct of man. It does a really poor job of explaining causality, this happened because this happened because this happened, this faulty logic begins to break down when talking about grander concepts, such as the "beginning of time" "the end of time" It's pretty clear that the universe has always existed in some form or another, this concept of an infinitely old universe just destroys the concept of time altogether, you can't have infinite time, it doesn't mean anything, time jus tdoesn't exist everything always is occuring simultaneously all permutations of the universe exist simultaneously the illusion of time is just because the tool we use to view the universe (our human body) can only process so much information at once and is limited by the senses and a brain that can't concieve of the terms infinite or nothingness. When looking for answers to questions about time, the eastern world has for thousands of years been answering these questions, the western philosophical linear thinking model has only been takling these questions for a relatively short amount of time. I urge you to read a book called the Tao Te Ching, it is the difinitive guide to understanding the universe from a non causal, non-linear perspective. really mind blowing for some scientists stuck on more philosophical questions.

A quote from the tao te ching, explaining the difference and similarity of abstract knowledge versus experiential understanding

"The Way that can be experienced is not true;
The world that can be constructed is not real.
The Way manifests all that happens and may happen;
The world represents all that exists and may exist.

To experience without abstraction is to sense the world;
To experience with abstraction is to know the world.
These two experiences are indistinguishable;
Their construction differs but their effect is the same.

Beyond the gate of experience flows the Way,
Which is ever greater and more subtle than the world. "

Time doesn't travel in a straight line, it is merely relative to the speed of light. The closer to the speed of light you get, the slower time goes by relative to a stationary point.

If there were twins, and one left on a spaceship going 99% of the speed of light, and returned 20 years later relative to the earthbound twin, the space traveler would only age 2 years.

This theory was established by Einstein's theory of relativity in the early 20th century. You can tell this is true from observation. Scientists went on a jet with a very accurate clock and flew for 48 hours. When everything was done, the clock on the plane was different from clocks on the earth. The difference was only a few nanoseconds, but this still shows the theory of relativity.

Relativity addresses the rate at which time passes, not it's linearity.

It would not be air differences since they are atomic clocks, and aren't affected by that sort of environment. Also, the clock both gained and lost time, depending on which way they traveled (the spinning earth means they move either faster or slower). The time difference came out exactly with the formula prediction.

This has also been observed through radioactive decay. Since these particles move close to the speed of light, they decay at a much slower rate than when they are still.

If there were 2 twins both 10 years old, with one of the twins traveling away into space at any speed and returning to Earth after 20 years. Why wouldn't the space traveler not be 30 years old if he/she has been away for exactly 20 years from Earth?

Doesn't traveling at the speed of light only means the space traveler will be able to travel at much farther distance while the time relative to Earth will remain constant?

Could the tiny fractional nanosecond difference be caused by the variable factors the mobile jet is exposed to? For example, air pressure in higher elevations or magnetic fields/microwaves from satellites and storms that can affect mechanical and electronic components in mechanical or digital clocks?

Time is not absolute - it is relative to where you are standing in the universe . Time only seems absolute at our level - we are born before we die. However at the quantum level, physics breaks down and with it our linear concepts about time -past, present and future can happen simultaneously. For more about this look into Heisenberg's Uncertainty Principle -on the quantum level, if you know "when" you can't know "where" and vice versa.

Just what I was thinking, about Heisenberg's Uncertainty Principle. You can't know when and where at the same time.

Good point with quantum physics. Einstein really was held back by his unending quest to keep relativity intact and reject the future of modern physics. String theory and parallel universes are among some of the more interesting things (IMHO) to come out of modern physics. Of course, time travel has always been the discussion of much debate. We are, of course, all traveling in time: forward at the same rate (unless we are astronauts on a space mission). See my answer below for interesting video on the discussion of time travel being like a river.

The rate of time passing does not relate to it's linearity. The only non-linear type of time that comes to mind for me would be some form of reticulating time lines, leading to perpendicular worlds. There has been a lot of scientific discussion about this, and the possibility of a multi-verse. (One of the first I was aware of was Hugh Everett's 1950's many worlds model.)

But aside from theories and mathematical proofs, to experientially confirm that we were moving down time paths that might be taking right turns, you'd need to be able to travel between, or at least view, these world variations.

There might be some way to do that with yoga, but it would be tricky to know if it was "real" or imagination. My friends at incunabula claimed to have made a mechanical way of traveling between worlds. But I would say, as of right now, confirmation is still a sticky subject.

Part of the problem with your question is that it assumes that "time" travels. It is our own *awareness* that travels and time is one way of measuring its motion.

With that understanding, memory and imagination become two of the greatest tools we have for exploring the mysteries of time. Both of those facilities free us from the restrictions of our physical existence and enable us to get in touch with events that are outside the realm of common space/time perception. But this is a tricky and unreliable process at best.

It can take years of self-discipline to learn to separate your desires and interpretations from your perceptions while in the trance-like states that accompany deep exploration through memory and imagination. Without that separation you will frequently end up fooling yourself about what you see - and even with that discipline it is easy to misunderstand, so it becomes vital to always check facts as deeply as you can, and to always be ready to be wrong.

Nevertheless, in the middle of it all, you will find some startling and compelling proof that time is not linear, that we are all connected to each other, and that the real work of our lives is gather to ourselves the bright fragments of that which we desire the most.

Time is a human construct, it is meaningless to try to analyze it. It is arbitrarily based on what we can observe around us. Instead of using the passing of night and day as the basis for time, why did we not use a different standard? It all depends upon us.

This question does not have an answer. With that said, here are two observations.

(1) Marking the passage of time is subjective. It's relative. Didn't Einstein say something like, "When you sit with a nice girl for two hours, it seems like two minutes. When you sit on a hot stove for two minutes, it seems like two hours that's relativity."

(2) Your question implies something about the geometry of time (i.e., straight) and it's passage (i.e., constant). Some are responding to this question by making the jump that 'not linear' implies the existence of self-intersections in the passage of time. There are many non-linear curves that never self-intersect. Examples: a sinusoidal curve in 2D, a circular helix in 3D.

Our speculations, here in the MA forum, about the nature and geometry of time are not going to be nearly as illuminative as a study of Brian Greene's books, those of Stephen Hawking, or other gifted expositors with deep training in physics or cosmology.

Time doesn't necessarily travel in a straight line. In fact, some physicists believe that time travels like a river, complete with whirlpools that can catapult you back in time. Dr. Michio Kaku has a great discussion on the subject here:

Time is a myth - a lot of great answers so i will save my normal response and think of something unique. time does not travel in a straight line, it stands still. we now have the ability to slow down light and observe it as a matter of past and present behavior. what is actually happening is that the universe is moving past us. as i type, time has not passed, i just witnessed something that already happened and it wasn't time that measured it. it is just where we happen to be standing when we observed such things. (no, i have no idea what i'm talking about, at least i don't think.)

Time is linear because time is one of the 4 known dimensions, and each dimension by itself is linear. Time is not absolute, as shown by Einstein's theories of relativity. The only thing that is absolute about time is that it proceeds in one direction, the direction in which disorder increases.

Time travels in a straight line, but not at a constant rate. If two precise clocks were synchronized, and one was placed in a higher gravity system, then the one in higher gravity would be notably slower when they are reunited. Time in a high gravity system is relatively slower than time in a low gravity system.

Time is a system of description attempting to reconcile what we observe with what we think we know. It is a unit of measure, not a living entity with independent motion. Differences in your own perception may happen but when scientists claim it's because time is bending, shifting, going backward or speeding up or slowing down that's really just their way of saying "We don't have any real way to explain it so we'll claim that a system of measurement (time) has mystical properties instead."

for all you know, time stopped for a million years (ok, i know... if time stopped, who counted the million years?!) just a few moments ago, then started again. we didn't notice. (because we're in the same perceptual frame that might have paused)

so, don't worry about it.

Interesting. But there are so many other things in life you could be better spending your time on, ladies & gentlemen. Trying to be clever and work out these things that are beyond the true comprehension of even the worlds leading scientists is like spending your life jumping on the one spot trying to reach a bar of gold suspended 10 metres above your head - you won't succeed.

One word that appears above is "theory" - it tells the story. The very word "theory" means unproven.

If you get your kicks from these kinds of purposeless discussions (no insult intended), then continue. But there's so much more you could do with your time and intellect that would actually be beneficial.

why waste time telling people they are wasting time....I think that is an even bigger waste of time than contemplating grand philosophical concepts. These are concepts that are at the forefront of theoretical physics, and yes scientific facts always start out as theories that doesn't make them useless, the theory of gravity proves very useful for many fields of science even though no one has ever figured out what gravity actually is, just how it acts.
