Faster than a speeding photon...

[Psychedelic Rhino]

Yes, who's to say.

Problem is, with the theoretical exception of dark energy, we haven't detected any as yet.

[HitchcockGreen]

Or rather, are likely incapable of detecting it.

I am saying that our perception produces the impression of time as a thing, it really only exists for for things that can perceive.
The universe is just a bunch of stuff moving about, it does not stop or go backwards or dilate. If dilation were to occur, it occurs to the perceiver, it is not a property of the universe itself.
Where a human to travel faster than light, they would not travel forwards or backwards in time, but stay firmly in the present along with the rest of the universe, they however would be unable to confirm this as they would be unable to see anything in a coherent manner...

Time is a part of space, hence why velocity has an effect on time. Since everything is relative, time everywhere in the universe is slightly different. Note the expansion of the universe, note that everything is moving away from each other and it is the local movement that only causes minor variations in time.

Time dilation has of course been irrefutably proven with the simple use of clocks and airplanes.

the "speed of light" is just the speed at which that particular type of radiation travels....

Who's to say there isn't a different type of energy that can travel faster?

So do not limit your understanding to the term, use the concept. It is also the top speed of electrons for example.

Please return to the beginning of the thread and read the article and you will find out who is saying there is.

Good responses from the classical viewpoint, but it simply shows that you have not fully grasped what I am actually saying.
A clock is a device used by a person, to assist in defining their perception, it, like the rest of the universe is just stuff moving about. The clock on the moon is not telling the time, it is a machine performing its function, it only tells the time when someone looks at it, "the time" only begins to exists in the mind, because it can remember the past and expects the future.
Time cannot be altered because it does not actually exist to be altered. This does not alter processes such acceleration in any way, or our perception of it. We may think time is dilating, our clocks may show it dilating but it cannot be dilating because it has no existence at all to be dilated.
Of course I could be wrong, I look forward to the successful time travel experiments and resultant universe breaking causality violations they will cause...

[Nielk1]

A clock is a device to measure a repetitive event. Thus in the event this event occurs less rapidly, the measurement shows so. The event used for atomic clocks should NOT ever slow down. But when an atomic clock that went around the planet on a plane, or hell, in circles overhead, is compared to one on the ground that it was synced to at the start, they do not match.

All arguments about time vs the measurement of time are basically bunk and I am a bit surprised people bother to bring that up. The very oscillation of atomic particles have occurred in reduced rate. EVERY SINGLE TYPE of time telling device demonstrates the principle of time dilation with velocity.

Time travel backwards is impossible nay for one single oddity and time travel forwards is a simple matter of moving really fast.

There are claims you time time travel backwards by a method related to spiraling particles, but you cannot go back before the tunnel was first made, and it is only theoretical.

Now, if people really want to still get too involved with semantics when it comes to time and measurement, TIME, and I mean 'THIS IS TIME', is the expansion of the universe. That is right, time is part of space itself. Space is not nothing, space is time and existence itself, and as space expands, time elapses. Compress space and you can reverse time, however I don't see anything taking all motion in the universe and reversing it any time soon.

Nothingness travels faster than everything else. ^_^

[Ded10c]

Nothingness isn't a something, so how can it move?

[MrTwosheds]

So here we have the crux of the misunderstanding, Is Time a property of matter/energy/the physical universe? Or is it something that only appears to be happening once you have an observer to perceive it?
A failure to recognise the importance of the observer could be a serious error, man may have searched for the tachyon in vain, by simply failing to understand that they are themselves the tachyon. A Universe without observers, could not be described or have properties such as time attributed to it at all. The observer is an important component of spacetime, its abilities and limitations should be considered.

Nothingness isn't a something, so how can it move?

It does not need to, it is infinite, It is everywhere at once, it is the real space-time, its value is always 0. And it hates mathematicians

[Psychedelic Rhino]

Twosheds, your approach reminds me very much of a derivative of, 'Model-dependent realism' in which, "the idea that our brains interpret the input from our sensory organs by making a model of the world. When such a model is successful at explaining events, we tend to attribute to it."

Esoteric arguments can be made whether or not the 'mind' invented, and is therefore the tachyon, or it is an idea never intended to be part of our current reality, or if time is merely an invention of the consciousness. All that is fine to contemplate and reflect, but it has been objectively shown that 'space-time frames' must be considered to make "our" [sic; all that is known] interaction with reality functional in our daily existence.

Rhetorical question.

[MrTwosheds]

Rhetorical question.

Maybe, but a very good one. Clearly "Nothing" has a very important role in allowing the Universe to exist at all and it has a profound effect on everything in it. It is not a subject of intense scientific study for obvious reasons.

[Psychedelic Rhino]

I once caught hell for mentioning a universal expanding sphere into 'nothingness' by my astronomy professor years ago.

And he proceeded to lecture on the confused perspective for 30 minutes. . .

There is not even 'nothing' beyond the 4-space.

[MrTwosheds]

Yes, in some bizarre way, science can be much like religion...in scientific terms Nothing = Satan (joke) It cannot be quantified, measured or observed and thus is very very unwelcome, and confusing to talk about.

There is not even 'nothing' beyond the 4-space.

There is no difference between "not even nothing" and nothing, same absence of quantifiable anythings. Deciding nothing does not exist is quite sensible, it doesn't. Now imagine a Universe without it. That's right, pure solid condensed stuff, not a planck length between anything, no matter, no energy and certainly no irritating students asking questions that cannot be answered.
It is the border of science, beyond it no instruments or calculus are of any use. But we know its there allowing things to exist by contrast. Zero is a number.

Does this mean I have to buy a new GPS? My old one doesn't seem to be working anymore...

[Red Devil]

"The Nothing" is filled with dark matter, so it should be referred to as something else, like maybe, "The Stuff" or, "The Invisible Black Yucky Stuff"
