Where does science & technology end and fantasy begin?

Would you say that the past and future exist right now while we're in the present?

Please answer that as its unclear what you really believe.

I don't know, possibly but I don't think it makes the slightest bit of difference.

As i said has it not been theorised you can time travel at quantum level.

It makes a lot of difference, people believe all sorts because its not made clear by science, i think if you want to call time travel changing the speed at which a thing changes state/position thats fine but i wouldn't call it a dimension as the past and future just don't exist as anything but an idea and measurement.

Quantum accounting for all things very small, how do you travel at a quantum level? you'd have to shrink yourself!

Hawking hinted at the possibility that understanding what happens at a quantum level completely requires new physics, something to bolt on to relativity.

A Black hole for example is a quantum singularity, it defies all known physics and general/special relativity doesn't apply to what is currently known about them so what can be applied to them?

That's the big thing right now in SCIENCE! I suppose

Edit*

I am currently reading The Grand Design (2010) by Stephen hawking & Leonard Mlodinow and hopefully this will give a little bit of understanding to the latest musings!

There's time manipulation happening now on this planet within the hadron collider. particles that are supposed to break down instantly, they've had their life expanded by travelling near the speed of light. Does it not make you wonder what would been seen from the Point of view of that particle?

I dont believe in anything silly, Like travelling back in time, And I only think we'll travel into the future in a form of stasis. If we figure out how to travel near the speed of light, we could essentially move leaps and bounds into the future without getting old

Changed the word travel to manipulation, As it makes more sense

It's been theorised, By an extremely brainy man(So I'll stick with believing him)

That extreme weight\mass causes time to slow down, Hense time travelling slower near black holes.

theorised? havent they proven that time goes slower the faster you go via satellites and atomic clocks etc?

basically the faster you go, the slower time is for you. ergo you could jet off into space at the speed of light or whatever, come back in 5 earth years (as recorded on earth) but you would only have aged by 2.5 years

figures are rough but the idea is the same.

TheCenturion · 4 Oct 2010 at 16:57

erm... fantasy begins when you start dealing with stuff that isn't real, I think

The Running Man · 4 Oct 2010 at 16:57

Which comes back to what do you class as a dimension and time. Iwould say your classification is wring. You can move within time. That change is time and if you can manipulate it then it is a dimension.

i dont think so, you can move in space but you cannot reverse time?

its like you could outrun the light and see back in time, but you wouldnt be able to interact with that light you are seeing, as you are just observing it from a long way away, not physically interactable.

^indeed, But Extreme mass is theorised, Travelling fast proven

I'm not talking about humans, but if you can show time travel at any level however small you have to accept that not only can you manipulate time you can go bac or forwards. If that makes sense.

Radiation · 4 Oct 2010 at 17:06

Here's an interesting thought, what would happen if someone could move at the speed of light back and forth repeatedly over a small distance like a meter, this would probably make him disappear to an outside observer (or not if the distance is less) and to him everyone would be moving slow but he's not traveling through time his clock is just running faster

You seem to be separating change in state to something different to to time. I would say that is the direct response of time and if you change that rate of change it is because you have changed the rate of time. As all scientists currently think and showen in planes and satellites.

The Running Man · 4 Oct 2010 at 17:08

no, you can only slow it down, not make it go backwards.

unless your superman and can spin around the earth a lot and fix thing.s

but if he could do it once, why wouldnt he just do the same thing over and over again to ensure he never gets beaten?

Ok i think we're just coming at the same thing from different angles, when i talk about traveling through time i mean as a dimension, in back to the future doc leaves from one point and appears in another, his car didn't stop and run at a faster or slower rate than the world, he jumped from one time to another.

Time travel in the sense of changing rates is non dimensional as no past or future exists, you can wait for things to change and say you're now in the future but really everything is just in a different state and everything exists together still.

Glaucus · 4 Oct 2010 at 17:15

See just because you can't jump around doesn't mean it's not a dimension. As said I'm pretty sure there is jumpy stuff theorised at quantum level.

As someone else said I'll go with Hawkins and the other physicists who classify it as a dimension.

Radiation · 4 Oct 2010 at 17:18

Well this brings up another point, if it is a dimension where does all the mass and energy come from and how is time quantized, you would need an infinite amount for every past event and what about the future, it must mean it is set in stone, unless you bring up the multiverse which is a whole other level of unlikely.

mrk · 4 Oct 2010 at 17:22

But the reasons for not being able to go back in time have already been outlined and I think hawking (among some other physicists) explained it best.

Forwards? Sure, but not backwards.

Glaucus · 4 Oct 2010 at 17:22

Or like quantum, things change if you view it.

Radiation · 4 Oct 2010 at 17:26

Space is 3D while time could be considered 0D, time would have to be 1D to have a past and future.

Some believe anything is possible when it comes to science & technology but lets be realistic here, when you're playing with a rule set like the universe there are some serious limits on whats possible, things like how advanced, small, fast or powerful something can get, what stuff do you consider incredibly unlikely or even impossible?

Im thinking shrinking an object or teleportation, perhaps there are alternatives like wormholes but thats theoretical, however shrinking an object has got to be impossible?

Arthur C Clarke came up with the following......

Any sufficiently advanced technology is indistinguishable from magic.

Sounds like it answers your question quite nicely.
