Time May Be Disappearing From The Universe.

How is it not a dimension? We move through it just like the other three.

Let's go back to the tube. Think of the lenght (time) and the width (space) getting longer and wider respectively. Now what happens when the rate of which the tube is getting longer slows down, but the rate at which it gets wider stays the same? We should see the tube getting wider, faster and faster but we should see the lenght slowing down.

And if this keeps up time should grind to a halt and then the Universe will be a "snapshot" of an instant forever.

That's as simple as I can make it.

Yeah, andother "tube" explanation (I hope) is : do measurement of tube dimensions change in some short timeframe (delta1(width) and delta1(length)). Than do the same later ( delta2(width) and delta2(length) ). Than ratio delta1(width)/delta1(length) is lower than delta2(width)/delta2(length). This means that width rises realtively faster. This can be caused both by width expansion increase itself or length expansion decrease or both. And I guess we can't directly measure time rate change from our viewpoint, than observed result is space expansion rate change.

Can't go backwards in time, yo.

Sorry, time is a dimension.

Though, I mantain I don't believe time exists.

But its still a dimension.

Clever. But those are very, very conflicting statements.

I've given my reasoning, where's yours?

PS: If you want to actually debate or discuss, give some base to your thoughts.

We still move through it. Just because you don't have control over the movement doesn't change that fact.

Einstein once said time is relative. Think on that for a moment.

It is a dimension. Imagine three dimensional cube. Height, width and depth are dimensions.
Now lets assume universe with 2 spatial dimensions (plain). Now u need to allow events in the plain to happen(for example moving points in this plain).. You need to move between "frames". Each frame is one plain. So you need third dimension to move between these plains and u get three dimensional cube , two dimensions are "space" and third is time. Time cuts cube into slices, each slice is one time moment.
It's virtual cube since there can't exist all frames at one time, because it would require infinite amount of energy/matter.

And now you can expand this idea to 4D space and there will be infinite set of 3D "cubes" each representing one time frame, only problem is that we can't draw it easily or imagine it as dimension

Except that you have control in all the other dimensions.

I'll do that. GPS systems work because time is a physical dimension that has a physical effect on matter that passes through it. Time is proven to exist because every single astronaut that has been in space are actually experiencing time before us. Clocks move faster in space, proven fact. Astronauts have travelled into the future slightly, fact. Satellites take this into account in their atomic clocks when determining the position of your car from space.

You can't go backwards in time simply because space may have that 3 dimensional freedom where you can go forwards, backwards, up and down. Time isn't multi-dimensional. It's linear, you can only go forward in time.

and then gone on to say that you believe it's a dimension. So time doesn't exist, but it does?

I can consider several opinions at the same time. I am still stuck to the traditional definition because it's useful, but also question it. Hence why I don't believe time exists.

This could lead to a new theory, but I am not a physicist; so I write it down here to bring something of worth to the thread.

We're not talking about opinions.
You're saying time exists. But you're saying time doesn't exist.
If that's your point, I guess there's no argument, since half of you is on my side.

Man are you ever cocky.
