Energy and Matter, Time and Infinity

[TMA_1]

Energy and matter at the point of lightspeed are one in the same. they are in fact the same thing. Everything is made of energy. What is time to infinity though? What is space? is it nothing? I have heard that it isnt, that there are things not descovered yet. What do you guys all think about this stuff? just spew out on your own opinions. I am not asking for scientific babble I am just wondering what are your guys' thoughts on this stuff.

[emprworm]

space in our universe is actually something. it is known as the "zero point energy sea". it is not an absolute (classical) vacuum. to explain in laymens terms, all of space contains 'background noise'- scattered quantum particles buzzing about like little bumble bees

-cute lil' suckers :)

[Anathema]

Discussions about infinity always end up giving me a headache :)

[Khan]

Well I reckon time and space are one in the same so time and matter must be the same because space is made up of matter. Time, Space, Energy and Matter must therefore all be one in the same.

You are getting to blind way, something like four elemental teory. But time ISN'T. Humans are very specifical creatures, because they have power to create a physical law to understand other. Time is our invention, but it flows untouchable. Nothing can influate it, because it does not exist. It is human sense, not physical thing.

Infinite space... What is space? 3D area? Then it isn't infinite. Only oo-D area is infinite. But at core, it is a vacuum, zero "sound" of the superstring. Or it could be their "perfect harmony". Matter and energy are the "odds" in it.

[aox0m0xoa]

energy and matter are not the same thing, sound is energy, but not matter. they can be converted to one another, but they are not the same.

[Caid Ivik]

Of course not. Matter is other, or better, opposite form of energy "tone".

[TMA_1]

Sound is matter because it uses an atmospheric medium. Notice that space doesnt carry sound because of vacuum. Energy and Matter are one in the same.

Also time is substantial and isnt invented. Notice a star or other large body in space. There is a curve in space-time. Actual warps in time that occure by large bodies. Black holes too actually extremely warp time because of their extreme gravitational pull. It is substantial just like matter and energy. Just in ways we dont completely understand.

[Khan]

See see he understands I was sorta right ;D

[Edric O]

Energy and matter are indeed one and the same, as we all know:

E=m*c^2

As for time and space, together they count 4 dimensions. Recent studies have shown that the universe could have as many as 10 dimensions. However, the 6 extra dimensions are curved in on themselves, and extremely small.

Let me explain the concept of a dimension curved in on itself. Imagine a circus performer walking on a tightrope. Because of his size and the thinness of the rope, he sees the rope as being one-dimensional (having only length). This is how we look at the universe.

But if there's an ant on the rope, it being much smaller than the human, it can perceive an extra dimension, very small and "curved in on itself": the width of the rope.

Of course, in reality, these extra dimensions would be much, much smaller.

[quoudam72]

Each dimension being smaller than the previous dimension, yes?

[nemafakei]

"these extra dimensions would be much, much smaller"

By what standards, though?

That makes no sense - like saying length is shorter than depth.

There are at least 11 needed for certain phenomena (anyone heard of m-theory?)

I don't see why or how there might be a finite number like that, though. I think there is an infinite number of dimensions.

[Edric O]

That makes no sense - like saying length is shorter than depth.

Both length and depth are infinite dimensions. That is not what I am talking about.

The extra dimensions can be viewed as multi-dimensional "circles" with extremely small diameters (about the same as the diameter of a lepton or quark), existing in every point of our normal space-time.

[Anathema]

Trying to imagine other dimensions is hardly good for your sanity.

Curved dimensions? I read an article long time ago, stating that other dimensions can best be imagined as tiny spheres.

And Nema, exactly what do you mean by infinite? Do you mean that matter exists in an infinite number of dimensions or that some matter doesn't exist in our dimensions?

If there are other dimensions, we would exist in all of them. Just like a 2d only object couldn't exist. The smallest particle would still be the minimum thickness.

[nemafakei]

So are we talking dimensions as in length and time here, or something different? what divides them? Why are they both called dimensions, then, yet mean something very different?

"Do you mean that matter exists in an infinite number of dimensions or that some matter doesn't exist in our dimensions?"

Everything exists in all dimensions (else it does not exist - a 'square' does not exist). It's just that we can't easily tell things position in more than 4 dimensions.

[Anathema]

Say if an object moves in the "vertical dimension", meaning upwards or down, I can tell. But if we can't perceive other dimensions, wouldn't any object that moves in such a dimension disappear from our sight?

Put differently: if on a 2d platform (imagine a paper sheet), you got a man and a tree. Suppose you lift the tree upwards, away from the platform, the guy wouldn't be able to see it.

[Edric O]

They are dimensions in the same sense, but not in the same "shape"... or, to put it better, I have no idea whatsoever. :)

My main source is an article in the French magazine "Science & Vie" about 6 months ago. I have also read similar (but less detailed) explanations from a number of other sources. But I am no physicist...

[nemafakei]

Yes, but it still exists in other dimensions.

It all depends on our consciousness, and what we perceive. I can't think of an easy way to explain it...

[Edric O]

Because of the circular nature and the smallness of the extra dimensions, an object moving through them would get back to the point of depart within a fraction of a nanosecond. Think an airplane doing a looping.

[Anathema]

But if it exists in other dimensions, it is necessary that all matter in "our universe" doesn't move in the other directions. Doesn't that sound a bit unlikely? With the 2d platform, the guy would wonder what the hell happened to the tree if we pick it up. But no such thing is happening in our world.

[quoudam72]

The world we live is 3+1 dimensions the fourth being time. Although time is very different from the familiar spatial dimensions. The string theory a quantum theory of gravity. With this description of gravity, one needs more than 3+1 dimensions, and the world around us could have up to 11 spatial dimensions.

According to string theory then, we live in a universe where our three familiar dimensions of space are but there are additional dimensions which are curled-up very tightly so that they have an extremely small radius: 10-30 cm or less. These extra spatial dimensions, if they really exist, are thought to be curled-up, or "compactified". Edric is that what you were refering to eariler when you spoke of the airplane doing a loop?

My head hurts! My head hurts!

[Caid Ivik]

Each dimension being smaller than the previous dimension, yes?

0D space, or point, is only dimension not infinite. It is fully zero. But 1D is infinite - lenght could be 1 as like oo. When you will give there other dimensions, you would think that it is bigger, but you can't enlarge infinity. Like there are integers (1,2,3...) , which are part of real numbers (including pi and partials). But there can't be more real numbers (altough all logic leads to it), because total number is not definable. You can't measure it. Mathematical nonsense, like 1/0.

[The_Sadukar]

my head hurts as well

[Caid Ivik]

Take aspirin.
