Dark, Cold, Space. Do these exist?

[Rokenn]

An interesting note on the concept of 'space'. Solid mattter is actually made up mostly of empty space. I hope I remember this right... If you were to take an atom and expand it so that the nucleas was as large as a cherry, the elections circling it would be about a 200 yards away and the size of a grain of sand. It's a wonder we do not fall through the floor!

What I learned was that it gives me a headache so I don't do it any more.

Quoting one of your compatriots : "At the beginning, there was nothing, which exploded".

There is a source of coldness. What about blizzards, chill winds and such. The other two are pretty complex. Darkness is just lack of light, there is no source for it..And I have never really pondered the space one.

A blizzard and chill wind don't create cold, they are cold because they have no heat.

The default setting for the universe is cold, not hot or luke warm. If nothing existed, all would be dark, cold and space (nothing). No heat, no light, no matter.

In our universe suns create heat. Movement, friction, life itself creates heat.

On the matter of space, space is nothing. On earth, what we call space actually contains air, but the word space is in this case defined by a relative lack as has been stated.

However, on the matter of space being infinite....

How can space be infinite?

So the universe is expanding (which implies a limit or end, for only that with boundaries can expand their boundary otherwise it would already be where it's expanding into) fair enough, and it has said that it's expanding into infinite space.

But space is finite. It stops where something is. Finite. WIth limit.

There is no space where there is a sun. Or a rock, or wind, or a tree, or an asteroid.

So space is not infinite, because it has finite boundaries of substance.

So we have a finite universe expanding into finite space, though it could expand infinitely.... or will until it contracts.[/QUOTE]Ahhh ... some pretty paradox(es, i, en?) you have stirred up Yorick! Here is a rephrase in a slightly different way.

The distance between two points is finite - yet the number of points between those two points in infinite!

On the heat thing - there is always heat as heat is energy, and energy is neither created nor destroyed (at least to the understanding of us lowly humans), just transformed.

Cold and warmth are relative descriptions of heat levels between two objects and the rate of transfer from one to the other. A block of ice is "cold" to me because it is at a lower energy state than I am, and my heat is conducted to the ice until our energy levels are equal. To the block of ice by the way, I am "hot". (Yuck - thermodynamics)

Anyway - this whole negative thing, you can not prove a negative, only disprove a positive. You can prove that certain positives do not meet the condition of the negative, but that still does not prove the negative.

Ok my head hurts now ...... deep topic Yorick!

That is very interesting indeed.

Heat is a form of energy, therefore we can pretty safely say it exists. Cold is just a lack of heat. The slower particles vibrate in a mass, the colder it is and the less heat it generates. LOL those people who said there are sources of cold like blizzards. LOL. It's funny in a cute little kid way, no offense intended.

Anyway, heat is a measure of speed of particle vibration therefore heat = fast vibration, cold = slow vibration. It makes sense to say there is a source of heat i.e. energy and cold is a lack of this. Absolute zero is the least possible vibration i.e. there are no particles to vibrate. Therefore, cold does not exist only a lack of heat, if you follow.

The same goes for light and darkness. Light is a form of electromagnetic energy and darkness is the lack of this therefore dark does not exist only a presence or a lack of light i.e. energy.

Space also does not exist as it is a lack of matter.

And also there is a minute chance that every time you poke the table your finger will actually go right through. A mathematically proven very small chance. [img]smile.gif[/img]

Damn I need to remember more of my physics!

If Cold is nothing but a lack of energy (heat)
and Dark is nothing but a lack of energy (light)
and Space is nothing;
It can be concluded that Cold, Dark and Space are one and the same.... [img]tongue.gif[/img]

But if he cant lift it, he's not omnipotent.. and if he cant create the rock, he isnt omnipotent either.

But you are misunderstanding what we mean by "omnipotent". Omnipotent means able to do anything--which includes creating any object conceivably possible to exist. A rock "too heavy for God to lift"--which cannot exist--does not count in this.
