Raster's theory of gravity

[alexrudd]

[MathStuf]

All that has been determined about the extra dimentions is that none of them are larger than 10^-4m when curled up. With gravity being such a feeble and weak force, it is difficult to test a deviation in its strength on such small scales. Oh, and if enough new particles are found with properties that correspond to those predicted by string theory, will that convince you? As of now, new accelerators being built may have enough energy to find new particles and get their properties.

[Liazon]

They're just so friggin' tiny!

[Jeremiah Walgren]

If they can detect new particles predicted by String Theory, that'll be good enough for me. I have yet to hear about such discoveries, though.

[Liazon]

The problem is there's only one kind of particle (that's actually not a particle): energy! String Theory says the universe is made of tiny vibrating strings of energy. The way the strings vibrate determine how they interact, giving matter its various properties.

[Radical Pi]

I wouldn't expect this to work in F-Theory (10 space dimensions, 2 time dimensions).
And, a random theory I would like to add to the controversy:

An infinite number of parallel planes can exist in space, thus an infinite number of parallel spaces can exist in 4-dimensional hyperspace. Our technology is now great enough to have papers (planes) stacked on each other. So, 3-dimensional figures could hypothetically be copied and stacked to create 4-D versions of ourselves.

...Theoretical Physics is almost as cool as calculators!

[Liazon]

wasn't the original idea of hyperspace based on the idea that in the 4th dimension, distances might be significantly shorter?

[DarkerLine]

"In the 4th dimension"? If there really are 4 or more dimensions, you are always in every one of them (it's not a different space, but rather a new way to measure space).

[Liazon]

-points to idea that not all dimensions can be percieved-

[Jeremiah Walgren]

So, if there are more than three spatial dimensions and we exist in each of those does that mean that our bodies are more advanced than our minds since we can't perceive those dimensions?

[Weregoose]

As a rhetoric device, define "advanced." Personally, I don't think logic, intelligence, philosophy, or other such individualized terms of comprehension are factors in this matter. It is merely what it is.

[Raster]

Wow, I wasnt expecting so much talk about this . I dont know what to say now . Exept Jeremiah Walgren, This is now what I do (ever since I lost interest in alot of things), I mainly think about the unknown, and the things we dont quite understand. It seems like a puzzle to me, certaint things fit into logic, certaint things dont.

Well, since we moved onto dimentions, I guess I will give my definition of a dimention... Another word to describe a variable.

A good example of dimentions in directions is a satillite. X, Y, & Z describle the position of the satillite. V & W are used for the up/down angle, and the left/right angle. All of these variables have an effect of what the satillite communicates to.

A dimention in everyday life could be the weather. One day could be rainy, and one could be sunny. The rain/sun can affect how our day will be (such as a bunch of other things).

I think I gave out some pretty good examples .

[EDIT]

And I think things like speed, distance needed to travel, can be conciderd a dimention.

For the follies of describing extra spatial dimensions in a 3D world, you might want to take a look at Flatland by Abbott. ;)

Anyway, among the sea of arguments going back and forth, I wish to address one point raised. It was said that the force binding nuclear particles can be thought of as gravity. This would imply, I suppose, that if gravitons existed, they'd be the same as gluons? Unique I'd say, but then again, we now have something called electro-weak... ;)

Proving this, would be the particular difficulty.

If only it was just The Force, The Energy, and The Matter. Then it'd all be so simple. Actually you might be able to simplify it to The Thing! or The Existence!

As for percieving dimensions, does a bacterium percieve dimensions? It's like a machine. It responds to external stimuli to change it's shape and direction. It homes onto food to maintain life. It doesn't really have a sense of direction does it? Yet it exists in a 3D world. It could be existing in an 11D world! That bacterium could be us, and there could be greater beings in existence out there that don't care that we are so dumb we can't see the extra dimensions. btw, how can there be 2 time dimensions?

And how many points do you need to plot something in space? 3? cuz I heard once you need 6

[DarkerLine]

Depends on what you're plotting. A plane needs 3 points.

[thornahawk]

DarkerLine is correct. Remember that basic geometry postulate: "Lines are uniquely determined by two points, planes uniquely determined by three points, spaces uniquely determined by four points, yada yada..." :D

calcul831415, c'mon, go look for a copy of Flatland in your local library or on the web. I think it will be interesting to you at the very least. ;)

You can prove that the electromagnetic force isn't the same as gravity (like between a stool and the earth) this way: A strong magnet can lift the stool (if it's metal), negating all of the earth's gravity and still having enough left to lift the stool. This shows that gravity is much weaker than the electromagnetic force. Plus, gravity works on everything, electromagnetic only affects those with charges. And to show that gravity can't be impostered by another force is that the electromagnetic force would overwhelm gravity and make protons fly apart, but the strong force keeps them together. And the strong force is only applicable on very small ranges.

And FlatLand can be found here: http://www.softpedia.com/progDownload/Flat...load-26791.html

[Liazon]

So much for Einstein's dream of Unification

[MathStuf]

How does that destroy unification? He wanted Quantum Mechanics and General Relativity to be happy with each other. Basically he wanted them to be generalized and shown to be the same thing.

[Liazon]

my bad.

But I also thought gravity vs. the nuclear forces was one of the reasons why he couldn't do that.
