Fabric Definition and 119 Threads

Interesting article on a 57 dimensional structure mapped out recently. http://www.telegraph.co.uk/connected/main.jhtml?xml=/connected/2007/03/19/ecpattern19.xml

Textbooks usually illustrate space and our solar system with the planets lying on a sheet where the heaviest object at the centre is the sun. Other planets surround it in orbits. The attraction towards the sun is due to the dent created by the sun. This is a result of GR. If this theory is...

Hi I am reading 'The Fabric Of the Cosmos' by Brian Greene. I am not able to understand a particular part of it.I have a doubt as below. In one of the chapters he says that suppose there are two observers. One on the Earth and the other one on a planet (lets call it planetA ) which is 10...

Anyone else scared that the veil is causing the sane to be outnumbered (and out-believed) by the "majority". Ever read Ishmael...I know, i know, its only one book, but the idea of religion as mythology is pretty sane, IMHO. Wanting an explanation for "it all" is not the same as having one...

Hi guys, I had an idea on the formation of worm holes...I'm not sure if this holds up at all but here goes. The basic idea is based on an elastic band. If you stretch an elastic band beyond the elastic limit, cracks start to appear until eventually the band will break...Now, imagine that...

Even Einstein said that it was important to be able to visualize concepts. Words are important tools we use to visualize concepts. Aren't present words used in relativity like warped, bending, fabric, and sheet confusing? These are words we generally use to depict 2 dimensional concepts...

If space-time looks like a piece of fabric (or an inflating balloon, in the inflation analogy) what is on the other side of the fabric? Or does space-time not look like a piece of fabric at all...? Like some scientists are suggesting that it is a fluid...?

According to General Relativity the stars and planets cause a warp in the fabric of space time, right? Now, if planets' orbits are governed by the warping of the fabric of space time, then how are the gas clouds in Nebulas affecting that fabric? Also how do galaxies affect that fabric? Do they...

I've heard there is a maximum magnetic field intensity in a neutron star. could this be related to the properties of the fabric of space time. I'm thinking of the idea that mass distorts spacetime for example the bowling ball in the sheet demonstration. My question is, is the max magnetic...

when laying my carbon/kevlar fabric i constantly have the problem of it sticking to my gloves which is quite annoying and makes it hard to handle should i be using specialy coated gloves? do they make such a thing? or is there a "lay-up" procedure that anyone knows of for laying composite...

Books like "The Fabric of the Cosmos" and "Parallell Worlds" and "The Elegant Universe" Are there any new books out similair to these? I have finished all three of them, and have the taste for more. Please recommend some books, thanks!

If a piece of fabric was stretched out, and I pushed my finger into the fabric with a force of 5N, the fabric will push back the 5N because of its potential energy. correct? So what if I did the the same thing and pushed my finger agaist a wall? The wall doesn't stretch but it still pushs...

Is it possible that a fabric can be used as a diffraction grating where in the space between strands of threads is a small fraction of a millimeter? My answer is yes. does it mean that the light can be bended due to this? I mean how come?

I remember reading a while ago that the fabric of space has a texture and thus would cause friction. Even in a perfect vacuum a spacecraft would slow down over time due to this. Is this an accepted theory?

Can we say that non-linear fabric of space/time (n_Dim fabric that is curved toward n+1_Dim) is an anti-entropic zone? And if so, can we understand life phenomena as an anti-entropic zone that can duplicate itself?

I have a copy of Brian Greene's Fabric of the Cosmos in my hand, just starting to read it.

I have come up with my own theory, but only from minimal knowledge of the subject, it does not defy relativity, the definition of forces, but it does define the effect of gravity as a multiple functioning force that interacts with space fabric to make a diffusive pull. It also helps to explain...

I've been reading a lot about gravity lately, trying to understand it as best I can. When I think of gravity, I find it easiest to imagine the rubber sheet analogy to explain the spacetime curvature. Gravity is supposed to be caused by the curvature of spacetime. So the thing that I have no...

Refutation of reductionism (excerpt from "The Fabric of Reality," by David Deutsch) The whole title of this thread should read "Refutation of reductionism as a fundamental explanatory framework (excerpt from The Fabric of Reality, by David Deutsch)" but there wasn't enough room for that...
