Space tearing conifold flop transitions in Calabi-Yau space?

It’s fine if you want to talk about it, but as I said before there are other forums (like the link I gave) that cater more specifically to your needs. I know you said that forums like the one I gave a link to tend to make things difficult but that’s just because the concepts involved in such matters are hard.

To expect people here who are mainly not into advanced physics to not only understand the concepts themselves but to then translate those ideas into layman’s terms so you understand them, is a bit unreasonable. I’m sure if you explained on the advanced physics forums that you needed it explained more simply, they would help - after all the purpose of forums is to elucidate not obfuscate.

That link I gave goes directly to the topic in question and despite the fact I’m not really into physics (although I have a degree in physics), I understood what they were on about mainly. As I said before, would you expect me to be able to come here on a computer graphics forum and ask about the mating cycles of the hairy-eared dwarf lemur or a simple proof of Fermat’s last theorem and get a satisfactory answer?

Don’t take it the wrong way, very few (if any) subjects are excluded from the off-topic sections - you can probably tell this from the fact that a post titled BWRAAAAAAAAAAAAAAAAAARG!! got a sticky - but if you ask the people who do advanced physics for a living, you might get a better response. Of course if you get a good answer to your post here, great. :slight_smile:

I think I am going to give osxrules a nomination for ‘most perfectionist’ poster on elysiun :smiley: :smiley:

Not only that … most of the people seem to be average 15 … (Not me…and my age is not important untill I know that there is someone older haha)…
Anyway … I am starting to think that I am too old for elysiun…somehow…

I realise, I became 17 last monday and have been on elysiun for a few years now.

The mating cycles of the hairy-eared dwarf lemur would be a specialist topic, that even advanced biologists would probably not know about. However, calabi-yau spaces are a particle physics thing that anyone sufficiently advanced in the subject would know about.

You wont get a simple proof of Fermat’s last theorem, because it is incredibly complicated. Calabi-yau spaces are just a quite unusual idea.

The title was a bit showy, sorry, but it got interest.

The question was a stupid one and I retract it, as I said earlier.

I don’t think there’s anything wrong with posting threads about complicated things on Off Topic. As a result of your post, I now know that there is something called Calabi-Yau space and that its got something to do with string theory and that space tears.

However, I have no idea what all this means. I think it’s good to be better informed about the world around us and in developments in science and arts. It would be nice if we had a point of reference about what Calabi Yau space is about and why string theorists think it is important. I doubt that your question is a stupid one, but it would be good if we had a bit more to go on.

I was especially interested in how we could use Blender to map out 10d space! I’m currently managing 4 dimensions with my solar system. How do I add an extra 6d for instance?

[edit] btw, what is Fermats last theorum about and why is it so important? How come it is difficult to solve? Has it been solved? And will it help us to live more productive and creative lives?[/edit]

You’re right, but often it just gets people confused when few people know enough about the subject to make sense of it all. Especially if people pretend they know about it and actually just make up a load of BS. :-?

Check my first post - there’s a link to an advanced physics forum that sort of explains a bit more about it. I agree with you the question is not stupid - heck, we can answer stupid questions. :wink:

Do you mean 4 including time? I don’t think it’s possible to make anything higher than 5d on a machine with a 2d screen - 4 spatial, 1 temporal. I think it’s been done with a hypercube before.

Fermat’s last theorem was possibly the most difficult mathematical problem to solve as it remained unsolved for hundreds of years:

It’s fascinating because the theory itself is so simple - one equation. As for the implications, probably a lot to mathematicians and other theories but in the real world, who knows - it may even help you visualize 10d space on your computer or prove that you can’t. :slight_smile:

yes 4th for me = time. But how do I manage to squeeze another dimension in there? I’ll check your previous link to see if I undertstand.

anything can be projected in lower dimensions, heck, anyone read flatland?
so if a model could be mathematically made in 10D and then visualized in 3D, it could be done. If someone modelled 3 dimensions at a time it could be done. But for no reason, of course.

Check this link for seeing how to make a cube into higher dimensions:

Yeah, I think that link above suggests any dimensions are possible but it gets pretty hard after 5d especially with complex models. Also, you might have a seizure watching higher dimensions. I think that’s the basis that optical illusions work on. The hypercube itself is an illusion:

http://www.davidpbrown.co.uk/optical-illusions/hypercube.html

I don’t think it’s possible for human minds to visualize higher dimension stuff:

0D = a dot
1D = extrude the dot in one axis to get a line
2D = extrude the line to get an area or plane
3D = extrude the area to get a volume
4D = add a timeline
5D+ = extrude the volume somewhere and have this extrusion change with time - it will look like an illusion
6D+ = ??? I guess extrude the volume somewhere else.

Maybe this explains a bit better:

The 10 dimensions are all spacial, there is an 11th time one (in m-theory).

Havent read flatland yet, its on my list of things I want to do though.

I have made a 4d cube, thats quite easy, though I could only rotate it in 3 dimensions.

For me, over 4 spacial dimensions and I cant see it.

These calabi-yau spaces arent 6/7d shapes, they are 6/7 dimensions curled up into strange shapes. One important part of string theory is finding the shape of these dimensions. This is because it has immense importance on how strings vibrate, because they vibrate in all of the dimensions.

The question is stupid, because it was obvious. The scale of these dimensions is of the order of the planck length or less, so to shrink a sphere, the sphere must actually be the dimensions, not an object.
