Some String theory questions.

This theory is so cool but I have a few questions about it.A demension allows movement right and we have 3 basic spacial demensions. Since time is also a demension and movement requires energy is there a way we can apply energy to something in the 4rth demension (TIME) and speed up time. It is kind of hard to explain what I am talking about and maybe I am not sure how it all works so I need to know if I don't know what I am talking about.What would it look like if all 11 demensions were visible to us. What would allow us to only move in 3D and not 5D. We can choose only to move 2D left and right and up and down or 1D left and right or 3D all at will. But can we choose between wheather we move 5D or just 6D or just 5D. Know what I mean?I don't understand how time travel can be because if you go back in time in order to accomplish something then you accomplish you wind up removing the reason for going back in time in the first place wich means you never went back in the first place but if you did not go back you never changed anything so everything is as it was before going back.How does string determines what type of particle or atom something is. I don't get it. If it vibrates with a higher frequency it's hidregen but a little low oxegyn? That doesn't make sence. It must be a little more complex than that. Please explain how it works.If we master the strings than we could we make any type of matter we want at will with a materializer.If there is a rip in space and you put your hand in to get to the other side then want part of your hand be not there. When somebody looks at it won't they be scared to see your innerds? Will they even be able to see it? How will it work.What would happen if we turned all the strings that make us up into loops would we be free to roam all dimensions or would we turn into something else like different matter. Then we would roam but without life.How can we go into the future if something hasn't happened yet? I figured as we go through time it could of course be recorded as the past in the 4rth dimension but how would it predict the future. And, how could there be a past if everything is moving towards the future than the past and future must be an abyss and only the present can contain matter.Please forgive me of any typos and please correct me if I have a misconception on how the string theory works. Thankyou.

There are circumstances in which this essentially happens. Gravitational fields seems to affect the 'speed' of time to a small degree. Hence, if you have a clock on Earth, and another clock far away from the gravitational field of Earth, the one on earth will go slightly slightly slower.You can't use this to go backward in time, though. Traveling in time just like you do in space probably isn't possible, because it would cause a lot of paradoxes.

As far as I've understood it, there is something about the way the universe is made up which would mean strings work like this. Note that strings wouldn't directly make different types of atoms. There's smaller stuff than that. But yes, essentially, following some sort of yet undetermined pattern, a certain vibration would show up as a particle, while another type of vibration would show up as something else. It will probably take quite a while to find out everything about this, and if it's a good model or not.

We already have a limited ability to do this. For example, hydrogen bombs work by taking turning hydrogen into helium. Of course, this isn't exactly easy to do and it can't be done just whenever you want. It usually requires a lot of energy to start.The rest of the questions are just too vague for me to answer. String theory and time travel and such is rather heavy stuff and most of it is just ideas at this point.

Lots and lots of questions in one post there. No. However, theoretically speaking, if you get on a spaceship and slow down relative to earth, earth's time will seem slower according to your reference and your time will appear to go faster according to earth's reference. The moment anyone can answer that question, that person will probably get a nobel prize. Scratch that. Make it a super duper nobel prize.The truth of the matter is not a single person on the planet knows what the extra dimensions look like. People can describe them in terms of math, but that's as far as anyone can get. You just described a paradox. There are various postulated theories on time travel out there, but that's all they are right now, postulated theories. If a string vibrates really fast, then it has a lot of enegy, making it representing a heavier element.You are wrong. It is not a little more complex than that. It's a lot more complex than that. In fact, only a hand-full of people in the world that claim they really know about this subject. Theoretically, if the string's frequency of vibration represents its energy, you would have to either take away the energy or put in some more. The ladder would probably result in something similar to what they did to Hiroshima and Nagasaki in 1945. Actually, according to a recent explanation I heard from a local physicist, if you can't put your hand in the rip. If you extend your hand toward the rip, your hand would end up being on the other side of the rip. Huh? Tell you what, why don't you spend 50 grand to put yourself in cryogenic suspension. Instruct the cryo company to "wake" you when they finally can answer that question. It's quite simple to go into the future. Just count from 1 to 3 and VOILA! You are now in the future.If you are talking about a distant future, it is also relatively simple. Get on a spaceship and accelerate to near the speed of light and remain at that speed for about half an hour. Depending on the relative speed of your spaceship, you could literally end up a million years from the moment you left earth about half an hour ago.What I just described is called time dilation. The faster you travel toward the speed of light, the slower your time will go by relative to the rest of the universe. This is a now confirmed fact by both observation and experimentation. That sounds like a good science fiction plot. You are forgiven

What I meant by them seeing your innerds is if your hand is 2 miles away but the rest of you is there. Will we be able to see the part of your rist that is facing the rip. If so wouldn't it be frigting to observe the inside of there rist. Or would we be unable to see through the rip and therefore can't face a fright like this?

No, that can't really happen. If the hand goes through the hole, then any light would also go through the hole. Hence, if you look from the other side, either you'd see what's on the other side of the other hole, or you'd just see something pitch black.It's a bit hard to explain without making a picture...

So we have no reason to worry about scaring ourselves with fooling around with space/time?

You don't understand. Theoretically, if there is a rip in the fabric of space, we as 3-D creatures won't be able to see it or tell any difference. If you stick your hand into the rip, nothing will happen because your hand will simply come out on the other side of the rip. But we are 3-D creatures, so to us there is no rip in space.So far, we can only see how a rip in space is possible in the calculations. However, noone has yet to propose a way to actually detect such a phenomenon. Since every known scientific method to detects phenomena is based on 3-D, noone knows, or even have an idea, to how we can use our instruments to detect something that is beyond the 3-D space.

I understand fully now. So there could actualy be a rip between you as your typing right now and you could never know because everything that goes through it appears on the other side witch include sound, light and etc. This means you can't see it because you would just see through it. Doesn't that mean that if you rip a hole from here to mars that the two planets would suddenly be right next to each other?What keeps rips from causing the universe to experience some real problems?

Will we one day be able jump from one planet to the other without ships by using rips but then won't that cause the two to colide since everything that is bound by space and time goes right to the other side of it the two planets would be right next to each other so wouldn't they colide?Are strings made up of smaller particles or are they the limit?Can we see strings since they are smaller then atoms and protons and junk? That must mean that they can make up photons but how would the light be able to bounce of a string. Arent some things in a full atom required to protect things from going right through it?How is time warped due to gravity? Can't it have something to do with the 4rth demension of time. I figured since gravitons can travel through other demensions that they effect the 4rth demension and maybe that could be it. Maybe I don't no what I am talking about.Why can't god exist outside of time? People argue that time is not a physical place. But it is a demension so it must be a place in it's own way. Besides god is not bound by our physical laws. Infact, he created them.Now that I think about it? How can there be a rip when a rip would be 3-D. A rip does not exist in the fabric of Space/Time so how can it in itself be 3-Dimensional. How can we know for sure it could be ripped if we cannot detect it?

I got sum theories floating round in this site mostly questions no one could answer so i just thought about it some more and answered them my self...didn't get much in the way of feed back cos as far as i can tell it's all speculative so no one can really say whether it's valid or not and all it did was open up more topics for questioningjust like it's doing for youFrom what i gathered it helps you if you know what you are talking about but it might help others if you dont

Don't know. Don't care.

Anything is possible, I guess. According to the string theory, the string is the limit. There are 2 ways to detect something and one way to probe it. In order to detect something, you either have to physically probe it or examine its trail.In order to probe something, you must use something smaller than the thing you are probing. For example, if I want to probe your hand, I would have to use my finger to detect the physical details of your hand. If I use my head or my arm, I can only tell that something is there but I can't really probe your hand.Subatomic particles are smaller than photons and can't be probed directly as I described above. Rather, we can detect them by examining their trails. The apparatus that are used by scientists today to do this is called a cloud chamber. You can do a google search on this to read more about it.However, strings are thought to be even much smaller than any subatomic particle we know. In fact, it's so small that the cloud chamber is useless. Did you get that idea from a science fiction novel?Gravity doesn't warp time. Matter does. The more mass a matter has, the more space-time it warps. I'm an atheist. Perhaps someone else can answer this one. Imagine that space is 2 dimensional. Think of space as a piece of cloth. If you poke a hole in it, you have a rip in space. If you are a 2 dimensional being (you must read Flatland by Edwin Abbott to understand what I am saying) technically you can't detect the rip at all, since you can't look up or down. So, technically the rip doesn't exist for you.Now, apply that to 3 dimensional space. Technically, if there is a rip, we wouldn't be able to detect it at all.Edited to change "a" to "an" before a vowel. I can't %$#$&%^# believe I actually made that mistake!This message has been edited by Lam, 07-22-2004 11:57 PM

According to Catholic teaching God transends time. Not that he can not exist outside of time.(If one is so inclined to believe such a entity exist.) Time is a manifestation of space. The only reason for time is so that everything does not happen all at once.

"One is punished most for ones virtues" Fredrick Neitzche

I think the highest number of dimensions we can imagine is 5.3-D space plus density plus time.density may be hard to imagine, but think of it like temperature. If you have a pool full of unevenly heated liquid and you wanted to know the location and temperature and time of that liquid you would have five dimensions at one point. (x,y,z,t,temp) You could plot all of this at once on a graph for any fixed value of t (give the point a color for temperature).However, I've read that string dimensions may be curled up inside themselves, but this uses a word "curl" which we only understand in our 3-D. It certainly stretches the brain to imagine what we would "see" if we could perceive all 10 or 11 or more dimensions. I think they've done this with a photon. What fills in the gap? I don't know bout that, but if we could somehow raise the planck constant and keep all of our atoms the same "size" and intact I bet we could walk through walls and disappear and appear at will wherever we wanted too. We can't. We can only make the future take a lot longer to come to us than the rest of the world, so it seems as though we've traveled into the future. The only way we know the past exists or existed is from memory. And if God has a good memory and good foreknowledge, then there must be a past and there must be a future.However, God exists outside of time so past/future/present are all one in the same and exist because he exists.
