我们的宇宙有所谓的边界或者是外面吗，外面是什么

其大无外，其小无内。

大、大、大…我仍然还在大，银河系在我眼中渐渐缩小，我看到了更多更多的星云，越来越多，多到算不完，也数不尽…我仍然在变大...一直在变大...。不知过了多久...正当我倘佯在此奥妙奇特景象时，突然间，我发觉我无法变大了，我，我…我似乎摸到了一层壁，我张开双手上下触摸着，是一层圆形状的膜把我包围着，让我无法再变大，我心中想着，这…这是什么？？霎那间我明了了，原来宇宙不是无边无际，是有边际的！我展开双手摸着宇宙的边，心中静静感受着，感受着这一切。噫！宇宙在动!?宇宙在微微的一小一大、一大一小，好似呼吸，在一小一大间不断的微微在膨胀，啊！宇宙还在变大中!!!这是一个惊人的事实，在此刻没人比我还要惊讶！还要清楚与明白！突然，我发觉我又开始在变大，此时，宇宙对开始在变大的我也做出了回应，更紧紧的包住我，不让我变大，好似不愿让我脱离一般。我感到内在湧出了一股更大的力量，不断的跟宇宙紧箍的力量相抗衡着，一来一去，一去一来，相持不下...
突然间，『啵』的一声，我撑破了宇宙，我挣脱了宇宙的束缚！有[光]，好亮的白光，这[光]是什么？还来不及去细想这问题时，我身在宇宙之外，看着宇宙，好神奇，宇宙就像一个黑色的大圆体，在宇宙之外全是纯白无瑕的光，光被宇宙的胞膜给阻挡，竟然进不去，就像是两个截然不同次元的时空一般。因为我还在变大，所以慢慢的、慢慢的，宇宙在我面前渐渐的缩小，此时，更讶异的景象出现了，在我们身处的宇宙之外，出现了好多好多的宇宙，无穷无尽的延伸，数量多到数不完，我被这景象吓到，心中讶异的喊着：「宇宙...不只一个！」
我还在变大，所有的宇宙都在变小中，渐渐的，所有的宇宙变的更小，小到像沙子一般，小到像灰尘一般，小到我已看不到，噫，我也不再变大了。我抬头看看四周，眼中望去都是光，这光好舒服、好温暖，好熟悉又怀念的感觉。突然间，我意识到[有人]，有[人]在旁边，不只一个，是好几个，我看不清楚他们，因为他们都发出好强好亮的光芒，我无法直视、无法看清楚他们，但我很清楚的看到(感觉到)，他们发出一阵鼓譟，不，不是鼓譟，是类似鼓掌的感觉，是欢迎的感觉，是鼓励的感觉；此时，有一位靠近过来，我瞬间觉得好热好热，[祂]感觉到了，[祂]把光度降低，嗯，祂将能量(震动)降低，更靠近了些，我看着祂，我仔细的端详祂，我终于看清楚了，好熟好熟的感觉，我认识祂，只是我一时想不起来...祂温暖又慈祥的看着我，眼神中满是鼓励，还是那么熟悉的感觉！突然，祂眼神向上看去，我顺着祂也一起抬起头向上望去，那、那、那、那是什么？
好热、好强、好亮，难以置信竟有这么强的光芒，我光是看着就已快融化，全身止不住的无法承受这光芒，这也真的是太强的能量吧！祂要我向上而去，进入那里面，我不断的摇头、不断的告诉祂我做不到。此时，我感觉到周遭更多的[人]靠了过来，祂们一齐发出了更多的[爱][温暖]及[关怀]鼓励着我，要我上去进入那里面，我被祂们的能量拥簇着，全都希望我进入那[光]。那，[好吧！]，我心念一动，突然我开始缓缓的上昇，慢慢的向上靠近那光芒，此时心中(内心深处)也不断的湧出能量，全身发出更高、震动着更大的能量，不断的上昇，不断的靠近，但，我真的受不了，太强了，太热了(说热也难以形容，只是太...很难以文字表达)，太震撼了，我，我，我，我真的无法承受，我，我，我，我受不了了，我靠的越来越近，我好似真的开始融化了，不，我真的在熔化，我，我，我，我进入了，好强、好亮、好...我，我，我......
不知过了多久多久，我醒了过来，我还在台中的家里，还在我的房间里，我感觉到全身泛着不断跳动的光芒，身体是那么的轻盈，好似快要腾空一般，内心又是那么的圆满、自在与祥和。这感觉真舒服，这一段经历太震撼了！长久以来，我一直将它放在心里，只有两三好友知道，今天将这段特殊又宝贵的经历，放在这里，分享给大家，祝有心的人早日[忆起]，回归生命本源！

楼主的这个问题，至今所看到的几种沟通资料中都提到的一点是：似乎没有生命能够探知到宇宙的边界，或者说，身为生命无法理解宇宙的无限性。
这个结论在巴夏的沟通中出现过类似的，就是被问及宇宙中有多少恒星大概，巴夏的回答是“哦上帝啊，我们不知道”，巴夏这个回答其实是在概叹自己种族的智慧在宇宙面前的渺小。
此外其他的此类沟通资料中，比如一的法则也是如此描述：可以假设宇宙是无限的，虽然它尚未被证明或反证。........
还有楼主你得理解一个问题：对于宇宙来说，所谓内外完全没有意义，因为内外本身就暗示着“多余的空间”或是“尚未包含的空间”。然而，宇宙的定义本身就是时间和空间的全集合，也就是说，只要是【存在】，皆被视为宇宙的一部分。无论是多维宇宙，平行宇宙，其他次元都在这个概念之内，坦白的说，宇宙似乎只能是无限的。

这么巧，我前几天才回答美国网友的这个问题。

Here is his answer:
Q: How would you define the big bang theory?
B: In this way, it is simply your physiological interpretation of a particular manifestation of one physiological universe, created out of the initial dynamic tensor fields, within the primal energy field of All That Is. It can be recognized as the creation of time/space itself, in this particular vibrational frequency.
I can quote what he said about universe/big bang/space-time as best as I can.
There are some concepts requiring clarification in his answer.It starts from the concept of geometry of the universe .
Bashar said such words as below.
Q: I just got my question answered so I will switch. could you... from earlier could you check... I have just worked out mathematics of universes and could you check and see how close I am on...
B: Mathematics of universes? (Yes) Well first of all our civilization doesn't necessarily handle mathematics exactly the same way than yours dose.
Q: Don't worry. I don't either.
B: Alright, we will give you our understanding of the idea of what you might call the geometry of the universe if you wish.
Q: You are right it is geometries.
B: Yes. Our expression would be what we call the prime radium. This idea can be explained by analogy by the following illustration. Understanding of course that this is simply an analogous illustration.
Q: If you give me a picture I'll look at it.
B: The picture is this; imagine a completely infinite empty black void, have you got that? (Easy) Now imagine a single subatomic particle in the void and that's all there is. (okay) have you got that? (No problem) Alright, now because there is nothing else but this single subatomic particle, no laws applied to it. If it wants to it can move at infinite speed. Therefore you will understand that if it can move in infinite speed, it can be anywhere and in fact can be everywhere within the entirety of the infinite void all at once.
So if it traces a certain geometric crystalline like pattern overlapping its own path again and again and again in certain ways, where it overlaps the least will be what you consider to be empty space, where overlaps the most will be the densification of matter.
But the idea is that this creates all parallel realities, all time frames, and all dimensions of experience. This one single particle appears next to itself so quickly you think it’s two particles, you think it's three particles, you think it's 4, 5, 6... a billion, a trillion, a quadrillion particles. But it’s all the same particle. Every single one of you, every single one of us, every single star, every single planet, every single chair, every single tree is made up literally not the same kind of particle literally the same one particle (okay) in the ultimate time sharing event.

What's more about this prime radiant.
Prime Radiant
RJ: I recently discovered the idea know as tachyons.
B: Yes.
Q: Can you give us, from your perspective, the relationship of the breaking down of the different energies that are involved in this paradigm? The paradigm that I’ve been looking at has the tachyon at the 7th level and then it breaks it down into different segments from there, with the 8th being sort of an overall void; the idea of being out of the whole concept itself. Is there some kind of order of solidification that you can give us in the sense of energy, in the way...
B: Yes! This has again, directly to do with the relationship between the etheric level and what you call your physical / material level. This relationship, again, is a matter of degree, a matter of frequency, but it is all based on the concept of the Prime Radiant. You have heard us discuss the concept of the Prime Radiant?
Q: I’m not exactly sure what you mean by that.
B: All right. Prime Radiant is the understanding that everything…now, we’ll have to use the terminology that you understand in your language -- particle, you understand, subatomic particle? Yes, you understand these terms?
Q: Yes.
B: It is not really a particle as you think of these things and your scientists know that. But to use the term just to illustrate the point, let us just speak of a Prime Particle, a subatomic particle out of which everything is made in physical/material reality. You follow me so far?
Q: Yes.
B: The idea of the Prime Radiant is that everything that you understand to be an infinite number of particles is actually the same one particle interacting with itself in the following way: just imagine now that you have one particle, just imagine it in your mind’s eye, just for the purpose of illustrating the point. Even though we understand this is not absolutely, literally representative of the reality, just now imagine one particle, one little tiny point, dot, if you wish. And, imagine that this particle can move at infinite speed. Now what this would mean is is that this particle, in being able to move at infinite speed, would be everywhere at once. It would not be perceived as moving, it would just be perceived as being EVERYWHERE.
But let us start with the idea that this particle really has no substance, in your terminology; it is not perceivable, per se, and can only be perceived by you in your physical reality when it reinforces itself by overlapping itself in the path that it takes, in moving in infinite speed and tracing a line of particular geometric pattern over and over and over and over again, with slight variation. Here and there it will cross itself, and as it crosses itself over and over again it will reinforce itself and thus appear to be more and more and more solid. The less it crosses itself the less solid it will appear. This gives rise to the idea of the very densest physical reality, where the particle crosses itself as many times as it possibly can, through the higher more rarified etheric realms where it does not cross it’s own path that many times, to the void in space where it contains, what you call, virtual particles which simply come into existence briefly and flicker out. But you know that the void is contained and is full of many, many different potential particles, potential realities, potential dimensionalities and so forth, and then on up the scale.
The idea simply is that this particle, in moving at infinite speed and being everywhere at once, means that it is interacting with itself. What you perceive to be this particle here, and that particle there, held together by an apparent force, be it a strong force or the electric force or gravity or whatever you which to call it, it is not really being held together by a force, it is not really being attracted to any thing. Gravitation, in that sense, is not an attracted force, there really are no forces, per se, as your society thinks of them.
As such the idea is that when this particle is moving at infinite speed, being everywhere at once, it appears next to itself a number of times and you think, from your perspective, that this is one particle, that is another particle, but it is the same particle interacting with itself, in a sense. And the force that apparently draws them together is simply the geometry of the path that it is taking in that this particle here and this particle there are simply representative of where the lines of that path cross each other, very close to each other. And thus, there is no other place that those particles can be at that moment but next to each other. But it is because of the description of the geometry of the path that they are taking, not because there is actually a force interacting between them. You follow me so far?
Q: Yes.
B: Now, the concept again of this applying to tachyon energy or what your society has labeled tachyons, is that simply in the entire array of geometric patterns that this one particle is taking, you have overlaps and arrays of different kinds of radiating pattern side effects. If you were to imagine a very complicated geometric pattern, you would see that there are many places that the lines cross over and over and over and over and over again, and where they cross as if you have, lets say a spiral going this way and a spiral going that way. You would see certain points where lines cross, and it would appear to your eye that there was a line being described by where those points cross, but it would be in your terms an illusion. You understand?
Q: Yes.
B: There would not really be a line there, but where the points cross, in the succession in which they cross, would give the semblance of the illusion of a path. One of those paths would be called the speed of light. One of those paths would be called the tachyon existence, the tachyon dimension, and all other dimensions and all other levels therein, all within the infinite speed of the Prime Radiant, the Prime Particle.
So it is simply a matter of degree and of tachyons representing the etheric manifestation, the almost mass-less manifestation on the other side of what you call the speed of light. Which is simply one of those lines describing the border of your particular physiological universe, the tachyon being the material of the etheric universe, so to speak. Not having been crystallized, not having been overlapping enough in the geometric pattern to be physicalized, per se, but forming, nonetheless, the underling template for physical reality where those lines all cross sufficiently. Thus going from the tachyon level to the physical level, what you call physical matter, from etheric matter and all the other higher forms of matter of the Prime Radiant, expressions of the Prime Radiant, of light, of energy and so on and so forth.
So all those ideas: light and energy, and matter and tachyons, and etheric reality are all different forms, different expressions of the one Prime Radiant just by virtue of the fact of how many times it interacts or reflects with itself. Does that make some sense to you?
Q: Yes, I understand the Prime Radiant now.

Now it comes to the concept why the universe is expanding.
Since the lines cross each other the most,is what you call the crystallization energy down into matter.The idea is that the relationship of those node points is gravity.The node points are reflective of the matrix in which the material exists and you will understand how to stretch and bend those node points according to certain geometric pattern such as Fibonacci spirals,so the spirals and how they overlap and create overlapping node points cross each other again and again in certain ways,and expand in certain ways.you will understand everything you need to know about the idea of gravity,dark matter,dark energy.That's why our physical universe seems to be accelerating instead of slowing down.
Then it comes to space/time origin created by big bang.
Space-Time Origin Points
Q: I’m interested in the origin of the Universe as we perceive it, and I’d like to know if there are other parallel universes?
B: Yes, there are.
Q: How did our’s come about? Could you elaborate on this?
B: In much the same way that any of what you would call a parallel universe may have come about. Now there are many ways to interpret the idea of the so called coming about of a universe, for really the concept of a universe “coming about” is a perception possible only from within the universe that has come about. The universe, in that sense, existence, in and of itself, did not come about, existence always is. You follow me so far?
Q: Yes.
B: However, within the concept of existence, which always is, there can be the perceptual experience of a discreet interpretation of All That Is, that would appear to have a beginning and an ending, but this is a cycle within existence, it is not really a beginning of existence itself. In that terminology and from that perspective, you can understand that your universe and any similar parallel reality universes came about, so to speak, when an aspect of All That Is reflected itself. Which then allowed that aspect when realized, when self-recognized, to expand, so to speak, from an infinitesimal point, as you understand the concept in space-time, to an expanded interactive version of that self-recognition.
Now that point still exists, everything in your reality is still taking place, and again we apologize for the semantic terminology we must translate this into, because we know it can be confusing...everything that you know in your apparent expanded universe is still actually only taking place within that infinitesimal non-dimensional point. But because this particular infinitesimal non-dimensional point is interacting with itself within the concept of space-time, then all the interactions that take place within that infinitesimal non-dimensional point appear to have the quality that you call volume, distance, dimensionality, “temporariness,” and so forth.
So the universe came about, simply came about, simply from the recognition of All That Is that it could experience itself in this way. And thus, it was automatically realized, because anything that is imagined within the consciousness of All That Is becomes a reality, because that is the nature of All That Is. Does this make any sense to you so far?
Q: Yes.
B: We do not necessarily mean to be ambiguous in your terminology and, of course, there is always the attendant explanation from what we would call the physiochemical point of view, that goes along with the metaphysical concept or explanation, it’s all just about the same thing no matter what terminology you use to describe it.
Q: It is crystal clear to me.
B: All right. Thank you.
