A Quote by Lisa Randall
There could be more to the universe than the three dimensions we are familiar with. They are hidden from us in some way, perhaps because they're tiny or warped. But even if they're invisible, they could affect what we actually observe in the universe.

We are part of this universe; we are in this universe, but perhaps more important than both of those facts, is that the universe is in us.
Any possible universe could be explained as the work of some sort of designer. Even a universe that is completely chaotic...could be supposed to have been designed by an idiot.
We have simply arrived too late in the history of the universe to see this primordial simplicity easily... But although the symmetries are hidden from us, we can sense that they are latent in nature, governing everything about us. That's the most exciting idea I know: that nature is much simpler than it looks. Nothing makes me more hopeful that our generation of human beings may actually hold the key to the universe in our hands - that perhaps in our lifetimes we may be able to tell why all of what we see in this immense universe of galaxies and particles is logically inevitable.
We are all connected to each other biologically, to the earth chemically and to the rest of the universe atomically. That's kinda cool! That makes me smile and I actually feel quite large at the end of that. It's not that we are better than the universe, we are part of the universe. We are in the universe and the universe is in us.
We live inside our universe and cannot get a bird's-eye view of it from outside. And we cannot even see all of our universe. Distant parts of it are expanding away from us so fast that they are invisible; they go faster than the speed of light. Having bigger telescopes to see fainter stars will not help us here: invisible is truly invisible.
There are dimensions of power, there are dimensions of knowledge, and there are dimensions of confusion. The universe is a very, very big place. To think the universe is only composed of the physical universe is to be rather shortsighted.
I often think that we are like the carp swimming contentedly in that pond. We live out our lives in our own "pond," confident that our universe consists of only the familiar and the visible. We smugly refuse to admit that parallel universes or dimensions can exist next to ours, just beyond our grasp. If our scientists invent concepts like forces, it is only because they cannot visualize the invisible vibrations that fill the empty space around us. Some scientists sneer at the mention of higher dimensions because they cannot be conveniently measured in the laboratory.
I look up at the night sky, and I know that, yes, we are part of this Universe, we are in this Universe, but perhaps more important than both of those facts is that the Universe is in us. When I reflect on that fact, I look up — many people feel small, because they’re small and the Universe is big, but I feel big, because my atoms came from those stars.
Since I found that one could make a case shadow from a three-dimensional thing, any object whatsoever - just as the projecting of the sun on the earth makes two dimensions - I thought that by simple intellectual analogy, the fourth dimension could project an object of three dimensions, or, to put it another way, any three-dimensional object, which we see dispassionately, is a projection of something four-dimensional, something we are not familiar with.
In this vast universe, we are condemned to feel tiny; megalomaniac is the one who cannot feel the true dimensions of this universe!
It's not even a question of whether the universe is meaningful or meaningless. It's in what way could it be meaningful, or in what way, if it was meaningful, could that be even more meaningless than normal meaninglessness?
The universe and the Laws of Physics seem to have been specifically designed for us. If any one of about 40 physical qualities had more than slightly different values, life as we know it could not exist: Either atoms would not be stable, or they wouldn't combine into molecules, or the stars wouldn't form heavier elements, or the universe would collapse before life could develop, and so on...
We know there is gravity because apples fall from trees. We can observe gravity in daily life. If we could throw an apple to the edge of the universe, we would observe it accelerating.
In some parallel universe, there was a Gansey who could tell Blue that he found the ten inches of her bare calves far more tantalizing than the thirteen cubic feet of bare skin Orla sported. But in this universe, that was Adam’s job. He was in a terrible mood.
A scenario is suggested by which the universe and its laws could have arisen naturally from nothing. Current cosmology suggests that no laws of physics were violated in bringing the universe into existence. The laws of physics themselves are shown to correspond to what one would expect if the universe appeared from nothing. There is something rather than nothing because something is more stable.
The vault above us is not deaf because the universe is an idiot; the silence is not the heartless silence of an endless and aimless world. Rather the silence around us is a small and pitiful stillness like the prompt stillness of a sick room. We are perhaps permitted tragedy as a sort of merciful comedy, because the frantic energy of divine things would knock us down like a drunken farce. We can take our own tears more lightly than we could take the tremendous levities of the angels. So we sit perhaps in a starry chamber of silence while the laughter of the heavens is too loud for us to hear.
