Eighthly, none of our sense-perceptions is opposed to the acceptance of infinity, since we cannot deny infinity merely because we do not sensibly perceive it; but since sense in itself is included in infinity, and since reason doth confirm infinity, therefore needs must that we posit infinity. Moreover, if we consider well, sense doth present to us an infinite universe. For we perceive an endless series of objects, each one contained by another, nor do we ever perceive either with our external or our internal sense, an object which is not contained by another or similar object.

Lastly before our eyes one thing is seen to bound another; air is as a well between the hills, and mountains between tracts of air, land bounds the sea and again sea bounds all lands; yet in truth there is nothing outside to limit the universe ... so far on every side spreads out huge room for things, free from limit in all directions everywhere. [6]

From the testimony of our sight then we should rather infer the infinite, since there is no object which doth not terminate in another, nor can we experience aught which terminateth in itself.

Because our entire universe is made up of consciousness, we never really experience the universe directly we just experience our consciousness of the universe, our perception of it, so right, our only universe is perception.

Infinity and eternity are the limits of imagination. You can project your imagination into the past or into the future; you can destroy an old image that has troubled you or create a new one that will rejoice you.

The universe has a finite velocity which limits not only the spread of its events, but also the speed of our perceptions. The moment of actuality slips too fast by the slow, coarse net of our senses.

if you perceive the universe as being a universe of abundance, then it will be. If you think of the universe as one of scarcity, then it will be.

Now, almost one hundred years later, it is difficult to fully appreciate how much our picture of the universe has changed in the span of a single human lifetime.

As far as the scientific community in 1917 was concerned, the universe was static and eternal, and consisted of a one single galaxy, our Milky Way, surrounded by vast, infinite, dark, and empty space.

This is, after all, what you would guess by looking up at the night sky with your eyes, or with a small telescope, and at the time there was little reason to suspect otherwise.

"The Hitchhiker's Guide to the Galaxy's definition of "Universe":

The Universe is a very big thing that contains a great number of planets and a great number of beings. It is Everything. What we live in. All around us. The lot. Not nothing. It is quite difficult to actually define what the Universe means, but fortunately the Guide doesn't worry about that and just gives us some useful information to live in it.

Area: The area of the Universe is infinite.

Imports: None. This is a by product of infinity; it is impossible to import things into something that has infinite volume because by definition there is no outside to import things from.

Exports: None, for similar reasons as imports.

Population: None. Although you might see people from time to time, they are most likely products of your imagination. Simple mathematics tells us that the population of the Universe must be zero. Why? Well given that the volume of the universe is infinite there must be an infinite number of worlds. But not all of them are populated; therefore only a finite number are. Any finite number divided by infinity is zero, therefore the average population of the Universe is zero, and so the total population must be zero.

Art: None. Because the function of art is to hold a mirror up to nature there can be no art because the Universe is infinite which means there simply isn't a mirror big enough.

Sex: None. Although in fact there is quite a lot, given the zero population of the Universe there can in fact be no beings to have sex, and therefore no sex happens in the Universe."

The Universe, the whole infinite Universe. The infinite suns, the infinite distances between them, and yourself an invisible dot on an invisible dot, infinitely small.

[T]heoretical researches of Einstein and Weyl make it probable that the space which remains beyond is not illimitable; not merely the material universe, but also space itself, is perhaps finite...

Space is as infinite as we can imagine, and expanding this perspective is what adjusts humankind’s focus onto conquering our true enemies, the formidable foes: ignorance and limitation.

The sky is NOT the limit. Beyond the universe is.

We know by actual observation only a comparatively small part of the whole universe. I will call this "our neighborhood." Even within the confines of this province our knowledge decreases very rapidly as we get away from our own particular position in space and time. It is only within the solar system that our empirical knowledge extends to the second order of small quantities (and that only for g₄₄ and not for the other g_αβ), the first order corresponding to about 10^-8. How the g_αβ outside our neighborhood are, we do not know, and how they are at infinity of space or time we shall never know. Infinity is not a physical but a mathematical concept, introduced to make our equations more symmetrical and elegant. From the physical point of view everything that is outside our neighborhood is pure extrapolation, and we are entirely free to make this extrapolation as we please to suit our philosophical or aesthetical predilections—or prejudices. It is true that some of these prejudices are so deeply rooted that we can hardly avoid believing them to be above any possible suspicion of doubt, but this belief is not founded on any physical basis. One of these convictions, on which extrapolation is naturally based, is that the particular part of the universe where we happen to be, is in no way exceptional or privileged; in other words, that the universe, when considered on a large enough scale, is isotropic and homogeneous.

It agitates me that the skyline there is forever our limit, I long for the power of unlimited vision...If I could behold all I imagine.

A million million million million (1 with twenty-four zeros after it) miles, the size of the observable universe.
