Quotes About Existence

Why does the universe go to all the bother of existing? Is the unified theory so compelling that it brings about its own existence? Or does it need a creator, and, if so, does he have any other effect on the universe? And who created him?

One could still imagine that God, created the universe at the instant of the big bang, or even afterwards in just such a way as to make it look as though there had been a big bang, but it would be meaningless to suppose that it was created before the big bang. An expanding universe does not preclude a creator, but it does place limits on when he might have carried out his job!

The present evidence therefore suggests that the universe will probably expand forever, but all we can really be sure of is that even if the universe is going to recollapse, it won't do so for at least another ten thousand million years, since it has already been expanding for at least that long. This should not unduly worry us: by that time, unless we have colonized beyond the solar system, mankind will long since have died out, extinguished along with our sun!

Anthropic principle: We see the universe the way it is because if it were different we would not be here to observe it. Antiparticle:

Bodies such as stars or black holes cannot just appear out of nothing. But a whole universe can.

When you look at the vast size of the universe, and how insignificant and accidental human life is in it, that seems most implausible.

What place, then, for a creator?

Why do we remember the past but not the future? The

why it is that we and the universe exist. If we find the answer to that, it would be the ultimate triumph of human reason – for then we would know the mind of God.

In fact, according to quantum physics, each particle has some probability of being found anywhere in the universe.

If one believed that the universe had a beginning, the obvious question was what happened before the beginning? What was God doing before He made the world? Was He preparing Hell for people who asked such questions?

God not only plays dice, He also sometimes throw the dice where they cannot be seen.

If we do discover a complete theory, it should in time be understandable in broad principle by everyone, not just a few scientists. Then we shall all, philosophers, scientists, and just ordinary people, be able to take part in the discussion of the question of why it is that we and the universe exist. If we find the answer to that, it would be the ultimate triumph of human reason—for then we would know the mind of God.

One could define God as the embodiment of the laws of nature.

To understand the universe at the deepest level, we need to know not only how the universe behaves, but why. Why is there something rather than nothing? Why do we exist? Why this particular set of laws and not some other?" "This is the Ultimate Question of Life, the Universe, and Everything. We shall attempt to answer it in this book. Unlike the answer given in The Hitchhiker's Guide to the Galaxy, ours won't be simply "42.

Since we know the universe itself was once very small—perhaps smaller than a proton—this means something quite remarkable. It means the universe itself, in all its mind-boggling vastness and complexity, could simply have popped into existence without violating the known laws of nature. From that moment on, vast amounts of energy were released as space itself expanded—a place to store all the negative energy needed to balance the books.

Sin embargo, si descubrimos una teoría completa, debería en su momento ser comprensible en sus líneas generales por todos, no solo por unos pocos científicos. Entonces todos seremos capaces de tomar parte en la discusión de por qué el universo existe. Si encontramos la respuesta a ello, sería el triunfo definitivo de la razón humana, pues entonces conoceríamos la mente de Dios.

Our very existence imposes rules determining from where and at what time it is possible for us to observe the universe. That is, the fact of our being restricts the characteristics of the kind of environment in which we find ourselves. That principle is called the weak anthropic principle.

So the total energy of the universe is zero.

why we should be in the expanding phase rather than the contracting phase? One can answer this on the basis of the weak anthropic principle. Conditions in the contracting phase would not be suitable for the existence of intelligent beings who could ask the question: why is disorder increasing in the same direction of time as that in which the universe is expanding?

Our universe and its laws appear to have a design that both is tailor-made to support us and, if we are to exist, leaves little room for alteration. That is not easily explained, and raises the natural question of why it is that way.

Why is there something rather than nothing? Why do we exist? Why this particular set of laws and not some other? This is the Ultimate Question of Life, the Universe, and Everything. We shall attempt to answer it in this book. Unlike the answer given in The Hitchhiker's Guide to the Galaxy, ours won't be simply "42."  

There is no picture- or theory-independent concept of reality.

calculations show that a change of as little as 0.5 percent in the strength of the strong nuclear force, or 4 percent in the electric force, would destroy either nearly all carbon or all oxygen in every star, and hence the possibility of life as we know it. Change those rules of our universe just a bit, and the conditions for our existence disappear!
