“The universe has been expanding since the big bang, thus early on it was hot and dense. To trace the history of the universe we must understand the dynamics that operates when the universe was hot and particles were very energetic. Before the standard model we could not go back further than 200,000 years after the big bang. Today, especially since QCD simplifies at high energy, we can extrapolate to very eary times, where nucleons melt and quarks and gluons are liberated to form a quark-gluon plasma.”

“The universe would have expanded in a smooth way from a single point. As it expanded, it would have borrowed energy from the gravitational field, to create matter. As any economist could have predicted, the result of all that borrowing, was inflation. The universe expanded and borrowed at an ever-increasing rate. Fortunately, the debt of gravitational energy will not have to be repaid until the end of the universe.”

Stephen Hawking (1942–2018) British theoretical physicist, cosmologist, and author

The Beginning of Time (1996)

“What the Big Bang theory tells us, is that at least our region of the universe 13.82 years ago, was an extremely hot, dense uniform soup of particles which in the conventional standard Big Bang model filled literally all of space—and now we certainly believe that it filled essentially all of the space that we have access to—uniformly. …This is contrary to a popular cartoon image of the Big Bang, which is just plain wrong. The cartoon image of the Big Bang is the image of a small egg of highly dense matter that then exploded and spewed out into empty space. That is not the scientific picture of the Big Bang. …If there was a small egg that exploded into empty space, you would certainly expect that today you would see something different if you were looking towards where the egg was, versus looking the opposite direction, but we don't see any effect like that. When we look around the sky the universe looks completely uniform, on average, in all directions, to a very high degree of accuracy… So we don't see a sign of an egg having happened anywhere. Rather, the Big Bang seems to have happened everywhere, uniformly.”

“Yes, the universe had a beginning. Yes, the universe continues to evolve. And yes, every one of our body's atoms is traceable to the big bang and to the thermonuclear furnace within high-mass stars. We are not simply in the universe, we are part of it. We are born from it. One might even say we have been empowered by the universe to figure itself out — and we have only just begun.”

“Some people think that the big bang is an explanation of how the universe began, its not. The big bang is a theory of how the universe evolved from a split second after whatever brought it into existence.”

Brian Greene (1963) American physicist

In response to David Letterman's question, "What do we now know [about the universe] we didn’t know before?" on The Late Show (23 March 2005)
Context: Well, a big question is how did the universe begin. And we, cannot answer that question. Some people think that the big bang is an explanation of how the universe began, its not. The big bang is a theory of how the universe evolved from a split second after whatever brought it into existence. And the reason why we’ve been unable to look right back at time zero, to figure out how it really began; is that conflict between Einstein’s ideas of gravity and the laws of quantum physics. So, string theory may be able to — it hasn’t yet; we’re working on it today — feverishly. It may be able to answer the question, how did the universe begin. And I don’t know how it’ll affect your everyday life, but to me, if we really had a sense of how the universe really began, I think that would, really, alert us to our place in the cosmos in a deep way.

“That the universe, as was once thought, expands and contracts indefinitely, one Big Bang collapsing into another one, seemed reasonable enough. But in both models of the universe, what caused the first Big Bang? Or was there a first Big Bang, any more than a last number? If there was a first cause, was there a first causer? Did Big Bangs just happen to happen? Can we name the first causer “God”? We can name it anything we want. I can name it after myself. It is utterly insignificant what it is called, because we would be giving a name to something that falls outside all categories of thought and must be unknowable and irrelevant to knowledge. So naming it is a futile enterprise. The word “God” is unhelpful because it implies it has a knowable definition.”

“…mention is made of evidences in favour of the big bang, like the microwave background. It is a relic radiation supposed to have formed very early after the big bang. As the universe expanded it cooled down and its present temperature is at 2.7 K. The only fact which is measurable or has been measured is that there is a background of 2.7 K temperature. Saying that this is left over from the early universe is a speculation. It is a part of a theoretical structure I am supposed to have built which enables me to say that it is a relic of that early-on era. We have given a different explanation. Helium forms by fusion of hydrogen inside a star like the sun, leading to radiation. One can ask the following question: if all the helium that you find in the universe was formed in stars sometime or the other, how much radiation will be formed and what would its temperature be? The answer is 2.7 K. If you ask a big bang person why his relic radiation today has a temperature of 2.7 K he doesn’t know. This alternative explanation that I’m giving is able to do more than what the big bang does. So I don’t see any reason to say we have a very positive proof of the big bang happening.”

“We should not act like we know that the universe began with the Big Bang… we'll see that there are strong suggestions that the Big Bang was perhaps not really the beginning of existence, but really just the beginning of our local universe, often called a pocket universe.”

“At about the age of six or seven, I realized that of all the invisible powers the one I was destined to be most strongly affected and dominated by was music.”

Hermann Hesse book Gertrud

Source: Gertrude (1910), p. 4
Context: At about the age of six or seven, I realized that of all the invisible powers the one I was destined to be most strongly affected and dominated by was music. From that moment on I had a world of my own, a sanctuary and a heaven that no one could take away from me. Oh, music! A melody occurs to you; you sing it silently, inwardly only; you steep your being in it; it takes possession of all your strength and emotions, and during the time it lives in you, it effaces all that is fortuitous, evil, coarse and sad in you; it brings the world into harmony with you, it makes burdens light and gives wings to to depressed spirits.
