Cosmology Quotes

The complex order we now observe [in the universe] could *not* have been the result of any initial design built into the universe at the so-called creation. The universe preserves no record of what went on before the big bang. The Creator, if he existed, left no imprint. Thus he might as well have been nonexistent.

Someday they would discover that the stars were not sacred, but made from the same material as their bodies. They would learn it was the stars that created their worlds, that worlds created their minds, that minds created tools, and tools could create stars. Growing, sprawling, thriving until they too became masters of their own understanding, chasing enlightenment with the fervor of having nothing to lose, launching from their homelands like fireworks with glorious yellow tails.

How can we satisfy ourselves without going on in infinitum? And, after all, what satisfaction is there in that infinite progression? Let us remember the story of the Indian philosopher and his elephant. It was never more applicable than to the present subject. If the material world rests upon a similar ideal world, this ideal world must rest upon some other; and so on, without end. It were better, therefore, never to look beyond the present material world.

Then there is the cosmologist, who views himself as nothing but a manipulation of atoms; his mind configured out of randomness into the tool a vast, blind universe might use to perceive itself. If this is so then truly "all is vanity". What could be more pleasing to the cosmic narcissist than to gaze eternally with a billion eyes into the mirror that is himself? What fault, however, if certain eyes ultimately don’t like what they see?

A world where it is safe to love is a world where it is safe to live

The biblical account of the origin of the cosmos in Genesis, for example, posits that a god created the physical universe particularly with human beings in mind, and so unsurprisingly placed the Earth at the center of creation.Modern cosmological knowledge has refuted such an account. We are living in the golden age of cosmology: More has been discovered about the large-scale structure and history of the visible cosmos in the last 20 years than in the whole of prior human history. We now have precise knowledge of the distribution of galaxies and know that ours is nowhere near the center of the universe, just as we know that our planetary system has no privileged place among the billions of such systems in our galaxy and that Earth is not even at the center of our planetary system. We also know that the Big Bang, the beginning of our universe, occurred about 13.7 billion years ago, whereas Earth didn’t even exist until about 10 billion years

There should be no boundary to human endeavor.

The sky is a meadow of wildstar flowers.

Quantum fluctuations are, at their root, completely a-causal, in the sense that cause and effect and ordering of events in time is not a part of how these fluctuations work. Because of this, there seem not to be any correlations built into these kinds of fluctuations because 'law' as we understand the term requires some kind of cause-and-effect structure to pre-exist. Quantum fluctuations can precede physical law, but it seems that the converse is not true. So in the big bang, the establishment of 'law' came after the event itself, but of course even the concept of time and causality may not have been quite the same back then as they are now.

There are only certain intervals of time when life of any sort is possible in an expanding universe and we can practise astronomy only during that habitable time interval in cosmic history.

My view is that if your philosophy is not unsettled daily then you are blind to all the universe has to offer.

Individual events. Events beyond law. Events so numerous and so uncoordinated that, flaunting their freedom from formula, they yet fabricate firm form.

The bright sun was extinguish'd, and the starsDid wander darkling in the eternal space.

A blade of grass is a commonplace on Earth; it would be a miracle on Mars. Our descendants on Mars will know the value of a patch of green. And if a blade of grass is priceless, what is the value of a human being?

The Age of the Stars had come to an end. Once in a billion years, a feeble supernova illuminated the vestiges of its home; brown dwarfs, neutron stars, blackholes... lifeless echoes of their former majesty.

There is something stunningly narrow about how the Anthropic Principle is phrased. Yes, only certain laws and constants of nature are consistent with our kind of life. But essentially the same laws and constants are required to make a rock. So why not talk about a Universe designed so rocks could one day come to be, and strong and weak Lithic Principles? If stones could philosophize, I imagine Lithic Principles would be at the intellectual frontiers.

For me, it is far better to grasp the Universe as it really is than to persist in delusion, however satisfying and reassuring.

We have yet to encounter an observable astronomical phenomenon that require a supernatural element to be added to a model in order to describe the even...Observations in cosmology look just as they can be expected to look if there is no God.

It took less than an hour to make the atoms, a few hundred million years to make the stars and planets, but five billion years to make man!

The total amount of energy from outside the solar system ever received by all the radio telescopes on the planet Earth is less than the energy of a single snowflake striking the ground.
