Let me summarise our delicate position in this universe: Our every word can be our last word; our every look can be our last look! Our every moment can be our last moment! Are we happy about this fragile situation? No! Are we going to deceive ourselves with some childish stories, in other words with religion? No! Then what are we going to do? We will change this desperate situation, we will strike this chaotic universe with human mind, with high intelligence, in short with science! Humanity__ ultimate objective is to reshape this dangerous universe so that no threat will ever remain for our existence!

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.

A Universe from Nothing: Why There Is Something Rather Than Nothing

"

[On the practical applications of particle physics research with the Large Hadron Collider.]Sometimes the public says, 'What's in it for Numero Uno? Am I going to get better television reception? Am I going to get better Internet reception?' Well, in some sense, yeah. ... All the wonders of quantum physics were learned basically from looking at atom-smasher technology. ... But let me let you in on a secret: We physicists are not driven to do this because of better color television. ... That's a spin-off. We do this because we want to understand our role and our place in the universe.

While the Copernican principle comes with no guarantees that it will forever guide us to cosmic truths, it's worked quite well so far: not only is Earth not in the center of the solar system, but the solar system is not in the center of the Milky Way galaxy, the Milky Way galaxy is not in the center of the universe, and it may come to pass that our universe is just one of many that comprise a multiverse. And in case you're one of those people who thinks that the edge may be a special place, we are not at the edge of anything either.

Death by Black Hole - And Other Cosmic Quandaries

"

You would hardly think, at first, that horrid monsters lie up there waiting to be discovered by any moderately penetrating mind--monsters to which those of the oceans bear no sort of comparison."What monsters may they be?"Impersonal monsters, namely, Immensities. Until a person has thought out the stars and their inter-spaces, he has hardly learnt that there are things much more terrible than monsters of shape, namely, monsters of magnitude without known shape. Such monsters are the voids and waste places of the sky... In these our sight plunges quite beyond any twinkler we have yet visited. Those deep wells for the human mind to let itself down into, leave alone the human body! and think of the side caverns and secondary abysses to right and left as you pass on!...There is a size at which dignity begins," he exclaimed; "further on there is a size at which grandeur begins; further on there is a size at which solemnity begins; further on, a size at which awfulness begins; further on, a size at which ghastliness begins. That size faintly approaches the size of the stellar universe. So am I not right in saying that those minds who exert their imaginative powers to bury themselves in the depths of that universe merely strain their faculties to gain a new horror?

"

I have not yet lost a feeling of wonder, and of delight, that this delicate motion should reside in all the things around us, revealing itself only to him who looks for it. I remember, in the winter of our first experiments, just seven years ago, looking on snow with new eyes. There the snow lay around my doorstep _ great heaps of protons quietly precessing in the earth's magnetic field. To see the world for a moment as something rich and strange is the private reward of many a discovery.

Current theories on the creation of the Universe state that, if it were created at all and didn't just start, as it were, unofficially, it came to being between ten and twenty thousand million years ago. By the same token the earth itself is generally supposed to be about four and a half thousand million years old.These dates are incorrect.Medieval Jewish scholars put the date of the Creation at 3760BC. Greek Orthodox theologians put Creation as far back as 5508BC.These suggestions are also incorrect.Archbishop James Usher (1580-1656) published Annales Veteris et Novi Testamenti in 1654, which suggested that the Heaven and the Earth were created in 4004BC. One of his aides took the calculation further, and was able to announce triumphantly that the Earth was created on Sunday the 21st of October, 4004BC, at exactly 9.00 a.m., because God liked to get work done early in the morning while he was feeling fresh.This too was incorrect. By almost a quarter of an hour.The whole business with the fossilized dinosaur skeletons was a joke the paleontologists haven't seen yet.

There is a philosophy that says that if something is unobservable -- unobservable in principle -- it is not part of science. If there is no way to falsify or confirm a hypothesis, it belongs to the realm of metaphysical speculation, together with astrology and spiritualism. By that standard, most of the universe has no scientific reality -- it's just a figment of our imaginations.

The Black Hole War: My Battle with Stephen Hawking to Make the World Safe for Quantum Mechanics

"

In 5 billion years, the expansion of the universe will have progressed to the point where all other galaxies will have receded beyond detection. Indeed, they will be receding faster than the speed of light, so detection will be impossible. Future civilizations will discover science and all its laws, and never know about other galaxies or the cosmic background radiation. They will inevitably come to the wrong conclusion about the universe......We live in a special time, the only time, where we can observationally verify that we live in a special time.
