Quotes About Space

Particle physicists are way ahead of cosmologists. Cosmology has produced one totally mysterious quantity: the energy of empty space, about which we understand virtually nothing. However, particle physics has not understood many more quantities for far longer!

But relying on invisible miracles is the stuff of religion, not science. To ascertain whether this remarkable accident was real, physicists relied on another facet of the quantum world. Associated with every background field is a particle, and if you pick a point in space and hit it hard enough, you may whack out real particles.

Special relativity says nothing can travel through space faster than the speed of light. But space itself can do whatever the heck it wants, at least in general relativity. And as space expands, it can carry distant objects, which are at rest in the space where they are sitting

the shocking revelation that empty space indeed has energy—and enough energy in fact to dominate the expansion of the universe.

The central problem with the notion of creation is that it appears to require some externality, something outside of the system itself, to preexist, in order to create the conditions necessary for the system to come into being. This is usually where the notion of God—some external agency existing separate from space

one's universe would appear very different from the vast bulk of space around it, which would still be inflating. In this picture, inflation is eternal. Some regions, indeed most of space, will go on inflating forever.

the remaining 70 percent of the total energy in the universe resided not in any form of matter, but rather in empty space itself.

It is as if Earth were purposely hung in space, at just the right distance from the Sun, and provided with just the right amount of every element needed for life to exist.

The woman led us into a living room. A decent-sized space. Expensive furniture and rugs. A big TV. No stereo, no books. It all looked a bit halfhearted. Like somebody had spent twenty minutes with a catalog and ten thousand dollars.

Combat is about time and space and opposing forces. Like a huge four-dimensional diagram. First step is to misinform the enemy. Let him think your diagram is a completely different shape. You assume all communications are penetrated, and then you use them to spread lies and deceit. You buy yourself an advantage.

He understood the theory. In an emergency people would have to exit that way, out through the window and over the wing. Hence all kinds of regulations mandated a minimum space, so people would be comfortable on their way through, except that if such a thing existed as a minimum space for a person to be comfortable, then why wasn't every row just as capacious? It was a regulatory conundrum he couldn't unravel.

I remembered Marshall as large and dark and these guys were small, which is much more usual for Armored people. One thing there isn't a lot of inside an Abrams is room.

En el plano estratégico, Gran Bretaña era un portaaviones amarrado de continuo en la costa europea y tenía muchísimo espacio para cubiertas de despegue.

Space and time emerge from the laws rather than providing an arena in which things happen.

if physics is much simpler to describe under the assumption that space is discrete, rather than continuous, is not this fact itself a strong argument for space being discrete? If so, then might space look, on some very small scale, something like Wilson's lattice.

Whatever is happening on very small scales near the horizon of the black hole will be enlarged by the effect whereby the wavelengths of light are stretched as the light climbs up to us. This means that jf we can observe light coming from very close to the horizon of a black hole, we may be able to see the quantum structure of space itself.

Leibniz had a vision of a world in which everything lives not in space but immersed in a network of relationships.

To understand what we mean when we say that space is discrete, we must put our minds completely into the relational way of thinking, and really try to see and feel the world around us as nothing but a network of evolving relationships. These relationships are not among things situated in space - they are among the events that make up the history of the world. The relationships define the space, not the other way around.

You can invoke neither time nor space nor matter not energy nor the laws of nature to explain the origin of the universe. General relativity points to the need for a cause that transcends those domains. ~Stephen C. Meyer, PHD~

Comyn thought it was funny. It was very funny, indeed, that men making the second Big Jump in history, that men going faster and farther than any men but five had ever gone before, separated only by metal walls from the awfulness of infinity, should sit and play games with little plastic cards and pretend they were not where they were.

Today we know that there are other solar systems only tens of light years away. Had the Golden Age continued unabated, we might by now have sent probes exploring them. We might have landed on the moon in the year 969 instead of 1969. We might have an understanding of space and life that is unimaginable to us today. Instead, events occurred that would delay the progress begun by the Greeks by a millennium.

What can you prove about space? How do you know where you are? Can space be curved? How many dimensions are there? How does geometry explain the natural order and unity of the cosmos? These are the questions behind the five geometric revolutions of world history. It started with a little scheme hatched by Pythagoras: to employ mathematics as the abstract system of rules that can model the physical universe.
