Quotes About Curvature

There is nothing in the world except empty curved space. Matter, charge, electromagnetism, and other fields are only manifestations of the bending of space. Physics is geometry.

Matter tells space-time how to curve. Space-time tells matter how to move.

When you head on out to the Moon, in very short order, and you get a chance to look back at the Earth, that horizon slowly curves around in upon himself, and all of sudden you're looking at something that is very strange, but yet is very, very familiar, because you're beginning to see the Earth evolve.

Gravity is neither a force nor a consequence of any space-time curvature. It is simply an orderly spatial illusion to non-spatial observer/s.

the future is unknown and open, so it might well have the curvature required. This would mean that any time travel would be confined to the future. There would be no chance of Captain Kirk and the Starship Enterprise turning up at the present time.

Why do we see only three space dimensions and one time dimension? The suggestion is that the other dimensions are curved up into a space of very small size, something like a million million million million millionth of an inch. This is so small that we just don't notice it: we see only one time dimension and three space dimensions, in which space-time is fairly flat.

The mass of the sun curves space-time in such a way that although the earth follows a straight path in four-dimensional space-time, it appears to us to move along a circular orbit in three-dimensional space.

region of space-time known as a black hole.

AFEW YEARS AGO the city council of Monza, Italy, barred pet owners from keeping goldfish in curved goldfish bowls. The measure's sponsor explained the measure in part by saying that it is cruel to keep a fish in a bowl with curved sides because, gazing out, the fish would have a distorted view of reality.

The twentieth century saw man's view of the universe transformed: we realized the insignificance of our planet in the vastness of the universe, and we discovered that time and space we curved and inseparable , that the universe was expanding, and that it had a beginning in time.

In general relativity, bodies always follow straight lines in four-dimensional space-time, but they nevertheless appear to us to move along curved paths in our three-dimensional space. (This is rather like watching an airplane flying over hilly ground. Although it follows a straight line in three-dimensional space, its shadow follows a curved path on the two-dimensional ground.)

We thus have experimental evidence both that space-time can be warped (from the bending of light during eclipses) and that it can be curved in the way necessary to allow time travel (from the Casimir effect).

If you're in a helicopter, and you hover, why does the Earth not come to you if it's round?

Either it is the fold of the infinite, or the constant folds [replis] of finitude which curve the outside and constitute the inside.

My body is damaged from music in two ways. I have a red irritation in my stomach. It's psychosomatic, caused by all the anger and the screaming. I have scoliosis, where the curvature of your spine is bent, and the weight of my guitar has made it worse. I'm always in pain, and that adds to the anger in our music.

Matter tells space how to curve, space tells matter how to move.

Earth Defense Alliance ships were outfitted with reverse-engineered alien technology, including a Trägheitslosigkeit Field Generator, which created a small inertia-cancellation field around a spacecraft, by "harnessing the aligned spin of gyromagnetic particles to alter the curvature of space-time" or something.

The reason for this is that the universe bends, in a way we can't adequately imagine

We recall that the warping of the bedsheet was determined by the presence of the rock. Einstein summarized this analogy by stating: The presence of matter-energy determines the curvature of the space-time surrounding it.

At rest, we know that its circumference is equal to p times the diameter. Once the merry-go-round is set into motion, however, the outer rim travels faster than the interior and hence, according to relativity, should shrink more than the interior, distorting the shape of the merry-go-round. This means that the circumference has shrunk and is now less than p times the diameter; that is, the surface is no longer flat. Space is curved.

Roughly speaking, the greater the value of the metric tensor, the greater the crumpling of the sheet. No mattet how crumpled the sheet of paper, the metric tensor gives us a simple means of measuring its curvature at any point. If we flattened the crumpled sheet completely, then we would retrieve the formula of Pythagoras.

Finalmente, Einstein creó dos grandes teorías. La primera fue la relatividad especial, que describía las propiedades de los rayos de luz en el espacio-tiempo e introducía una simetría basada en rotaciones en cuatro dimensiones. La segunda fue la relatividad general, en la que la gravedad se revela como la curvatura del espacio-tiempo.

Black holes collect problems faster than they collect matter.

It is now known to science that there are many more dimensions than the classical four. Scientists say that these don't normally impinge on the world because the extra dimensions are very small and curve in on themselves, and that since reality is fractal most of it is tucked inside itself. This means either that the universe is more full of wonders than we can hope to understand or, more probably, that scientists make things up as they go along.
