For nothing exists in our mind that could enable us to experience as a reality a space-time continuum of three dimensions which is curved within a further dimension. This outcome of Einstein's endeavours results from the fact that he tried by means of gravity-bound thought to comprehend universal happenings of which the true causes are non-gravitational.

Then he slid open the door and emerged into his own dimension of space-time. Outside was a wide hallway, with a pale green floor, paler green walls, and a ceiling of greenish off-white. A big hole had been cut to accommodate the dome, and across the hallway a desk had been set up, and at it sat a clerk in a pale blue tunic, who was just taking the audio-plugs of a music-box out of his ears.

But the conversion to star-drive, as the Lancet was wrenched, crew and all, out of the normal space-time continuum, was far outside of normal human experience.

"The spatio-temporal displacement field is capable of identifying that spot " Gregory pointed to a ten-foot circle in front of a bank of sleek-cabineted, dial-studded machines " with any set of space-time coordinates in the universe. However, to avoid disruption of the structure of space-time, we must return you to approximately the same point in space-time."

Went out like a snuffed candle, soon as he turned on his drive. Okay, go ahead and build one if you can. But don't bother booking passage for me." "You mean you'd stay behind if I built a hyperspace ship?" "Sure I would." There was no hesitation in Rat's voice. "I like this particular space-time continuum very much.

Altogether, there must have elapsed about 500,000 years from the earliest ape-like human stage of life on this planet to the present time. It necessarily follows that the age of our present civilization is by no means that which the Bible stipulates, but is merely an atom in the vast space-time of this earth.

But I could not be party to such a crime as Hradzka contemplated when it lay within my power to prevent it." "The machine will take him out of our space-time continuum, or back to a time when this planet was a swirling cloud of flaming gas?" Zarvas Pol asked. Kradzy Zago shook his head. "No, the unit is not powerful enough for that. It will only take him about ten thousand years into the past.

Accordingly they express for us the demands of an ideal accuracy, and of an ideal simplicity in the exposition of relations. These event-particles are the ultimate elements of the four-dimensional space-time manifold which the theory of relativity presupposes. You will have observed that each event-particle is as much an instant of time as it is a point of space.

He was crouching, the spherical plastic object in his right hand, his thumb over the button, when the field collapsed. Sure enough, right in front of him, so close that he could smell the very heat of it, was the big tank with the red star on its turret. He cursed the sextet of sanctimonious double-crossers eight thousand miles and fifty years away in space-time.

I have called it an instantaneous point-flash. Thus in the structure of this space-time manifold space is not finally discriminated from time, and the possibility remains open for diverse modes of discrimination according to the diverse circumstances of observers. It is this possibility which makes the fundamental distinction between the new way of conceiving the universe and the old way.
