Formerly, people thought that if matter disappeared from the universe, space and time would remain. Relativity declares that space and time would disappear with matter.
We can make a similar examination, but with greater uncertainty, of the extraterrestrial hypothesis that holds that a wide range of UFOs viewed on the planet Earth are space vehicles from planets of other stars.
If everything when it occupies an equal space is at rest, and if that which is in locomotion is always occupying such a space at any moment, the flying arrow is therefore motionless.
Once we overcome our fear of being tiny, we find ourselves on the threshold of a vast and awesome Universe that utterly dwarfs — in time, in space, and in potential — the tidy anthropocentric proscenium of our ancestors.
The ordinary adult never gives a thought to space-time problems ... I, on the contrary, developed so slowly that I did not begin to wonder about space and time until I was an adult. I then delved more deeply into the problem than any other adult or child would have done.
We join spokes together in a wheel, but it is the center hole that makes the wagon move. We shape clay into a pot, but it is the emptiness inside that holds whatever we want. We hammer wood for a house, but it is the inner space that makes it livable. We work with being, but non-being is what we use.
But it was great, we sit in the same dressing room where, like, Johnny Cash sat and Willie Nelson and all those guys. That was in itself something amazing - I was on the same space these guys stood on, ya know?
Manners aim to facilitate life, to get rid of impediments, and bring the man pure to energize. They aid our dealing and conversation, as a railway aids travelling, by getting rid of all avoidable obstructions of the road, and leaving nothing to be conquered but pure space.
And when great souls die, after a period peace blooms, slowly and always irregularly. Spaces fill with a kind of soothing electric vibration. Our senses, restored, never to be the same, whisper to us. They existed. They existed. We can be. Be and be better. For they existed.
Every attempt to solve the laws of causation, time, and space would be futile, because the very attempt would have to be made by taking for granted the existence of these three.
We put thirty spokes to make a wheel: But it is on the hole in the center that the use of the cart hinges. We make a vessel from a lump of clay; But it is the empty space within the vessel that makes it useful. We make doors and windows for a room; But it is the empty spaces that make the room livable. Thus, while existence has advantages, It is the emptiness that makes it useful.
A science of all these possible kinds of space [the higher dimensional ones] would undoubtedly be the highest enterprise which a finite understanding could undertake in the field of geometry... If it is possible that there could be regions with other dimensions, it is very likely that God has somewhere brought them into being.
