@ Space and Time

I would like to have a few talks about space and time, which are one of the most universal concepts and the root of our sense and perception, from a view point that I have been feeling or thinking for a long time.

Space and time are usually perceived or talked as a couple of concepts; while, in physics or cosmology represented by the Einstein's theory of relativity, they are used as a unified concept of space-time.

There are a lot of amateur cameramen who take a very fine photo; however, a prominent professional cameraman shows us a photo which catches something decisively different from one of an excellent amateur cameraman, something powerful or sharp.



Amateur cameramen take a photo by instantaneously cutting off space, while professional cameramen take a photo by cutting off time folded in space, don't they?
Traces of time folded in photos of professional cameramen may be something decisively different, mayn't it be?

It is said that people living in small islands in the vast Pacific Ocean, such as Polynesia, Micronesia and Melanesia, emigrated from South East Asia, such as the Philippines and Indonesia, throughout the ages. It is believed to be an important ground of the above story that the language of native Hawaiians has a lot of similar points to Indonesian language and others in South East Asia.

Boarding a canoe without an engine or screw, having no compass, how did they sail from Indonesia to Hawaii sailing across raging waves of the Pacific Ocean? Of course they didn't directly sail from Indonesia to Hawaii, but proceeded from island to island taking a long time, probably.

Such rigging as a ship or a compass is very important; however, it is a further bigger enigma how they could be sure that they would be able to reach an island beyond the horizon in the period when there was neither a reliable map nor an artificial satellite photo. As they were well versed in catching a fish, they could probably get a fresh supply of animal protein during their considerably long sailing period; however, if they could not reach any island during the sailing, fresh water and vegetables, indispensable for human's survival, would run out and all of them would die. How could they overcome such terror?
People who sailed toward unseen islands beyond the horizon might have travelled not in space but in time, that is my hypothesis. Something like confidence that they would surely reach somewhere after several days, weeks or months inspired them who boldly pulled out to sea toward the horizon on which nothing could be seen, didn't it?

A long time ago when I worked for beatifying the whole Baghdad, I went out to every place in the city of Baghdad every morning. I often saw an old person who stood at the entrance of a house beside my office from the morning and still did so in the evening when I came back to my office.
As it was so often that I could become unbearable and, one day, asked my Iraqi colleague "What is looking at?" The Iraqi colleague calmly replied "nothing in particular" only, even he showed a dubious look like "What is he asking?"

In a flash I intuitionally realised "Ah, this person has been looking at not space but time, so he has never got tired for hours", I'm not sure if it was correct or not.

The attached photo is the Polynesian nautical chart which is said to be one of the treasures of the National Ethnological Museum. The museum's explanation tells "It is made with leafstalks of a coco and shells. The shells show the location relations of islands, and the leafstalks of a coco show the directions of heaving sea. This nautical chart was made for education. It was not brought in actual sailing.
