An Essay on Fundamental Philosophy
Warm-Up Savants generally consider the age of the universe to be in the range of fourteen to twenty billion years, a finite number. If the velocity of light is finite and constant, as the savants believe, then by the laws of transfinite arithmetic a light signal run backwards would arrive at the beginning of the universe in a finite time. There it would have to halt, since no space-time can exist beyond the beginning of the universe. Consequently no science, nor thinking of any known kind including the artificial intelligence type, can be possible beyond the beginning of space-time. Some have claimed, however, that there is an Ultimate Source of All Existence beyond the beginning of the universe with its space-time. A light signal departing the earth can be vectored in any one of 64,800 directions, If only intersections in whole degrees of latitude and longitude serve as launching points. Over long distances, the light signal is expected to encounter on average the same distribution and density of matter, regardless of the direction to which the light signal is vectored. The former property of the universe is called isotropy, the latter homogeneity. These properties, however, are only abstractions that cannot be corroborated beyond a doubt, needed though they are for generalizations about the universe. If the beginning of the universe is unreachable in a finite space- time, implying that the space-time is infinite in the direction of the past, there still would have to be an Ultimate Source of...
