Time/ Space: from Hawking back to Einstein / Minkowski. ==… a) Stephen Hawking, book: "The theory of everything. Fifth lecture." " . . . . the universe must have a beginning, and that this beginning must be described in terms of quantum theory." "When one goes back to the real time in which we live, however, there will still appear to be singularities. The poor astronaut who falls into a black hole . . . . could live in imaginary time, that he would encounter no singularities." "This might suggest that the so-called imaginary time is really the fundamental time, and that we call real time is something we create just in our minds. In real time, the universe has a beginning and an end at singularities that form a boundary to space-time and at which the laws of science break down. But in imaginary time, there are no singularities or boundaries. So maybe what we call imaginary time is really more basic, and what we call real time is just an idea that we invent to help us describe what we think the universe is like." / page 91/ So. The real time in which we live has singularities. But imaginary time without singularities or boundaries " is really the fundamental time", " is really more basic. " b) Einstein /Minkowski. It was Einstein who first in 1905 introduced imaginary time in SRT. In 1908 Minkowski changed imaginary time into 4D and said: “ Henceforth, space by itself, and time by itself, are doomed to fade away into mere shadows, and only a kind of union of the two will preserve an independent reality.” So. " space by itself, and time by itself" the real space and time in which we live are "shadows" . . . . " and only a kind of union of the two ( on the basis of imaginary time) will preserve an independent reality.” ==.. My solution. An imaginary time means a situation of absence of Time. The situation of absence time means Eternal condition. The Eternal condition belongs to Infinite zero vacuum: T=0K. The black hole is eternal zero vacuum (T=0K) continuum. The 4D is eternal zero vacuum (T=0K) continuum. Space by itself (gravity-space) and Time (gravity-time) by itself are secondary: made out from the eternal zero vacuum (T=0K) through singularity / vacuum fluctuation-transformation. ===… Best wishes.

This imaginary time.... what is it like if we were to live in it? Knowledge of this changes how we act, react, interact how?
A black hole has temperature of only one ten-millionth of a degree above absolute zero. In 1973 the temperature of the cosmic microwave radiation was about 2,7 degrees above T=0K. If the universe is destined to go on expanding forever then the temperature will eventually decrease to less than that of black hole . . . to zero: T=0K. So. There are three basic similarities between black hole and zero vacuum: a) both have imaginary time b) both have the same temperature c) both can emit radiation in the form of "virtual particles" Therefore black hole is zero vacuum. =============..
