What is Time?
However, in the pragmatic sense, that is also a level of Truth — though a lesser Truth.. Barin

Earlier, I referred to Stephen Hawking [in an error in typing, the name was printed as Hawkins, for which I am sorry]. Hawking is the newest scientist-thinker who does not believe in the concept of 'singularity' of the classical Big Bang theory. And in his concept, the extension of universe is beyond time and space, that is, eternal. He has said that there are and will be several universe. There will be no end. No end of Matter. No end of universes. No end of Time and Space. There is no limit, no boundary. His thought is very close to Indian Philosophy. “In collaboration with Jim Hartle, Hawking developed a model in which the Universe had no boundary in space-time, replacing the initial singularity of the classical Big Bang models with a region akin to the North pole; while one cannot travel North of the North pole, there is no boundary there. While originally the no-boundary proposal predicted a closed Universe, discussions with Neil Turok led to the realization that the no-boundary proposal is consistent with a Universe which is not closed also.” {Wikipaedia] |

Several questions related to time are reproduced below.—what time actually is; whether time exists; what kinds of time travel are possible; why the time dimension has an arrow but a space dimension does not; whether the future and past are real; how to analyze the metaphor of time's flow; whether the future will be infinite; whether there was time before the Big Bang; whether tensed or tenseless concepts are semantically basic; what is the proper formalism or logic that captures the special role that time plays in reasoning; and what are the neural mechanisms that account for our experience of time. Some of these issues will be resolved by scientific advances alone, but others require philosophical analysis. |
