Time

Following up Cameron's fascinating discussion yesterday of time travel...


"People like us, who believe in physics, know that the distinction between past, present and future is only a stubbornly persistent illusion." Albert Einstein
[Why time is relative-video]

Time didn’t exist before the Big Bang, so there is no time for God to make the universe in. It’s like asking for directions to the edge of the Earth. The Earth is a sphere. It does not have an edge, so looking for it is a futile exercise.” Stephen W. Hawking

“Time is but the stream I go a-fishing in. I drink at it; but while I drink I see the sandy bottom and detect how shallow it is. Its thin current slides away, but eternity remains.” Henry David Thoreau, Walden... And, “As if you could kill time without injuring eternity.”

The Vulcan Science Directorate studied the question of time travel in great detail. By the mid-22nd century, they found no evidence that it existed or that it could exist, ultimately believing that its concept was "illogical". However, the Directorate had no trouble accepting the existence of micro-singularities or the notion that regions of space in the Delphic Expanse failed to conform to the laws of physics. (ENT: "Cold Front", "Shockwave, Part II", "Future Tense", "Shuttlepod One", "The Expanse")...

"Suppose that time is not a quantity but a quality, like the luminescence of the night above the trees just when a rising moon has touched the treeline. Time exists, but it cannot be measured..." Alan Lightman, Einstein's Dreams
