The discussion centers on the concept of "dark time," a theoretical idea suggesting a region of space where time may not function as it does elsewhere. Participants debate the validity of this concept, with references to established terms like "dark matter," "dark energy," and "cosmic dark ages." The conversation highlights the importance of precise terminology in physics, noting that "dark time" is already used in cosmology to describe a specific period in the universe's history. Ultimately, the notion of dark time remains speculative, lacking empirical evidence or a clear theoretical framework.
PREREQUISITESPhysicists, cosmologists, and anyone interested in theoretical physics and the exploration of time-related phenomena.
geelsu said:I really don't know what I mean. I haven't even formulated a descent hypothesis. I don't think I would call it anti-time or time flowing in reverse. I'm just chewing on the concept a bit and trying to decide if there is even a possibility for it. If all the dark matter is there, unseen, and dark energy models continue to refine, then what perhaps a dark time might also be "out there."
Pengwuino said:no one would have thought there's a relationship between the two (which there is not)
phinds said:You should be careful with your terminology. There IS a "dark time" in the history of the universe (after the surface of last scattering and before the creation of stars) so that term is already taken in cosmology. You'd have to call what you're talking about "strange time" or something.
Chronos said:I believe the period just after recombination is referred to as the cosmic dark ages.
CosmicEye said:I think its an interesting question, but time is not a physical object that we can see
Oldfart said:All of which makes me wonder about dark space, and dark spacetime. Where dark spacetime curves away from massive bodies unless they are made of dark matter. Makes my head hurt...
MrGodParticle said:im pretty sure that if there is time in space at all, then it would be dark spacetime because space is all dark and it is made up to dark fluid and dark matter but I am an amateur so I am not exactly sure
phinds said:I do not wish to be rude, but you seem to be tossing out words in ways that have no relevance to actual physics, just because the word "dark" has other connotations in the English language and makes them seem similar if you have no idea what they mean in physics.
I see you are new here, so probably you have misunderstood the purpose of this forum. Folks here are very friendly and get quite lighthearted sometimes, but basically this is a serious physics forum and just tossing out poorly formed statements is not really a good idea.
MrGodParticle said:Actually, not to be rude but i got the "dark fluid" portion of my response from this forum. So go burn the individual that provided that information. Also i did not misunderstand the purpose of this forum, but thank you for your concern.
shifty88 said:i think op means night time.
phinds said:Well, you might want to think some more. In the context of this thread, it's pretty clear he's not talking about night.
shifty88 said:I must point out that i was making a joke, he obviously doesn't mean night time... what's wrong with you.
I have no idea what 'dark time' could be or why physics would require the concept of dark time to begin with.
Even the Op doesn't know what he's on about.

shifty88 said:As far as I am aware Dark matter was thought up after the discovery that there isn't enough mass in galaxies to hold them together.
Dark energy was used to explain the acceleration of the expansion of space.
What odd unexplainable observations are their that would need a theory like dark time.
None that I know of, which doesn't rule out the possibility, it doesn't seem like science to me
salvestrom said:Your statement about dark matter is absolutely correct, of course, but the point is that until 1970's they didn't even know there was something odd about the rotational speed of galaxies. Who knows what odd things are as yet unobserved. I agree, though, that there are no known unknowns that might be explained by some new, odd behaviour of time.
Oldfart said:What? By any reasonable measure, cosmology's greatest all-time unknown involves T=0, at the start of the universe. If dark time (or whatever you want to call it) theory could explain how the universe came to exist without having a beginning, it would surely represent mankind's crowning scientific achievement. Loop quantum time, anyone?
