Blaine Barkey asked the Naked Scientists:
Hi Chris,
Love the shows - please keep up the great work (http://www.thenakedscientists.com/HTML/podcasts/)!
I was wondering what would happen if you could actually stop time? Would you be able to actually see anything? In other words, if our ability to see things relies on light waves bouncing off of objects, and the light waves stop when time stops, would you still be able to see everything around you?
Curiously yours,

What do you think?
-
Nothing would happen - literally. Everything would be frozen and nothing would be functioning. Having said that, many (or maybe even most) physicists appear to believe that time doesn't flow and therefore cannot be stopped in any meaningful way, but I'll leave it to one of them to try to explain that.
-
'Time' is an integral part of the fabric of the universe. Therefore the concept of stopping time becomes meaningless within the constraints of the universe. As a mind exercise it is possible, as David points out "nothing would happen". Nothing happening includes your thought process so you would not even be aware of it and a clock could not register or record it. Your thought processes being frozen in time would not be accessible (non-awareness), everything would be a timeless blank.
-
It depends on what you think the 'arrow of time' consists of? Is it local 'changes' or is there a 'ocean of time' with 'local stream(s)' becoming the arrow we see?
It may 'stop' and 'start' the whole 'time' for all we know :)
We would never notice that.
-
While I'm sure the above posters are correct, I think, if I understand you correctly, if time were to stand still but you retain your consciousness, then the answer would be no, you would still not be able to perceive anything. In such a hypothetical situation, as you rightly surmise, light would stand still, so it would not enter your eye, thus you could not see.
However, you would be able to catch that train you are late for, if you could only see it.
-
you also wouldnt be able to breathe or hear and it is possible that because atoms have stopped moving you might shift through solid matter. good news you cant be burned :)
-
If you stopped time the pink unicorns would come and take you away.
-
If time stopped, you would not know. How would you be able to tell that it had?
I have it from a very good authority that time actually does stop every other Tuesday in months with an R in them.

I knew something was going on (or not, as the case may be). Only last Tuesday, when 'er indoors left orders for me to clean the oven (a task I find particularly irksome), I did not do it. It can only be because time stood still just when I was going to carry out this most hideous of tasks. I'm sure she will understand when I explain this phenomenonmenonmenonmenon* to her.
*I always have trouble knowing when to stop with that word, it was always the same with that fine English actor, Edward Woodwardwoodwardwoodward. See what I mean!

And the fact that you broadcast our regular time stops is why you never made it to the inner circle - call yourself an illuminatus and you cannot even keep a secret! Brother Biggles bring me the tome of transgression....
A local stoppage of time, or a local bubble which avoids an otherwise universal stoppage of time would be interesting - but almost certainly impossible in so many ways. The boundary/horizon between normal and stopped time would be an interesting and I think fairly hot and horrible place.

So our oven has got something to do with it!

Uh, that sounds like the EH of a black hole. Horrible yes! Hot, thats debatable, if feeding yes, if not then no.

You might want to read up on possible outcomes of lowering a thermometer from a safe orbit towards an Event Horizon. It's Hot. It's also very complicated and possibly contradictory - but it is hot without matter falling in from outside.
-
yeah but the inside might be impossibly cold if it can get matter to stop moving inside it

Can you give any references please?
The way I understand it is
" If one only considers black holes classically, then they have zero temperature and, by the no hair theorem, zero entropy,"

Hang on !...I get deliveries on a Tuesday !

This is very much a non-classical treatment - we have already through work of hawking and bekenstein discovered that blackholes have a temperature etc. so a classical constraint is a little too much. the qm behaviour of "empty space" at any horizon is very odd.

Are they late every other week? If so, I think Geezer must be on to something.

how did they discover black holes have temp? ???

Then radiated photons destroy all,because they will have gammashift.

Punctuation may not have been a strong point either.

Thank you, I'll work on that. Great, topic.

"Time all time is centered around matter and all moments of time are in the present since the future and past perceptions of time are a human traits outside the realm of reality."
No, probability builds on the concept of a past, without a past to look at probability wouldn't be computable as there would be no data. And as it works very well, the past must be inside the realm of 'reality'. Any book you read is written in the 'past' defining the future on good and bad.
-
I’m not at all sure that I understand artpiecemalpasso. Apart from that, though, I’m OK with the general ideas. However, it does seem that what we are talking about is change, rather than time.
Change requires activity. Activity brings about change. If all activity stopped, there would be no change, and nothing for time to measure, so time would have no meaning.
It would not be meaningful to talk of time having stopped, any more than it is really meaningful to talk of time as moving under normal conditions.

Art,
Try the "three sentence rule". Basically, it says that if a paragraph has more that three sentences, the audience is likely to depart.

lol, I appreciate your criticism, but it is a learning disability, I have been dealing with it my whole life, and Im not real sure about your intent to keep bringing it up, it might be an area that never improves but does it take away from my soul in my mind, no, The mind is a limited, limitless, possiblity of imagination and bueaty, sometimes things go wrong like the car wreck I was in as a child, I apologize for not being able to spell great or punctuate properly, I might never be able to, Good day.

We have time to not study time.I don't know what is time.I can not understand time without experiment with synchronization of clocks on a satellite.

Very helps to be confused.I will make law of time in New Theories.

Add math to this.

Im asking for help from any one who is able to help me post my findings in a journal, I would greatly appreciate any help in this matter, I do have internet publication I have Intellectual rights over my theory since my Blog publication dates, but I would really be interested in working with a professor, to get to the bottom of its truth, and then a possible journal. Please if anyone could help me with this matter. Im tired of defending my Ideas with banter. I would love to get serious about the theory with whom ever would like to help me with this. My theory is base on the absence of the past and future time realms. We can exchange emails if anyone is interested, I dont care if I post my email, Its my business email. Im not sure if we can send personal messages, if so thats a good way of do this. I also have other theories but I dont want to even attempt to go any further with out getting a consensus on this first thank you agian. Artpiecemalpasso
-
Did you add the math to my theory????
-
Im not sure if simplified work out a formula for my Theory but it looks like a law of time, do you know him????? Is this pertaining to my theory a little confused.
-
Do you know simplified, it looks like he worked out a law of time, does that pertain to my theory???, Im not sure... Maybe he did this before my first post??? Anyways just need your advice on that. thanks. Artpiecemalpasso
-
Did you add the math to my theory????
Maybe.

Time is energy and energy is time. Particles are always moving like atoms and if you stop time you would have to stop movement or any other kind of energy in the entire universe. The whole universe would have to transform to nothing. Almost like reverse Big Bang. But thats just my theory.
