How do we explain computation or communication without time? Why do digital computers have a clock, or why does communication involve synchronisation?
Its about order , or better coordination , and why time zones were created in the first place , by Sanford Fleming
Without time zones , way back when , every town was its own time , hence chaos , when does the train come in ...
Why can't we think about communication without time? If by communication, you mean signals from place to another, involves change, nothing more.
No, there is one basic scientific method, that acts as a foundation.
Most of us learn from others in many respects...standing on the shoulders of giants and all that.....You need to get out from under that rock.
Oh but he did align himself with mainstream science...Maxwell, Lorentz, and others, than followed the scientific methodology, including Imagination, Innovation, and observation.
Time exists of that we can be sure. Like matter, it evolved along with space from the BB, and each is as real as the other.
The rest is mere details.
You keep making this statement and I keep replying to it and you keep ignoring it. As I have asked you before, if that is so, you better have a solution to how you deal with time at the BB since there is no metric at the beginning, you start off with a point with no spacetime present. So tell me, how it evolved along with space from the BB?
So no, time doesn't evolve from space from the BB. Neither space or time existed at the BB. Space and time are emergent properties. So if you can stop dodging this question, it would be good.

On what basis is time " real " as compared to matter ?
Oh and another one, Paddo, how do you define time at the big bang when there was no matter around? All that existed was radiation fields and no time passes for these in relativity. So without any clocks in your universe, how can you define time?
That's another one for you to answer for us.
That's another one for you to answer for us.
The laws of physics as we know them didn't apply until $$10^{-43}$$ seconds after the big bang.
That's why space and time break down as fundamental properties of the universe. Remember, BB hasn't ended, BB is still happening. But space and time was not a fundamental part of it, in fact the universe has to cool down first to allow a notion of dimensions and symmetry breaking to allow moving clocks so we can even define time.
Just because we weren't there to measure it, doesn't mean it didn't exist.
And again, I did not define time at the BB, nor anything else.....I defined time as that which evolved along with space, gravity, matter, and energy from the BB, and which we can only really know about from 10-43 seconds after the Initial event.
Now how many times do I have to repeat that.

Experiments continue to show that there is no 'space' that stands apart from space-time itself...no arena in which matter, energy and gravity operate which is not affected by matter, energy and gravity. General relativity tells us that what we call space is just another feature of the gravitational field of the universe, so space and space-time can and do not exist apart from the matter and energy that creates the gravitational field. This is not speculation, but sound observation."

we/scientists/cosmologists do not know...We need a QGT to describe anything prior the BB and 10-43 seconds after that event.
I'm dodging nothing. Your question has been answered many times.....The problem appears to be that your blinkered view will not accept that.
That's your problem.
Space, time, space/time, gravity, matter, energy all evolved from the BB.....
Hope I was of assistance this time round.
Not true. Time couldn't have appeared because of the laws of physics. Relativity states clearly that time is only experienced by moving clocks. And another thing, the whole 10^-43 second thing is called the Planck Epoch, and no, the laws don't apply after this initial event either.
There is something called the Grand unification epoch which followed the Planck epoch and at this stage, the universe had an electronuclear force present, there was no notion of mass, in fact, as wiki explains below, the notion of matter and even charge itself is redundant
http://en.wikipedia.org/wiki/Grand_unification_epoch
Now I am sorry to disappoint you, but you can't say, ''just because there are no clocks, doesn't mean it isn't there,'' quite the contrary, it must mean that time isn't there since this is how time enters physics, through principles of relativity. Also that isn't how we do physics, you can make the same argument for God if you where religious... just because we can't see him, doesn't mean he isn't there! lol
everything evolved from the big bang but you don't seem to understand the importance of a chronological set of events. Matter did not appear at the BB nor was there any space or time, nor did any matter appear until symmetry breaking occurred, see my post above, this means you can't have your way on this matter. Time is defined by moving clocks, there where no clocks for a while until the universe grew relatively old and large and sufficiently cooled down. This is when you can begin to measure change and start calling it time.
Yes they were. The BB was in fact a creation/evolution of space and time [as we know them] in the first instant.
Matter came later.
The expansion we observe is a result of the BB and whatever impetus there was behind it.
It's in actual fact an expansion of the Universe/space/time.
That would be exactly right!
Paddo, I have just written two posts above explaining why you are wrong. If you can't still see why, then just stop talking to me because we won't get anywhere.
Yes, but doesn't change what I have been saying. You still don't have any matter present even after this Planck Epoch. Also, there is no notion of space or time at this initial stage, indicating it is an emergent phenomenon.
