couldn't sleep last night as i was trying to work this out.
What exactly is time in the context of the universe?. I came to the conclusion that time is the rule that governs the universe. Controversialy and not wishing to offend i would go so far as to say that without it there can be no creation or death. Although we know that death is just change when talking about material objects.
Whilst trying to understand i searched for things linked with time and came to the conclusion that matter is linked.
Although time is invisible. It holds no energy or atoms it governs everything in the universe and yet without it the universe would not exist.
I see it now as a sort of self regulator of the universe even though it does not realy exist. Does time exist or is it an illusion?
Anyway, this maybe a bit too heavy to get your thoughts at the moment. Maybe tonight if at all

Things get stranger the more you read about this type of thing.

For example, time slows down for a traveller. If you get a return ticket to a distant planet and travel at close to the speed of light then the journey there and back might take you 2 years (ie you've aged 2 years). However over 50 years may have passed on earth during your journey.

Light is actually ageless, because time has slowed down to zero for it.

I reckon you're right. Time does exist, but if you see all of the behaviours exhibited in the universe on a tree, time is at the root.

From time you get gravity, and energy. From gravity you get matter, and from energy you get magnetisim and electrostatic fields.

Edited to add;

Actually thinking about it, time and space must be at the root of the tree. Perhaps it's different from that which I've described, but I think there's something to the general idea.

Time is a natural property of our universe - just like gravity, matter, electromagnetic energy etc. As Newton and later Einstein worked out, there are strong links between all these elements and they inter-react with each other in all sorts of strange ways. Motion, gravity, energy etc all actually affect the way time behaves, often in a seemingly illogical manner. Part of the "problem" of our understanding of "time" is that, as humans we normally experience time as a staightforward progression of experiences - morning, night, days, weeks, months etc. In reality, time is a much more fluid phenomenon which behaves in a much more variable manner when subjected to large amounts of matter, high relativistic speeds or strong gravitational forces.

It's not "time" that's the problem, just our "human" understanding of it.

Sorry - did you say "What is THE time?

At the moment, about 13 minutes to 11.

That was quick

Shady, go and finish your cornflakes then i'll put CBBC on the tv for you

I was looking for an explanation of time on it's own but the more i think about it the more i realise that without matter or energy it is not possible. It is always linked with something which implies it does not exist on it's own.
So is it an unwritten rule?, THE rule that governs the universe?
Is it possible to seperate time and matter?

Interesting.
i'll have to look up Einstein i think.
Thanks Eric

Time for another one of my crap homemade jokes.

T'other day I was very annoyed when a young whipper snapper decided that he was going to use my herb garden as a short cut whilst out on his new bike.

It was a ride on thyme.

Anyone seen me coat?

Yes I think it is. The reason I was going on about that tree idea, is because it is logical to try and separate out the various attributes of the universe. Y'know, the old divide and conquer idea. I suppose if you want to try and work out how all of these properties link with each other, it helps to know what they are, and how connected they all are.

I suppose the only reason that I propose that time (and space) are loosely at the top of the tree is because they have a bigger hand in what's going on.

As an example electromagnetic energy is never observed to be static. It always fluctuates, it's polarisation is constantly changing as a function of time. It doesn't need space to exist, because it affects matter, but it does not have to affect matter. It's only matter that needs to have space.

On the other hand matter doesn't need time. It could exist on it's own, static, in a cold dead environment.

Then you have things like gravity. Gravity affects matter over time, and does work. Perhaps gravity could be seen as "anti energy". If you looked at it that way then gravity and energy would be peers, matter and fields would be subsets of gravity and energy.

Ultimately though. Time and space affect many things, and few things affect time and space. That says to me that time is at the top of the tree.

Trust me, I know someone, who knows a doctor!

Time. Interesting. I am at work today, showroom open 10-4, snow outside, we are on a side road of an industrial estate that is completely shut down for Christmas. My tyre treads are the only ones on the road. The clocks in the showroom are not moving, so I went outside and timed five minutes, then came back inside and only three seconds have passed by the showroom clocks. I wonder how BT manage to get the clock on the phone system syncronised with the showroom clocks yet isolated from real time too?

so why do women spend so much time getting ready?
