h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

Angelof 2nd good point, no time like the present. Have I got time for this?

re: The "twins" paradox, with twin "A" travelling at (say) .95C, and twin "B" stationary,...

After 1 hour, A is one second younger than B (arbitary figures, but right sort of scale...)

After 2 hours, A is 2 seconds younger than B
After 3 hours, A is 3 seconds younger than B
After 4 hours, A is 4 seconds younger than B
After 5 hours... etc.

So, relative to B, A can be said to be travelling backwards in time...

What planet do you come from? Where time does not exist.

Time isn't anything, it's just a result of bizarre human perceptions. "Any people you may happen to meet are merely figments of a derranged imagination " - the Guide. It is easy to place time and space into the same catogery.

Time is the difference between the nut and the tree.

!/Time is before eternity and it is eternity that counts.
I think you have to hold on to your time and carry it with soft hands and in the same time willingly give what you can....
/The 2nd moon has long been in a shadow but now you can see the light of it... and I hope you understad me, although I´m from far out.....Time travelling must be a little like this.. If you sit under a tree and a nut falls...?
/where can I find my moon sign?

Thank you!
What is your opinion,is time -travveling anything for you? Are you a policeman?
What is the greatest on this planet?

I'm not a policeman IRL, just on H2G2...

I think the best thing on at the moment has to be Alyson Hannigan, in her role as "Willow" on BtVS...

For my opinion on aspects of time travel just wander around the site - I'll get around to posting it a week or two ago.

!!! I will look out for it.Will this compendium be heavy?
If time-travveling was/is possible I would wait for you on my moon and give you some ...000000

I believe you could come back to the point that you left and thus carry on your existence. The only "additional" four days would be experienced by you. You could also choose to come back four days after you left in 2002. All that would mean is that you would not experience four days of that calendar year.

4 days to do what ever I want, and nobody would miss me or ask me to do things...sounds tempting...but time- travelling in my mind is combined with scary machinery from old films...

time is ....just now!or was?

No, I am not. time is definately built into the fabric of the universe (or in some theories into the fabric of the multiverse), but it is built into a non-newtonian universe.

Unfortunately, all of our references to time are either referencing the newtonian world view, or more often the aristotelian world view.

There is therefore a significant semantic mismatch between the phenomena we wish to talk about (time) and the language we use to talk about it.

This always leads to misunderstandings.

for example:

"In fact in some sciences (ie general semantics) simultaneity is viewed as illusionary, determined only by the location in space-time of the individual."

Let me get this straight.. what you seem to be saying is that there IS a time and place for everything?

my comment (in it's original context) refers to the lack of aplicability of some of the language used in these conversations to be used in the way people are using it.

your response is definately asking how this comment fits into the newtonion vision of the universe, with it's idea of being able to construct a chronometer of absolute time. Einstein proved that the construction of such a device was impossible.

It also is asking if I am saying that pre-destination exists. (for clarity, I am not).

What Is Time?

If we look at this question closely we can see that it is really rather simple... how do we know time? First by the changing days and seasons, by the movement of the sun and moon, and then by the swinging pendulum and the quartz controlled digital clock... and so what is at the heart of all this measurement? Change. Time is Change. When we think of time stopping what do we imagine? Nothing changing. And when we want to go backwards in time, we want to change things back to a certain way that they were in the "past", but the past does not exist. The past is only a certain arangement of the energy patterns of the universe. It is like ashes, and the future is only a shadow. The only thing that exists is this moment, and this moment indeed has no objective reality. It can only be experienced by the perceiver, a totally subjective view. We seem to notice differences in the flow of time and coin phrases like "time flies when you're having fun" and we all know how it drags on when we are bored. This is directly related to the rate of change, when very little is changing time seems to slow down, and when there is much activity and change it speeds up. Time is merely a convenient way of keeping track of change, which is of course, the only constant.

"There is a Time and Place for Everything" is quite literally true. a moment can be described as a coordinate in space/time, so by describing a time and place you define an event.
The concept of taking the physical body through time is an interesting if far-fetched notion, however if one leaves behind western science in favor of oriental mysticism then time travel becomes a rather simple affair.... since this world is not real anyway, and we all are actually spiritual beings with existance beyond these physical bonds, time i sonly an inconvenience to us while here, and our extra-dimensional selves perceive the universe in a totally different way... but that doesn't mean we shouldn't look for ways to have physical time-travel, since it would be so vastly entertaining, just that there is no need to worry too much if we can't

H.A.

Hiram Abif! 1)I agree with you in most of what you are saying,especially the second part!!! that´s what I have been trying to say in this conversation.
2)If your body is not ONLY your brain...but a wind of eternity , a mind without time bonds...
3)Time travelling-- just to arrive to a special moment or so,is fun to think about!
And There´s a time for every purpose under heaven....A time to love, a time to hate, a time to get, a time to give, a time to stay,
a time to go..
If you put me in a refrigerator and put time around me and throw me out from a spaceship --then what?????8-0..

I definately agree that we measure time as a change. But I think it's good to remember that that measurement of change is based on individual perspective. Someone close to an even would see that change in time sooner than I would, they would say it happened about one second earlier, depending on what the distance between me and them is. (because of the fact that light has a finite velocity) So looking at it this way would put them in the past, relative to me. That's what relativity is all about, time is not a constant, it's relative to the observer.

I see a lot of talk about people traveling into the past, and I'm not going to say that it can't be done. But maybe this will help. Try to remember that we perveive /everything/ in the past. Even from the closest object that you can hold up to your eye, they light took a change in time to reach you, so you are really observing what the object looked like that long ago. Even though a time difference of .0000000000000001 nano-seconds isn't really that signifigant, it's definately there.

Yes, I agree,but you have to enjoy yourself too....and time is holding it´s grip over . Nobody has time enough, and now I just ran out of it...

Yes, I agree that we should have fun while were here, and that time has a grip over us. The only reason that time does have a grip over is because we as humans observe and measure it, and run our daily lives on it.

Without this human *desire* (not for me, my computer clock isn't right, and I don't wear a watch) time would still exist. We just wouldn't care.

What about me in that refrigerator in space???? Answer me anyone!
I care, but I don´t wear a watch eather...I put my hands too much in water,...-when I´m not lost in space inside a refrigerator....help me someone! of 2nd
