View Full Version : Who is up for some time travel ?

So what's the deal with that? Time travel? I've heard that “Vulcans” prove against it:-)
But still, shrouded by our inability to understand the complexity of the universe, time and everything (A little hitchhiker joke /phpBB/images/smiles/icon_smile.gif ) and our unawareness and misplaced will to kill, the knowledge is beyond us. We've been time traveling in our minds possibly since Adam found Eve in bed with the snake (which may or may not have happened, we’ll never know until we prevail in creating the object in question). I, for one, long to see my younger self (unless Doc. was on to something when he mumbled about the destruction of the time space continuum) sometime in the near future (well past, and for that matter not near - I’m getting older...). What do you think? Does anyone have a scientific insight on the matter?

In theory, according to Hawking and Penrose and Tipler and others, time-space can be distorted under circumstances of extreme gravitational stress, in such a way that space becomes "timelike" and time becomes "spacelike." In theory, then, one can travel backwards in time.

Take note, though, even if time and space were completely flipped...it would take you as much effort to move "one second" as to move "186,000 miles." It would be as hard to go back in time four years as to travel to Alpha Centauri...

So, don't expect to visit Grandfather Adam in time to warn him against tainted vegetable produce...

Weird, a strange person who looks kinda like me only older says he is me and is telling me not to push the "submit" button.

Wouldn't that be cool ? /phpBB/images/smiles/icon_biggrin.gif Oh and I wouldn't worn him, noooo way. As the bible says (not that I’m a scholar...) but he got like knowledge out of that piece of pie, didn't he?

Niven's Law of Time Travel states (and I'm quoting from memory here):
If the universe of discourse allows time travel, and the time traveler can effect changes in the past during such travel, then the simplest single change to the past that would stabilize such a universe is the elimination of the possibility of time travel.

In other words, if time travel did exist, things would just be too weird; and eventually, some time traveler would do something to end the possibility of time travel... and we'd have a universe like ours seems to be.

Many fine SF stories have been written around this concept /phpBB/images/smiles/icon_smile.gif

(Veering back on topic)

Oddly enough, the current issue of Scientific American focuses on time. Some of the articles are online (http://www.sciam.com/) including How to build a time machine (http://www.sciam.com/article.cfm?articleID=0004226A-F77D-1D4A-90FB809EC5880000&catID=2) by Paul "c ain't a constant" Davies.

While it may not be feasible to "travel" into the past buggering up cause and effect, etc. it is certainly possible to see into the past. We do this every day when we observe distant objects. We see the sun as it was eight minutes ago. When we receive a transmission from Voyager (allowing for signal time) we see the solar system as it was 22 hours ago.

If instantaneous transmission of information is ever made possible then a very, very, very powerful telescope could be positioned one light-year away and aimed at the earth. We could instruct it to aim at whatever point on the earth that we wished to observe and see what happened there one year ago. Solve crimes, apportion blame, whatever.

Every event that has ever happened anywhere has an echo radiating through the universe. I think Arthur C. Clarke is working on this idea for a novel at present. He should do it justice. To invent a device that can observe any event at any point in time. Cool.

Well, since we are on the topic of time travel I'll throw this lil'article I found about a "time-traveler". Basically it is about a guy who appeared out of places unknown and then was hit by a taxi. I could sit here and explain the entire article to you but what fun would that be? /phpBB/images/smiles/icon_smile.gif

Clock runs out on long-told story of time traveler (http://www.ohio.com/mld/ohio/news/3846644.htm?template=contentModules/printstory.jsp)


Just had a thought, what if there was a anomaly in space that would reflect light that originated from Earth back to Earth. Could we use it to "see" back in time? And how would that work exactly?

I could see limitations, based on the distance from Earth the anomaly was, of locations on Earth you could see. Of course you wouldn't be able to interact with the past but it would be neat to see nonetheless.


Enjoy

I bring news from the future that the novel will indeed come out (a collaboration of Stephen Baxter and Arthur C. Clarke). I will read it and it will be quite good. It will be called "The Light of Other Days". I recommend that you will read it. Rather, you WILL read it.

No, wait, it's out right now. Sorry.

From a well-known travel guide:



One of the major problems encountered in time travel is not that of accidentally becoming your own father or mother. There is no problem involved in becoming your own father or mother that a broad-minded and well-adjusted family can't cope with. There is no problem about changing the course of history-the course of history does not change because it all fits together like a jigsaw. All the important changes have happened before the things they were supposed to change and it all sorts itself out in the end.

The major problem is quite simply one of grammar, and the main work to consult in this matter is Dr. Dan Streetmentioner's Time Traveler's Handbook of 1001 Tense Formations. It will tell you, for instance, how to describe something that was about to happen to you in the past before you avoided it by time-jumping forward two days in order to avoid it. The event will be described differently according to whether you are talking about it from the standpoint of your own natural time, from a time in the further future, or a time in the further past and is further complicated by the possibility of conducting conversations while you are actually traveling from one time to another with the intention of becoming your own mother or father.

Most readers get as far as the Future Semiconditionally Modified Subinverted Plagal Past Subjunctive Intentional before giving up; and in fact in later editions of the book all the pages beyond this point have been left blank to save on printing costs.

The Hitchhiker's Guide to the Galaxy skips lightly over this tangle of academic abstraction, pausing only to note that the term "Future Perfect" has been abandoned since it was discovered not to be.


For some examples please go here:
http://www.red-shift.net/miliways.htm

Or better yet, consult Douglas Adams' remarkable works directly. /phpBB/images/smiles/icon_biggrin.gif

Just wondering, if you could go back and change your past, would it only be your personal future that changed, or everybodies? Would it be possible to accidentally seal your self in a continual loop from the point you travelled back to up to when you travelled never progressing past the point you travelled back from.Would it be possible to accidentally seal your self in a continual loop from the point you travelled back to up to when you travelled never progressing past the point you travelled back from.Would it be possible to accidentally seal your self in a continual loop from the point you travelled back to up to when you travelled never progressing past the point you travelled back from.Would it be possible to accidentally seal your self in a continual loop from the point you travelled back to up to when you travelled never progressing past the point you travelled back from.Would it be possible to accidentally seal your self in a continual loop from the point you travelled back to up to when you travelled never progressing past the point you travelled back from.

One of the things that gets lost in most discussions about time travel is the "distances" involved. Everyone is familiar with the immense amount of effort that it took to go to the moon, 240,000 miles away--and we haven't been back for a long time.

Whenever we calculate distances in spacetime, we have to use the usual space measurements, but in combination with the time, multiplied by the speed of light. So, in order for us to go back in time one second, we are facing a journey equivalent to 186,000 miles. That's almost to the moon! And of course it would hardly be worth the effort to go back only one second. There might be technological reasons--in computing for instance--to go back a few nanoseconds, which is only a few feet, but it would seem to require too great an effort to send a massive object back much farther.

Pi Man
2002-Nov-21, 08:11 PM
The speed of light simply works as a conversion constant. Just as 12"/1'(12 inches/1 foot) = 1(with no units), 186000 mi/1 sec= 1(with no units)!
