Check this one out, Very funny, but kind of wierd too since there is no record of this guy before Dec 2002.

People these days

Welcome to the Twilight Zone. Still, who among us has not wanted to go back (or forward) in time. Now, be honest......... I thought so. I rest my case.

For the record, I have travelled here from a time long ago and from a place far away. I don't deny this fact, nor have I tried to hide my identity. There, I have cleared my conscience for the second time in my life.

loL good answer Dr. G
I too have wanted to time travel.
But I would travel to the past, not the future.
Somewhere in the 1950's mabey early 60's

Mebbe I could could go back and hook up with Jobs and Woz!

MacDaddy, having been born in 1948, if I went back to the 50's, I wonder if I would have the opportunity to meet myself as a child.

Time travel has always been a wonderment to me, and I never fail to discuss this possibility among intelligent people. Of course, I had this discussion about two months ago with a physics prof here at MUN who discussed the theory from a quantum level and lost me after about ten minutes.

There has been discussion of time travel and how it may mesh with the theory of multiple universes.

The theory being; when a time traveler moves to a different time, a new universe is created along that new timeline. (Look at a window that is become frosted and see the intricate lattice work that is created by this wonder of nature. It will give you a physical interpretation of such theory.) This keeps our current timeline from suffering some sort of "temporal tsunami." Reality (or perception) are kept safe.

For a "time machine" that exists today, just look at the night sky. The light from the stars is from the past. You are seeing the sky as it was. Not as it is. Errr. Well, you get the idea. Don't ya just love temporal mechanics? :D

Discussions have already begun on the creation of a "wormhole." (note - generic use of wormhole as a euphamism for many theoretical phenomenon) You get 2 giant steel plates, oh the size of the earth. The energy of an exploding sun and then pull the two plates apart, staying with one of the plates, creating a wormhole. This would allow the traveler to "instantaneously" travel back to the other side. Since time and space are very much related, the type of travel would avoid the regular time dilation problems and would also be another form of time machine.

Another one of nature's examples is the now infamous, black hole. A total breakdown of the space-time conitinuum such that space itself is "folded" in on itself. (sort of like a crushed soda can) Falling into a black hole, the traveller would approach light speeds and time dilation (slowing down of time) would take place for the traveler. (note - of course one would have to survive the incredible stresses and energies, but we will leave that for now. let's just have some fun) The traveller's time would slow down and in effect time would very slowly creep along as he heads towards his ultimate reward - oblivion. An observer would see the traveller spiral into the black hold and then "wink out of existence" as the traveller crossed the event horizon (like the edge of a hole in the ground), never to be seen again.

One last thing before I go; examining Einstein's equations and time dilation equations http://www.macspectrum.com/pic/time_dilation.gif

we see that the equations break down at v=c and v > c, i.e. when velocity is equal to or greather than the speed of light. When v=c, we get something divided by zero. A real no, no. Poof the equation blows up real good. When v>c, we get the square root of a negative number. Ignoring the physics for a moment and just focusing on the math, we know that there are a set of numbers called Imaginary, where the square root of -1 exists as a number denoted by "i". So if we change the domain of the time dilation equation to include imaginary numbers, the equation stands up again.

Possibly this shows that one cannot travel AT the speed of light, but one can travel FASTER than the speed of light.

I know, I know. You're saying, you can't get there from here. How do you travel faster than light WITHOUT travelling AT the speed of light at one point or another? That is left to the professionals.

yUUp, All this stuff can get very confusing.
Like, today is tommorow, yesterday.

Well if gordguide is also from the future, then it would explain his vast knowledge of so many subjects as demonstrated here on ehMac. tongue.gif

Gord, when will the 17" PB's arrive?
And is Apple going to release a tablet mac? :D

macspectrum, what of the "Mobius strip" conception of time?

Dr. G.,
re: Mobius time - simply put http://www.cix.co.uk/~antcom/mtl.html
It is interesting to note that the times at any one place on the loop are the same on both “sides” or “times” and that the arrow of time shown in the centre is always pointing in the same direction. Perhaps this is one way of showing how Time itself could be “twisted” in a higher dimension when it comes to time travelling and is able to cope with any so-called paradox. Thenwhether this Mobius Time Loop is in fact a single universe or that each “side” is a parallel universe splitting at the time travel trip is perhaps something to discuss later.

I prefer the parallel universe(s) theory (aka "lattice work of frost") with each new timeline creating a new universe.

macspectrum, thank you "muy mucho" for the Mobius URL. It explains this concept in a manner which I am able to understand (somewhat).

Dr. G.,
Conduct the little experiment as suggested at the site. When you can actually see and touch the mobius strip, you may garner more insight.
Make it a "father and son" project.

"If I could time in a mobius strip...."
- with apologies to Jim Croce

Now if was dated Apr 1st I might have bit but Mar 19th - I have a hard time even believing with insider info he could do that in 2 weeks??? :eek: :eek: :eek:
Check his DNA that should tell the tale. tongue.gif

One would think that DNA resequencing would be child's play compared with time travel.

Sort of like getting your shots before you leave on a vacation in a far away land. :D

macspectrum, I utilized Jim Croce's "Time in a Bottle" song with my students to have them learn to interpret poetry and then try to teach students the process. Great singer/songwriter.......tragic death.

Dr. G.,
Mathematics, and its younger brother physics, are nature's poetry. At least for me. Yeah, I know. I gotta get out more.

Hence the little homage to Croce.

macspectrum, your comment that "Mathematics, and its younger brother physics, are nature's poetry", is poetically profound.

This has got to be true -- the Weekly World News is always a reliable source. :D I wonder if this man is going to hire Bat Boy as his lawyer? ^^

I wonder how many people are going to claim to be from the future now? *reads through thread* ...hrm.... :D

Never considered imaginary numbers and Einstein...heh, why not? I wonder what engineering with the use of applied imaginary numbers would produce, in a physical sense. O_o;
(Probably something easier to understand than that wordy sentence!)

*scuttles off to bed*

You don't spit into the wind....#

Aw, shucks Dr. G., redface.gif
(commences with "big toe in sand" routine)

macspectrum, I give credit when/where credit is due. Actually, cognitively speaking, there is a connection between math and art/music, where the learning of one helps with the other.

"Goedel Escher and Bach" on your mind perhaps. tongue.gif
I wonder how chaos theory is fitting in with the traditional relationships of harmonics and symmetry. Maybe the slide guitar and the sitar types knew more than we thought :cool:

Dr. G.,
I gots dem left brain blues. :D

Macdoc and macspectrum, check out www.educ.queenssu.ca/~arts (http://www.educ.queenssu.ca/~arts) for some of the latest Canadian studies on this topic.

" ... Gord, when will the 17" PB's arrive?

Ah, yes, you are referring to the PowerBook Riots of 2003. Watch the news, it will be interesting.

And, the tablet has been rumoured to be introduced soon, but of course things are pretty quiet on the runour mills since Apple CEO Reverend Jobs III had the Supreme Court uphold his lower-court decision to send the CEOs of MSNBC to the wormpits of Beetlegeuse for other rumour "hooliganism".

Jobs DID say that this is the YEAR of the laptop, and we still have 9 months left in the year.
