Time Travel Project...

[kindergoth441]

Well our teacher wants us to build a model expressing time travel...we have like a month to complete it. it has to demonstrate time travel or a form of how time travel could work and it has to be...well nice. So...any ideas? I was thinking of making a model of a worm hole or something but I am lost. Any suggestions?

[Tormod]

Well, we'll probably never hear form Mr kindergoth441 again. But I wonder...what would a model of a worm hole look like?

And how do you demonstrate time travel? Seriously - could it be done? Not actually travelling in time, but to create a model which describes the concept? What would it look like? Could be a fun project for my real life job at the space centre.

I can't think of a small scale model, but it sounds like a great ride for a theme park. Put people into a capsule, send them at high speed with a bunch of bizarre lighting effects to a predetermined point in history or the imagined future. You could have all sorts of interesting time periods and places-past and future. The Renaissance, inquisition, early Rome and Greece, Mars colony, WW II reenactments......Just how BIG is your BUDGET? Think how much money you could make sending Christians to Jerusalem ca. 1 BC to 40 AD... Then have technical problems with the time machine and just leave them there...HaHa ! I may be on to something big here??

Actually, we would WANT them to come back. So they could tell all their Christian buddies that it IS a joke! That it never really happened.

But then we would be accused of having brainwashed them or exchanged their bodies like some kinda pod people.

OK, while the ribs are on the grill being smoked in Mesquite.

When the discussion is "what would a worm hole look like?"

One has to ask, would it be a VISIBLE phenomenon?

What does a blackhole look like?

We have some concept of what the event horizon looks like, but the hole itself? What would make it a VISIBLE phenomenon?

The question would be, not what does it "look" like, but:

"How do we 'REPRESENT' a worm hole?"

Seems like, rather than representing it as a tunnel or such, asi ti usually is, the trick would be to 'REPRESENT' what it does.

Perhaps have some flat surface with a star field on one side of a box and the same on the other, but a different star field. Each represents different spacial locations. or different times at the same spacial location.

Then have some object that you shove into a hidden hole on the one side and have a perfect copy of it coming out the other in sync.

I've always had trouble with the "dimensional stretch" CGI so common in effects. What you are doing is connecting to different time/space locations with a common juncture. A Boolean operation. a common plane between two 3 dimensional objects. I used to sell high end 3D software and saw how it would work graphically. The common surface would be a 2d plane at a given juncture or a 3D area of commonality.

Hmmm

One of the infationary universe theories I have heard of involves universes expanding at the speed of light towards each other. Where they meet, one destroys the other. The other just stops existing at any intersecing/ common space.

What if that common space is NOT destructive, not subtractive, but either additive or in some form averaged/ common? Then the entrance to a worm hole would not be some funnel, but a 3D area of commonality. You would enter this 3 dimensional common space and exit some other point.

Hm. these are good suggestions. I will try to discuss this with one of the folks who creates things for us (ie, a magician, some call them designers) and see if he can't come up with something intelligent!

The simplest model that explains time travel would be a light clock.

Don't need of building anything.

Just presenting yourself to the judges and in front of everybody close firmly your eyes, make an expression like if you were making a great effort of concentration and say that you have disappeared from the room and that you are somewhere in the past or the future.

Your prize will be a T-shirt with the picture of that lunatic of Einstein and a free ride to the closest mental institution.

Good luck.

[Tormod]

Well, at least if I claim to be in the future I have a fair chance of being correct.
