angryjonny's theory #2

[angryjonny]

A time machine that cannot teleport is, in practicality, useless.

Here we go.

The earth rotates on its axis. The earth orbits the sun. The sun orbits the centre of the galaxy. The galaxy orbits the particular cluster of galaxies it is in. The whole universe is expanding and all the galaxies and clusters of galaxies are moving around.

So let's say you build a time machine and move someone six months into the future. In six months time they appear at the exact same spot. Sadly, in those six months, by nature of its orbit, the Earth has moved to the other side of the sun. So the place that your time traveller appears in is now just open space, 186 million miles from their house.

In order to successfully move someone through time you have to be able to predict exactly where the spot on planet earth you want them to appear is going to be (or was) at the point in time you're going to move them to, and move them to that physical location as well as through time. You have to do this with absolute pinpoint accuracy because if you're out by even a tiny fraction of one percent you drop them in the Pacific, or deposit them 1000ft in the air or in the centre of the earth straight into molten magma.

Discuss (if you followed any of that).

[Fawbish]

It's hardly difficult to follow.

Pretty useless (nevertheless interesting) discussion - as no one on these boards is capable of the mathematics required for such an equation - and seeing as no one has (publicly) declared it possible, hypothesising on such is pretty useless...as beyond what you have posited, there's fuck all to hypothesise.

I do however like to occasionally contemplate the grandfather paradox. That stuffs pretty cool.

[angryjonny]

Yeah, I'm just trying to poke holes in all the sci-fi fiction out there that considers the grandfather paradox as a matter of course but quite happily depicts a person disappearing from a place in one time and appearing in exactly the same place at another time.

Except Bill & Ted, who also teleported in their phone box. Who would have thought Bill & Ted would be one of the 20th century's more accurate time travel stories.

Worse than that, the solar system is travelling around the centre of the milky way, which is itself travelling through space at 'astronomical' speeds (sorry).

What it does bring up though is the possibility of using time travel for actual travel. ie travel through time in the same spot and eventually something else will come nearby...

Of course time travel is only possible in one direction and we're doing it... Brian Cox's 'Why does E=mc2' is a good read that explains much of this. You can however vary how quickly you ravel in that time direction by moving faster or slower.

Maybe the time travel has some sort of particle-lock which traces back through time. Could also be centred around a gravitation source.

[D O G]

Buit then you'd have to teleport the rocket too!

[G]

And you'd have to have an idea of what 'the centre of space' is.

Oh and some kind of worm home, space distorting etc drive, as with traditional rocket power you'd probably arrive after you left anyway .

Surely the process of teleportation requires the manipulation of spacetime itself, so the location is automatically factored into the calculation that allows the process to occur in the first place, thus nullifying your quandry?

Given that a lot of these science fiction types like to use the quantum entanglement concept as the underpinnings for teleportation, it's a non-issue, as far as I understand it. You've automatically got a temporal and physical lock point, if you're entangled with the destination.

I'm working on a time machine. I will shortly be trying it out. I wonder if it works?
