Anchor one mouth in the present -- say, Nov. 21, 2010. Drag the other mouth through space at nearly the speed of light, until Nov. 21, 2011. Moving objects age more slowly than stationary ones, according to relativity. If you hop inside the wormhole, therefore, you could travel to any point in time in-between, back to 2010.

What would prevent one from grabbing another from the "future", and making a return trip to the "past"?

Here's something to think about... If you could spin a light source, say a lazar light source, at the speed of light, what would happen to the beam of light?

If I knew then what I know now......

So if they create an anchored time/wormhole today, we could at any time in the future return to what we now consider the present. And if we continue making anchored wormholes for future use, say one a week, will they all be nullified if someone returns to the first one and pulls the plug?

Kip Thorne has written a couple of books. A couple of months ago I finished Black Holes and Time Warps. Thorne, like Hawking, does a good job of making the high-level theoretical physics accessible to the layperson.

He also relates some of his personal experiences with the Russian-American physics race a couple of decades ago.

Really fascinating stuff.

I've been on something very close to a time machine... It took me all the way back to a 7th century religious freakdom. You can try out this mode of transport too. Just book here.

That's how the heroes of "Timeline," in theaters next week, travel back to the 14th century (and immediately plunge into nonstop sword-wielding, horse-galloping mayhem).

The energy needed to prop open a wormhole is about what you would get by converting the mass of a large star into energy through E = mc2.

Ok, somebody power up Mr. Fusion and start the Delorean, let's go.

Time travel is a Democrat monopoly.....

[kcordell]

Once you travel to Nov. 21, 2011, could you move the origin of the worm hole from your end and place it in any year in the past? Or can you only manuver a worm hole from it's origin?

[Aquinasfan]

I don't know about travel into the future, but travel into the past must be logically impossible. The effect would precede the cause.

I'm My Own Grandpa...

Many many years ago when I was twenty-three, I got married to a widow who was pretty as could be.

This widow had a grown-up daughter Who had hair of red, My father fell in love with her, And soon the two were wed.

This made my dad my son-in-law And changed my very life, My daughter was my mother, For she was my father's wife.

To complicate the matters worse, Although it brought me joy, I soon became the father Of a bouncing baby boy.

My little baby then became A brother-in-law to dad, And so became my uncle, Though it made me very sad.

For if he was my uncle, Then that also made him brother To the widow's grown-up daughter Who, of course, was my step-mother.

Father's wife then had a son, Who kept them on the run, And he became my grandson, For he was my daughter's son.

My wife is now my mother's mother And it makes me blue, Because, although she is my wife, She's my grandmother, too.

If my wife is my grandmother, Then I am her grandchild, And every time I think of it, It simply drives me wild.

For now I have become The strangest case you ever saw, As the husband of my grandmother, I am my own grandpa!

"Chorus" I'm my own grandpa, I'm my own grandpa It sounds funny I know, but it really is so, I'm my own grandpa!

And there's the rub. Time travelers could never reach a time earlier than when a wormhole was engineered

Damn! I was hoping to pop back 35 years to my highschool girl's locker room for a quick peek. My 35 year reunion was not a pleasant sight........ :)
