It would be pretty cool if we can extend it to all body parts and achieve the eventual goal of immortality. But it is probably going to take millions of years for that to happen.

I would say that space travel will be the next big thing. I would be surprised if a base is not on Mars by 2070.

Or lose the race to rats
Get caught in ticking traps
And start to dream of somewhere
To relax their restless flight
Somewhere out of a memory of lighted streets on quiet nights..."

I think the brain will take the longest, but we already have some organs doable with others like kidneys and hearts quickly coming down the pipe.

Sounds interesting, but I'm not optimistic. Hawking suggests that we'd necessarily be traveling through time if we traveled above c, and time-travel is ripe with paradox. If you took a trip around the solar system at warp, you'd arrive back at Earth before you left. True story.
Beliefs in a nutshell:
- The Ends never justify the Means.
- Objectivity is secondary to subjectivity.
- The War on Drugs is the worst policy in the U.S.
- Most people worship technology as a religion.
- Computers will never become sentient.

There was a young lady of Wight,
Who traveled much faster than light,
She departed one day,
In a relative way,
And arrived on the previous night.

If we were destined to travel above c, then we'd already know about it.

It's really cool, but it also is a sign that the universe probably censors such activity. The only way it would make any sense is if an alternative timeline were created (i.e., where killing yourself in the past wouldn't create a paradox). However even this becomes somewhat hypothetically ridiculous if you play with the idea enough. It seems much more likely to me that we're simply going to find more clever ways of exploring the universe, perhaps with Michio's idea of self-replicating probes. I also like the K-Pax concept of sending your consciousness without a physical body. Once mass is removed from the equation, a lot more liberty is possible across the board. I'm optimistic that we will find SOME way of sating our thirst for knowledge, but I don't think we can understand exactly how at our present technological state, any more than Renaissance thinkers could have predicted the internet. Although I am a huge Star Trek fan, I am also a huge opponent to the idea that virtually anything about Star Trek will become realized. Sure, hyposprays and personal communicators were depicted decades before their invention on this show, but their cleverness has limits and I don't ever expect anything like warp drive, transporters, or hand-phasers will ever become a reality.

I believe that if traveling to the past without the alternate universe theory, paradoxes still won't happen. Events such as killing your own grandfather would cancel each other out. If you kill your own grandfather, you wouldn't have begone to exist in the first place, so you couldn't have tried to kill him.

Other than that, the alternate universe theory during time travel doesn't make much sense. At exactly what point do you pass from your universe to another? How do you get back?

There are no answers to this other than speculation... not enough about time is known. For instance, the psychological arrow could be completely subjective...

No. How I see it. If you are born, you are already secured from that paradox. If you were to came back in time and kill your parents, you wouldn't be able to be born to do that in the first place. Because stuff like this creates paradoxes, no one who will be born will kill go back in time to kill his parent. The paradox presupposes that someone would try to do that, when in reality, he couldn't.

Argh, I don't see a way to explain my thoughts on his clearly. I's hard to explain with words the scenario I have in my head.

Other than that, the alternate universe theory during time travel doesn't make much sense. At exactly what point do you pass from your universe to another? How do you get back?

I hate stuff that is unanswerable like this.

If you travel faster than the speed of light you'd go back in time, which is still considered impossible correct? but is that necessarily true for warping space time itself? If the time itself was bending around you rather than you speeding through space time wouldn't there be a different effect? and possibly one where you can move through space without arriving in the past or in the future?

I think I remember that. Only watched the first few episodes. Probably. It's certainly closer to a reality now than it was.

No, if you travel faster than the speed of light, you go forward in time, relative to your starting point (actually, you move through linear time at an accelerated rate, as compared to the place from where you left at that speed).

And, everything with matter bends space/time (the Earth's shape fluctuates at the poles and time is infinitesimally faster or slower with each contraction/expanion of the planet). This "bending" accounts for the force we call gravity. What you're talking about, though, would be an artificial, extreme example of this and would require generating the power equivalent to a black hole. I don't quite think we're there yet...or that we will be in the next 2000 years.

You move through time at an accelerated rate as you approach C. If you theoretically got to C then time would come to a standstill around you. There is no travelling faster than light and if there was it would mean going backwards in time. However if you warped space-time itself then the speed limit of the universe wouldn't necessarily apply to you.

Speed also plays a role in the rate at which we experience time. Time passes more slowly the closer you approach the unbreakable cosmic speed limit we call the speed of light. For instance, the hands of a clock in a speeding train move more slowly than those of a stationary clock. A human passenger wouldn't feel the difference, but at the end of the trip the speeding clock would be slowed by billionths of a second. If such a train could attain 99.999 percent of light speed, only one year would pass onboard for every 223 years back at the train station.

That's the twins' paradox... the relativistic effects, if I'm not mistaken, are inverse as you pass the speed of light. Allow me to demonstrate:

Let's say you take a spaceship to Mars, set up a telescope aimed at Earth, and then return home. You then decide to travel at warpspeed to Mars and look through the telescope. What do you see?

At a few light minutes away, you will go to your telescope and observe yourself still on Earth. In essence, you will be in the past. If you travel at warp speed to the edge of the universe, you will arrive at the big bang.

At a few light minutes away, you will go to your telescope and observe yourself still on Earth. In essence, you will be in the past. If you travel at warp speed to the edge of the universe, you will arrive at the big bang.

there's a good anime mini-movie called "Voice of a distance star" that explores this phenomena. Its about a girl who goes into space to fight alien invaders. The ship is travelling near light speed so she remains young as the guy she knows grows older. They exchange messages to one another, and the messages take awhile to reach one another due to the far distance from one another.
