what about your wife point of view? I would like still to be able to sleep with my wife, if I will (ever) fly to the nearest star. dozens of years that it will take from her point of view, will make me attracted to my daughter instead :(

A trip to Mars...let alone Jupiter...wouldn't be great? :P :shock:

A trip anywhere might be good, but as for "Great", aside from being physically able to stand and observe first hand on another local planet or moon (which would be great given our current advances), being able to travel to other solar systems would be truly great. Lets face it, we probably won't find any other intelligent lifeforms in our own solar system apart from ourselves (assuming we are intelligent). :wink:

I'm working on turning myself into exotic muons and bosons, then I could be everywhere all at the same times!!!!! :shock:

Must go much faster than light speed, actually I doubt that would be even a good
indicator of the necessary speeds to gain reasonable intergalactic travel.

so how faster could it be?

Nah, it would take way too long.
Get a title, "Hitchhiker's Guide to a Galaxy", and read it a bit.

Definitely - I think that one book explains more about how the universe works than every textbook I have ever studied combined......

No, don't read it, we are all doomed anyway, what's the point, My powersource will be drained before I finish anyway. :cry:

Travelling Light Year Distances - Time is the problem

The problem is not the the light barrier, it is the time barrier.

Arguably, we're close now (ie. ~100 years) to being able to build a ship that could travel the galaxy indefinitely, albeit very slowly.

What we have to do is figure out how to live long enough for such a voyage to make any sense. Another poster said a similar thing-
Storm_norm wrote:If we are going to travel out of our galaxy and explore the galaxy then its not going to happen with our current "state of consciousness".
It'll be easier to engineer the body to last for one thousand years than to engineer a ship capable of travelling at anything close to light speed.

Maybe to build a colony of ships, each space being able to recycle 100 %.
The space ship will need to be an earth ship big enough to last for millions of years.

Send a million ships in a million directions.

Just like an oyster, send out 100,000 of eggs for a just a few to survive.

The journey may have a none return trip.

The energy pack will require to last for many many millions of years.

Maybe just a dream

There was an episode of Star Trek (TNG, or Voyager) that delt with this idea. The ship was refered to as a "Generational Ship". An interesting idea though.

The original Star Trek had an episode where a giant asteroid was hollowed out and had carried about 1,000 occupants for 100's of generations. (They didn't know they were in one).

Just think, if you had a long-range Star Trek transporter, it would take all day to get to Saturn and back. Nine years round trip to Alpha C. (Earth time), there's got to be a better way!
