Does anybody here think its possible?

Does anybody know of any decent websites or research sources? all I ever find is discovery channel style documentarys that are aimed at adults but spend an hour telling me "this is how we could travel in the future" que naff graphics of a spaceship.

Its pretty obvious we will never get to another star without one.

Some people say it sounds too much like a perpetual motion engine...... well earth magents look like a perpetual motion engine if you dont understand magnetism, so I dont agree with this argument.

There a theories as to how we can travel close to the speed of light, but not quite reach it. Either way, the amount of research and money that would need to go towards it would likely be a number of times higher then the ISS itself.

Sure going to other planets/solar systems/galaxies would be great, but it would take several hundred years before we get the technology to get that far.

2089 is the year to watch. Mark my words.

I'll be sure to wait around for that, then - not so sure I'll remember why ,,,

To OP, the way things are, we could already go to the stars - just it'd take a few thousands of years.

I think it's possible (I damn hope so, would get depressed if someone proved it impossible lol) but it will take a loong time unfortunately. We need something to speed it it up like a technological revolution or something like that.

It's not a technological revolution we need, but a much more advanced understanding of physical laws.

As it stands, it's not a technological barrier that prevents us from traveling faster than c, it's the fact that according to our best understanding of the laws of physics, it is impossible to do so, as it would violate causality.

Instead of wondering about a "space drive", we should put our efforts towards expanding out within the solar system, since that's at least theoretically possible.

Give us 100+ years and we will have allot more understanding.

[MikeGotTalentz]

Considering that even at the speed of light traveling to other galaxies would take forever, i think we´d be better off developing some kind of stasis or hypersleep technique first.

[herbalviagra]

Thats also the other thing, if we want to really travel to the stars and other galaxes we really have to find a way to go faster then light speed.

According to the theory of relativity, as you approach the speed of light, mass increases infinitely, meaning that you "slow down" as you speed up. Simply moving an object with mass at the speed of light violates the laws of physics, and it's not just a causality problem.

With the same understanding of physics, it is equally plausible that causality may not be broken. The observed magnitude of C is variable due to relativity, which means it is dependent on the medium it travels through. So travelling faster than the speed of light in a vacuum would cause a paradox; however, travelling in another medium for which speed of light is greater than it is in a vacuum would not.

My point being we could possibly travel faster than the observed speed of light as it travels between stars, and still not violate causality. And this is easily supported by our current scientific knowledge.

No, it only means it takes more (eventually infinite) energy to accelerate the mass, in a vacuum.

well theres such a thing as a Daedalus engine which uses nuclear explosions as a means of propulsion

but its very dirty and would irradiate everything in its path

In theory,
afaik it was never built.

Although to physically travil at the speed of light is impossible du to the fact that mass increases exponentially as speed increases, meaning as you approach the speed of light your mass approaches infinant mass, it is possible to travil distances faster than the speed of light by warping, bending and stretching the fabric of time/space. It has been an ongoing theroy since Einstiens theroy of general relativity that it is indeed possible to do so and would make traviling vast distances a matter of standing still while the space around you is pulled faster than the speed of light, which is entirely possible.

Except currently the only way we know to alter the "fabric" of space-time is the "bending" that represents mass.

And btw - not having 20 spelling mistakes per sentence makes it a great deal easier to read your post, and consider it worth replying to. Just saying...

Just do it like in Futurama...the Ship is stationary and moves the universe!

That would be cool and all, but what if you get two ships moving in opposite directions? The universe would split in two.

[njfeedd3w]

nah it would swirl like cream in black coffee

No it wouldnt as the two ships would be outside of space time
