if the fuel was contained inside the rocket it wouldn't be moving. it only moves because the energy the fuel creates pushes off against the ground, and to push off it needs to exit the rocket
I don't think space travel would be possible unless we found some super high-energy efficient energy source, because with what we have now, it doesn't seem like it would be sustainable over periods of years.
It also doesn't solve the problem of that we can't get anywhere past the speed of light, since if any matter where to travel the speed of light, a division by zero would occur in this equation:
That means you need an infinite amount of energy to get matter to travel the speed of light.
In order to go from point A to point B without the use of something like a wormhole, you need to go very fast to get from A to B within a human lifetime if the distance between the two points is something like the distance from our solar system to the nearest star.

There's some interesting theories on bending space.
Anyway, if/when nuclear fusion starts being a viable technology, then we have the huge energy source we need. The trick is using the energy to move ships around.

Alpha Centauri is about 4 light years away. While true that it'd probably take a ship moving 99% c 5 years to get there, only about 6 months would pass onboard. A ship with a single generation can go a lot further than you'd think. It'd feel like under a year to get to Sirius, 15 months for Tau Ceti, etc.
@Original post. aside from the facts that this would not move a ship without loss, you'd get more propulsion by simply using the solar energy. Furthermore, how much solar energy do you think a ship is getting half a lightyear from the nearest star?
I think a better method of getting energy is the use of laser beams.

The laser beams will compress a hollow shell filled with the hydrogen isotopes deuterium and tritium to up to 100 times the density of lead. In the resulting conditions – temperatures of more than 100 million degrees Celsius and pressures as much as 100 billion times the Earth's atmosphere – the fuel core will ignite and thermonuclear burn will quickly spread through the compressed fuel, releasing many times more energy than the amount deposited by the laser beams.

Assuming you can reach near speed of light speeds.
I'm still thinking the only way to get to Alpha Centauri and back within a human liftetime would be via wormholes, because there isn't really a plausible method that is realistic which will get someone there and back, yet, without wormholes.
You guys are mean, I don't know how sustainable or safe that would be. It's not like we can just move a nuclear reactor around on a spaceship with us, can we?!

Yes, some strange things happen when you start to approach the speed of light. Unfortunately the highest speed that a starship design could reach without venturing into the highly theoretical, would be about 0.1c, using the 'drop nukes behind the ship' method I mentioned. That was not a joke - I wrote about it here: http://www.staredit.net/175704/

Did you honestly just say that wormholes were more plausible than simply going really, really fast?

He's saying that its more plausible in the span of each party's lifetime. Time dilation is a bitch approaching the speed of light.

Uh, I believe they DID put a whole bunch of nuclear reactors into some of the space probes. It should be possible to do it with humans onboard as well. However a better power source would be nuclear fusion, thanks to low radiation. UNFORTUNATELY nuclear fusion isn't useable yet for a power source.

Yeah I'm not a big fan of Westernhagen either, Fanta vier much better! But they didn't drop the lyrics that fit the situation. Farty: Ich bin wieder hier; nobody: in meinem Revier; Me: war nie wirklich weg
