you missed my point... just because i say 1 space research is less important... doesn't mean all of them fall in the same category...

what i say... we need to focus the research on technology that will enable us to travel faster than light... if this is possible... only then, the search on suitable planet in our galaxy will be significance...

right now... scientist are talking about far away planet which has been discovered that MIGHT be able to support life. So far no solid prove, its all based on theory. Even if it is true, it will took thousand of light years to travel to that planet.

Back to the budget... with the current economy, budget has been cut. The question is... which research need to be focused on and which one that can hold. Everything is important... but some are be more important that the others.

We will never be able to travel faster than light. Nothing can travel faster than light. The only way to reach another destination ahead of light if both start from the same point is by using extreme curvature of spacetime caused by massive objects like a blackhole.

Idea of searching for other planets that may support our future need not depend on the ability to get in a short period of time. So what if it takes 10000 years to reach that destination. It is easier to build a huge spaceship that can support a thousand generations of humans than trying to beat the speed of light.

The theories behind fusion and cold fusion myth is pretty clear already. For fusion, its just that a critical self sustaining reaction have yet to be achieve, therefore fusion reactions so far resulted in NET LOSS of energy. Only successful fusion reactions which yielded a net gain would be in hydrogen bombs. Which is .... erm ...... not suitable if you want to harness energy.

There isn't any REAL theory on cold fusion. at all. only in fiction. yet ... biggrin.gif

was just reading about this, article questioned whether it would be ethical to 'condemn' your kids to being stuck in a tin can(as someone here put it) for the rest of their life(and their kids), never being to see greens and experience life on earth

anyway, this month's discover magazine(or was it next month, i dunno my college library sometimes get mags a week early), features space/space travel, very interesting read

Certainly motivation for such generation spanning travel will only arise when earth is no longer habitable. Surely it will then a matter of whether you get to fit everyone into such space ship.

Though I would consider it to be a privilege to be part of the pioneering humans when colonizing other planets.
