dmpoole said:GordyR expressed it so much better than me except that I still don't accept interstellar travel. The cost of putting a ship into orbit and travelling 100 million light years (or less) would be astronomical and I still won't believe in faster than light speeds or shortcuts. Theres no bigger fan of Star Trek than me but its all bull.
My reasons for believing that interstellar travel will one day be possible, do stem from a kind a romanticism, I will readily admit that. I want to believe it, therefore I do.

However something that we must bare in mind is that we do not have a complete understanding of physics yet. In fact you could go so far as to say that our current undertsanding is likely extremely basic. Theories like M-theory go a long way towards giving us that unified theory but we are still very short of having a complete picture and of course M-Theory could also turn out to be the greatest scientific 'wild goose chase' in history, but that remains to be seen.
General Relativity gives us at least two ways of intersteller travel. One being wormholes as you are aware. I personally agree with you that it is highly unlikely that wormholes will ever be usable for interstellar travel. There are far too many factors like stability and the vast amounts of positive energy required, for me to ever consider it being a reality.
However General Relativity is not the be all and end all of physics. I think we need to look beyond it for the possibilities of intersteller travel.
A lot of the newer models of the universe paint a completely different cosmological picture of the universe. Within this framework there are possible loopholes around the whole faster than light problem with regards to travel. Superstring theory (or M-Theory) with it's requirement of 10 or 11 dimensions opens up a whole realm of theoretical possibilities for interstellar travel which at no point requires the interstellar craft to actually move faster than light.
Of course in terms of practicality we are an awfully long way off of ever putting this sort of thing in to practice. Though that could all change in the blink of an eye if certain discoveries get made soon.
Throughout history we have always set barriers for ourselves due to our limited understanding. Scientists at one point thought the notion of an aeroplane was absurd. But we have consistently broken these barriers as our understanding increases. This has happened time and time again throughout history so I assume that this will continue. I think thats a good enough reason not to completely rule out interstellar travel at some point in the future.

dmpoole said:The NASA footage is interesting but I personally agree with the explanations given that its ice debris and its probably on the windows. The space serpents are interesting and I wouldn't discount it. As I said earlier, I believe that life will find a way and I'm not an expert to say that nothing could live in temperatures that cold or in a vacuum.
The footage was interesting until they had to ruin it with plasma beams knocking out UFO's and teams sent out to pick up the debris for backward engineering and they've been doing it for decades. So basically, out there are millions of UFO's and America keep firing at them with a plasma beam - yeah OK. Darn those pesky Aliens - get the fly swatter out Dubba. Also these UFO/Aliens have got really boring lifes for intelligent beings/objects. Instead of flying into a circle and saying 'look we're here' why not fly closer to the shuttle and announce yourself?
The problem I have with Aliens is that they're so thick. They have the technology to travel hundreds of light years to this planet and then mess about hiding in back alleys, messing with cows and giving some of us an anal probing. They also turn cars off and stay in the sky for a while playing hide and seek. I'm pretty sure thats what we'll do when we find a living planet.
The rest of your post I heartily agree with. And I applaud your wording! I actually laughed out loud when you struck on "anal probing". Good post.
