One shuttle flight left, and we sent 2 billion dollars worth equipment to "find" Antimatter / Darkmatter? why?
What matters is to go to the other planets, and maybe send colonies there, what doesn't matter is "antimatter" at this point. Are we planning to build a warp drive?
Here is what I don't understand with scientists mind, they want to find out the origin of the universe... to prove what?
Some people might think that 2 billion bucks could be used for better things on earth, I think that 2 billion could be used to find better ways to travel in space, other than shuttle.
Why are we all doing things in wrong order always? |

It sounds like you're Anti-antimatter.

It's not that no one's working on the problem of long-term space flight, it's just that the technical hurdles are huge and the cost is, pardon the pun, astronomical. While the prospect of human space-flight to other planets is attractive, we *have* to do the cost-benefit analysis, and in fact, there is much bigger benefit in doing basic science. As far as planetary exploration, robotic probes are able to go places we as humans could never go, at tremendously lower cost, and thus are a better bet *today.*
Understanding the universe we live in is *the* key to accumulating the knowledge we will need to eventually break free of the limits of our single home planet. Think of it as building and constantly refining a model of a very complex system. We do not understand all of the physics of our universe, and some of the key answers lie in the nature of dark matter and dark energy.

These experiments will be another piece in the puzzle of the basic structure of our existence. Physics has two very good theories, Einstein's relativity, and quantum mechanics. Relativity works well for large structures and quantum mechanics works very well for very small structures. Unfortunately they do not work well together. M-theory ties relativity and quantum mechanics together with some very interesting conclusions; that there are many other dimensions in our world, at least eleven. M-theory also allows for parallel universes, that may be able to interact with our universe through the unexplainably weak force of gravity.
What the purpose of, and what these other dimensions and universes consist of is very interesting to me. Nature doesn't seem to create spaces without purpose. Some have used evidence of spontaneous creation of universes as proof that God does not exist. For me, I find other dimensions and parallel universes as being consistent with the real possibility that God and Heaven exists close to us. It's no coincidence that some of the particles men are looking for are dubbed "The God Particle" or Higgs Boson.
Knowing the reality of our surroundings has had profound effects on the way we think and behave. It is has allowed us to take these initial steps into space. it is the nature of man to explore his surroundings and one of the primary reasons mankind has been so successful. It is a shame that the US has limited its plans for further manned space flight.
i have mixed feelings on the search for God. The prospects of finding further places that God truly exists fills me with hope, but I am mindful of the lessons of the tower of Babel. |

While in the 60s manned space flight for research purposes made sense, it doesn't now. The computational power that one filled a room is now available in a cellphone. Remote sensing is so much more efficient and risk free that initial exploration of remote space is the only reasonable choice. Not only is manning mars shots (and beyond) expensive and materials intensive, but the probability of safe return is slim. It is not heroic, but it is rational.
As far as what we explore, that is a whole different question. When we forged our dreams of space, we thought we understood the galaxy. Suns, planets, dust clouds that sort of stuff. Now we have discovered that those things we thought of as the universe only account for about 5% of the matter in the universe. 70% is dark energy, 25% is dark matter, and we have no idea what it really is. I for one don't mid a bit of research into the 95% of the universe we do not understand, rather than focusing on the 5% we do understand. |

There is no need to explore. The earth is flat, and that is that. : )
We even know very little about the oceans that surround us.
Robots do a great job in planetary research. The Mars Rover program is a great example.
 
The shuttle gets pretty bad fuel mileage during the first part of it's trip, but makes up for that as it orbits. Just the boosters are burning 11,000 lbs of propellant per second.

Escape velocity is a bitch. |

| That one trillion dollars just spent on that scavenger hunt, coulda probably bought a pimped out spaceship with a warp drive :) |

Finding sources of antimatter would certainly make any form of interstellar travel, whether FTL or slower, much easier. But, I doubt that's the plan in the immediate future.
Science has always been about discovery and observation. We prove theories by making observations. Therefore, in this case, scientists NEED something to observe.
The shuttle was not designed for exploration. It's intent is for ferrying loads into space. We're pretty much done doing that, so now they are being retired, so that we can fund exploratory vehicles.

For the warp drive we need negative matter not antimatter.

r_s(t)=\sqrt{(x-x_s(t))^2+y^2+z^2}
f(r_s)=\frac{\tanh(\sigma (r_s + R))-\tanh(\sigma (r_s - R))}{2 \tanh(\sigma R)}
That was exactly how did I calculated this :P |
