Still, Mars is uninhabitable. Why do we care to set foot on there?
Um, to start a colony. The only reason they've ever talked about going there.
Yeah, but as I said, right now it's not livable. It was designed to be lived on by humans.
I don't think I follow this sentence? What was designed for humans?
I think the biggest reason of going to Mars is that we can develop technologies to better harness the resources that are available on other celestial bodies.
My biggest thing right now is why are we so focused on getting to Mars when we haven't made a livable colony on the moon? It would be the safer bet and a logical stepping stone to getting to Mars. It would also be a proving ground for said technologies, especially with the resources that are readily available on the moon for us to exploit (Helium3?)
snicker the Nazi's are already there...wait...that might be a movie, not a documentary...lol

If you've never been on that tour at EPCOT, it's a really neat sight. I went earlier this year.
The boat tour is great but the walking tour is even better. I've done the tour easily half a dozen times since I first did it in 1998. It's my favourite thing in Disney World. We've taken the tour given by researchers and even the PhD who headed the entire facility personally (he was so excited to show off their research, it was awesome.)
That tour inspired me to build a collection of all of the major academic texts on hydroponic crop production. I've read about it extensively, more than most ag majors would ever see, even at graduate level.
Done both same day. Did the walking tour last year.

@Bill-Kindle so much fun and so educational!

Think of Christopher Columbus and discovery of the New World.. Where would we Americans be had he not ventured into the unknown and the dangerous waters of monsters and myth.
We'd be living in Europe without the weight of the guilt of exploration through genocide
Well, I don't like Europe and I have no weight of guilt over some genocide that happened 400 years ago.

Yeah, it was absolutely crazy and terrifying.
Which is why (at least I think) the phrase "Flying by the seat of your pants" was coined....
Long / Deep space exploration is impractical because of the amount of fuel, water and Oxygen that would need to be bottled and hauled with. You'd have to build a Bio-sphere type system.. a 'Mini Earth'
But I'm no rocket scientist..
...not to mention the real distances you're talking about. Our movies today have our minds so misguided in terms of what deep space is really like. All of these Star Trek images of hopping around different galaxies is absolutely ridiculous. The Milky Way is about 100,000 light years across, and we're about 26,000 light years from the edge. That means that you could travel at light speed for 25,000 years and not reach the edge. Our recorded history is roughly 6,000 years. It would take almost 5 times that at light-speed travel just to get to the closest exit from our galaxy (of course, that's edge-on)! So, unless we can figure out how to go thousands of times faster than light speed, or learn how to create wormholes (which, of course are only theoretical to begin with) with known locations on either end, the whole ball of wax is kind of absurd. But don't let facts and logic throw you off course.

....and yet there are those people who think they can build the Starship Enterprise....granted without warp drive...

Manned flight was ridiculous back before December 17, 1903 too
What makes something seem ridiculous to our knowledge now could in fact become reality in the future. -

We're talking about moving much, much faster than anything in the known universe is capable of doing. That's a little bit different.

People used to think that traveling at speeds would stop you from breathing too. http://www.historyextra.com/railway
"Thundering along at previously unimaginable speeds, early steam locomotives were a frightening prospect for their Victorian passengers. Before the opening of the first major railway line, the Liverpool & Manchester in 1830, there were fears it would be impossible to breathe while travelling at such a velocity, or that the passengers’ eyes would be damaged by having to adjust to the motion." -
Yes, I get that. Still it has nothing to do with this discussion. We have a pretty good understanding of the world around us today. That was not the case 150 years ago. I'm sure we think we know some things that will be proven wrong years from now. At one time the world was flat (not everyone believed that, but it was the prevailing theory of its time). I'm sure we have something we believe firmly that will be proven false with better information. That being said, what does any of that have to do with the speed of light? Teleportation is within the realm of becoming a reality. Bionic implants and the like are on the doorstep. Cloaking devices, too. Cold fusion is even in the news again. Still, what do we know of that can travel faster than light? Oh yeah... nothing. The fundamental concepts on which modern physics is built doesn't leave much hope for travel beyond light-speed. But that's not even my point. We're not talking about going faster than light. We're talking about going thousands of times faster than light. Unless you have some pixie dust up your sleeve, I don't see that as worth even discussing, at least not in any kind of constructive way.

You're making my point now. What we know today can be bunk tomorrow.
I'm sorry for upsetting people, I feel like I"ve upset the apple cart.

No harm done. I agree with that point, but I also don't believe it has much relevance with the magnitude by which we can't approach the limiting factor. A little off, sure. Thousands of times? I just can't take that seriously as a "well, I'm sure we'll have that figured out in a couple years" sort of thing.
