If we could find a better way of propulsion and could get to different planets it's possible that we could in the next few hundred years actually set foot on another planet. Think about that. I won't be around to see it but how cool?

With our current speed limit it would take us like 10-20 years just to get out of the solar system.

I disagree with this. With the moon we run into the facts that:

  1. Been there. Done that.
  2. It's only rocks, anyway.
Disregarding the fact that both of these statements are amazingly short-sighted and wrong, it is the commonly held belief by the people with whom we need to convince - i.e. Congressmen. But they are too busy trying to become wealthier and to kowtow to their constituents (and by that I mean the business interests who have purchased their votes).

But a new planet with the possibility of sustaining life and possibly having abundant minerals or new items to discover? Well, sir, now you are talking!

Not to be a party-pooper, but reading the article on the details of the planet, we're looking at:

-twice Earth's gravity
-perpetual murky red twilight on one side of the planet
-nothing but night on the other side, because this planet apparently has one side always facing its sun and the other facing away
-nothing about land mass, just water so far
-mostly CO2 atmosphere, in which we would suffocate

Still, for me it'd be exciting just to find out about animal or plant life on another planet.

Hey Congress! Stop being fuckwits and FUND THIS SHIT!
Are you on crack? Do you know how far 20 LY is? The fastest manned flight ever was Apollo 10 @ like 24k mph it would take a half million years to get there. Even at 1000x THAT speed 24 million miles an hour ( which is 3.5% the speed of light) it would take like 550 years. We will NOT be able to travel at even double Apollo 10 within 2-3 generations with out killing people due to acceleration G forces, unless some majorly, majorly, MAJORLY HUGE fundamental physics findings are made in the near future. I'm talking about as major a leap as it was to get from alchemy to quantum physics. We are no where near understanding how the universe (or even gravity) works for that matter, and the universe is a HUGE place.

Just as a reminder: Take an ordinary light bulb and pretend it is a scale model of the Sun. The earth is the size of a dot next to it, and the scaled orbit of the Earth is 30 feet -and that's just 1 AU. The entire solar system would be the size of a football field. It's almost dumbfounding how small we are.

You really need to work in the field of science to fully understand how many questions have top people in their respective fields scratching their heads. It really is grasping in the dark a lot of the time. I'm a very Socratic thinker in regard to science. For all that we know, we don't know shit.

I know that mankind has progressed technologically at an amazing pace, but I'd give inner stellar travel at least another 1000 years. What you're saying is analogous to someone in 2 A.D. saying we'll be able to create flying machines in the next 1o0 years.

Any feasible manned inner and extra solar travel (like Mars) will have to involve launching from the moon with current technology. Before we can even think of inter stellar travel, we need to be able to colonize in orbit around our planet, the Moon, Mars, and possibly Jovian moons. I don't think you appreciate just how hard it is for NASA to just launch the Space Shuttle and coordinate unmanned space exploration. Rocket science ain't easy like brain surgery.

20 light years is ~ 117,569,996,000,000 miles.

That is, roughly one hundred seventeen and a half TRILLION miles.

Can't exactly hop in the prius and drive there on a weekend.

The distance to the moon is about 240,000 miles.

It took Apollo 11 around 4 and a half days to get to the moon. Let's be nice and round it off to four. That would mean it covered about 60k miles a day (my dad's station wagon looks on in envy).

That means, at current propulsion levels (and I don't think we travel a whole lot faster in space these days), it would take about 1,959,499,933 days to get there.

1.9 billion days. Hard to wrap your head around a number so big. Maybe if we switch to years...

5,368,492 years. Five point three six eight MILLION years.

You know what happened even around 3 million years ago?

Homo erectus.

It would take us longer to get there than OUR ENTIRE SPECIES HAS EXISTED TO THIS POINT.

Your grand, or great grand, or great great grandchildren will NOT be colonizing this planet. We stand a better chance of terraforming a planet in our own solar system before we reach this one, unless there's a sudden breakthrough in space folding.

See, I know the math. I also know that currently it would take a couple hundred THOUSAND years to get there. But that's using current technology and not gaining any new. What I'm saying is that this is the perfect carrot to put on the stick for the politicians to refund the space program.

A couple hundred thousand at current? Gasbandit's plugging us at 5 million years at current. That's a big difference as to whether it would even be possible in any way.

Like I said I don't think the tech is going to advance enough to ever see it happen in our lifetime. Manipulating space-time and gravity is a mighty leap. To be honest right now, it's like a caveman trying to build a computer.

The distance to that solar system is 1.18 x 10^14 miles. Traveling at a velocity of ~24,000 mph (24791 mph to be exact) of Apollo 10, the fasted manned velocity to date = 4.76 x10^9 hours or 1.98 x 10^8 Earth days or 543,355.2 Earth years.

That means, at current propulsion levels (and I don't think we travel a whole lot faster in space these days)
Actually, we can travel faster in space these days, or could if we just threw enough money at the issue. If we really wanted to we could get up to speeds much faster than were used to get the moon, but it would either involve high risk or lots of money/resources (just build a bigger ship that carries more fuel and accelerate longer). There are also various propulsion systems that are in development that promise to provide much more efficient propulsion as well, without the great risk (nuclear pulse propulsion) or cost (conventional chemical propulsion). If ion propulsion pans out it will be roughly 10 times the efficiency of chemical propellants.

If we did build a ship to go to another star, it would be going faster than when we went to the moon.

Yeah except it'll take a whole shitload of fuel and a shit load of time to accelerate at levels low enough not to kill a person. Realistically you can't have a person even doing 2 g's for like 10 years.

What I'm hoping is that biotech and physics advances enough that we can simply upload our very consciousness into a collective thought "cloud", and manipulate it somehow as an EM signal. Then (according to relativity), if your conscious mind is zipping around as a light particle you'll pretty much be able to experience anywhere you want to go in an instant; possibly upload your conscious mind in a body 1 billion light years away. Of course, in the mean time, on Earth, your "lifeless" body will sit around relative to observers for a billion years or so. Really, I think that's going to be the secret to the immortality of humanity (if we even make it to that point). The whole concept raises tons of questions fundamentally to the point of what it even means to be human.

And, no, you assholes can't steal this as a novel plot device. I'm already well on my way using it in my own sci fi novel. :unibrow:

I'm not saying that the difference is enough to make the trip feasible, just that Gas's assumptions that we can't travel faster than we did to the moon are wrong.

Well, I think he was referencing current manned space flight. But that's why I included a further example for my model. Even if you could Jimmy a way to go 1000x faster than Apollo 10, you'd still require 550 years to get there. You'd essentially need a self-sustained ark for that kind of trip. Remember 550 years is a long time too. 550 years ago, the Ottoman empire was in full swing taking over most of the civilized world.

I remember reading about nuclear pulse propulsion in Footfall, published in 1985. Granted, it wasn't used to travel to Jupiter, but it did power the craft that fought off an invasion of evil elephants.

Saying anything like "current rate of tech development" or "caveman building a computer" is flawed, though. The underlying assumptions are that technology is one thread, and that it's monotonically increasing, neither of which is true. If you drew a graph of tech development in, say, sensor development, the chart would be all over the place. Radar would leap the curve ahead in the 40s by some monstrous amount, only to have the curve backtrack right after that.

Which, Mathias, brings me to a sci-fi story idea I've had: stop assuming all tech develops at the same rate. Have an alien race show up on earth with crudely engineered but highly advanced FTL engines, but horrible computer systems (if even present at all--maybe they navigate by eye). If you think that's impossible, look up some of the mechanical wonders from the time before computers took over all those tasks right here on earth.

In that movie, Clint Eastwood, Tommy Lee Jones and the other geezers were sent into space because there's a Russian satellite in need of repair that used stolen propulsion technology designed by Eastwood. The other engineers can't do anything because the tech is so old and the satellite is apparently essential to all Russian communications (though there's a rather stupid "twist" reason) so there's no choice but to send a bunch of old guys into space.
