we will never go but a toes dip in the water of space.

mankind needs new science.

we need new inventors and new entrependeurs with fresh radical ideas.

even if we get new ideas I doubt if the forces in power will allow them to see the light (pun) of day. conflict of interest.

please, some inventor prove me wrong ! and get er done.

Look NOM....new planetary potentials! biggrin.gif YaY!

Talking about a waste of time... try getting to one of these planets. cool.gif

Nuclear propulsion is the only way to get there. Think about it.

1lb nuclear fuel = 1,000,000lbs chemical fuel

It's not like nuclear energy is even that hard to use, either. Everybody is just terrified of it. Basically we are using junk technology in space, stuff from the 60's. Anybody wonder why it seems so hopeless?

Nuclear energy is of course not a solution.
Make a couple of calculations and you'll see it.

Thanks tikay.

I think the "new ideas" that holoman is suggesting will come from creative use of nanotechnology.

If general relativity holds, then the only sources of fuel / energy which can enable interstellar travel-and-return-in-one-lifetime are antimatter and light-beams-sails. Forget nuclear, insufficient energy-per-unit-mass by at least several orders of magnitude.

The numbers I've seen indicate that with hydrogen fusion it is barely possible to make an interstellar rocket. What it really takes is antimatter fuel.

Personally, I think the only practical way is to not carry the fuel with you at all.

I also think that solar sailing is very useful. That way you're not carrying your fuel with you (and so you're lighter). As well, Earth-based technologies can continue to improve and so they'll be able to bring new energies online while the ship is in flight (assuming the sail is being pushed by laser).

You'd be surprised at the source of 'new inventions'. Because of the compounding nature of research and technology, any new technologies that can be encouraged will speed the development of these breakthroughs. And new technologies require excellent education and "out of the box" thinking.

If you (generic you) want to help us get into space, the most useful thing you can do is to learn your sciences as well as you can. Then keep an eye open for places to invest or processes to improve. Even if your job is some "9-5 deskjob of uselessness" or some demeaning manual labour job, you still have opportunity to use your consumer dollars to encourage research and the opportunity to learn on the side. Inventions lead to more inventions. Investment leads to more investment.

An hour taking classes every night at University of California (Berkeley) will do a lot more than watching some sitcoms.

We need more people to push themselves for excellence. Cultural excellence will follow.

60's technology is not junk. Back then...we actually made and tested things properly. You think the latest and greatest is the best? Think again! Current mass technology is junk. Junk is always noticeable, because junk causes problems. Real technology is invisible almost, you press a button and things just work, and things just keep working flawlessly for a decade, without downtime! Nowadays, you have to be a programmer, tinker, mess with everything, reboot, answer a thousand questions, remember a million passwords and secret questions, and throw away your old gadget every few years. We have been misled that this is what real technology is. Wrong! Technology is like storm drains, we only notice it when its not working! (i.e. Flooding, backing up) That's because now "make as much junk as fast and as flashy as possible" to sell as fast as possible, and force people to spend by upgrading as fast as possible! Does this sound familiar, kind of like the US auto industry? We then "fight fires" by patching up problems that seem to blow up all the time, hmm big wonder. This is the nature of technology now, thanks to greed and profit as the bottom line. Ever wonder why your PC gets slow in 2 years, and that you always need a new one? Good technology doesn't need to be replaced all the time, only junk does, and good technology holds its value over time My HP 48G engineering calculator, despite being 15 years old, still is worth 80% of its new value! Marketing is king these days. Why is it that Windows still has the same basic fundamental problem from 1982, namely that files don't have hardware protection, which would have eliminated spyware, viruses, and most of our security issued back in 1982! Bricked iPhone anyone? Airbus A380 delayed 5 years? The list goes on and on...

My new laptop, now 2.5 years since my old one, which incidentally costs MORE new than my old lappy when new, can't do math faster than my old one. Yep thats right, running Windows Calc, it takes 15 seconds to do 40,000!, but my old one took 13 secs. Also, the new one boots slower, simple programs I used to use now are huge and slow.

Push a button, and it just works, thats how most things work in Japan. No programming, no thousand questions, no crash, no tinkering, and certainly no programming! Japanese have no time for junk or certainly not for programming, and thats why people don't use computers much there...they prefer locally designed cell phones and home electronics, even to surf the web, etc That's why Japan produces the best consumer technology, as they actually take the time to test things properly before shipping out the door, and make it so simple and error free a cave man can do it. However, for foreign markets they can't compete that way cuz the development cycle is too long and too slow, people don't upgrade, and the likes of Sony have seen their image tarnished as they changed and act just like the junk makers. Many companies though refuse to change, and that's why they are losing to fast cheap crap producers like China and the US software and web industry. A few, like Toyota, are examples of the long term payoff of making quality. The Swiss have been making quality watches for hundreds of years!

One day, we will all wake up and say, I don't want junk! We want it all seamless, flawless, and perfect and invisible! We want our city trains to run only 0.3 seconds late on average. We want 45 years of high speed rail without an fatal accident. We don't want to know that Caltrain, BART, and MUNI in the SF area are different systems, we want them integrated and seamless! Voyager and Pioneer spacecraft, produced in 1970's, still are working, sending data. They are not junk!

Mankind will never visit those planets, not even having been to the Moon. Here's the proof of the moon landings being an outrageous fake:

(No, seriously, I can't stand those nutters who say that we've never been to the moon, but this site is a little different... )

If you bought a PC that was two and a half years newer, but ran slower than your old one, then you clearly didn't know anything about what you were buying.

Computers are NOT appliances.

There is a reason they say Caveat Emptor.

Next time get someone to HELP you buy a machine that meets your needs.
