Science fact thread

I'm a scientist, I'm into space and stuff, but I'm not a space stuff scientist.

"Space and stuff?" That's very dry scientific vocabulary there pox, not so sure it will be appreciated here.

Several years ago I started a "Space Exploration" thread in the General Discussion area, expecting some enthusiastic responses from like-minded SF-reading folks. It was based on the amazing Pathfinder robots on Mars.

Well, much to my shock and utter, utter disappointment, it seems that many of the posters here are of the "spend the money here on Earth" ignoramus types.

It seems like many members here would rather read about fictional space exploration then actually support the real thing. It still boggles my mind. I was actually quite ticked off about it and I nearly got banned for speaking my mind about the ignorance shown by many forum posters.

In fact, that thread is one of the reasons I don't bother posting here very much anymore, while there was plenty of stupidity revealed in the responses to my thread, very few folks displayed any vision or imagination.

I happen to think colonizing the Solar System and beyond is the destination and salvation of mankind.

On the other hand, lots of folks here are just full of absurd thinking: "we'll just pollute the moon". This place is pretty hopeless for any real discussion of the value of Space Exploration.

It's not out of ignorance, nor do we accept the tag, "ignoramus".

Some of us are disgusted with NASA and view it as just another government entity, bloated and ineffective, a place where defense contractors go to make some extra pocket change.

What's your vision for the future?

Some ridiculous notion of colonizing our solar system?
Whatever for?.. and where are we to get the money?.. in case you haven't been keeping up we're 14 Trillion dollars in debt, and counting.
When you say the destination is beyond the Solar System exactly what do you mean by that? The closest star is 4.3 light years away and scientists expect that it is not of the type to support organic life as we know it. Do you really think NASA is up to that heady task, building a spaceship that could be in transit for decades to a star system that probably doesn't support life. Using the Space Shuttle as a yardstick I wouldn't let NASA change the oil in my car much less colonize planets.


On the other hand, lots of folks here are just full of absurd thinking: "we'll just pollute the moon". This place is pretty hopeless for any real discussion of the value of Space Exploration.


What's on the Moon that has you so ga-ga?
We didn't go to the Moon to explore it or as some lofty endeavor to better humanity. It was more about political gamesmanship and beating the Soviets to the prize. When we finally arrived on the Moon one of the first things done was to plant a god damn flag in the ground.
 
I will say one thing about the phrase 'spend the money here on Earth'. Until they can process credit cards, accept wire transfers or have some method of taking cash like a register out there in the Solar System I am fairly certain that every dollar/yen/yuan/euro spent on space exploration is spent here on Earth.

People get paid salaries, companies manufacture parts and sell them to various agencies like NASA and all of this contributes to the tax base and GDP.

Now is NASA the best agency to manage space explorations? That is a different question, and one that I am not sure of. When I see reports from Casini or the Mars rovers I say yes. When I consider the mess that is the ISS and the Space Shuttle I say no.

Making it to the end of time is my RELIGION my friend. I have total total 'faith' that 4 billion years from now the tiny tiny little ripples I have put in the pond will contribute to some kind of meaninful vote at the end of the universe. It's that or we all die on a rock. We have used all the metals, and given that as far as I can see the universe is self organising for some reason then I take our responsibility to make it the whole way very very seriously. I expound this point regularly. I have plans of action, mostly based around "doing the best you can" so that when it all turns out all right (4 billion years from now) I will have been a help not a hindrance (I choose to believe).

Really, what system beats that for long term optimism. If the rapture happens and loads of believers get taken up then I guess we divvy up their goods and chattels and damn well carry on with my system, which I think is better anyway.

We'll change. We can't be organic in the timeframe of 4 billion years I expect. We do really have to get off this rock bigtime before we get Kessler Syndrome and use all the metals and basically end up buggered.

These are rational extrapolations for me, and they involve going to space. I do not have a better plan than the current silly one we follow. It is wasteful and has the wrong drivers, but I would not ever want to see it stopped. Something will evolve. That bit's not my problem. I'm not good enough for space science, just making holodecks.
 
wow, engineer bashing. How quaint.

Really shouldn't have bothered reading this thread. All it does it tempt me to write angry defensive diatribes rebutting others' rightly or wrongly held opinions.

Plus, someone starts a conversation on science and it gets bent into some kind of referendum on government spending, bureaucracy, the implied evils of big government, and NASA.

What was this thread supposed to be about, again?

--Brian.
 
I just watched an INCREDIBLE 2 minute transit of the ISS, which rose in the west as -2.3Mag orange light, and curved over SSW getting whiter and whiter. I DARE people not to be a little inspired.
 
ah sod 'em. people are allowed to be boring and old.... happens in the end...

personally I am currently buzzing and my head is full of space junk (hangover) and ISS.

OK, perhaps there is some hope for this place yet. Perhaps things have changed around here since that thread I started way back in 2004. I hope so, because some (not all) of the responses back then were hopelessly ignorant.
It's not out of ignorance, nor do we accept the tag, "ignoramus".

Some of us are disgusted with NASA and view it as just another government entity, bloated and ineffective, a place where defense contractors go to make some extra pocket change.

My use of the terms "ignorance" and "ignoramus" referred to my experience in that 2004 thread. It looks like you were not around here at that time. Neither was anyone else who has commented here on this thread, at least so far.

"Government entity, bloated and ineffective..." You'll have no problem convincing me that we don't need any more of those. I mistrust the Govt, and I sincerely believe we have too damn much of it now. I don't want to get any more political than that.

I will say that there are some things that Govt does do well, and so far at least, NASA is a shining example of that. Now I do believe there are plenty of problems of all types embedded at NASA. It is a Govt run bureaucracy after all. The point is NASA has set the foundation for humans in space. Only baby steps for sure, but there are literally countless scientific discoveries that can be credited to the folks at NASA.

Does NASA need reform? Absolutely. Let's try not to throw the baby out with the bathwater though, alright?

What's your vision for the future?

Some ridiculous notion of colonizing our solar system?

Oh boy, here we go again. This kind of statement is exactly what I meant when I said "shock and utter, utter disappointment." It's not that the statement is ignorant. Its that the statement comes from someone whom I assume is actually an SF fan. Someone who should know what is really meant by a term like "vision for the future".

Ridiculous notion of colonizing our solar system?
Arthur C Clarke. Larry Niven. Issac Asimov. Ian Banks. Do I really have to go on? All of these fine visionaries and outstanding authors would know exactly what I meant by this statement..."colonizing the Solar System and beyond is the destination and salvation of mankind."

Why exactly you think this idea is a "ridiculous notion" is hard for me to understand, especially coming from a fellow SF fan? I happen to think attitudes like that, if they are hard and fast ideas that are set in concrete, are actually a lot more ridiculous than my own attitude.

Whatever for?.. and where are we to get the money?.. in case you haven't been keeping up we're 14 Trillion dollars in debt, and counting.

There are literally thousands of reasons for humans to continue exploring space. I'll give you just two here, but probably the two most important:

Energy- All the power humans could ever need is just 200 miles away, above our atmosphere, in the form of solar radiation. We need to get UP there to get it though.

Survival- All our DNA eggs are in this one basket here on Earth. The next time some asteroid or comet falls into an orbit intersecting with Earth, I want us to be able to do something about it. Or we go the same way the dinosaurs went out.

The money. Hell yeah, we don't have it or at least the Govt. doesn't. Does that mean we should just give up on Space Exploration? Hell no. Now that NASA and others have taken the first baby steps, other entities, commercial interests, perhaps coalitions with many other countries sharing the load, can build upon what NASA has learned and push forward.

Think long term here Sparrow. You are thinking short term and therefore can't see the forest because all the trees are in the way. :D

When you say the destination is beyond the Solar System exactly what do you mean by that? The closest star is 4.3 light years away and scientists expect that it is not of the type to support organic life as we know it. Do you really think NASA is up to that heady task, building a spaceship that could be in transit for decades to a star system that probably doesn't support life. Using the Space Shuttle as a yardstick I wouldn't let NASA change the oil in my car much less colonize planets.

I said our destiny ,not "destination" and there is a world of difference between the terms. I think I've given you at least a sense of what I mean by our destiny in my answers so far.

Yes the stars are a long, long way from us. Does that mean that we should never ever attempt to even try to reach them? Yes of course not next year, but how about 10 years from now? 25 years? 50 years? 200 years from now? You might say we''ll never make it that far. Well, we sure as hell will not make it that far if we don't solve problems like energy generation, or we get nailed by a comet. Which just helps prove my point that colonizing the Solar System and beyond is the destination and salvation of mankind.

Bashing the Space Shuttle is getting tiresome as well. Yes, there are many flaws, I agree with the points made here about that system. Still, I think the science gained through the over 100 Missions of the Space Shuttle more then outweigh the Shuttles' many shortcomings. Hubble is just one outstanding example of the type of science I mean.

What's on the Moon that has you so ga-ga?
We didn't go to the Moon to explore it or as some lofty endeavor to better humanity. It was more about political gamesmanship and beating the Soviets to the prize. When we finally arrived on the Moon one of the first things done was to plant a god damn flag in the ground.

Again, very shortsighted opinion here, Sparrow, disappointing really. Is that really all you think we did while we were on the moon? Sure there was some political gamesmanship there, but we gained a lot of knowledge about the moon and Earth from those missions. I've gone on long enough here, but if you do just a tiny amount of research, you will discover that we gained a lot of scientific knowledge from those moon missions. Certainly a lot more value to those Apollo landings then just the mundane planting of a flag...

what's the attitude we'd most like to carry forward, right to Tipler's Omega Point (or whatever it is beyond the information horizon), assuming we can?

Assuming it's not all for nothing.

This is why I read sci-fi. I'm on this forum to find the last bits I've not read. This thread is a little sideplay, but I certainly didn't expect to see science belittled. People just do the best they can on the whole.... It's not a lost cause so by inference we're doing pretty well!
 
Mass transport

Well, not to bring the discussion down to practical stuff, but

Thanks to PBS & NOVA, two links:

Advanced Weapons Elevator - basically a maglev train turned vertical.
http://military.federalequipment.com/node/60

Delivery is two years out, per their web page.

Turns out that the Burj Dubai at 828 meters is about the max for a standard cable elevator, (they use skylobbies like the WTC, so the elevator runs 515 m max) --these maglev things have no technical height limits, but probably are a lot heavier with all the magnets.

Of course in human factors, they still probably can't descend at faster than 8 meters / second.

And on another scale,

Space Elevator -- a less explosive means of getting stuff into space.

I for one gotta wonder how they're going to handle atmospheric drag, but I presume those folks are "on that."

Thanks for those links Brian. Those are exactly the types of responses I was hoping for in 2004. Really did not get enough replies like yours back then.

pox- You're starting to lose me. Omega Point? Is that like the "singularity" from Peter F Hamilton's The Dreaming Void? :D

I'm not sure humans are going to be able to develop quite that level of "technology? "entitity"? without help from the Galactic Federation of super-advanced alien races.:D

Unless the idea is to explore space and discover the "Omega Point" already in full operation? That is kind of what happens in Hamilton's trilogy, though I have not read The Evolutionary Void yet to find out whether humanity passed the "singularity's" audition yet.

Almost forgot I have some links of my own to add.

This article was just published yesterday:

NASA's Fermi Telescope Finds Giant Structure in our Galaxy


NASA's Fermi Gamma-ray Space Telescope has unveiled a previously unseen structure centered in the Milky Way. The feature spans 50,000 light-years and may be the remnant of an eruption from a supersized black hole at the center of our galaxy....

http://www.nasa.gov/mission_pages/GLAST/news/new-structure.html

Now this is really cool. A zoom-able image of the Hubble Deep Field. Just astonishing to zoom around and explore different portions of this one for awhile and realize what a vast and wondrous universe we inhabit:

http://home.exetel.com.au/bmgoau/space/008_1561b2.html

Here is a really cool video on the Hubble Deep Field, which some people have called the most important image ever taken:

http://www.youtube.com/watch?v=oAVjF_7ensg&feature=channel

And if that's not enough, here is a American Museum of Natural History video on the size of the known universe:

http://www.youtube.com/watch?v=17jymDn0W6U

Phew, thats a lot of great science that the Space Shuttle has played a very important role in bringing us. :)
 
yeah I've been watching all the crazy videos of enthusiastic geeky engineers peering into the middle distance at their helium suspended carbon tethers and laser climbers for some time.... nice stuff for sure but you look at them, and then you look at the numbers involved (the distances, the base diameter, the material strengths) and it starts to look like a problem we'll not personally see resolved.

I hold out hope though.

NeonKnight, without wishing to sound patronising

;)

I'm talking about a different thing. I just mean some progeny of ours lasting 4 billion years. Sci-fi probably will be wide of the mark as to the how on that really... I have to be honest with myself, I have no idea. I will never know, but I choose to proceed under the assumption that my actions matter.

Is that supposed to be your idea of "without sounding patronizing"? :rolleyes:
( Better spelling skills would only help your case, BTW.)

But your wink lets me know its all in good humor, so thanks for the "Tipler". A simple link would have sufficed. :D

I guess you did not read the Hamilton books. Because Tipler's Omega Point sure sounds one hell of a lot like the alien "singularity" in the Void trilogy.

I see where you are coming from. However, the fact that Michael Shermer, someone I have developed respect for, has issues with this idea, is not a good sign.

I do think we should be thinking long term, but 4 billion years? Not that long.
 
pushing the envelope of material science.

Pox - I figure the space elevator is more or less exactly that - derive what you to build one based on theory, then try to push the material science to give you the strengths and sizes you need, then reiterate.

Now if people were going to ride it, that could get amusing, either the elevator would have to have a bathroom, or you'd have to take your colostomy bag with you, and a few bottles of water, a few books, maybe a flat panel screen in the elevator built in, and chairs, of course, comfy chairs. And a few bag lunches. Now imagine running out of toilet paper half-way up.

"Um, guys? Is everyone done with page twelve by now?"

It was a "for instance" with an immediate caveat of "or what ever" and "totally unsure" designed to set the tone and no more.

Since I do not share your opinion, not in the least, then those colorful terms apply to me too. How about you stop using them.

"Government entity, bloated and ineffective..." You'll have no problem convincing me that we don't need any more of those. I mistrust the Govt, and I sincerely believe we have too damn much of it now. I don't want to get any more political than that.

Well that's just too bad, since NASA is a government entity, and it is bloated and ineffective, you best not expect big things from them.

I will say that there are some things that Govt does do well, and so far at least, NASA is a shining example of that. Now I do believe there are plenty of problems of all types embedded at NASA. It is a Govt run bureaucracy after all. The point is NASA has set the foundation for humans in space. Only baby steps for sure, but there are literally countless scientific discoveries that can be credited to the folks at NASA.

No not quite, the number of scientific discoveries the folks at NASA have made fall well shy of "countless". Many discoveries/advancements/wizbang engineering attributed to NASA were actually made by individuals and teams working for private companies under contract with NASA.


Oh boy, here we go again. This kind of statement is exactly what I meant when I said "shock and utter, utter disappointment." It's not that the statement is ignorant. Its that the statement comes from someone whom I assume is actually an SF fan. Someone who should know what is really meant by a term like "vision for the future".

Since when does being a SF fan give someone extra street cred when it comes to invisioning what the future might be like? Some of the most absolutely ridiculous predictions of the future have come from SF writers.

Ridiculous notion of colonizing our solar system? Arthur C Clarke. Larry Niven. Issac Asimov. Ian Banks. Do I really have to go on? All of these fine visionaries and outstanding authors would know exactly what I meant by this statement..."colonizing the Solar System and beyond is the destination and salvation of mankind."

Visionaries, are you joking?
Just because a writer waves his magic wand and creates FTL travel, though the physical laws of this universe won't allow accelerating an object to light speed, does not make them, visionary. Using wormholes, time travel, and other nonsense to tell a story is simply that, storytelling. If those elements don't exist, if they are impossible, then there is no vision, only entertainment not to be taken too seriously.
Now if we want to talk about having a keen eye toward the future let's talk about writers such as George Orwell and William Gibson.

Why exactly you think this idea is a "ridiculous notion" is hard for me to understand, especially coming from a fellow SF fan? I happen to think attitudes like that, if they are hard and fast ideas that are set in concrete, are actually a lot more ridiculous than my own attitude.

I'll let Charles Stross tell you why your ideas about colonizing space, specifically deep space and planets circling distant stars, hit the very heights of ridiculous. Charles Stross, SF author and visionary, and his High Frontier, Redux...

http://www.antipope.org/charlie/blog-static/2007/06/the-high-frontier-redux.html



There are literally thousands of reasons for humans to continue exploring space. I'll give you just two here, but probably the two most important:

Energy- All the power humans could ever need is just 200 miles away, above our atmosphere, in the form of solar radiation. We need to get UP there to get it though.

And what, process it and then beam it down to Earth?.. what?
We can already use solar power, right down here on the ground.
No need for NASA to build us an insanely expensive spaceship.

Survival- All our DNA eggs are in this one basket here on Earth. The next time some asteroid or comet falls into an orbit intersecting with Earth, I want us to be able to do something about it. Or we go the same way the dinosaurs went out.

We already have most of the technology required to do something about it.
Locate the wayward asteroid/comet and divert it from our path... or send Bruce Willis up there with a ragtag bunch of misfits, and blow it up. (joking)

Your idea of scattering ourselves amongst our sister planets, or goodness forbid, colonizing planets several light years away, is one of the most absurd reactions to what is a very real threat... "an asteroid might end all life on Earth"... so instead of doing the most logical thing, make sure you don't get caught sleeping by setting up a system by which you discover an asteroid in plenty of time... which btw already exists... and go about diverting it's trajectory... which we currently only have some good ideas... you think it is more visionary to fly nonexistent spaceships to worlds yet undiscovered many light years away?

The money. Hell yeah, we don't have it or at least the Govt. doesn't. Does that mean we should just give up on Space Exploration? Hell no. Now that NASA and others have taken the first baby steps, other entities, commercial interests, perhaps coalitions with many other countries sharing the load, can build upon what NASA has learned and push forward.

Push forward where, and to do what?

Think long term here Sparrow. You are thinking short term and therefore can't see the forest because all the trees are in the way. :D

When you no longer appreciate the trees you have no right to the forest.


Yes the stars are a long, long way from us. Does that mean that we should never ever attempt to even try to reach them? Yes of course not next year, but how about 10 years from now? 25 years? 50 years? 200 years from now? You might say we''ll never make it that far. Well, we sure as hell will not make it that far if we don't solve problems like energy generation, or we get nailed by a comet. Which just helps prove my point that colonizing the Solar System and beyond is the destination and salvation of mankind.

We are thinking animals, not particularly special in the scheme of things, because there is no scheme of things. We throw terms around like salvation and destiny as if the laws of nature will grant us a reprieve. We are traveling down the same road every creature that has ever lived goes, it ends in extinction. Perhaps not the most romantic of distinations, but it's ours just the same.


Again, very shortsighted opinion here, Sparrow, disappointing really. Is that really all you think we did while we were on the moon? Sure there was some political gamesmanship there, but we gained a lot of knowledge about the moon and Earth from those missions.

I don't have anything against going to the Moon when we did.
It's just about everything NASA has done since that time that has me bugged.

I think there's a solid case for shaking up their protectionist model of doing things. There has to be a whole swathe of new international agreements in place before the private sector gets involved though. Complex and interesting times. I love it.

I know it's the done thing to get all entrenched in threads and argue 'till someone breaks godwins law, but all this is ruining my science buzz thread!

If you want to apply the terms to yourself, well that's your choice isn't it?

Sorry, not going to bother replying to the rest of your post. It would obviously be a complete waste of time. We'll just end up talking past each other anyway.

Peace

:D Oh good you did read The Void! As I said, I have not read the finale. Without revealing any secrets of The Evolutionary Void, in your opinion, is there any similarity between the "singularity" and "Tipler's Omega Point"?
(My guess would be no, but I thought I'd ask anyway.)

Capone incident? I immediately thought of Gerald Rivera! (But that can't be right. Can it?)

It was a "for instance" with an immediate caveat of "or what ever" and "totally unsure" designed to set the tone and no more.

I like it! :D

After I posted that, I realized you might be a Brit, pox. I guess it is just one more case of a the US and the UK- two countries separated by a common language. :D

Probably the same language that allows such nonsense as a type of road where one drives very quickly can be known as a "parkway" while the piece of road where one leaves the car overnight is known as a "driveway"...
