fallen of democracy champion...

maybe its better to spend more on earth protection... protection from pollution, meteor...

spending a lot for knowledge about something beyond our need is just a luxury that we might need to put aside for the time being...

I dont see why space research isnt important.

It's crucial for our survival.

yes... science is important to improve our life... there are many branches of science... even for space exploration... there is so many research going on where it cost billions... some of the research is necessary but some can be consider as luxury for this time...

not sure about other ppl... but for me... research like finding another planet that can support life in our galaxy seem to be unnecessary for the time being... eventhough if we know there are some suitable planet for human in out there... we still don't have the technology to go there... and actually transport human colony to live there...

this kind of research might be significance once we have discover the way to travel faster than the speed of light...

With this kind of thinking,then,we wont be able to advance in science.Everything we have today is just a step up from what we have yesterday.Things are improving step by step,not suddenly a huge leap to a new tech.

If we dont have ion engines now,how we gonna get an engine that travel in speed of light?

It's like trying to make a jump between steam engines to hydrogen powered electric cars.

you missed my point... just because i say 1 space research is less important... doesn't mean all of them fall in the same category...

what i say... we need to focus the research on technology that will enable us to travel faster than light... if this is possible... only then, the search on suitable planet in our galaxy will be significance...

right now... scientist are talking about far away planet which has been discovered that MIGHT be able to support life. So far no solid prove, its all based on theory. Even if it is true, it will took thousand of light years to travel to that planet.

Back to the budget... with the current economy, budget has been cut. The question is... which research need to be focused on and which one that can hold. Everything is important... but some are be more important that the others.

I was just using steam engines and hydrogen powered engines as an analogy.

If you want to focus on researching to travel at speed of light,why not start with ion engines first.If it works,go even faster.Things just dont happen over night like suddenly you have a light speed traveling capable engines and you just have jet engines yesterday.

I dont see why we shouldnt find a suitable planet now.Regardless on the economy.Firstly,it's always a human curiousity to find out whether there are life on other planets.The finding they have now could help us when the time comes for proper space travel like a map for the particular type of planets that they are looing for.

Researches are important,probably all of them,IMO,even for theoretical stuff like LHC as the findings from that could explains some of the mysteries of science and spawn new inventions.Or it's findings could help other fields like quantum computers to mature.

There is an alternative energy method, which is much superior than nuclear, and it doesn't emit radioactive wave. It's call fusion technology. The disadvantage is that, if uncontrolled, it may end up consume everything. An even better option is cold fusion, which eliminate that risk. The only challenge is that it require extremely high start-up energy, once it start, it takes little energy to maintain.

The whole idea of space exploration isn't just about finding habitatable environment for human race. But also about discovering other civilization, hoping to learn about their evolution, and perhaps some useful technology/history which could help us. Mars exploration means a lot. By understanding simple thing like how the weather changes, planet movement, it could help us to understand earth better.

Fusion is definitely the answer to space travel,but the problem is,ITER is still having financial isuues.The research is pretty much halted now.

What a waste.

Research still go on in small institution, like university research, except that at small scale. It's still in development, except that it's not that transparent to public.

Yes,but didnt they need a huge reactor to test it?

this is what i mean... due to financial issue, some research already been stopped/ halted... don't u guys think that research is also important? Yes, its important... but how important it is compared to other research... let say the research on fusion is in the top 10... others are just at the bottom 10. But due to financial problem... the stop the important research and continue with the one which is less important.

not sure how they prioritize those research... based of financial or its potential...

are u referring to Teflon? i though Teflon is accidentally discovered while they doing research on new CFC refrigerant...  unsure.gif

It was stopped because ITER cost much more than LHC,just to build that reactor plant.Not because someone thinks it's not important.Fusion is pretty much a huge challenge,not just from scientific point of view,also from engineering point of view.It's something very difficult to design but we are getting there slowly.

I dont think anyone is puts researches on some ranking.

Most of the stuff we have today are discovered accidentally.
