We're still a level 0 civilization. Thinking about space when we haven't even solved the energy problem is jumping the gun so to speak. Personally, I don't even think any human has actually gone to the moon yet. Come up with an alternative fuel, and solve the problem of breaking through the radioactive barrier surrounding Earth, then we can start talking about sending people out into deep space.
There is always a debate whenever space travel is evoked on wether it is useful to do so considering the problems that we allready have. There are many arguments back and forth, the better ones being "The more we wait the harder/easier it will be to leave. (taking into account various factors (geopolitical, ressource based, societal, scientific))", "Working towards space/earth development will help with earth/space development" and the final pairing of "Space is so big we'll never get anywhere anyways"/"If we stay only on one planet we are sitting around for : 1)an asteroid; 2)overpopulation; 3) ressource depletion to kill us.
It is true that we are a type 0 civilization, level 0 on the Kardashev scale, and that is a problem and it is true that by solving the energy problem we would solve many, many problems alongside it. And the energy solution and the liberated ressources could then be applied to space travel.But to me the benefits of trickle down science that space travel encurs is more beneficial in the long term and easier to attain than cold fusion (I jest with cold fusion of course *wink*).
I would love to have a more intricate talk about why you think we haven't gone to the moon but I'll let it drop and address the radioactive barriers problem you evoked, which is still a problem as you say but one to which we have found ways of negating, mitigating and working around, through radiation hardening of our spacecraft components and the shutting down of key ressources when passing through particularly high radiation zones of the barriers. So they are an inconvenience more than a problem.
Doing research for this post I found this article about a
company that even had a plan to eliminate almost completly the inner radiation belt using magnetic tethers linked with sattelites but I digress. Quite interesting stuff.
To finish off, I would say that space has the advantage of making people dream and wonder. That is a great motivator that projects working down on earth sometimes lack. Tahnks for the contrary post, it's nice to have different view points.
Mmh. Might make a SD post on this.
