I leave it as an exercise for readers to come up with arguments for and against. Exercise THIS..... A lot of discussion has been about interstellar craft. Well, first, I was predicting about giant telescopes, not interstellar craft. Then I included a link to http://1mmph.yolasite.com/ , which is my (crude but message-delivering) website about a proposal for solar system exploration, not intersteller (yet). Interstellar, at near-lightspeed, to destinations within tens of light years, is at least THEORETICALLY, ULTIMATELY possible without violating the known laws of physcis. But that is some steps (and decades or centuries) beyond the giant telescopes for looking around our stellar neighborhood. High speed solar system exploration needs to happen before interstellar, also. 1mmph... Another dicsussion got going about Man's problem being inward. This is a whole big, other subject. At the earthly level, no one wants us to stop improving qualitiy of life efforts, through technology, social action, etc. But refusing to spend on scientific research until we have utopia, here, means no more scientific research. Also, scientific research can help with the improving of physical quality of life. At the REAL PROBLEM LEVEL: For the wages of sin is death, but the free gift of God is eternal life through Jesus Christ our Lord. |
