The Bible very clearly predicts that all of man's utopian dreams will end in complete failure. The technology we thought would lift us to a higher plain of existence will ultimately be used for man’s destruction.
Once I realized the hopeless nature of our fallen state, I knew it was a lost cause to rely on science as any means of achieving eternal bliss. I eventually turn to an old-fashioned but highly proven means of redemption.
When believers in Christ arrive in heaven, I doubt there will be any need for flying cars. Jesus said we would be like Him, with an ability that is not subject to the physical laws here on earth. We may be able to just think of being in a distant location, and be instantly transported to that destination.
