^^ I think the op makes an excellent point, but I also think from the perspective of human enrichment, given that we have a finite amount of resources to spend on science, are particle physics and sending dogs into orbit really what we should be spending our resources on? How about spending it to eradicate malaria, to guarantee clean drinking in abundance water for everybody, to implement sustainable urban architecture, to have a trans-continental airplane that doesn't produce so much CO2, to eliminate cockroaches, to promise an airconditioner in every house, to have safe, clean, fusion based power plants, or to cure cancer? I think the fact that we waste so much of our scientific resources on nuking each other and having "my space flight is longer than yours" contests, rather than these scientific developments that make human life more comfortable, enjoyable and meaningful, is an indictment of the kind of scientific progress that is valued in our current society.
I don't see why this has to impede space exploration. And while I do understand the bias towards biology in many aspects, I really don't fully see why physics is always thrown under the bus for not being very "useful". Science doesn't work that way. Its not about people looking for useful things all the time and finding them that way, often science is about learning a lot of seemingly useless (outside of the academic sense) things and then combining them into something very useful. X-rays were discovered by accident and without fully understanding the medical applications. And graph theory far removed from anything in biology is today showing applications for cancer diagnosis. So things don't always go down the easy route, but we should explore every route to make sure that we aren't missing something. Also isn't education by its very virtue part of enriching human existence?
“How in the hell could a man enjoy being awakened at 6:30 a.m. by an alarm clock, leap out of bed, dress, force-feed, shit, piss, brush teeth and hair, and fight traffic to get to a place where essentially you made lots of money for somebody else and were asked to be grateful for the opportunity to do so?” Charles Bukowski, Factotum
"In our glorious fight for civil rights, we must guard against being fooled by false slogans, as 'right-to-work.' It provides no 'rights' and no 'works.' Its purpose is to destroy labor unions and the freedom of collective bargaining... We demand this fraud be stopped." MLK
