$10 billion / year is a drop in the ocean compared to the annual war budget of $650 billion (plain disgusting), so it's sad to see you attack science that's helping us spread forth to other worlds and expanding out as a race. Stay on Earth and our resources will run dry. We attack our neighbours for what limited resources there are because we will see them as competitors for survival- a rascist world compared to the resource abundant one where humanity is global brotherhood pooling our brains to come up with new creative solutions.
It doesn't help us to spread in any way. It tries, but so far it has been a fantastic failure. And if $10 billion / year is that little of an amount of money, why don't scientists just finance it themselves, instead of stealing it from non-scientists ? And as far ar war budget is concerned, this is not an excuse. A bad doesn't justify an other bad.
When I see how humans are unable to just put some solar cells in Sahara for instance, or to explore resources in deep oceans, to me it just stupid to announce they want to go to Mars. This IS propaganda, you just don't realise it. They will spend trillions of tax money to go there, they will put a nice flag on the surface, and then they will eventually come back to Earth, litteraly.
There is almost no resource on Mars. Water ? Maybe. Minerals ? Sure. But most of the energy we use comes from the Sun (and we don't have to go to Mars to get it) and from fossilized biomass. Now, here is some news for you : THERE IS NO BIOMASS ON MARS ! It is nothing else than a huge desertic place. Show me you can fertilize the Sahara, and then I might take you seriously when you talk about going to Mars.
And again, I'm still waiting for you to justify why you would have the right to force me, via taxation, to work in order to help you to fullfill your silly dreams.
Human is a life form and as any life form it tends to spread. But as any life form it is designed to spread in a earth-like environnement, not a huge 0°C cold, irradiated, 1% thick atmosphered, unoxygened, nolifed land.
An asteroid hits the Earth and we all die out. Nice while it lasted.
Well this is a nice allegory of life, because I have an other big news for you : we will all die anyway.
Don't worry about what could happen in a few billion years. You will probably die in less than a century, anyway. You'd better start living with this idea. Enjoy present life, carpe diem, and don't live in fantasy.
