$this->bbcode_second_pass_quote('Repent', 'N')one of the 'Salvage economy' or going back to the stone age would be necessary if we go into space for the resources we need to continue civilized society.
The skeptics will be proved wrong, stellar space resources are vast beyond imagination, space mining and resource extraction is the long term key to mankind's future and survival.
Our own solar system has multiple planets, moons, asteroids and other bodies to mine besides the Earth. The sun emits limitless solar energy, essentially forever in human terms. Also, our solar system is only one star system in the galaxy; a galaxy with an estimated 400 billion other stars. Multiply that figure by 10-100 million galaxies, then calculate the real amount of resources available in space in terms of metal, solar energies from other stars, nuclear fuels, the list goes on and on.
We need to get off our little rock and narrowminded ways of thinking and get out there!
And how do you propose getting to these other stars?
Again, the energy requirement (as dictated by physics, not technology) to get to Alpha Centauri in one human lifetime is enormous. I don't think you appreciate the sheer scale of the problem.
The US spent nearly a full point of GDP in the 1960s on NASA. We managed to move the equivalent of a minivan from Earth to the moon, a mere 200,000 miles.
The cost to get to Mars, even under the most optimistic assumptions, is in the trillions.
There is nothing on Mars worth a trillion dollars. I don't care if the planet is covered in Hope Diamonds and Chanel No. 5.
We just can't afford to do it.
What makes you think there is anything in space that could be profitably extracted?
