(PhysOrg.com) -- A physicist has proposed using a 1.1 km (3,600 ft) cannon to deliver cargo into orbit, and says the cost would be around $250 per pound, a massive saving on the $5,000 per pound ($11,000 per kg) it currently ...
By providing the first estimate of how much hydrogen is available to fuel microbial life in the sunless sub-seafloor crust beneath the Mid-Ocean Ridge (MOR), a new Duke University-led study sheds light on one of Earth's least ...
