The Amazing Rocket and America's New Supergun
It's amazing what we humans can do when we push the boundaries of science.
Like fire off this SpaceX rocket from Cape Canaveral in Florida, deploy a satellite.
Then land the first stage on a so-called drone ship in the North Atlantic.
And this is what a new and speeded up video of that landing looks like from the rocket itself.
Which is amazing, and a tribute to how far SpaceX's Elon Musk, who is also developing the Tesla electric car, has come.
But then there is America's new Supergun.
Which can fire off a high-tech projectile five times further than this World War II-era battleship with five times the impact...
And uses neither gunpowder nor explosives.
In conventional guns, a bullet loses velocity from the moment the gunpowder ignites and sends it flying. The railgun projectile instead gains speed as it travels the length of a 32-foot barrel, exiting the muzzle at 4,500 miles an hour, or more than a mile a second.
The Navy developed the railgun as a potent offensive weapon to blow holes in enemy ships, destroy tanks and level terrorist camps. The weapon system has the attention of top Pentagon officials also interested in its potential to knock enemy missiles out of the sky more inexpensively and in greater numbers than current missile-defense systems—perhaps within a decade.
Which can only make you wonder where we're going in our never-ending quest to find new and better ways to kill each other.
Or wonder why we're not investing more of our scientific genius and more money to develop new sources of energy, to wean us off fossil fuels before we torch our planet.
Or just make more use of the technology we already have, like Scotland is doing.
Which is charging ahead with renewable energy, even though it has oil.
With turbines on land, on the sea, and under it...
Or like Portugal just did, by running for four days on renewable energy alone
How much better off we all would be if we could get our priorities right.
Science. It can help save us.
Or it can help destroy us...
