Atrus6on What If Planet 9 Is a Primordial Black Hole?

Using dummy numbers. But, lets say you need to be going 100mph to escape the suns gravity. The Earth is moving around the sun at 75mph. So you only need to speed up 25mph to leave.

But to fall to the sun, you need to slow down 75mph. And speeding up and slowing down in space take the same amount of energy.

Atrus6on DIY Drones Take on Silicon Valley

Would you care to elaborate how you'll be able to power a drone for an extended amount of time? I was doing some minor research (I was curious about the pirate bays 'server drone' idea), and the best that I could personally come up with was flight times of about an hour. That doesn't seem all that useful to maintain a constant server, or traffic cam, presence.

Atrus6on How a big movie studio (unfairly) forced a student to give up his senior thesis
