Um, no. I'll hate on the people making the calls too. Sprint Telemarkers are legal, so it isn't a problem. They don't call me. The ones that call me when I am on the do not call list are not legal. They are doing illegal things, and they know it, and they don't care. Sociopathic. There are plenty of ways to make money without doing illegal things.
Oh yeah, all you need to do is tick one box (which is hidden deep in the settings). Give me a break. Only 2% of Android users know this setting exists. And Google knows it. That isnt in the Open Source spirit and you know it.
Yeah, I'm pretty sure it is Physics. You cannot make a REAL spacecraft that approaches any significant fraction of the speed of light. You would be dead before you got anywhere. You can talk about "Orion" or "generational spacecraft" but that is just scifi. You can't build one and launch one. All the money in the world isn't going to get humans out of our solar system.
