Re: Question from a theist on universal beginnings and entro

Just a point limecat, I don't think anyone here has been really making a claim that 'God doesn't exist because of X'. You've been making a lot of claims about how causality and etc dictate God must exist, and we've been debunking them. On entanglement: when you make a measurement of particles you do...

It's just that things are simply too new for someone to point to this and claim that it literally has no cause and then to stand on the comment as though it were fact.

Re: Capturing Asteroids in Earths' Orbit for Mining

Honest question - given that they're not really worried about the acceleration of the payload, would a controlled nuclear bomb work? It'd definitely weigh a lot less.

I'd also think that no-one else would be allowed to mine it for the same reasons that it's not allowed to start chopping bits off other people's satellites. Yeah, but the thing is that no-one is going to be able to cut pieces off your satellite and sell them for billions of dollars. Also, satellite...
