Re: Science fleeting thoughts

As I understand it, two objects in expanding space naturally move apart exponentially. Then you should be able to collect energy by lassoing an object a billion light-years away and gather the heat from friction as the rope slips through your hands....I think. But the Joules of energy now in your h...

Because when we use the mathematics that assumes such, we can produce accurate predictions.

Have you made any predictions by assuming your case, better than predictions using the current method?

If so, we're gonna need to see the math.
