And you see the creation, birth and raising of humans without any human interaction as a more tractible solution than any spaceship... -
PeterDonis replied to the thread Alien life, probabilities, and interstellar propagation of human life.Those aren't the only kinds of child abuse. How do you know that the complete absence of interaction with human parents doesn't qualify... -

Sure. Like every other technology, "it's right around the corner". But you take it so much farther. We're not talking about tissue... -

Not at all. I'm saying PeroK is attempting to use "traditional sci fi" speciously, as if it only applies to solutions he doesn't find... -

Which is all well and fine to bolster your opinion. But you step into the realm intellectual arrogance when you declare your idea is... -

You mean, like I've read in so many sci-fi stories?? :oldgrumpy: With respect, this seems disingenuous, to imply that your take on the... -
PeterDonis replied to the thread High School True static equilibrium and effects on time.No, this is not a requirement. For example, you're perfectly justified in saying you're stationary as you type your posts here. But you... -
PeterDonis replied to the thread Graduate Wavefunction in the context of quantum physics.Yes. Yes. Both of these functions will be square integrable functions of one variable, so they are both elements of Hilbert spaces... -
PeterDonis replied to the thread Graduate Wavefunction in the context of quantum physics.This is not correct. Wave functions are elements of a Hilbert space--for example, the wave function of a single spinless particle moving... -
PeterDonis replied to the thread Alien life, probabilities, and interstellar propagation of human life.That's true, but I think the technological aspects of those challenges are already well within our capability. The aspects we still have... -

There is no such thing. Speed is always a relative concept and you can always consider yourself "at rest" or "moving". As physicists... -
PeterDonis replied to the thread Alien life, probabilities, and interstellar propagation of human life.On a time scale of thousands or millions of years, those things are highly changeable. To the extent they're constraints on that kind of... -
PeterDonis replied to the thread Alien life, probabilities, and interstellar propagation of human life.In half a century or so. That's an extremely short time on the scale of human history. Sure, but the time frames you're giving for when... -
PeterDonis replied to the thread Alien life, probabilities, and interstellar propagation of human life.On time scales of thousands or millions of years, the engineering realities can change drastically. The engineering realities of Stone... -

I think you underestimate the difference in scale and technical feasibility between living on a single planet and finding and moving to...
