PeroK replied to the thread Undergrad My basic understanding of set theory.The basics are important. Things in mathematics are what they are defined to be. There is no single concept of "infinity" in... -
PeroK replied to the thread Alien life, probabilities, and interstellar propagation of human life.I think you underestimate the difference in scale and technical feasibility between living on a single planet and finding and moving to...

Like.
That sounds like a personal theory to me... -

True. Living in a cave in Antarctica would be far safer and more comfortable than living on a generation ship.

PeroK reacted to BWV's post in the thread Alien life, probabilities, and interstellar propagation of human life with
Agree.
A few months on the Mayflower, as bad as that was, hardly compares to generations in a dark void if society is rich enough to build all... -
PeroK replied to the thread Alien life, probabilities, and interstellar propagation of human life.That's true in the mathematical model of an infinite universe. The question is how relevant that is. We may never be certain that the...

PeroK reacted to Filip Larsen's post in the thread Alien life, probabilities, and interstellar propagation of human life with Like.
Assuming the drive for extrasolar colonization has been preceded by development of autonomous robotic vessels for mining, refining and...
-
PeroK replied to the thread Alien life, probabilities, and interstellar propagation of human life.It seems to me a no-brainer in terms of resources that any ship would carry the blueprint for life and not generations of live human...

PeroK reacted to .Scott's post in the thread Alien life, probabilities, and interstellar propagation of human life with Like.
One key phrase is "technology that we already know" - which is not the same as "technology that has already been developed". There's...

PeroK replied to the thread Alien life, probabilities, and interstellar propagation of human life.The last section sums it up, in my opinion: Unless all these steps are taken, humans cannot successfully travel to and inhabit other...

PeroK reacted to Hill's post in the thread Undergrad My basic understanding of set theory with Like.
Just to add to examples in the post #12, there are "points at infinity" in projective geometry, e.g.,
-
PeroK replied to the thread Undergrad My basic understanding of set theory.That has no relevance to mathematics. The meaning of infinity depends on how it is formally defined.

I would add "at any given point". Our technological civilization grew in just about 3k years (give or take, add a zero, divide by ten...
