Well, are you assuming that GR & QFT, our two most predictive physical theories, are fundamental and (therefore) that "currently understood" physics is complete?Are you suggesting currently understood laws are wrong? — tim wood
As you pointed out, the sun has plenty of resources, which we can make use of. So do other planets and moons, in terms of raw minerals and gases. — Marchesk
I think you've been taking science fiction too seriously; it is fiction after all! — Janus
How about shielding? If the question does not make sense, then you're out of your depth. — tim wood
this is true. The question begs itself, however unanswerable it may be, to be: is there understanding of physics that make space travel possible? — god must be atheist
I don't know; I see the continual rise of technological humanity as inevitably leading to the degradation of soils, destruction of habitats and extinction species; which which all ultimately be to our own detriment and possibly demise. — Janus
Btw, deep space travel is for machines -- the tinier the better -- Von Neumann self-replicating/nano-fabricators (e.g. Bracewell Probes), and not living organisms (re: hard radiation exposure is too lethal, transport size increases likelihood of hazardous particulate impacts, life-support limitations & extreme durations between destinations, etc which exponentially compound the costs/risks). — 180 Proof
Get involved in philosophical discussions about knowledge, truth, language, consciousness, science, politics, religion, logic and mathematics, art, history, and lots more. No ads, no clutter, and very little agreement — just fascinating conversations.
