This is plausible but definitely requires references. I would not be surprised if it were something that can be seen in other mammalian species.

Do you really think a reasonable solution for deep space travel is to spend centuries in a spaceship? Don't you think some kind of suspended animation would be preferable?

Agreed. People already live quite long, so immortality would take a very long time to make a difference with how things already are. If the first person to live 150 years is twenty years old today, he will reach that age in 130 years, th

Bitcoin is both a currency and a payment method. Everybody knew right from the beginning that it's not a great payment method. The 10 minutes delay is a long time if you want to prevent double-spending. For fast payments nothing beat

I may be throwing a pie in the sky here, but is there any reasonable hope that AI will be able to design rocket engines, including ones based on advanced concepts like VASIMR, in the coming decades?

That's the purpose of magic[1], isn't it? Maybe one day magic tricks will be designed by AI. It'd be funny, since that would gave Arthur C. Clark famous quote ("any sufficiently advanced technology...") a whole new

I'm not sure I understand your question. Falcon Heavy has 27 engines because three times nine is twenty-seven. Are you suggesting SpaceX should have developed a bigger engine instead, and do something similar to a delta-IV heavy?
