Bold take to proclaim we'll figure out interstellar travel before we figure out how to prevent muscle atrophy.
- 383toast 2y agoalso bold take to proclaim we'll still have human bodies before moving up kardashev scale
- guerrilla 2y agoWe are human bodies.
- exe34 2y agoReplace it one cell at a time. Ship of Theseus awaits to set sail.
- guerrilla 2y agoBodies are processes, like chemical reactions or baseball games, not "objects." No problem.
- exe34 2y agoobjects undergo processes. atoms in your body are replaced over a period of hours-years.
- chimpanzee 2y agoIs a tornado an object or a process?
- reverius42 2y agoIs a thought an object or a process?
- exe34 2y agodoes a thought occur in a vacuum?
- exe34 2y agois there a lot of tornadoes in a vacuum?
- chimpanzee 2y agoJust one big one, afaik. I’m no vacuum engineer though
- srveale 2y agoHomo sapiens is subject to speciation just like every other animal. Then there's cyborgs...
- marcusverus 2y ago>98% of humans born in first-world countries reach adulthood and have the chance to reproduce. This number will asymptotically approach 100% as we ascend. Is speciation possible in such circumstances?
- srveale 2y agoSpeciation would happen over hundreds or thousands of years. I doubt the notion of first world countries will outlast that time frame, even more so the 100% reproduction opportunity. Isolated populations could come from space colonies, geographic isolation from war or extreme climate events, rich people with exclusive genetic upgrades, cyborg implants that make it possible to only reproduce with other cyborgs. Just off the top of my head. If you're less patient, give it enough time the old fashioned way and homo sapiens as they are today would eventually not be able to reproduce with their descendants. Genetic drift.
- chimpanzee 2y agoAmen.
- pk-protect-ai 2y agoalso bold take to proclaim, that humans will be required for teleoperation...
- 7thaccount 2y agoOne of the lead SETI researchers wrote about this and how biological life might just be a transitory phase.
- Mistletoe 2y agoWe already know how to prevent it, it’s called anabolic steroids or testosterone. Once I read a study that showed sedentary people on testosterone gained more muscle mass than people actually working out.
- automatic6131 2y agoBhasin et. al 2001. If you get in many internet fights about bodybuilding, it's an important part of your repertoire :-)
- schmidtleonard 2y agoIf you don't get in many internet fights about bodybuilding, testosterone can fix that too.
- dyauspitr 2y agoYes that’s how you get an enlarged heart and die by 35.
- GenerWork 2y agoI take it you're talking about people like Dallas McCarver, whose autopsy found his testosterone levels to be extremely elevated [0] because of the number and volume of substances he was taking. If you're just taking base TRT and actually do cardio alongside weightlifting, you'll probably be fine.

- dyauspitr 2y agoFundamentally the heart is a muscle and anabolic steroids and test stimulate muscle growth in muscles at a cellular level. There’s no way to have one and not the other. That’s just the tip though. They have all kinds of far reaching effects ranging from curtailing height, significantly reducing IQ, constant skin breakouts, altered moods, hair loss, severe anxiety, paranoia, kidney and liver failure, bone breakages etc, severe and permanent decrease in the testosterone you naturally produce etc.
- jeffreyrogers 2y agoWe know how already: exogenous testosterone (or other, more anabolic hormones), but that has downsides like left-ventricular hypertrophy, masculinization in women, and (usually reversible) infertility.
- loeg 2y agoYes, yes, it's safe to presume GP means "figure out muscle atrophy without the well-known terrible side effects of current treatments" from even a mildly charitable reading of his comment.
- yreg 2y agoInterstellar travel is not a prerequisite for K1 or K2.
- mperham 2y agoI think realistically we have to reduce our body mass by 99% if we want to go interplanetary, much less interstellar. It's extremely expensive to drag around 70kg of meat and minimizing weight is key to making solar sails work.
- owenpalmer 2y agoWe definitely don't need to reduce it for interplanetary travel.
- knowitnone 2y agoSure, let's remove 70kg. That'll get the ship moving...not.
- mperham 2y agoYou’re missing the fact that most of the weight of a spaceship is to support that 70kg and accelerate the whole thing. Watch this discussion about getting to Alpha Centauri. https://youtu.be/uZN5xjoS6TU?si=05xuUdWsWADrZY-i https://youtu.be/uZN5xjoS6TU?si=05xuUdWsWADrZY-i
- dmonitor 2y agothat's a fun thought experiment, but not at all practical
- samus 2y agoThe mass of the actual meatsacks inside the spaceship is barely anything compared to the rest of it. A true step forward would be to rengineer ourselves to be way smaller. Santi-like.
- mperham 2y agoThat’s what I mean, reduce us and the entire ship can be reduced too. We can’t go interplanetary with humans as evolved today. Solar sails can only push a very small payload.
- rbanffy 2y agoWill we even remember what a muscle is at that point?
- AtlasBarfed 2y agoIt's not just steroids and replacement testosterone. I recall certain classes of drugs that make mice into muscle-bound warriors, I believe using a different pathway then steroids.
- pvaldes 2y agoThis is the easiest part. Our bodies are not good for this task, so only frozen gametes should travel to be "assembled" on destination. End of the problem
