  1. Am I missing something? Why would you bring it back here, where it would be really, really expensive nickel-iron, or really, really expensive platinum? I don't have numbers, but terrestrial mining has to be a lot cheaper in almost every aspect. Does not having to pay for mineral rights offset asteroid mining's inherent challenges and their costs, which include identifying and safely bringing the metals back to Earth? We can keep the metal out in space to build HE3 gathering facilities, something we'll need more of for quantum computing and medical imaging. Not sure how I feel about mining the moon for it, but we don't need much to make a big difference and it's in limited quantities on Earth. It makes more sense to bring this back. Anything we don't have to send offworld is a resource we get to keep, so I think it makes sense to use what we find out there out THERE as much as possible. At some point, we'll need the metals from asteroids for more projects out there.
  2. This had to be it. "I didn't spill coffee on the electrode, I applied a caffeine/sugar solution in the hopes of increasing fuel cell efficiency!"
  3. Analogy doesn't help much with this. It confuses things further. Very simply, so simply that it can't possibly be held to any degree of accuracy: the universe was extremely small, the matter in it was extremely dense and therefore extremely hot, and then the universe (which is everything there is) expanded rapidly (and the last point, working backwards, at which we can accurately measure it is what we call The Big Bang). At some point, the density of matter decreased enough to allow space between it to form, and the temperatures continued to fall. It could be that all that matter squeezed so small is similar to what happens in a black hole, but black holes happen inside the universe, and particles that fall inside are measured relative to the black hole, and no velocity can change that. When the whole universe is inflating itself so rapidly though, everything is different because everything is moving and expanding, everything in the universe is participating in the event. And I've probably made it worse.
  4. Mining asteroids makes economic sense only if you leave the metals out there, for use in outer space endeavors. Imagine having tons of metal to work with that you didn't have to bring up from Earth's surface a few kilos at a time at hideous cost.
  5. That's not a level of knowledge, that's an age range. We're a science DISCUSSION forum. We talk about science topics. Videos are difficult to discuss, and take a fixed amount of time to view. We prefer the written word, where we can assess a post very quickly for veracity and accuracy. We can talk about subjects for your channel, but we have no interest in helping you promote your channel, which is usually what people want when posting their own videos here. We would love to talk about Earth Science with you. Watching you talk about Earth Science? Not so much.
  6. So it's similar to a pottery wheel with a manual foot pedal, except it's function is just to rinse the mop?
  7. ! Moderator Note If it's here, and in a mainstream science section, it WILL be a discussion or it will be closed. I'm not sure what form you think feedback on this matter will take, but here at SFN, it's going to be discussed. If you have a viable alternative, we can discuss it. Oooh, the irony!
  8. ! Moderator Note I have to move this out of Quantum Theory, but I really have no place to put it. Can you support an argument for this concept in Speculations? It's hard to see how you'd do it. I'll put it in the Lounge for now. I also have to say that science discussion works SO much better when you stick to mainstream explanations. You seem to be looking for woo where reason and evidence are the usual standards. Lots of actual studies are available on the topic of thoughts affecting experiences.
  9. ! Moderator Note Or at least this thread. We seem to be done with reason here.
  10. This seems unproductive as a form of belief, discarding one extraordinary explanation for another. Neither angels nor extraterrestrials have as much supportive evidence as virtually ANY other explanation. Weather balloons are more likely than Michael or Martians.
  11. Are you sure you want to use a platform that forces users to look for help outside the platform's own website? If I'd paid for this, I'd be really mad if they couldn't help me.
  12. This happens to me sporadically. Clears right up if you reload the page. I suspect it's a browser issue, but perhaps we should mention it to the Admins to see if it's an Invision bug.
  13. I would imagine there's a point where the stability of having so many legs is overshadowed by the inefficiency of having to move them all, especially on a bigger world with more influence from gravity.
  14. ! Moderator Note It's against our rules to require anyone to watch a video or go offsite in order to participate in a discussion. Please give a summary of the concept you want to talk about.
  15. ! Moderator Note Moved to Speculations due to non-mainstream claims.
  16. Not to imply that, if Biden died, Harris would have to use the petulant kid as VP. She would get to pick her own.
  17. That's not what my example is showing. The doors closing faster than you can walk is what blocks you, not the doors themselves (you can stop the doors from closing if you get there in time). But there IS a temporal obstacle, the fact that the doors will close before you can WALK to them. Why do you need objects? The advance of time keeps you off the elevator unless you speed up your pace. Nothing spatial changes, but if you want to get on that elevator, the obstacle is time, and you're capable of using it to get on the elevator.
  18. He promises to shift major resources over to immigration control, including the largest domestic deportation in history. He promises to close the Dept of Education and give control over to individual states re teaching children. This will include putting prayer back into the classrooms. He promises to remove the Affordable Care Act, and replace it with a much better plan which he's never revealed before. He promises to cut all spending on gender affirming care, calling it "child mutilation". He also wants provisions to prosecute doctors who have EVER been involved in gender affirming care. He also promises to kill all efforts at producing electric cars, replacing the technology with flying cars that feature vertical takeoff. And he promises to put a 60% tariff on goods from China, because apparently everyone has forgotten the damaging costs of his last tariffs. And he wants every American to carry a concealed weapon, probably because we'll need more slave prison workers if we're going to deport all the immigrants. Best way to fill the jails is to increase the number of guns on the street.
  19. I see you walking before you jump. I directly observe that you don't walk and jump at the same time. ALL directions, including the linear one that time follows. Time can be just as much of an obstacle affecting movement as three-dimensional matter. If the elevator doors close in three seconds, you may not have the time to walk. The doors may be an obstacle spatially, but it's the temporal obstacle that will keep you off the elevator. It seems to me we move exactly like that, and we observe that we can run for the elevator door instead of walk, changing nothing spatially about the elevator, but making it inside before the doors close this time.
  20. Painter's tape. Over here, it's blue and has the feel of masking tape, but you can use it to mask what you don't want painted and later peel it right off.
  21. I think this is Special Pleading. Dimensions are all fairly abstract concepts meant to locate or measure certain properties of an object. We observe that time moves differently depending on the observer, so we know time is coupled with the spatial dimensions. I don't understand why you say it's not really observable as a dimension. Is it because you can see and touch something with three spatial dimensions, but feel time isn't involved in the interaction?
  22. At some point, I think historians are going to blame a LOT of the stupid in this country on FOX News and how they train uneducated people to misunderstand things. Maria Bartiromo had an economist on her show yesterday warning us of rampant inflation under Biden partly because of "faster wage growth". He literally claimed that we have to get wage growth under 3% or it's going to be very bad for the economy. No pushback at all from Maria. Huh. It's one thing to only tell TFG fans what they want to hear because you don't want to lose them as viewers, but this should be a criminal offense, imo. Most of these viewers still think the news isn't just entertainment, that it can't outright lie.
  23. I've seen folks bale up tumbleweeds to make insulation for sunken gardens. There's usually some property the material has that lends itself to making something with it. Will the pulp from dried tomato leaves make paper? Is there a pleasant aroma? Can you make tea out of them, or cook with them? Is there an animal or bug that either adores them or hates them?
