  1. Length contraction happens any time you travel anywhere at any velocity. You don't need to 'create' it. Length contraction only becomes noticeable at very high velocities however. Think of the distance you want to cross as a spring. The closer your velocity is to c, the more the spring is compressed. While you still have to cross the whole distance, there is less of that distance for you. Bit dated but this covers Relativity really well. Read it when I was younger and learned a lot from it. Happily online for free now. https://archive.org/details/TheUniverseAndDrEinstein/
  2. I'd wondered about that claim. DIY plans exist that could presumably be adapted to utilize Dyson parts, but was thinking something hospital-ready would take longer.
  3. Many also make use of metastable Argonite form of calcium carbonate instead of, or in addition to, Calcite. Rather impressive really, takes higher pressures to occur via physical processes. https://en.m.wikipedia.org/wiki/Aragonite
  4. lol, nice to see not too far off from what the real researchers are thinking. Obviously phagocytes exist so perhaps other cells can use the same method to engulf them when needed. Possibly they have some means to 'infect' a cell themselves too.
  5. Possibly. I know if I had my choice I'd use them to help repair/replace other mitochondria that have suffered damage, but I don't know if such a mechanism actually exists. We do know their distant ancestors entered the ancestral cell at some point however.
  6. Reading that it was previously found that platelets release them to promote inflammation. They are descendants of bacteria, so pretty logical that they can still trigger an immune response. https://ashpublications.org/blood/article/124/14/2173/33091/Platelets-release-mitochondria-serving-as
  7. It would be. I'm sure it'd take a ton to speed up that process. I've read a few analysis saying we could power our civilization for a thousand years with just a bit of that energy.
  8. Slowing down the Earth's rotation among other effects. Trading is okay, stealing is not.
  9. Unfortunately you can't steal energy from gravity(buoyancy = weight of displaced fluid). Going to at best break even, but will likely take more energy overall than you get back out.
  10. Provide the specs or name of the jumper. Not giving enough info to fully compare. The manufacturers save money buying the cheaper nigh endlessly recycled batteries. Most lithium car batteries are roughly $100 more. Now multiply that per car sold...
  11. Likely has a shorter lifespan or other undesireable characteristics. Main thing is that lead acid battery is mostly recycled material. You don't have to mine or ship as much material, keeping costs down.
  12. You can desulfinate or recycle lead acid easier.
  13. In labs, researchers typically only modify existing viruses. https://en.wikipedia.org/wiki/Smallest_organisms#Viruses This pandemic is understandably putting people on edge. Bad time to ask about how to make one yourself. Should really look into taking some of the free courses out there or buying a synthetic genetics/molecular biology kit if this is of interest. Link to a supplier as an example: https://amino.bio/
  14. That has been observed to occur. In one case I read about, they think it was due to a prolonged supernova. Fusion reactors in the sky.
  15. Right. See similar for people paralyzed or missing limbs using interfaces.
  16. Have to caution not to go too far down the rabbit hole as the person has to be Speaking. It could be easily picking up on what is being sent to the muscles.
  17. There are wakefulness promoters, but nothing like the fanciful Limitless pill.
  18. Incorrect or lack of grounding can result in the chassis to build up a charge along with everything connected to it(including the strings). Button works via running a small current through your skin so touching it is likely completing a circuit for the charge to flow out while the phone is charging. I'd look at what type of plug the guitar has and possibly check that the wiring for the building is correct. Can be a safety risk. I recommend seeking someone local to ask about it when you are able.
  19. If you search for bald monkeys and apes you'll see plenty of evidence for it being part of normal development. Not to say you can't want to change it based on cultural beliefs, but the fact that you are fighting your own biology is something to keep in mind.
  20. Still crude but they have found they can erase epigenetic damage. Mothers can gain cells that turn into neurons from their children so adding to the brain is doable in theory. No idea how a larger scale version impact the mind however. Not sure keeping the mind the same is really even feasible in the longterm as new memories keep being added. We'll probably need to add defect free clone cells while limiting the numbers of defective cells in the body. In theory just need everything to stay the same. Complexity of the task is the daunting part.
  21. I like using a bookmark for 'Unread' myself. Avoid cluttering up your feed that way. Additional filters are available too if you want.
  22. I've found games gloss over a ton. Lack of mechanical failures are particularly noticeable.
  23. Just to note, they were Money changers, engaged in the business of currency exchange.
