  • People have very limited bandwidth. You can only dedicate so much energy to care about things at a given moment. Bedbugs aren’t a huge threat society wide, but individually they’re devastating. So if you spend a bunch of personal energy and effort on making sure you don’t bring bed bugs into your home, what things are you not paying attention to that normally would be a big deal?

    Viral outrage campaigns don’t need to be devastating on their own. Their purpose is to keep people distracted, tired, and apathetic.

    The fact that you think this is an embarrassingly unsuccessful endeavor implies to me that they are doing a good job obscuring their actual objectives.

    Anti hydrogen has been produced and detected in experiments. The energy transition levels are identical to normal hydrogen.

    In a newtonian view, two particles orbit the center of mass of the combined system. Since protons are 1836 times as massive as electrons, the “orbit” center would be very close to the proton. So it’s a bit like asking what would happen if we swapped the earth and sun. The orbits would change position, but the earth would still orbit the shared center inside the sun at the same orbital radius. So it would look essentially the same as it is currently, just with the center of the system having been shifted by one au.

    Clearly I’ve ignored all of quantum mechanics in this description, but the conclusion is the same. The nucleus and electron both have wavefunctions, but the mass difference makes the spread of the nucleus negligibly small compared to electron orbits. Swapping initial positions and momentum doesn’t really change the properties of the system.



  • Yeah, I have a hard time getting excited about a moderately more capable synchrotron and I have a Physics background. I’m not opposed to a larger synchroton, but I’m not confident that they’ll find anything particularly interesting like I was with the LHC.

    Personally, I’d like to see a bigger effort to develop high energy plasma Wakefield accelerators. I think they have the potential to work with a wider variety of particles and shouldn’t need months of pump down and cooling after any interruption. Plus minitiaturization of plasma accelerators have the potential to be disruptive for medical applications.
