• Question: A magnet will attract certain kinds of metals, but is there some material which can naturally attract absolutely anything, without having to resort to gravity? Is there any theoretical chance of this (perhaps with nanotechnology)? Like-wise, is there some natural 'repelling' material? After all, atoms are doing this sort of thing all the time on a much smaller scale.

      No, I don’t think so. If you want universal attraction, then it’s Gravity.. or lynx?

      I don’t know of any material that can attract just anything, other than metal.

      I’m not aware of any such material. Fundamentally, I think there are only really four forces (if I’m remembering correctly), two of which act on really, really tiny (sub-atom) scales. So gravity and electromagnetism is really all we have. But I’m not a physicist or a material scientist …

      Good question. I don’t think this is possible but i’m not sure. Don’t think that anything would either attract or repel everything else
