Yes. In the post earlier today in this thread I discussed antihydrogen being
formed.

Finally, nanotechnology can now fulfill its potential to revolutionize
21st-century technology, from the space elevator, to private, orbital
launchers, to 'flying cars'.
This crowdfunding campaign is to prove it:

Nanotech: from air to space.

Good question. Positronium is not an exact analogue of a hydrogen atom
since it consists of an electron and a positron (anti-electron) orbiting
each other while the hydrogen atom has an electron orbiting around the
much more massive proton.


So why isn't it made of a positron in orbit around an anti-proton? That
would be an exact analogue, yes?
