it was cool three hours ago, but discussion of this has basically constituted reposting the same fucking youtube video 80,000 times

why is everyone amazed by this
superconductors do this, they have been doing this for a long time.

i believe the general gist of it is that the superconductor is almost magnetic transparent, meaning field lines pass through it instead of attempting the bend around it to create a repulsive force. The superconductor is basically impaled by the field lines and cannot move within them without outside energy

room temperature superconductors are a fair ways off, since we're not really sure WHY superconductivity happens in some metals as opposed to others, or why it needs such a low temperature
