Hello, it is observable with the CERN collider... and quantum
physics...
The European Organization for Nuclear Research (French:
Organisation européenne pour la recherche nucléaire), commonly
known as CERN (see Naming), pronounced [sɝn] (or [sɛʀn] in French),
is the world's largest particle physics laboratory, situated just
northwest of Geneva on the border between France and Switzerland.
The convention establishing CERN was signed on 29 September 1954.
From the original 12 signatories of the CERN convention, membership
has grown to the present 20 member states. Its main function is to
provide the particle accelerators and other infrastructure needed
for high-energy physics research. Numerous experiments have been
constructed at CERN by international collaborations to make use of
them.

Anyway just ignore that guy, he has no idea what he is talking
about...
