There is, indeed, no physical evidence for them, but I suppose their interest lies largely in the proposed symmetry breaking in the early Universe which would have given rise to them. I understand there are people looking for unexplained gravitational lensing, which might the result of their presence.

My particular interest in them is that Gott and others argue for their possible use in achieving past directed time travel, which I enjoy arguing against. smile

There never was nothing.
