Primordial black holes (PBHs) are extremely old black holes that were made a long time ago; long before galaxies formed. We think that PBHs will exist out there somewhere, but we have no observational evidence for this at the present time. However, this may be soon to change: that is the main point of this article. Apparently, Planck, which is due to be launched sometime next year, will be capable of detecting PBHs. If we do detect any PBHs, we may will be able to peer even further into the past, and closer to the big bang. If we don't then, as stated in the final part of the article, we will be able to rule out some models of inflation that produce them. So it looks like either outcome of this particular part of the Planck mission will be a success!
