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!

neutralino, I also look forward to more knowledge on the early Black Holes. My thought at this moment is, that the early Black Holes where the factories that made E=mc^2 what it is. By adding the speed needed to change the early "waves" (dark matter), into all the factors, that would be included in "TOE". It would be exciting to see the jets and their composition of those jets coming out of the Black holes.

E=mc^2 is a law of physics which says there exists a rest-mass energy. A black hole cannot "create" a law of physics. So, as it stands, your thoughts are incorrect.

I have no idea what you mean by this!

When I see black holes acting in this way, I once again contemplate if black holes act as, "Big bang'ers". What I wonder is, if black holes take matter and reprocess it back into rays of different types. Do they take confined energy, and give it back as free energy. Adding free energy.

That's a great link Allen thanks.
One question regarding the article: Jets from supermassive black holes produce tremendous radiation in the form of X-rays, gamma rays and electrons traveling close to the speed of light. Evans said, however, that the X-ray and gamma-ray photons would ultimately do the most damage to planets
Why wouldn't it be at the speed of light, since it is light? Is it the interaction of space which appears to slow the speed?
Best to you,
Pat

Best,

Xrays and gamma rays are different frequencies of electromagnetic radiation. Thus, they will always travel at the speed of light. (I haven't read the link you're all talking about, so don't know whether this comment will be useful or not!)

Thanks Neutralino,
It's in post box # 4 above, it is an interesting post that you may be interested in. It is also very current.
Best.
Pat
