What is the size of a singularity ?

According to theory our own universe was once a singularity, then came the Big Bang that bursted that singularity open.

We can see around us what came out of it.

But what was the size of that singularity, can a singularity be measured at all.

Will cracking a singularity open a new universe in a smaller dimension ?

Funny word that " dimension " can it be that unknown dimensions holds the 4 we know but in smaller or bigger dimensions. Was it a CERN physician at the dimension level above ours that created our universe in a collider.

This is a possibility if a thought singularity in space and not in relation to other objects cant be measured for size.

Someone sent a distress signal from the future and pointed out Newton as the saviour.

A singularity I think is in principle infinitesimal and infinitely dense, but in practice that may not be accepted. I think you raise a good question but I don't know what the criteria (if any) for big bangs are supposed to be.

There's been an idea of naked singularities dying and consuming space time around it at the speed of light, one that Hawking and Stewart 1992 got from running their model through a computer. They themselves and most apparently don't seem to believe in this result. One who does http://arxiv.org/abs/gr-qc/9312009v1 puts it as a local micro catastrophe, but apparently physicist Poisson accepts it in http://www.skyatnightmagazine.com/viewIssue.asp?id=1096 as a sort of danger in the universe in general. Perhaps how much of the effect depends on the singularity mass.

Such unstable naked singularities were thought quite plausible to emerge from LHC in http://arxiv.org/abs/hep-th/0110255 and



Anyway I can hear CERN say that cosmic rays strike us all the time not that they ever even considered this (they avoid this last paper - that includes 30 yr black hole lifetime - like the plague). In the cosmic ray case the collapsing naked singularity travels at virtually the speed of light, which isn't quite the same thing. Plaga agrees with me that questions remain about the safety of such a prospect. You'd have thought that such an expert on cosmic rays would have/ or would be listened to by CERN.

The trouble is, authors like CERN and that of the last paper I gave, seem to regard LHC research as necessary science, so they narrow or exclude their considerations for risk as a result.
