From Lorne Babcock:

Re: Other universes may be detectable, published study claims (Oct. 11): I have, for more than 40 years, believed that there are many universes, in fact a multiverse.

Let us look at this issue.

It was believed up until relatively recently that energy or matter could not escape from a black hole. It is now believed that in fact over N period of time, that sufficient energy could be drained out of a black hole so that it would collapse in on itself and create what we know as a singularity.

It is further believed that our universe was created from the ultimate explosion of a singularity. If that is true, and many scientists believe that to be true, then it is logical to assume that other black holes will have acted similarly over an indeterminate period of time. We can therefore postulate that there are as many universes as there have been explosions of singularities.

It is currently impossible to even envision where or how an adjacent universe might exist. It could just be a matter of vibrational frequency placing the adjacent universe out of our sight and reach but as nearby as the distance between two atoms. All pure speculation of course but of significant interest nevertheless.

It is conceivable that an adjacent universe, if that is the right term, might have produced intelligent entities who have found a way to travel between their universe and ours and that could account for UFO sightings.

I could go on here ad infinitum, ad nauseam, however I believe I have made my point.

I look forward with great interest to reading the articles on world science.net. Keep up the good work.
