Just an idea I had after a few bored beers last Saturday at the Elephant & Wheelbarrow, whilst reading about Einstein and black holes...
According to
Wikipedia:
"As an infalling object approaches the singularity, tidal forces acting on it approach infinity. All components of the object, including atoms and subatomic particles, are torn away from each other before striking the singularity. At the singularity itself, effects are unknown; a theory of quantum gravity is needed to accurately describe events near it. Regardless, as soon as an object passes within the hole's event horizon, it is lost to the outside world."
To me, this opens up the possibility of a new universe opening up within a black hole, consisting of the information provided from objects that fell into it. From within the black hole, the creation of the new universe would appear to be a "big bang". This would mean that:
- if every universe can spawn black holes, the number of universes is infinite
- because our universe was created via a big bang, we are inside a black hole
- new objects being sucked into the black hole are the cause of expansion of our universe
I totally expect this to have been thought of, and much debated, already, but after a bottle of Shiraz and 5 minutes of Googleing I am unable to find this anywhere...
OK, I searched for 2 minutes more, and found this:
For example, matter that falls into a black hole in our universe could emerge as a Big Bang, starting another universe. However, all such ideas are currently untestable and cannot be regarded as anything more than speculation.
Due to the nature of the theory, there's not a lot more to say, and no proof able to be supplied. Still, it's my best bet as to part of the story of why we are here.
