I don't think that Smolin's model requires any black holes to explode (at least from our perspective). As I read his paper, I got the impression that what we consider a singularity in our universe (BH) might be viewed as a creation event from the viewpoint of a theoretical universe on the "other side" of that singularity. A variation on the multiverse theme, with multitudes of universes nested within, yet isolated from, each other by virtue of the BH singularities.Vast said:Some physicists have suggested that the big bang might have been a black hole. Lee Smolin for instance has speculated that instead of a singularity, black holes produce new universes. Has Smolin or anyone else for that matter given a process by which a black hole may explode? Apart from evaporation that is.
Lord Flasheart said:If I recall correctly, the only thing that can make a black hole explode is another black hole.
I am unsure of the parameters, or the variables involved, but I'd guess they would have to be around the same size. Hmm.
Turbo, your right. Smolin’s theory was probably a bad example as it implies that the big bang singularity in our universe is a black hole singularity in another universe, I was thinking along an alternative path where the universe is simply confined to within a black hole at its origin, or something similar such as would be produced if the universe were to collapse. What physical processes then would cause exponential inflation?turbo-1 said:I don't think that Smolin's model requires any black holes to explode (at least from our perspective).

A black hole is a region in space where the gravitational pull is so strong that nothing, including light, can escape from it. It is formed when a massive star dies and collapses under its own gravity.
Yes, a black hole can theoretically explode, but it is not a common occurrence. This explosion, also known as a supernova, would happen when a black hole consumes a large amount of matter, causing it to release an enormous amount of energy.
A black hole can potentially explode due to the process of accretion, where it absorbs large amounts of matter, or if two black holes merge together. The explosion would occur as a result of the intense gravitational forces and the release of energy.
No, an exploding black hole would not pose a threat to Earth as they are typically located far away from our planet. However, the explosion itself would release a huge amount of radiation and could potentially affect any nearby planets or objects.
It is possible to observe a black hole explosion through various means, such as detecting the release of energy and radiation. However, it is not easy to predict when and where a black hole explosion will occur, so it is a rare event to witness.
