I'm not talking about white holes. Indeed, the big bang as the explosion of a black hole are an explosion of singularity.
At the beggining there was a singularity, then, the singulary expanded. So it can't be an explosion?Chronos said:An 'exploding' singularity? How might that happen? This is the kind of confusion Fred Hoyle probably envisioned when he coined the term 'big bang'?

Even colliding black holes will only produce a bigger back hole.
At the first there was singularity, then,from that, there is the universe. Then, singularity may experiment some change,don't?Drakkith said:A singularity is not an object that can expand. It's not really an object at all.

Bernie G said:what you mean by a black hole.
Bernie G said:Doesn't the "big bang" look like someone opened a big can of ultra-relativistic matter?
Bernie G said:That depends on what you mean by an explosion and what you mean by a black hole. Doesn't the "big bang" look like someone opened a big can of ultra-relativistic matter? (A lot like opening a bottle of warm soda.)

Nope. It looks like bread rising more than it looks like opening a can of ultra-relativistic matter.
Bernie G said:Its relative. If you're an armchair distant observer it looks like bread rising but if you're up close its like opening a bottle of warm soda.
The Big Bang theory is the prevailing scientific explanation for the origin of the universe. It proposes that about 13.8 billion years ago, all matter and energy in the universe was concentrated into a single, infinitely dense point called a singularity. This singularity then rapidly expanded, creating the universe as we know it today.
While the Big Bang theory explains the beginning of the universe, black holes are objects that exist within the universe. However, some scientists have theorized that a black hole may have played a role in the creation of the universe by releasing energy and matter, triggering the rapid expansion of the singularity and the universe itself.
While it is commonly thought that black holes suck up all matter and energy, they can also emit powerful jets of radiation and particles. These jets are created when matter is pulled into a black hole's intense gravitational pull and becomes superheated. However, this is not considered an explosion in the traditional sense.
There is currently no concrete evidence to support the theory that a black hole caused the Big Bang. This idea is still a topic of debate among scientists and further research and observations are needed to confirm or refute this theory.
The idea of a black hole causing the Big Bang is just one of many theories attempting to explain the origins of the universe. It is still not widely accepted or supported by evidence, but it does offer a potential explanation for some of the unanswered questions in our current understanding of the universe.
