Black Holes & Universes: Theory & Discussion

In summary, there is a theory called Cosmic Natural Selection that suggests universes can reproduce through black holes and that this process also creates conditions for life to exist. When two black holes merge, a larger black hole and gravitational radiation are produced. The probability of intelligent life creating tiny black holes in particle accelerators leading to the evolution of universes that support life is unknown. As far as current measurements show, the universe does not have net angular momentum like most black holes do. However, there is the possibility that what we consider as gravity could actually be angular momentum. The LHC at CERN may provide more insights into these theories and could potentially confirm the existence of super-symmetry.

There is a theroy that universes "reporduce" through black holes, and that part of the criteria that requires this also by coinsidence produces conditions that make life possable.

Discussion questions: What happens if two black holes merge?
If intellegent life creats many tiny black holes in particle accelorators, than universes would evolve to support life, is that probable?
Does the universe have net angular momentum, most black holes do?

You get a bigger black hole and a lot of gravitational radiation.

Until we can verify that such things even exist and that black holes actually do spawn new universes, that question is unanswerable.


Does the universe have net angular momentum, most black holes do?

As best we can measure right now, it doesn't.

The theory you are referring to is known as Cosmic Natural Selection and is most notably associated with professor Smolin, whose more mainstream work concerns loop quantum gravity.

Even if u manage to create artificially a micro mass black hole using accelerators in the future, u won't notice its pico second presence before it evaporates..
With the LHC(CERN) slated to be in place in 2007, ull witness some of the most interesting particle discoveries ever! and confirmation of super-symmetry theory would be one of them..

Unless what we call gravity is "really" angular momentum.
 

1. What is a black hole?

A black hole is a region in space where the gravitational pull is so strong that nothing, including light, can escape. It is formed when a massive star dies and collapses under its own gravity.

2. How do black holes affect the universe?

Black holes can have a significant impact on the structure and evolution of the universe. They can influence the movement of stars and galaxies, and can also play a role in the formation of new stars. Additionally, they can distort space-time and cause gravitational waves, which provide valuable information about the universe's history.

3. What is the theory of relativity and how does it relate to black holes?

The theory of relativity, proposed by Albert Einstein, is a fundamental theory in physics that explains the relationship between space and time. It predicts that the gravitational pull of a black hole is so strong because it warps space and time around it, creating a "well" that pulls objects towards it.

4. Can anything escape a black hole?

No, once an object crosses the event horizon of a black hole (the point of no return), it cannot escape. This includes light, which is why black holes appear black and invisible to the naked eye.

5. Are there different types of black holes?

Yes, there are three types of black holes: stellar, intermediate, and supermassive. Stellar black holes are formed from the collapse of a massive star, intermediate black holes are thought to be formed from the merging of smaller black holes, and supermassive black holes are found at the centers of galaxies and are millions or billions of times more massive than the sun.
