Fecund Universe Theory: How Different Are Baby Universes?

In summary, according to Lee Smolin's theory of fecund universes, baby universes sprout off of ours through black holes with slightly different fundamental constants of nature. This theory, known as the CNS conjecture, suggests that the standard model and cosmology parameters are optimal for black hole production, a prediction that can be tested with current technology. The conjecture also proposes possible explanations for how these parameters became tuned for black hole production, including the formation of black holes in a previous universe leading to a slightly different big bang in the next one. This would ultimately result in a universe that promotes the production of black holes and, coincidentally, is hospitable to carbon-based life. The main question is whether or not these parameters are truly

According to Lee Smolin's theory of fecund universes, baby universes sprout off of ours through black holes, yet their fundamental constants of nature are slightly different. How different are they? Are they so different that life as we know it would not be able to exist in them?

Last year Smolin posted a paper on the current status of his CNS conjecture. If you are interested you can look it up.

As I understand it, the CNS conjecture is that the standard model and cosmology parameters are approximately optimal for black hole production (at or near a local maximum).

This is the sort of prediction that we can test with current technology and, in a sense, have already been testing for over ten years. It requires understanding the physics of stellar collapse and making observations. So far the CNS conjecture is still standing.

If, for the sake of argument, you accept the conjecture that the standard parameters (particle masses, coupling constants, cosmology constants...) are optimal for black hole formation, then you can think up explanations HOW it could have gotten that way.

One way is what you said, namely that the formation of a black hole leads to a bigbang but possibly with SLIGHTLY different values of some parameters, which just BARELY change the abundance of black holes in the next expanding region.

this would promote evolution towards a set of parameters favoring black holes and likewise (it turns out) favoring familiar carbonbase types of life but that is irrelevant to the conjecture. it just turns out that a universe tuned to produce a lot of black holes is also hospitable to carbonbase life on rocky planets around stable stars. Carbon chemistry helps in the generation of stars by providing pathways to radiate away heat. The fusion processes that yield heavier elements aiding star formation also provide the elements needed to make earthlike (rocky) planets instead of merely gas giants. So life is an irrelevant byproduct of an evolutionary process that favors the production of black holes, in this scheme.

I think the main question is not how to explain the odd coincidence that the parameters seem welladjusted for black holes. the main question is whether they in fact ARE approximately ideal for that! If they are that would certainly be very strange and require some kind of explanation.
 

Related to Fecund Universe Theory: How Different Are Baby Universes?

1. What is the Fecund Universe Theory?

The Fecund Universe Theory is a cosmological theory that suggests the existence of multiple baby universes, each with its own set of physical laws and properties. It proposes that our universe is just one of many that have been created and will continue to be created in an infinitely expanding multiverse.

2. How does the Fecund Universe Theory differ from other cosmological theories?

The Fecund Universe Theory differs from other cosmological theories in that it does not rely on the concept of a single, static universe. Instead, it suggests that universes are constantly being created and expanding, and that each one may have its own unique set of characteristics.

3. Is there any evidence to support the Fecund Universe Theory?

At this time, there is no definitive evidence to support the Fecund Universe Theory. It is still a theoretical concept and has not been proven through empirical observation. However, some scientists believe that future advancements in technology and observational techniques may provide evidence for the existence of baby universes.

4. How does the Fecund Universe Theory relate to the Big Bang Theory?

The Fecund Universe Theory does not necessarily contradict the Big Bang Theory, but it offers an alternative explanation for the origin and evolution of the universe. While the Big Bang Theory suggests that our universe began as a singularity and has been expanding ever since, the Fecund Universe Theory proposes that our universe is just one of many that have been created and will continue to be created.

5. Can the Fecund Universe Theory be tested or proven?

Currently, there is no way to test or prove the existence of baby universes, so the Fecund Universe Theory remains a theoretical concept. However, as technology and scientific understanding continue to advance, it is possible that new evidence may emerge to support or refute this theory.
