    Big bang
In summary, the conversation revolves around the possibility of the Big Bang being a cyclical event and whether black holes play a role in this process. The conversation explores the idea that the Big Bang was precipitated by a contraction caused by massive black holes and that this cycle could be repeated infinitely. However, the question arises whether there would ever be enough mass in expanding black holes to allow for a re-contraction. The possibility of White Holes and the role of gravity in holding energy in the form of a magnetic field are also mentioned.

Could the Big Bang Have Been A Cyclical Event?

I am a layperson...this is a long-pondered question.

Is it possible that Black Holes serve a greater purpose...to facilitate a massive contraction...which will then lead to another big bang?

It's logical that the Big Bang was precipitated by a contraction. It would explain the consistency of matter. All matter could have been mixed together in a single contractive gathering of massive black holes...reached a critical point and exploded outward. The explosion could have also created new and smaller black holes...that would continue to grow as they travel outward (also - are all black holes shaped the same?). If the black holes could become massive enough they could re-gather and the cycle could be repeated infinitely.

The question is this...as the Big Bang started with a finite quantity of mass...and continues to expand infinitely...would there ever be enough mass concentrated in expanding and outwardly traveling black holes that would allow a re-contraction? Or, is the space/time of expansion too great to provide for a gathering and re-contraction?

How can this be calculated...at what distance will/did a re-contraction become impossible?

Interesting theory... but I'm not sure if that would even work. Black Holes have gravity so strong, that it destroys what ever goes in. So nothing actually 'builds up' in them.
And there are also theories of the existence of White Holes, which essencially are the opposite of Black Holes. Instead of sucking things in, they push them away.

When the black hole destroys whatever it pulls in and turns the matter into energy...isn't the gravity strong enough to hold that energy in the form of a magnetic field?

1. Could the Big Bang have been a cyclical event?

The idea of a cyclical universe, where the Big Bang is followed by a contraction and then another Big Bang, has been proposed by some scientists. However, this is still a highly debated topic in the scientific community and there is currently no conclusive evidence to support this theory.

2. What evidence supports the idea of a cyclical universe?

Some scientists argue that the cosmic microwave background radiation, which is believed to be leftover from the Big Bang, could be explained by a previous Big Bang and contraction. Other evidence includes the distribution of galaxies and the expansion of the universe. However, these pieces of evidence are not enough to confirm the cyclical universe theory.

3. Is the cyclical universe theory compatible with the laws of physics?

One of the biggest challenges for the cyclical universe theory is whether it is compatible with the laws of physics. Some versions of this theory suggest that the universe goes through an infinite number of cycles, which is not supported by the second law of thermodynamics. Furthermore, the theory also raises questions about the conservation of energy and the cause of the initial Big Bang.

4. What are the implications of a cyclical universe?

If the cyclical universe theory is proven to be true, it would completely change our understanding of the universe and its origins. It would also have implications for our understanding of time and the concept of infinity. However, until there is solid evidence to support this theory, it remains just a speculative idea.

5. How can we test the cyclical universe theory?

As with any scientific theory, the cyclical universe theory must be tested and supported by empirical evidence. This can be done through observations and experiments, such as studying the cosmic microwave background radiation and the distribution of galaxies. However, testing this theory is challenging and requires advanced technology and a deeper understanding of the universe.
