A Brief History Of Time (Stephen Hawking) FAQs -- Big Bang & Multiverse question

Click For Summary

Discussion Overview

The discussion revolves around the relationship between the Big Bang theory and the concept of the multiverse, exploring the implications of inflationary models and alternative cosmological theories. Participants examine the validity of these ideas, their evidence, and the philosophical implications of accepting or rejecting the multiverse hypothesis.

Discussion Character

  • Debate/contested
  • Exploratory
  • Technical explanation

Main Points Raised

  • Some participants question how the multiverse could exist if the universe originated from the Big Bang.
  • Others assert that there is no evidence for the multiverse, suggesting it may be an unnecessary mathematical construct.
  • Some participants argue that the multiverse is considered real by parts of the scientific community, often linked to inflationary theory.
  • Concerns are raised about the implications of accepting the multiverse, with some suggesting it weakens the challenge to explain observable features of our universe.
  • Participants discuss the distinction between the "big bang singularity" and the "Big Bang Theory," noting that while the singularity may be problematic, the theory itself has merit despite its gaps.
  • Alternative models are proposed, such as those suggesting a contracting universe prior to the current expansion, challenging the notion of a definitive beginning to the universe.
  • Some participants highlight the limitations of General Relativity (GR) in modeling high-energy scenarios, questioning the existence of energy limits and the nature of singularities.

Areas of Agreement / Disagreement

There is no consensus among participants. While some agree on the lack of evidence for the multiverse, others maintain that it is a necessary consequence of inflation. The discussion includes competing views on the validity of the Big Bang theory and alternative cosmological models.

Contextual Notes

Participants note that the discussion involves complex theoretical models that may not be fully resolved, including the implications of quantum mechanics and the limitations of current cosmological theories. The nature of singularities and the accuracy of GR at high energies are also points of contention.

Being new is no excuse for bad manners and for asking too much of people as though they were your servants. As Vanadium said, you will get better results with a better attitude.

I also suggest, again, that you read the cosmology FAQ and a good way to get introduced to many of the concepts in cosmology. I'm sure that will keep you busy for quite a while and if/when you find anything puzzling, then start a new thread with specific questions. Don't ask people to write an entire textbook on basic science just for you.

OK man, calm down! I'm sure people have forgiven you by now.
Just remember that every time you have a question, you post a thread specifically for that question and as soon as the issue becomes clear to you, you stop posting in that thread. Any new questions should be posted as new threads.

Sounds good to me. Welcome to the forum ... despite your rough start I'm sure you'll learn a lot here.

Priyank, since you have moved on from your original question, this thread is closed. Please start a new thread for each separate topic, but also make some effort to read about the topic first as suggested, then if you don't understand something, explain what you've read, explain what confuses you and no more demanding an entire lesson be taught to you. If you can post a link to what you read that confuses you, it may help members determine what you specifically need help with.
