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

Click For Summary
SUMMARY

The forum discussion centers on the relationship between the Big Bang and the concept of the multiverse, with participants asserting that there is no empirical evidence supporting the existence of a multiverse. Key contributors, including Garth and Viatcheslav Mukhanov, argue that while inflation theory has historically led to multiverse implications, recent models propose inflation without self-reproduction, thereby avoiding multiverse conclusions. The discussion highlights the distinction between the "Big Bang singularity" and the "Big Bang Theory," emphasizing that the latter remains a valid framework for understanding cosmic evolution despite its unresolved questions.

PREREQUISITES
  • Understanding of Big Bang Theory and its implications.
  • Familiarity with inflation theory in cosmology.
  • Knowledge of multiverse concepts and their critiques.
  • Basic grasp of general relativity and its limitations at high energies.
NEXT STEPS
  • Research Viatcheslav Mukhanov's 2014 paper on "Inflation without Self-reproduction."
  • Explore the implications of the Big Bang singularity versus the Big Bang Theory.
  • Investigate current models of cosmology that propose alternatives to the multiverse.
  • Study the limitations of general relativity at the Planck scale and its implications for cosmological models.
USEFUL FOR

Astronomers, theoretical physicists, cosmologists, and anyone interested in the foundational concepts of the universe's origin and structure.

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.
