Intro to Big Bang and Infinity Concepts - Comments

Click For Summary
SUMMARY

The forum discussion centers on the concepts of the Big Bang and infinity within cosmology, highlighting the distinction between the Big Bang Singularity and the Big Bang Theory. Participants emphasize that the Big Bang is not merely an event but a complex phenomenon involving the expansion of the universe from a hot, dense state. They clarify that the Big Bang Theory begins after the Inflationary Period, which is a critical phase not included in the theory itself. The conversation also touches on the implications of a finite versus infinite universe and the challenges in understanding singularities within the framework of general relativity.

PREREQUISITES
  • Understanding of Big Bang cosmology and its phases
  • Familiarity with general relativity (GR) and its implications
  • Knowledge of the Inflationary Period in cosmology
  • Concept of co-moving coordinates in spatial analysis
NEXT STEPS
  • Research the Inflationary Period and its significance in cosmology
  • Explore the implications of singularities in general relativity
  • Study the concept of co-moving coordinates and their applications
  • Investigate theories of eternal inflation and their impact on cosmological models
USEFUL FOR

Cosmologists, physicists, and students of astrophysics seeking to deepen their understanding of the Big Bang, its phases, and the nature of the universe.

Well how are we supposed to learn?
By studying what the current best fit models that are the result of many experts dedicating their professional life to a subject have arrived at rather than making up your own and arguing ”probably the thousands of people that worked on this never had this one particular thought of mine”.

Learning is not done by making up your own speculative theory. Until you know what the current models actually state and why that is a good description of nature, you are just going to speculate wildly in all kinds of directions.

Not by personal speculation. And certainly not by hijacking a thread that isn't yours.

What can I do but laugh at this response.
What can you do? You can earn yourself a thread ban, which you just did.

I strongly suggest that you take some time to learn what our current Big Bang model actually says. You appear to have some serious misunderstandings.

First of all, your attitude here is not a very good one if you are trying to learn. You are alienating the very people who possesses the knowledge that you seek.

CultQuantum said:
Current models, Is that required belief? Because correct me if I am wrong but nobody knows for certain that's why they're ahem "models"
You are wrong. They are the current models because they are what best fits the observational data. They are typically very good fits to the data with a small amount of anomalies that call for further investigation. Therefore, if you are to have any chance whatsoever to understand what is going on you need to learn why the current models are in place, the observations they describe at high accuracy. You are not required to believe anything. You are required to know and understand how the theory works and why. Note that you will only achieve this from years of studying the professional literature, not by reading popularized accounts.

Your personal speculation here is made even worse by being unmeasurable when you stipulate that maybe something exists that isn’t perceivable or measurable. That is an unscientific statement.

Learning indeed involves interaction and guidance. Not wild personal speculation.
