Pressure on creation of the Universe

Click For Summary
SUMMARY

The discussion centers on the theoretical implications of the universe's expansion and the concept of pressure during its creation. Participants emphasize that the universe is expanding uniformly, with all points moving away from each other, and clarify that there is no external space into which the universe expands. The conversation critiques the reliance on pop science literature, such as "How to Survive a Black Hole" by Jenna Levin, for foundational scientific understanding. Ultimately, the discussion concludes that the universe is defined as everything that exists, making the notion of external pressure or space irrelevant.

PREREQUISITES
  • Understanding of cosmic expansion and general relativity
  • Familiarity with the concept of gravitational binding in astrophysics
  • Knowledge of quantum field theory
  • Critical analysis of scientific literature, distinguishing between pop science and rigorous scientific sources
NEXT STEPS
  • Research the principles of cosmic expansion in the context of general relativity
  • Explore the implications of gravitational binding on cosmic structures
  • Study quantum field theory and its relation to the universe's creation
  • Evaluate scientific literature critically, focusing on peer-reviewed sources versus popular science books
USEFUL FOR

Astronomers, physicists, students of cosmology, and anyone interested in the fundamental nature of the universe and its expansion.

TL;DR
Pressure on creation
I had a question today as a part of my studies which was 1) If space is ever expanding what is the pressure on the creating space (universe) upon creation and 2) at what rate might you assume the quantum field is also being created and is it being affected by this pressure of creation. This is of course all theoretical and asking for what may lead you to create equations with principal.

Personally I sometime like to think as the universe ever expands and brings in reality its also very similar to a computer game in which a player travels through areas of a map waiting for it to load upon entering.

What gave rise to the question? Can you give a reference?

I ask because your question doesn't really make sense and more context might help.
 
If the universe is constantly expanding what forces would be working against this expansion. How would you evaluate it etc

That's not a reference and it's not very useful as context. You say "as part of your studies". What studies? You must have got these ideas from somewhere. Where?

I thought of this idea on my own after reading “How to survive a black hole” by Jenna Levin. Just going into deeper thought my curiosity about this question I formulated in my mind mustve been explained before however I cant find one.

This is a pop science book. Pop science books are not good sources for learning actual science.

Even given that, it's not at all clear how you got from whatever is in the book to the questions you posted.
 
Since there is no valid basis for discussion, this thread is closed.
 
Forgive me, Peter, I know the thread is locked but I just wanted to address this particular questions since it is so common:

That's not how expansion works. Expansion means that ALL points in the universe are moving away from each other (ignoring things like gravitationally bound areas). This already includes everything in the universe. There is no 'outside' of the universe that needs to be brought in. There's no 'outside' at all. The universe is, by definition, everything that exists, and is believed to be infinite in size and unbounded (though it could be finite and bounded). The universe is not expanding into anything.
