Pressure on creation of the Universe

In summary, "Pressure on creation of the Universe" explores the scientific theories and concepts surrounding the origins of the Universe, emphasizing the role of various forces and pressures during its formation. It discusses the Big Bang theory, the influence of cosmic inflation, and the subsequent expansion and cooling of the Universe. The interplay of gravitational forces, dark matter, and dark energy is also highlighted as crucial factors in shaping the Universe's structure and evolution. The article concludes by considering the implications of these pressures for our understanding of cosmic history and the fundamental laws of physics.

TL;DR Summary
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.

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.
 

FAQ: Pressure on creation of the Universe

What is the concept of pressure in the context of the universe's creation?

In the context of the universe's creation, pressure refers to the force exerted by particles in a given volume of space, particularly during the early moments of the Big Bang. This pressure played a crucial role in the dynamics of the expanding universe, affecting how matter and energy interacted and evolved as the universe cooled and expanded.

How did pressure contribute to the Big Bang?

During the Big Bang, the universe was in an extremely hot and dense state, characterized by high pressure. As the universe expanded, this pressure drove the rapid inflationary phase, allowing for the separation of fundamental forces and the formation of basic particles. The high pressure contributed to the conditions necessary for the synthesis of elements in the early universe.

What role does pressure play in the formation of cosmic structures?

Pressure influences the formation of cosmic structures such as galaxies and stars. As regions of higher density formed, gravitational forces began to dominate, leading to the collapse of gas clouds. The balance between gravitational attraction and thermal pressure from the gas determines whether a region will continue to collapse into stars or disperse.

Can pressure affect the fate of the universe?

Yes, pressure can significantly affect the fate of the universe. The interplay between dark energy, which exerts negative pressure, and the density of matter in the universe determines its expansion rate. Depending on the balance of these forces, the universe could continue to expand indefinitely, slow down, or eventually collapse.

What is the relationship between pressure and temperature in the early universe?

In the early universe, pressure and temperature were closely related due to the ideal gas law, which states that pressure is proportional to temperature when volume is held constant. As the universe expanded and cooled, the pressure decreased, leading to changes in the state of matter and the formation of atoms and eventually stars and galaxies.
