Question about the fabric of space

[bawchicawawa]

Forewarned, I'm super layman.

Anyways, I've been wondering this all day from the thought of liquids needing less heat to boil under less atmosphere. Don't panic, i haven't JUST learned this, it just has provoked a thought.Is space expanding because of the momentum brought by the big bang, like a balloon being filled up with gas or liquid? Or is it expanding as if you poked a pin in that balloon and the hole grows bigger, from that pin point ,without control.
Is it possible that matter and space is like pudding on a flat tabletop, you pore it on the table and it will eventually flatten out fully and stagnate in movement.

Without a deeper understanding and knowledge of cosmology one must be very careful in the use of analogies. You may benefit from reading the balloon analogy sticky in the cosmology forum (the first thread, top of the page).

Thank you, phinds.

Thank you for your question! I can say that your analogy of the expanding universe to a balloon being filled with gas or liquid is a good way to think about it. However, there are a few key differences. The expansion of the universe is not caused by a physical force like a balloon being filled, but rather by the expansion of space itself. This expansion is driven by the energy and matter present in the universe, including the energy released during the big bang.

To address your question about the fabric of space, it is important to understand that space is not a physical material like pudding. It is a fundamental aspect of our universe that allows for the movement and interaction of matter and energy. The analogy you mentioned about pudding on a flat table does not accurately represent the behavior of space. Instead, space is constantly expanding and stretching, much like a rubber band being stretched.

As for the expansion of the universe, it is believed that it is happening at an accelerating rate. This means that the expansion is not slowing down, but rather speeding up. This is due to the presence of a mysterious force called dark energy, which makes up about 68% of the universe. This force is causing the expansion to accelerate, rather than slowing it down.

I hope this helps to answer your question about the fabric of space and the expansion of the universe. Keep asking questions and exploring the wonders of our universe!
