Does Cosmic inflation cause spacetime to move?

In summary, the conversation revolves around the topic of the big bang and its effect on spacetime. The conversation includes discussions about the nature of spacetime and how it was created by the big bang, as well as theories about multiple universes and their relationship to matter and spacetime. The conversation also mentions the lack of observational evidence for these theories.

I've thought about this a lot and have tried to find the answer but have been unsuccessful. In the event of the big bang did it inflate through spacetime without effecting it other than warping by mass or did it actually cause the spacetime to flow or move outwards with the inflation?

I'm sorry you are not generating any responses at the moment. Is there any additional information you can share with us? Any new findings?

You are thinking of space time as some sort of independent entity, an aether so to speak. It is not. The BB created space time, so obviously, it could not move 'through' it.

Natisrt, it may be more helpful to think of spacetime as a way of labeling the positions of objects in space and time, not as an "aether" or something which can move and flow.

Well I'm asking because Einstein theorized that outside of our universe there is no spacetime. Then you have so many theories of multi verses and how our universe could be a bubble, is that theoretical bubble just a group of matter or a bubble of matter and spacetime?

in one case, something like:

the bubbles: areas where the inflaton has decayed from a false vacuum to the ground state where it's no longer going through a super inflationary state

you start with an inflationary universe, different regions decay as above at different times forming non-casually connected "bubble universes", new ones keep 'popping' up (all sorts of things to work through to find it goes forever and regarding collisions or not, etc.)

Great idea, it merely lacks any observational evidence.

Heck, they almost had some, although now they can't be sure it wasn't just dust.
 

1. What is cosmic inflation?

Cosmic inflation is a theory in cosmology that suggests the universe underwent a rapid and exponential expansion in the first fraction of a second after the Big Bang. It is believed to have been driven by a hypothetical field called the inflaton.

2. Does cosmic inflation cause spacetime to move?

According to the theory of cosmic inflation, the rapid expansion of the universe caused spacetime to expand as well. This means that the fabric of spacetime was stretched, causing objects within it to move further apart.

3. How does cosmic inflation impact the shape of the universe?

Cosmic inflation has been proposed as a possible explanation for the shape of the universe. It suggests that the universe was initially flat, but the rapid expansion caused it to become curved or saddle-shaped. However, this is still a topic of debate among scientists.

4. Is there evidence for cosmic inflation?

There is strong evidence for cosmic inflation based on observations of the cosmic microwave background (CMB) radiation. The CMB is the remnant heat from the early universe and its uniformity and slight temperature variations support the idea of cosmic inflation.

5. How does cosmic inflation relate to the expansion of the universe?

Cosmic inflation is thought to have been the initial rapid expansion of the universe, while the current expansion of the universe is driven by dark energy. However, cosmic inflation is believed to have set the stage for the expansion we see today by smoothing out the universe and making it more uniform.
