Tell me what you think: Theory?

Question

Okay, I have a theory that since the universe has mass (not just on Sundays), that:

1. The universes' shape is defined by it's own gravity
2. The universe battles between the pressure of the big bang, and gravity caused by all matter in the universe.
3. As you go closer to the center of the universe, because of (cyntrifical force/gravity), time maves more slowly (relatively); As you go futher away from the center of the universe, time moves faster.
4. A spherical barrier made up of all of the 4 properties of matter exists on the edge of the universe (unpenetrable, for obvious reasons)
5. In the hypothetical 'outside' of the universe, time moves atr an infinite speed.
6. At the center of the universe is a core singularity where all matter originated from.
7. The singularity of the universe acts as a black hole (infinate gravity, non-moving time).
8. The singularity has no mass, and is made up of remenant anti-matter nebulae from the big bang.

Let me know what you think.

If the universe started from a single point, and expaned in all directions and dimensions from there, should not that area still exist? In your example, just because we cant get there, the Earth has a core....?

okay, but take for example, 2D and 3D structures. we can explain more information about a 3D object in 3D than in 2D. Does that operate on the same principle for space, on the 4D scale? Could we then explain everything in nothing, and (obviously) nothing from everything?

I believe that my brain is going to click any second now and i'll get all of this..... until then, brain freeze....

Answer 1

This is not a theory, but an Hypothesis.
How do you propose to test it?
What evidence do you have to support your hypothesis?
A barrier made up of matter which could encompass the universe would be extremely massive, just how did it come into existence, while the rest of matter, during the Big Bang, ended up as fragments which coalesced into galaxies, dark matter, gas etc etc?

Of your statements, only the first 2 have (some) merit.

Time is an arbitrary term used to describe an abstract concept, it neither moves nor is truly measurable.

Of your last 2 statements, they are contradictory, if something has infinite gravity, it can not have zero mass.

This might seem harsh, but science is a harsh mistress. You just need something other than abstract dreams and statements to be right, no matter how much you want to be correct.

Answer 2

Sounds a lot like what everyone thinks, except perhaps for the terminology and a few exceptions.
2. The critical density is called Omega (the ratio between the actual density and the density needed to exactly balance expansion and gravitational collapse in the long run:

If Omega is greater than 1, the gravity will eventually win and the universe will collapse on itself. If exactly 1, gravity will slow down expansion so that after an infinite time, expansion will stop. If less than 1, expansion will never stop. Looks like Omega is less than 1.

3. The "centre" of the universe is not in the universe (or, if you prefer, the universe does not contain a centre). However, time flow does "slow down" in a steeper gravitational field.

4. According to latest data from WMAP (a probe observing the CMB), the universe may be infinite in spatial extent. Therefore no barrier. If not infinite, it is probably a hypershere "wrapped" around a centre that does not belong to our 3-D space (like the 2-D surface of a 3-D sphere, is wrapped around a centre that does not belong to the surface).

5. Sounds like a tachyon space.

6. If you consider 4-D space-time, it does have an "barrier" 14 billion years in the past, and that is a singularity from which all energy (which became matter) originated.

7. Black holes do not have infinite gravity. Otherwise, the first black hole to form would have instantly swallowed the universe.

8. We do not know much about the initial singularity. We suspect that our concepts of mass, time, distance would not make any sense. We already know that our concept of temperature in the initial singularity does not make sense.

Answer 3

1- There are many forces in play in the universe thus its shape is distorted. See latest model for the universe.

2-Because of same condition as in #1, the BB theory is just a theory that hasn't been proven. Other forces may cause the galaxies to move around.

3- Because of same condition as in #1, there might be no such thing as a center for the universe.

4- That is and idea that will be difficult to prove.

5- Time is an abstract concept invented by humans. Thus it can't slowdown or speed up.

6- #1

7- #1

8- #1

Answer 4

Thee is no center of the universe or edge to the universe. The universe has finite volume but no center or edge, in a 3 dimensionally analogous way to how there are a finite number of square miles on the surface of the Earth but the 2 dimensional surface of Earth has no center or edge. That is because Earth's 2D surface is curved in the 3rd dimension and the 3D universe is curved in a higher dimension (you could call it the 4th dimension, or not). The difference is that even though we are mostly stuck on or near the 2D surface of Earth, we really exist in 3 dimensions and can see the 3rd dimension, but we cannot see or detect the 4th dimension, or any other higher dimension. We can only describe it mathematically.
