Hypothesis:
Dark matter is the fabric of spacetime itself.
When I speak about spacetime, I am referring to the fabric of spacetime.
This theory will alter the big bang in that spacetime existed before the big bang. Or another option is the big bang first released a large amount of empty spacetime at the beginning before it created matter within later spacetime. Think of a soap bubble, the bubble itself is expanding empty spacetime while the air inside is expanding spacetime with matter in it. I believe an empty vacuum of spacetime existed first, and the big bang happend in it.
Gravity effects spacetime by curving it as Einstein stated. Therefore the fabric of spacetime we can assume has mass. The curving is actually spacetime being compacted by higher gravity of the mass of matter. This means light will curve but spacetime is actually being compressed at the center of an object like a black hole, and therefore it must be stretched at a distance from the object.
The mass of spacetime is small. But since a galaxy is mostly empty spacetime, the mass of spacetime at that scale would be large. With the gravity of the matter in the galaxy attracting more spacetime, the mass of spacetime in the galaxy would increase to an equilibrium. This gathers enough spacetime(and its mass) to hold the out most matter in orbit.
Dark energy is said to be pushing the galaxy apart, but if empty spacetime exists outside the expanding bubble of the universe, the gravity of that spacetime would be pulling it apart instead.
I believe all proven physics is not broken by this theory. The mass of spacetime on a small scale would be negligible so Newtonian physics and General Relativity is still accurate at their scale. GR will need to account for the mass of spacetime at much larger scales though.
Some questions to be pondered:
1) How compacted can spacetime be and how stretched?
2) As spacetime is stretched and compressed how does it effect light?
3) As a black hole spins does it twist spacetime also? Is spacetime dragged around the black hole or just simply compacted in the center do to mass?
4) What is gravity exactly? (LOL naturally) Could it be a dimesion as time is?
I hope this explains my theory well enough. I am not a physicist, just fascinated by relativity and quantum physics. But of all the theories I have read and studied, I believe this explains dark matter(and dark energy) better and simpler. I also do not have the expertise to do the math calculations to prove or disprove this so I am hoping physicists will read this and consider it.

Hi.

It's the idea of being "outside the bubble of the universe" that worries me. We have no physics for anything that exists outside the universe. You seem to be implying that "outside of our universe" is just a place with much the same laws of physics - so it has spacetime and gravity works much the same etc. That's OK but then it would seem that this place is in fact already included in our definition of "the universe". Standard Cosmology tries to consider "the Universe" and not just restrict attention to our "observable universe". In particular, there often are places outside the observable universe in these cosmological models and they look and behave just like the place inside the observable universe.
I am hoping physicists will read this and consider it.
Well I don't work as a physicist for my day job but I have read it and considered it. Thank you.

I think I will address Ur reply next, to clarify this universal/cosmic confusion, once and for all, time.
Here is my prediction: you won't clear up anything and you will continue to post off topic/useless posts.

I'll cut it short. Classical physics says spacetime is an empty vacuum. Quantum physics says otherwise to the point there is no such thing as empty space.
Observable calculation of vacuum is of order 10^120 magnitudes of error. The remaining unobservable energy might be encoded in the ground state of the vacuum from off-shell particles, known also as virtual particles, which do have real effects in spacetime. One promiment argument why we cannot observe these dark energy effects is because these ground state fluctuations normally have a lifespan too short to be observable. We can detect them though indirectly using very special mechines, so we know it's there.
So to answer your question, yes, the vacuum may be linked in this way to dark matter effects.

This is very plausible and likely as it explains the current understanding and physical universe. Thanks for your post.
