Space-time vs. gravitons?
Quantum theorists argue for the existence of gravitons as the gravitational field. Relativists argue for the geometry of space-time as the gravitational field. Recently dark flow has entered the picture - one way to interpret dark flow is that there is universe beyond the observable universe. If so, would that not destroy the graviton concept?
They move and interact at light speed if real. Does String theory address this issue?
Dark flow should matter for the same reason as an observable universe - relative recessional velocities greater than light speed limit us to an observable universe - there is an event horizon. Would not that event horizon work for gravitons as well as photons? If dark flow is a gravity force of some kind surely spacetime curvature is the only known possible answer?
I speak of dark flow, not dark matter or dark energy - 3 different things
Oklatono, thanks - we are talking about the same thing - my question is, perhaps, poorly phrased. I'll have to try again.

It's probably not an either-or situation.
The simplest string you can calculate turns out to be the graviton, which is one of the reasons string theory is intriguing.

I'd go for the geometry of space-time over the graviton theory. But if gravitons are real, why would dark flow make a difference - apart from increasing the number of gravitons?
String theory addresses very few issues......

scientists currently looking for the graviton believe if found would be proof positive of inter-dimensional universes , however finding these they have to smash the same atoms ant protons together at tremendous velocity as to create a Miniature big bang hoping the graviton will appear .
I doubt what i said has any thing to do with what your talking about but hey 2 cents is 2 cents.

the graviton ws proposd way back in the day when it seemed likely that everything in the universe was somehow particle based... since no one has ever found, seen, or detected a graviton, that thoery really has fallen into disfavor... gravity is just a field, theres no particles
Dark matter and energy in NO WAY imply a universe beyond the observable universe.

They have nothing to do with one another. Dark flow and quantum .vs relativity I mean. However, I can assure you that a graviton must exist according to quantum theory. It would be almost impossible for gravity to have a general effect on atoms and not a particle one. We just don't have the tools to measure it yet.
Whatever mass is pulling the dark flow is visible to it, not us, because of its proximity to it, not ours.
