Does Gravity as a force really exist?
Does Space exert a repulsive force in the presence of Mass/Energy thereby creating a distorsion in Space that to us is Gravity?
Would this explain why Galaxies that should spin themselves apart but don't and why intergalactic space is expanding?
Would a Repulsive space push our Universe apart and force our Galaxies together?
Could this have a similar effect to Dark Matter that no one has seen and no one knows what it is.
Could there be a space particle or maybe an anti energy particle?

Maybe Santa exists.

Maybe Santa exists.

And maybe some foxes are not so sly!

Or maybe not.

pushing our Universe apart and forcing our Galaxies together.

This among others doesn't make sense, that sentence seems to contradict itself.

How does your theory explain the tides?

I think you're right, so lets stop the LHC, before it's too late.. [:-'(]

Repulsive force?
Yeah, I find undue 'force' repulsive too

[acsinuk]

The repulsive force is almost certainly electrical.  There is an alternative 3D electric universe concept details on blogger.
