Rahmuss, you need acceleration to obtain a result similar to gravity. If you have constant velocity, then you can´t have visible efects. Is similar to what happens in regular physics problems. About "dragging" you are right, I think if we have an accelerated universe then we have a force driving...

What if... Gravity is the consecuence of mass deforming space-time. But why mass deforms space-time? What if gravity is the consecuence of mass inertia in an accelerated universe. I can imagine a universe expanding at an accelerated speed that is being deformed by the inertia of the objects...

Which force drives the expansion of the universe? The mental model is a explosion and subsecuent expansion product of the presure of matter and energy, but is this right? The most probable model of the universe do not have limits, so matter and energy cannot push over boundaries of the...

Sorry, I do not live in Italy, I am far away in the southern hemisphere. I live in Argentina :smile:

As we know for general relativity theory we live in a universe with (at least) 4 dimensions, 3 directions and time. If we think that time must be in 90° with other dimensions we can imagine the universe as a hypersphere with time as radius. Make it easier and simpler and cut one dimension...
