    Exploring the Possibilities of an Accelerating Universe

    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...

    Exploring the Possibilities of an Accelerating Universe

    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?

    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...

    Exploring the Universe with General Relativity Theory

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

    Exploring the Universe with General Relativity Theory

    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...
