Ok, your universe theories is great, but look at it as at bobble wave "speed of light effect". We can see light crossing our planet at this only moment, we cant travel to anywhere so our planet and moment its 1 second, its same like u doing photo. If universe started 13+ billions years ago, then we see middle not at starting point, starting point is outside of us 13+ billions light years away, behind our baks. And center what u seeing with "Houble" its what happened 13+ billions years before us. So center can be 1 milliard years long but for us its be just empty space. we can see just belt around us of our crosing time, light wawes from all around us. So your theories is sorry but bulexcrements, u cant jump in yesterdays train u cant even see it after it left station after reflected light moved from him away at 5 minutes from reaching horizon't.
And at same time if we moving faster than light, then we traveling back in time, and caching up light waves what even older. And even in this point to us center is empty buble of time, not because its empty but because his light long gone. Our universe probably microsecond at someone atom collider, and cosmos black because they not put there light.
