Human vision is limited and we can only see so far . If we traveled beyond our visual universe we do not know what is there after . As with 3d objects , as we move away from them they firstly become 2d before an eventually vanishing point . Now if we traveled x amount of distant away from our visual universe into ? space beyond , the event of looking back at our point sources will lead to our point sources of observation eventually vanishing , hence entering oblivion space with no direction to observe by point sources . Do we think oblivion space sounds a reasonable speculation of possible ?
